1.1 area

To set busy tone type detection for ports, use the area command. To return to the

default, use the no form of this command.

area { north-america | custom | europe }

no area

Syntax Description

north-america The busy tone type of the switch connected to this interface is of North

America standard.

custom The busy tone type of the switch connected to this interface is defined by the

users.

europe The busy tone type of the switch connected to this interface is of Europestandard.

Default

By default, europe busy tone type standard is set.

Command Mode

Voice-port configuration mode

Usage Guideline

This command is used only for 2-wire loop trunk interface FXO, and it can only performconfiguration to the first port on the voice interface card. If successful, the configurationwill be effective for all the ports of the voice interface card.

When this interface is connected to a common user line of a program-controlled switch,

if the user on the switch side hooks on first, only by detecting the busy tone can the

router know the user on-hooking operation. Since different switches execute differentprompt tone schemes, there exist different frequency spectrum characteristics. Thiscommand is used to set the frequency spectrum characteristic used by the router todetect the existence of the busy tone.

Example

! The following example uses north-america standard to detect the existence of thebusy tone on port 0.

Quidway(config-voice-port0)# area north-america

1.2 cancel-truncate

To cancel the truncating of a called number, use the cancel-truncate command. To

return to the default, so as to truncate a called number, use the no form of thiscommand.

cancel-truncate

no cancel-truncate


6/84




1-3

Default

By default, truncate a called number.

Command Mode

Dial-peer configuration mode

Usage Guideline

In common cases, if the structure of POTS dial-peer type is defined on the FXO, E&M

or E1VI interfaces, and the destination-pattern is configured with a wild-card .,then

when the router receives an incoming call, it will truncate and delete the fixed numberbefore the wild-card by default, and only transmit the number to which the wild-cardcorresponds from this interface.

Whereas if the function of cancel-truncate is configured, a called number will not be

truncated, and all the numbers received will be transmitted from the trunk interface. Forinstance, a POTS dial-peer structure is configured on the FXO interface, thedestination-pattern is configured as 9 . (the four dots as the wild-card), then when

the router receives an incoming call whose number is 91234, the router will delete the 9on the FXO interface by default, and transmit only the 1234 through the FXO interface;ifcancel-truncate is configured, the router will transmit the whole number (91234),

without deleting the 9. This function enables routers to flexibly process numbersaccording to different switches at the remote end.

Example

! The following example configures POTS dial-peer, the number before the wild-card is

9, and transmits all the received numbers from the FXO interface.

Quidway(config-peer-pots1)# destination-pattern 9....

Quidway(config-peer-pots1)# cancel-truncate

Related Command

destination-pattern

1.3 codec

To set the voice codec mode according to priority level, use the codec demand. Toreturn to the default, use the no form of this command.

codec { 1st-priority-level | 2nd-priority-level | 3rd-priority-level | 4th-priority-level }

{ g711alaw | g711ulaw | g723r53 | g723r63 | g729r8 }

no codec { 1st-priority-level | 2nd-priority-level | 3rd-priority-level | 4th-priority-

level }

Syntax Description

1st-priority-level Indicate the first selected voice codec method.

2nd-priority-level Indicate the second selected voice codec method.

3rd-priority-level Indicate the third selected voice codec method.

4th-priority-level Indicate the fourth selected voice codec method.


7/84




1-4

g711alaw Indicate the A-law coding mode of G.711 (defining the pulse code

modulation technology), the bandwidth is 64kbit/s, usually adopted by Europe.

g711ulaw Indicate the -law coding mode of G.711, the bandwidth is 64kbit/s, usually

adopted by countries of the North America and Japan, etc.g723r53 Indicate G.723.1 Annex A (dual-speed voice coding of multi-media

communication, based on multi-pulse, multi-level quantization and code excited linearprediction technology) coding mode, the bandwidth is 5.3kbit/s.

g723r63 Indicate G.723.1 Annex A coding mode, the bandwidth is 6.3kbit/s.

g729r8 Indicate G.729 (the voice coding technology using conjugate algebraic code

excited linear prediction) coding mode, the bandwidth is 8kbit/s.

