and installation considerations.

Warning：Damage of equipment or personal injure

Starting the installation without knowing the Safety Guidelines can result

in damage of equipment or personal injure.Before beginning the installation procedure, you must read the SafetyNotifications in the document: Media Gateway Safety Guidelines and

Agency Approvals". This document provides mandatory pre-installation

and installation information.

Do not continue until you have read the entire Safety Notification.

Edition 02 of 49




1.2.1 Safety Precaution

The Media Gateway has a solid chassis and sturdy modules to ensure a high degree of durability.Even so, you must take care when unpacking and installing the Media Gateway system. Rough

handling can damage some of the internal components.

The electronic components in the Media Gateway system can be damaged by Electro-Static

Discharge (ESD). ESD occurs when you do not properly ground yourself before touchingelectronic components. Because some components carry minute electrical currents, they can

become damaged by the amount of current conducted by the human body.

To guard against ESD, attach an ESD wrist strap with a 1 MΩ resistor to the ground post (or plug,

also known as the 'banana jack') on the lower left of the Media Gateway front panel.

Danger : Electro Static Discharge

If you do not wear an Electro-Static-Discharge (ESD) protective wrist

strap this can result in serious personal injure and/or damage to thechassis.

Wear an ESD protective wrist strap having a 1 MΩ resistor when you

install the chassis to the facility power, and every time you perform a

hot-swap. The banana jack is not insulated, so make sure to wear the ESDstrap, even with the grounding post secured on the chassis. Insert the wrist

strap into the banana jack on the front of the chassis at the lower left

corner. The protective strap is not included with the chassis. You canpurchase one at a local electronics supply store. See figure 2 to see where

to insert the strap.

Figure 2 ESD Wriststrap Insertion into the Chassis

1.2.2 Safe Work Areas

If you need to remove or hot swap the Media Gateway hardware, follow these precautions: Make sure the work area is clean and free of moisture

Use an ESD safe work area

Edition 02 of 49




Always wear an anti-static wrist strap with a 1 MΩ resistor to protect against ESD or

personal injure

Do not use screwdrivers or other sharp or pointed instruments when removing or installinghardware, unless otherwise instructed

Lay modules flat when they are not in the Media Gateway, or store them in a static-free bag

Make sure that the Media Gateways have a vertical offset if they are being installed inside-by-side racks.

By installing the Media Gateways with the recommended vertical offset, you ensure that sufficientambient air exists to cool the warm components. The shelf fans then exhaust the warm air. The

offset also ensures that intake fans of another Media Gateway do not draw in the warm and exhaustair from shelves in a neighboring rack.

2.1 Understanding the Media Gateway

The Media Gateway works in the data layer, accepting call data from the Public Switched

Telephone Network (PSTN) or an access switch. Simultaneously, the control and signaling data are

sent from PSTN or access switch to the softswitch. The softswitch acts as the Media GatewayController (MGC). It provides the control, signaling and routing functions, so that the entire

bandwidth of the Media Gateway is free to carry voice traffic. Figure 5 illustrates the Media

Gateway in a typical network.

Figure 5 Role of the Media Gateway in a Network

Edition 02 of 49




2.2 Understanding Megaco / 7515 Terminology

The softswitch acts as the MGC. The MGC communicates with the Media Gateway using the

H.248/Megaco protocol. The Megaco protocol and terminology used within this chapter are

explained in detail in RFC3015 document and its corrections. Below is a brief description of thebasic Megaco concepts.

Media Gateway A media gateway converts media given in one type of network to the

format required by another type of network.

Physical Termination A physical termination represents a physical entity and has a

semi-permanent existence. A Time Division Multiplex (TDM) channel

configured in a gateway is an example of a physical termination. Ephemeral Termination An ephemeral termination is a temporary entity created by means of an

Add command sent from the MGC to the media gateway.

Context A context is an association between two or more terminations.

Associating a TDM channel from PSTN with a Real-time Transport

Protocol (RTP) packet stream creates a context.

Figure 6 illustrates these basic concepts.

2.4.3 Providing IP Interfaces

Each Media Gateway requires one IP address to communicate with MGC along the control path.Following a message exchange along the control path between the Media Gateway and the MGC,

communication between two Media Gateways occurs along the voice path. Each Media Gateway

Edition 02 of 49




also requires one IP address to send and receive data along the voice path. Figure 8 illustrates theuse of IP addresses of the voice and control paths.

Figure 8 IP Addresses Used by the Media Gateway

The following procedure describes how to provide IP interfaces on the Media Gateway.

Note : 1. CTRL port can connect to 10/100M switch, 10M hub, 100Mhub, 10/100M switch is

recommended. DATA port can only connect to 10/100M switch, Full duplex, autonegotiation.

2. CTRL and DATA port ipaddress can not be in same subnet, it can be in defferent subnets, in

defferent VLANs, or one public ip address for voice path and one private ip address for signal

path.

Procedure Perform the following steps to provide the IP interfaces for the control and voice path.

1. Create an IP interface on an Ethernet port by issuing the following command

create ip if {<port> | Rpl | Port-Group | loopback} <ipaddress> <mask>

2. Enable the IP interface by issuing the following command:

define ip if state <ipaddress> enable

3. Repeat Step 1 and Step 2 until you have provided the Ethernet interfaces you will need for

your network configuration.