Default

By default, g729r8 coding mode is set.

Command Mode


Usage Guideline

Use codec command to specify voice codec modes of different priority levels.

g711alaw and g711ulaw coding provide high-quality voice transmission, but occupy

greater bandwidth.

g723r53 and g723r63 coding provide silence suppression technology and comfort

noise, the relatively higher speed output is based on multi-pulse multi-quantitative leveltechnology and provides relatively higher voice quality to certain extent, and therelatively lower speed output is based on the code excited linear prediction technologyand provides greater flexibility for application.

The voice quality provided by the g729r8 coding is similar to the ADPCM of 32kbit/s,

having the quality of a toll, and also featuring low bandwidth, lesser event delay andmedium processing complexity, hence it has a wide field of application.

Only when there is an intersection (a codec mode recognized by both parties) in the

voice codec modes owned by the two communication parties can the two partiesestablish normal communication with each other. If there is no consistency in the codecmodes set for the equipment at the two ends connected to each other, or there is nocommon codec method, the calling will fail.

Example

! Then following example configures to select g723r53 codec method first, then to

select the g729r8 codec method.

Quidway(config-peer-voip2)# codec 1st-priority-level g723r53Quidway(config-peer-voip2)# codec 2nd-priority-level g729r8

1.4 comfort-noise

To enable comfort noise setting, use the comfort-noise command. To disable the

comfort noise function, use the no form of this command.


8/84




1-5

comfort-noise

no comfort-noise

Default

By default, comfort noise setting is enabled.

Command Mode


Usage Guideline

The command comfort-noise is used to enable comfort noise setting. When the

silence detecting function on a corresponding voice dial-peer is enabled, somebackground noise can be generated by using the command to fill the toneless intervals

during a conversation. If no comfort noise is generated, the toneless intervals during aconversation will cause the interlocutors uncomfortable.

Example

! The following example disables comfort noise function on voice port 1.

Quidway(config-voice-port1)# no comfort-noise

Related Command

voice-port vad

1.5 connection

To specify a connection mode for the voice port and the E.164 telephone number of the

destination end, use the connection command. To disable the specified connectionmode, use the no form of this command.

connectionplarstring

no connectionplar

Syntax Description

plar Indicate to select PLAR (Private Line Auto Ringdown) connection mode.

string The E.164 telephone number of the destination end, and it may include thewild-card ..

Command Mode


Usage Guideline

The connection command is used to specify aconnection mode for interface. When

parameterplaris used, the stringconfigured will serve as the called number of all the

calls incoming to this voice port, i.e., after off-hook, the user need not perform anyoperation and the system will dial out the string as the called number automatically.


9/84




1-6

If the connection command is not configured, when the interface enters an off-hook

status, the standard session application program will generate a dial tone until enoughnumbers are collected and the call process is completed.

Example

! The following example sets an automatic dialing to 5559262 after off-hook on the

voice port 1.

Quidway(config-voice-port1)# connection plar 5559262

1.6 description

To configure an interface description character string, use the description command.To delete the interface description of character string, use the no form of this command.

descriptionstring

no description

Syntax Description

string Interface description character string, and its value range is 1 to 255 characters.

Command Mode


Usage Guideline

With the description command, make a description of the voice-port connection. Thisoperation will not have any influence on the interface running, only when the showcommand is being executed will the configuration information be seen.

Example

! The following example identifies voice port 1 as connected to laboratory lab_1.

Quidway(config-voice-port1)# description lab_1

1.7 destination-pattern

To configure the destination mode of a dial-peer, namely, to use a prefix or a wholeE.164 number, use the destination-pattern command. To cancel this setting, use theno form of this command.

destination-pattern [ + ] string[ T ]

no destination-pattern

Syntax Description

+ Used as the first character to indicate that this is a standard E.164 number.

T Control character, indicating that the dial string is a string whose length is variable(used in Europe).


10/84




1-7

string Indicate E.164 or digits of a private telephone number. The effective input is:

l 0 - 9, # , * .l , , indicating a pause between digits.l . , used as a wild-card, indicating that it can match any input digit.

Command Mode


Usage Guideline

Use destination-pattern command to define an E.164 number for a dial peer, so as to

match the dial to this dial-peer. If successful, the call will be completed by the dial-peer.When the command is used to set the E.164 telephone number, and when the router

receives a call request, it will strip off the mode string according to the telephonenumber carried in the message. If a prefix is configured, the prefix will be added to thetelephone number carried. If all the modes are successfully matched, the user will hear

a ring back tone.

& Note:

VRP software does not verify the validity of an E.164 number.

Example

! The following example sets 5557922 as the telephone number of dial-peer 10.

Quidway(config-peer-pots10)# destination-pattern +5557922

! The following example sets 66 . as the destination mode of dial-peer 20.

Quidway(config-peer-pots20)# destination-pattern 66....

Related Command

1.8 dial-peer terminator

To set a special character string as the terminator of a telephone number whose length

is variable, use the dial-peer terminatorcommand. To cancel the existing setting, usethe no form of this command.

dial-peerterminatorcharacter

no dial-peer terminator

Syntax Description

character Telephone number terminator. The valid characters are: 0 9, # , * .

Command Mode

Global configuration mode


11/84




1-8

Usage Guideline

In areas where telephone numbers with variable are used, a character can be specified

as a terminator in order to avoid that the system cannot dial until the dial is timeout.

Example

! The following example configures using # as a terminator.

Quidway(config)# dial-peer terminator #

Related Command

destination-pattern timeouts

1.9 dial-peer voice

To set a voice dial-peer and enter its configuration mode (at the same time specify the

working mode related to voice), use the dial-peer voice command. To delete anexisting voice dial-peer, use the no form of this command.

dial-peer voicenumber{ voip | pots }

no dial-peer voice number

Syntax Description

number Identify a voice dial-peer, The value range is from 1 to 2147483647.

voip Key character, indicating that this interface is a network interface.

pots Key character, indicating that this interface is an often used telephone interface.

Command Mode


Usage Guideline

In a global configuration mode, use the dial-peer voice command to entera dial-peer

configuration mode, and use exit to return to the global configuration mode.

& Note:

When configuring VoIP and POTS dial-peers, different numbers should be used to identify.

Example

! The following example enters the dial-peer configuration mode to configure a POTS

dial-peer whose identification is 10.

Quidway(config)# dial-peer voice 10 pots

1.10 download

To download the codec program of specified protocol to the voice processing unit, use

the download command.

download { g723 | g729 } board-num

Syntax Description

g723 Download the G.723.1 codec protocol program to the voice interface card.

g729 Download the G.729.1 codec protocol program to the voice interface card.

board-num Serial numbers of the voice interface cards to which the program isdownloaded. The value range is from 0 to 17318.

Default

By default, select to download g729 codec protocol.

Command Mode


Usage Guideline

In the application note that the program running on the same voice interface card can

only simultaneously support G.711 and G.723.1, or G.711 and G.729, but cannotsimultaneously support G.729 and G.723.1 protocols.

As a called party, the codec protocol supported on the voice card should be in

consistency with the codec type set in the dial-peer of the POTS type that had been

established relation with the card port; and as a caller, the codec protocol on the cardshould be in consistency with codec type set in the dial-peer of the VolP type usedduring the outgoing calling from the POTS port on the card. Otherwise it will lead to

unidirectional conversation or even no conversation. When changing the codecprotocol program on the voice card, be sure to check the codec protocol setting of thedial-peer related to the port on the voice card.

Example

! The following example downloads the G.723.1 codec protocol program to the No.1

voice processing unit.