Edition 02 of 49




Repeat Step 1 and Step 2 until you have provided the Ethernet interfaces you will need for your network configuration. At least two IP is needed, one is for OAM and MGC and another is for

voice data. The OAM port is en.1.1(2).1 and the voice port is en.1.1(2).2

Example

My-Chassis:ACT-FSB:1.1(r0)>=47:diag:main# create ip if en.1.1.1 10.10.0.11255.255.255.0

My-Chassis:ACT-FSB:1.1(r0)>=48:diag:main# define ip if state 10.10.0.11 enable

My-Chassis:ACT-FSB:1.1(r0)>=49:diag:main# create ip if en.1.1.2 10.11.12.21

255.255.255.0

My-Chassis:ACT-FSB:1.1(r0)>=50:diag:main# define ip if state 10.11.12.21 enable

To create an IP interface on the second Ethernet port, specify port number en.1.1.2. Note that the

increment takes place in the port position of the address.

Viewing IP Interface

To view the IP interface, issue the following command:

view ip if

Example My-Chassis:ACT-FSB:1.1(r0)>=47:diag:main# view ip if

and prepare the Media Gateway to send packets along the voice path.

The following procedure describes how to provision the Media Gateway and MGC parameters.

Procedure

Perform the following steps to prepare the Media Gateway and MGC parameters.

Edition 02 of 49




Note Before setting the Media Gateway and MGC parameters, you should disable the

Media Gateway at first.

1. Define the IP address of the Media Gateway by issuing the following command:

define mgw mg ipaddress <ip-address>

Enter the IP address the Media Gateway used to communicate with the MGC.

2. Define the IP address of the Media Gateway used to pass traffic along the voice path byissuing the following command:

define ip voice address <ip-address>

3. Set the User Datagram Protocol (UDP) / Transport Control Protocol (TCP) port of the MGC

by issuing the following command (the default port value is 5000):

define mgw mg port <udp/tcp-port>

4. Set the at most once timer of the Media Gateway by issuing the following command (thedefault value for Megaco is 30 seconds):

define mgw mg atmost-timer <msec>

5. Set the initial response timer of the Media Gateway by issuing the following command (the

default value for Megaco is 5 seconds):

define mgw mg init-timer <msec>

6. Set the provisional response timer of the Media Gateway by issuing the following command(the default value for Megaco is 30 seconds):

define mgw mg prov-timer <msec>

7. Set the IP address of the primary MGC by issuing the following command:

define mgw mgc ipaddress primary <ip-address>

8. Optionally, set the IP address of the secondary MGC by issuing the following command:

define mgw mgc ipaddress secondary <ip-address>

9. Set the UDP/TCP port of the primary MGC by issuing the following command:

define mgw mgc port primary < udp/tcp-port >

Note The default port value for Megaco is 2944.

10. Optionally, set the UDP/TCP port of the secondary MGC by issuing the following command:

define mgw mgc port secondary < udp/tcp-port >

11. Optionally, set the UDP/TCP port of the secondary MGC by issuing the following command:

define mgw mg mid <mid-string>

12. You can change the parameters on the primary MGC by issuing the following command:

define mgw mgc mid primary <mid-string>

Edition 02 of 49




13. You can change the parameters on the secondary MGC by issuing the following command:

define mgw mgc mid secondary <mid-string>

14. Enable the Media Gateway by issuing the following command:

2.4.10 One Step Software System Upgrade

A7515 supports the online software upgrade, i.e., user can upgrade system software when

system is running, and the new version of software will be used when the board reboots. All thesoftware of system will be saved on the flash disk after them upgraded.

The one-step software upgrade procedure automates the upgrade process by exploding the new

PAK file and extracting the new runtime and BPF text file. The automatic upgrade halts if itencounters an error (for example, if the PAK file does not exist). If the upgrade does halt, you will

need to determine what caused the error.Check the system Syslog messages for any informationabout error conditions.

UI command:

Upgrade system {non-hitless| hitless} <pak-file>

Arguments Non-hitless is for un-redundancy upgrade, hitless is for redundancy upgrade.<pak-file> is the name of the PAK file. It can be on the remote server like

“172.24.200.21:newpak.pak” or on the local flash disk like “newpak.pak”.

You can copy file from a TFTP server to A7515 flash by issuing the following command

tftp get <rmt-file> [<lcl-file>] You can copy file from A7515 flash to TFTP server

tftp put <rmt-file> [<lcl-file>]

Arguments <rmt-file>: file name on a remote server

<lcl-file>: file name on the Media Gateway

Example My-Chassis:ACT-FSB:1.1(r0)>=3:diag:main# upgrade system non-hitlessnew0821.pak

2.6 Synchronize both FSBs

For redundant FSB configuration chassis, the both FSBs need to be synchronized. Connect two

serial cables on the RTMs’ Craft port. Reboot FSB respectively by command “reboot self”.

When the board is booting, press any key to stop it, input “9”, then “Enter”, input “2”, then“Enter”.

Example Press any key to stop auto-boot...

3

[VxWorks Boot]: 9

[VxWorks Boot]: 2

BPF: using bpf file, pf1:bpf.aat

use this vxworks:pf1:vxworks.bcLoading file pf1:vxworks.bc ...

Follow the same steps on both FSBs, then check the synchronization status:

vi ch