Quidway(config)# download g723 1

1.11 echo-cancel

To configure echo-cancel function parameters, use the echo-cancel command. Tocancel the echo-cancel function parameters setting, use the no form of this command.

echo-cancel { enable | coverage coverage-time }

no echo-cancel { enable | coverage }

Syntax Description

enable Indicate to enable an echo-cancel function.

coverage coverage-time Adjust the length of an echo-cancel sampling time. The

values for the coverage-time are 16, 24 and 32 in millisecond (ms).

Default

By default, the echo-cancel function is enabled and the coverage-time is 16 ms.

Command Mode


Usage Guideline

Use the echo-cancel coverage command, if the voice originated from a certain

interface is fed back within a specified time, this part of voice (echo) will be cancelled.

If a too large time value is set, the converge time of the echo canceling on the network

will become longer, so when the connection has just been established, the user mayhear the echo; and if the time value is set as too small, the user may also hear part ofthe echo, because the relatively longer echo has not been completely cancelled.

There are no echo and echo-cancel on the IP side.

& Note:

Only when being used in combination with the echo-cancel coverage command will

effect the echo-cancel enable command.

Example

! The following example sets the echo-cancel sampling time as 24 ms on voice port 1.

Quidway(config-voice-port1)# echo-cancel enable

Quidway(config-voice-port1)# echo-cancel coverage 24

Related Command

voice-port non-linear

1.12 input gain

To configure the gain value at the voice interface input end, use the input gain

command. To return to the default, use the no form of this command.

input gain value

no input gain

Syntax Description

value Voice input gain ranging from -14.0 to 14.0 in dB with one digit after the decimal

point.

Default

By default, the value is 0 dB.

Command Mode


Usage Guideline

When the voice signal on the line attenuates to a relatively great extent, this command

can be used to appropriately enhance the voice input gain.

Example

! The following example configures the voice input gain as 3dB on voice port 1.

Quidway(config-voice-port1)# input gain 3

Related Command

output attenuation non-linear voice-port

1.13 ip precedenceTo configure the IP data package priority level, use the ip precedence command. To

return to the default, use the no form of this command.

ip precedencepriority-number

no ip precedence

Syntax Description

priority-number Indicate the IP data package priority level, whose value is the integerbetween 0 and 7.


15/84




1-12

Default

By default, priority-numberis 0.

Command Mode


Usage Guideline

Specify the voice flow IP data package priority level related to this dial-peer. In the

command, when the value ofpriority-number is between 1 and 5, it indicates that the

configuration is set for the IP data flow, and values 6 and 7 are used for the update ofthe network and backbone routers. For instance, in order to ensure the voice flowrelated to the dial-peer 103 which is of the VolP type, the IP data package priority level

is defined as 5, then when an IP call is related to this dial-peer 103, the TOS field of theIP header of all the data packages transmitted to the IP network through this dial-peer

are set as 5. When the network receives these packages that have been set with arecognized priority levels, these packages will be processed before those packageswith relatively lower priority levels..

Example

! The following example configures the IP data package priority level as 5 for the VoIP

dial-peer 103.

Quidway(config-peer-voip103)# ip precedence 5

Related Command

dial-peer voice

1.14 num-exp

To define how to expand an abbreviated number into a whole number or a destination

mode, use the num-exp command. To delete the existing definition, use the no form ofthis command.

num-expextension-numberexpanded-number

no num-expextension-number

Syntax Description

extension-number Abbreviated number of the dial-peer definition, a character string

consisting of 32 digits from 0 to 9.

expanded-number Corresponding telephone number or destination mode after an

abbreviated number is expanded.

Command Mode



16/84




1-13

Usage Guideline

Use a dot . as the wild-card representing a digit. Every digit to be represented needs a

wild-card, so if three digits are required to be replaced with wild-cards in an abbreviated

number, three dots will be used.

Example

! The following example expands 2118 to 8008302118.

Quidway(config)# num-exp 2118 8008302118

! The following example expands with wild-cards.

Quidway(config)# num-exp 2... 8008302...

1.15 operation

To select a wire scheme for the E&M interface, use the operation command. To deletean existing wire selection scheme, use the no form of this command.

operation { 2-wire | 4-wire }

no operation { 2-wire | 4-wire }

Syntax Description

2-wire Indicate to select a 2-wire E&M wire scheme.

4-wire Indicate to select a 4-wire E&M wire scheme.

Default

By default, select a 4-wire E&M wire scheme.

Command Mode


Usage Guideline

When E&M is used in PBX communication, its voice uses two or four wires, plus two orfour signaling wires. So, a 4-wire E&M actually has at least six wires.

This command is used for the wire match between the voice router and remote end

equipment connected with it. It has influence on voice transmission only and has

nothing to do with signaling. If a wrong wire scheme is configured, the user will get aunidirectional voice service only.

This command is not used to the FXS and FXO interfaces, because these both are 2-

wire interfaces.

Example

! The following example sets that the E&M interface selects a 4-wire wire scheme.

1.18 prefix

To set the prefix of the telephone number dialed by the dial-peer, use the prefix

command. To delete the prefix of the telephone number dialed by the dial-peer, use theno form of this command.

prefixstring

no prefix

Syntax Description

string Prefix code. For it, digits from 0 to 9 and the comma , serving as a time delay,

and a character string within 32 characters can be selected. A comma indicates a timedelay of 500 ms, and it is up to the configuration of private branch exchange (PBX)connected by the router whether to transmit a second dial tone.

Command Mode


Usage Guideline

When a router with which a voice function is configured receives a voice call, it makes a

comparison between the number configured in the destination pattern of its own POTS

dial-peer and the number received, and selects one POTS dial-peer to continue the callprocessing.

The router will remove the string of the called number that matches the destination

pattern starting from the left. If a prefix is configured, the prefix will beadded before the


19/84




1-16

remaining number string, and the router will make a call according to the new stringgenerated.

Suppose the called number is 0102222, the 010 on the left will be deleted because of

matching with the destination-pattern. The remaining 2222 will be added with a prefix0 and will be dialed out again, that is, the number called by the router is 02222, andbetween the 0 and the first 2 there is a time delay of 500 ms.

This command is used only for the POTS dial-peer configuration.

Example

! The following example uses 0 as a prefix, and pauses for 500 ms after dialing 0 .

Quidway(config-peer-pots10)# prefix 0,

the two connected parties can hang up.

groundstart Ground start, used for FXS and FXO interfaces. If ground start is set, then

both the connected parties can initiate calls and hang up.


22/84




1-19

wink-start Wink start mode. The caller end hooks off to seize the line through line E,

and it has to wait for a wink signal from the remote end before sending out the callednumber.

immediate Immediate start mode. The caller end hooks off to seize the line through

line E and sends the called number. The prerequisite for using the immediate startmode is: The equipment at the remote end should surveil the dial signal immediatelyafter identifying the off-hook signal.

delay-dial Delay start mode. The caller end sends an off-hook signal and, after a while,

detects the called end status. If the called is in an on-hook status, the caller end willsend the called number; but if the called is in an off-hook status, then the caller will keepon waiting until the called hooks on, and the caller end will send the called number.

The last three key words are used to E&M interfaces.

Default

By default, FXS and FXO interfaces select the loopstart start mode, and E&Minterfaces select the immediate start mode.

Command Mode


Usage Guideline

The start mode used for an E&M interface should be in consistency with the PBX

connected with it.

If the E&M interface is configured with the immediate start mode, some PBXs may lose

initial digital signals. In this case, please turn to use the delay-dial start mode.

1-20

Command Mode


Usage Guideline

To set the H.323 technical prefix in the VolP dial-peer configuration mode is mainly to

facilitate the GK Server to identify the types of dial-peers. An agreement on the relatedtypes is reached beforehand between the VolP dial-peer and the GK Server, e.g.technical prefix 1# represents a voice dial-peer, prefix 2# represents a video dial-peer,

etc. When a normal communication is going on between the VolP dial-peer and the GKServer, the GK judges the dial-peer type according to the technical prefix informationreceived.

Example

! The following example configures VoIP dial-peer 101 with a technical prefix 6#.

Quidway(config-peer-voip101)# tech-prefix 6#

Related Command

1.25 timeouts

To configure dial time interval corresponding to various voice ports, use the timeouts

command. To return to the default, use the no form of this command.

timeouts { call-disconnect | initial | interdigit } seconds

no timeouts { call-disconnect | initial | interdigit }

Syntax Description

call-disconnect seconds The timeout of the howling tone sent to the caller after the

called hangs up. The value range is 0 to 120 seconds.

initial seconds The timeout from off-hook to dialing of the first number. The value

range is 0 to 120 seconds.

interdigitseconds The timeout between dials of two digit numbers. The value range is0 to 120 seconds.

Default

By default timeouts are all 10 seconds.

Command Mode


Usage Guideline

Command timeouts call-disconnect seconds is used to configure the timer that

sends a howling tone to the caller. When the called hangs up, the timer is activated. If


24/84




1-21

there is a timeout in the timer but the caller has not hung up, it will send a howling toneto the caller, urging the caller to hang up.

Command timeouts initialseconds is used to configure the timer for the system to

wait for a user to dial the first digit number. When the user starts to dial, the timer isactivated. If there is a timeout in the timer, the user will be prompted to hook on and thecall is terminated.

Command timeouts interdigitseconds is used to configure the timer for the system to

wait for a user to dial the next digit number. Every time the user dials a digit number, thetimer restarts till required digits are dialed. If there is a timeout in the timer before thedialing is finished, the user will be prompted to hang up and the call will be terminated.

Set the timeout parameterseconds as 0, and the corresponding timer will be disabled.

Example

! The following example configures the dial timeout timer on voice port 1 as 10 seconds.

Quidway(config-voice-port1)# timeouts initial 10

1.26 timing

receives in the E&M interface wink start mode. The value range is 100 3000 ms.

wink-waitmilliseconds The maximum time the caller end waits for the receiver end to

send a wink signal in the E&M interface wink start mode. The value range is 100 5000

ms.

Default

By default delay-duration milliseconds is 400 ms.


25/84




1-22

By default delay-startmilliseconds is 300 ms.

By default digitmilliseconds is 120 ms.

By default interdigitmilliseconds is 120 ms.

By default wink-durationmilliseconds is 500 ms.

By default wink-waitmilliseconds is 500 ms.

Command Mode


Usage Guideline

Command timing delay-duration milliseconds is used to set that in the E&M interface

delay start mode, when the caller end detects that the called party is still in an off-hook

status, it will not keep waiting. If the called party is still unprepared for receiving anumber when the wait time is longer than the set milliseconds , the caller end will giveup the connection request and will not wait any longer.

Command timing delay-start milliseconds is used to set that in the E&M interface

delay start mode, after sending an off-hook signal, the caller will wait for a while andthen test the called equipment status.

Command timing digit milliseconds is used to set the duration of a DTMF signal.

Command timing interdigit milliseconds is used to set the time interval betweenDTMF signals.

Command timing wink-wait milliseconds is used to set the maximum time duration the

caller end waits for a wink signal from the receiving end in the E&M interface wink startmode.

The above commands are all for the setting of the caller end equipment, so they areeffective to the caller end only.

Example

! The following example sets the maximum delay duration on port 1 as 3000 ms.

Quidway(config-voice-port1)# timing delay-duration 3000

26/84




1-23

Syntax Description

1, 2, 3 and 5 Correspond respectively to the four signal types of E&M interfaces, i.e.

type 1, 2, 3 and 5.

Default

By default the E&M interface signal type is type 5.

Command Mode


Usage Guideline

Of the E&M signaling types, a PBX transmits signals on the M line (M means Mouth,

indicating it is transmitted from a PBX), and receives signals from E line (E means Ear,indicating it is received by the PBX). So, as to a router that has voice function, the routerreceives the M signal of the PBX, and transmits E signal to the PBX.

E&M interface has four data transmission (signal) lines, and two or all the four lines areused according to different types:

E (Ear or Earth ): the signal line from the router side to the PBX side.

M ( Mouth or Magnet ): the signal line from the PBX side to the router side.

SG (Signal Ground): used for some types of E&M only.

SB (Signal Battery): used for some types of E&M only.

Example

! The following example configures voice port 1 E&M interface type as type 3.

Quidway(config-voice-port1)# type 3

1.28 vad

use the no form of this command.

vad

no vad

Default

By default the silence detection function is disabled.

Command Mode



27/84




1-24

Usage Guideline

VAD is an abbreviation of Voice Activity Detection, generally termed as silence

detection. Its basic idea is to detect and delete any silence on the basis of the difference

of energy between the voice signals of people s conversation and their silence signals,so that no signals are produced; and only when an abrupt activity tone is detected will avoice signal be generated and transmitted. It is shown by research that no less than50% transmission bandwidth can be attained by the use of VAD technology.

Example

! The following example enables the VAD function of POTS dial-peer 10.

Quidway(config-peer-pots10)# vad

29/84




1-26

shortest Indicate to perform the match according to the shortest number.

Command Mode


Usage Guideline

Command voip match-policy is used todecide if the match is performed according to

the longest or the shortest number for the number match. For instance, destination-pattern 0106688 and destination-pattern 01066880011 are respectively configured in

two dial-peers. when the user dials 01066880011, if the router is configured with theshortest number match-policy, then the router originates a connection to 0106688 atthe remote end, and the four numbers 0011 will not be processed; if the router is

configured with the longest number match-policy, and the user only dials 0106688, therouter will wait for the user to dial. After timeout, the number match-policy configuredwith the system is neglected, and the shortest number match-policy will be

automatically followed to make a call; if the user dials 0106688# (here the "#represents the dial terminator configured by the system), the router will likewise neglectthe number match-policy configured by the system and use the shortest number

match-policy, thus providing a greater flexibility for the configuration of user dialscheme.

Example

! The following example configures that the number match is performed according tothe longest number.

Quidway(config)# voip match-policy longest

Chapter 2 IP Fax Configuration Commands

IP Fax configuration commands include:

l fax level

l fax local-train

l fax protocol

l fax rate

l fax support

l fax train-mode

l fax-relay

l debug ipfax

l debug vpm

2.1 fax level

To configure the gateway carrier transmitting energy level, use the fax level command.

To return to the default, use the no form of this command.

fax level level

no fax level

Syntax Description

level Gateway carrier transmitting energy level, ranging 3 to 60.

Default

15

Command Mode


Usage Guideline

Usually the default of the gateway carrier transmitting energy level is acceptable. If fax

still can t be sent when other configurations are correct, you can try to adjust thegateway carrier transmitting energy level.

Example

! The following example configures the gateway carrier transmitting energy level as 20.

Quidway(config-peer-pots1)# fax level 20


40/84




2-2

2.2 fax local-train

To configure the fax local training threshold value, use the fax local-train command. To

return to the default, use the no form of this command.

fax local - t rain thresh oldthreshold

no fax local-train threshold

Syntax Description

threshold Local training threshold value, ranging 0 to 100.

Default

15

Command Mode


Usage Guideline

When rate training is being carried on between FAXes, the transmitting FAX transmits

the 0 TCF data at 1.5s10% to the receiving FAX, and the receiving FAX decideswhether or not the rate is acceptable according to the TCF data received.

The command is used to configure the local training threshold value if the local training

mode is configured. Error happens during the TCF transmission if 1 appears in theTCF data received. If the number of 1 received is less than the threshold valueconfigured, the transmission is successful, otherwise, it is unsuccessful.

Example

! The following example configures the fax local training threshold to 20.

Quidway(config-peer-pots1)# fax local-train threshold 20

2.3 fax protocol

To configure the number of transmitting redundant packets of T38 fax protocol, use thefax protocol command. To return to the default, use the no form of this command.

fax protocol { t38 [ ls-redundancyt38number| hs-redundancynumber] | cisco }

no fax protocol { t38 [ ls-redundancy | hs-redundancy ] | cisco }

Syntax Description

t38 Using the T38 fax protocol.

Isredundancy Configuring the number of redundant packets of low rate data,

ranging 0 to 5.


41/84




2-3

hs-redundancy Configuring the number of redundant packets of high rate data,

ranging 0 to 2.

cisco Using the fax protocol which is compatible with CISCO.

Default

The two kind of redundant packets are 0.

Command Mode


Usage Guideline

The low rate indicates the V21 command data, and the high rate indicates the TCF data

and figure data.

When connected with CISCO fax terminal, you need to choose CISCO fax protocol.

When connected with other fax terminals that support T.38 protocol, you need to

choose T.38 protocol. Because CISCO devices do not support the mode of local faxtraining, you have to adopt the mode of point-to-point training for the connection withCISCO devices.

Example

! The following example configures the number of the transmitting redundant packets of

T38 fax protocol to 20.

Quidway(config-peer-pots1)# fax protocol t38 hs-redundancy 2

2.4 fax rate

To set the highest speed enabled by the gateway, use the fax rate command.

fax rate{ 12000 | 14400 | 2400 | 4800 | 7200 | 9600 | disable | voice }

Syntax Description

If the setting is the values except disable and voice , then set the fax rates to the

corresponding values. The set rate is the highest rate enabled, instead of the only rate

specified.

If the setting is the voice mode, the highest rate enabled by the fax will be finallydecided according to the voice codec protocols.

l If the voice codec protocol uses G.711, the fax rate is 14,400bit/s.

l If the voice codec protocol uses G.723.1 Annex A, the fax rate is 4,800bit/s.

l If the voice codec protocol uses G.729, the fax rate is 7,200bit/s.

If the setting is disable , the fax function will be disabled.

Default

voice


42/84




2-4

Command Mode


Usage Guideline

The user can set the fax rate according to the voice codec protocols adopted.

Example

! The following example sets the highest fax rate enabled by the gateway to 9,600bit/s.

Quidway(config-peer-pots1)# fax rate 9600

2.5 fax support-mode

To configure the fax interworking mode with other equipment, use the fax support-

mode, command.

fax suppor t -mode{ standard | rtp | vt }

Syntax Description

standard Standard mode.

rtp RTP mode.

vt The mode when interworking with the VocalTec gateway.

Default

rtp

Command Mode


Usage Guideline

Under common conditions, use the RTP mode. When interworking with the VocalTec

gateway, the vt mode is adopted. At present, standard mode does not supportinterworking with the VocalTec gateway.

Example

! The following example configures the mode when interworking with VocalTec deviceto vt.

Quidway(config-peer-pots1)# fax support-mode vt


43/84




2-5

2.6 fax train-mode

To set the training mode used by the gateway, use the fax train-mode command.

fax t ra in -mod e{ local | ppp }

Syntax Description

local Using the local training mode.

ppp Using the point-to-point training mode.

Default

local

Command Mode


Usage Guideline

The local training mode means that the gateway participates in the rate training

between the FAXes at both ends. In this mode, first carry on the training between theFAXes and between the gateways respectively, then the receiving gateway will transmit

the training result of the receiving end to the gateway at the transmitting end. Thetransmitting gateway will decide the final packet transmission rate according to thetraining results of both ends.

The point-to-point training mode means that the gateway does not participates in the

rate training between the FAXes at both ends. In this mode, the rate training is carriedon between the FAXes at both ends, and it is transparent to the gateway.

Example

! The following exampl
