COMPARING WITH DS200

The differences of the DS200L system from the DS200system are briefly as follows :

• DS200L has a high capacity up to 32000 ports,

• The PCU200 Block fulfills the tasks of the CPU200 card,

• DS200L has the DCC Block for high capacity switching,

• The units communicate over LAN with TCP/IP protocol,

• It is necessary to install 4E1 cards on UTIL200 cards,

6

COMPARING WITH DS200

• It is possible to utilize the CC cards in main racks, instead of the CPU200 card ,

• External power block is utilized instead of the SPS200

power supply at high capacities,

• DS200L utilizes Power Inverter and Network Switch.

7

PHYSICAL CONNECTIONS

8

PHYSICAL CONNECTIONS

• The connections between EX200 Utility 4E1 Card and DCC block are provided via metal shielded one-to-one CAT5 STP cable

• The connection between PPC SS7 Card and network switch is provided via ethernet cable.

• The connection between CC Card and network switch is provided via ethernet cable

The connection between maintenance computer and network switch is provided via ethernet cable

9

PHYSICAL CONNECTIONS

• The connections between PCU200& redundant PCU200 and network switch are provided via ethernet cable

The connection between DCC block and network switch is provided via ethernet cable

• The connection between DCC block and SS7 Network is provided via metal shielded one-to-one CAT5 STP cable

10

• If SPS200 is not used, DCC, power inverters and SPS248 units are connected to the external power block.

• Maintenance computer, CC cards in TW200 towers, external power block and PCU200 units are connected to the network switch.

• PCU200 and network switch, on the other hand, are connected to the power inverters and receive the necessary voltage for their operation from the power inverters.

PHYSICAL CONNECTIONS

11

TW200 TOWER STRUCTURE

• A TW200 tower consists of 3 racks; one main rack and two auxiliary racks ( In fact, only a single main rack can also be named as a tower ).

• The rack structure of TW200 is same as a DS200 rack.

• The UTIL200 and other cards that are used in DS200 racks are also used in TW200 racks.

• Since the PCU Block functions as the main processor in the DS200L system, no CPU200 card is available. The CC card is employed instead of the CPU200 card.

12

NOTE: No redundant CC is used in the TW200 towers. Since the PCU200 block fulfills the tasks of CPU, redundancy of the PCU200 block is available in the DS200L exchange.

CC MODULE

13

CC Module has :

● 1 Ethernet port

● 32 MByte Flash Memory

● 256 MByte RAM

● Linux operating system

The main function of the CC card is : to provide

communication between the PCU200 block and the racks.

CC MODULE

UTILITY 4E1 CARD

15

UTILITY 4E1 CARD

16

• The Utility 4E1 card is mounted on to the UTIL200 card.

• 4 E1 ports are available on the card.

• Each E1 port has 31 speech channels.

UTILITY 4E1 CARD

17

• Via this card, at most 12*31 = 372 speech channels are supplied for one tower.

• The connections within a tower do not require a speech channel for 4E1 card, instead directly connected by UTIL200 card.

• Since there are 3 racks in a tower (TW200), at least 1, at most 12 E1 connections can be made per tower.

UTILITY 4E1 CARD

18

• The E1 ports that are on the Utility 4E1 cards are connected directly to the DCC 8E1 Interface cards that are in the DCC Block.

• Speech channels between the TW200 towers and the DCC block are connected through the E1 channels of the towers.

PCU200 BLOCK

20

INFORMATION

• PCU200 ( PC Unit ) is a processor that has been based on a 19” PC which controls all functions of the exchange.

• The PC that functions as the PCU200 is 19” in width, 2U in height and 80 cm in depth. It is placed in a 19” cabinet.

• The master software of the exchange runs under the Linux Suse 11.0 O/S on the PCU200 computer .

21

INFORMATION

The minimum requirements of a DS200LPCU200 block :

• Pentium IV 2.4 GHz. processor• 60 GB hard disk• 1 GB RAM

22

PCU200

• The master software runs under LINUX in real time and performs its functions by means of a file system.

• Using this file system, the entire exchange parameters, statistical data, call records, alarm information, etc. are stored in separate files on hard disk.

23

COMMUNICATION

• PCU200 communicates with the other units within the exchange over the TCP/IP protocol.

• PCU200 initiates intra-exchange communication.

• PCU200 controls all the communications between all the exchange units .

• The communication information, namely IP addresses and TPC ports of the DCC and TW200 units are entered in a table in the PCU200.

24

• Thanks to that structure, both of the blocks that carry out TDM and IP switching can be controlled by the same center.

• Besides, PCU200, which provides communication through the Ethernet structure, has completely been isolated from exterior factors.

• That fact is extremely essential considering that the system security is thus increased.

COMMUNICATION

25

REDUNDANCY

• It is possible to back up the PCU200 block upon wish, with another PC that is a one-to-one copy of it.

• The redundant and functional PCU200 blocks are in connection with each-other through Ethernet ports.

• In case of any malfunction that occurs in the functional PCU200 block, the redundant PCU200 directly becomes functional.

26

STRUCTURE OF PCU200

• User computers that are on the same LAN provides access to PCU200. By this way, while it is possible to access all information on PCU200, raw data within the exchange is protected.

• As a result of all those protection measures, the exchange security has been maximized.

27

• A special partition has been created on the hard disk of the PCU200 computer. There is a directory, namely karel, under that partition.

• Parts of software and the files created by the exchange during run-time are placed in a subfolder which is under that directory and which is compatible with the exchange software.

For example: karel/bin/ zr_new_23.rpm

SOFTWARE STRUCTURE

28

SOFTWARE STRUCTURE

29

• The directory structure given above is supposed to be created by the user on the maintenance PC that is utilized for programming purposes.

• Since the same directory structure exists on the Linux PC (PCU200), that operation is also necessary to check and copy the specified files.

SOFTWARE STRUCTURE

30

► There are 3 directories under the directory karel, these are sbin, bin and home.

There are 6 files in the folder sbin.

1) dsinit: This file specifies the master software that is to run in the system.

2) check: This file allows the read-write-execute permissions of the files to be set.

3) dslog: This file allows the system logs to be displayed.

SOFTWARE STRUCTURE

31

4) stop: This file allows the system to be stopped.

5) start: This file allows the system to be started up.

6) arpsave: IP and MAC addresses of CC cards in TW200 towers are stored in this file.

SOFTWARE STRUCTURE

32

● The master software of the exchange exists in the directory bin.

● The software runs at the level defined as “Run level 3” of the Linux operating system.

● There is a main task program at the Linux operating level, which controls the operations of the entire exchange software. This program controls the operations of other sub-tasks and in case of a malfunction, it automatically ensures that the malfunction is eliminated. That main program is the master software of the exchange. The sub-task files with the extensions "so" and "rt" exist in this master software

DIRECTORY BIN

33

• There are 5 directories in the directory home. These are : log, cm, conf, data and alarm directories.

1) log: Log files for analyzing ( for maintenance) the entireoperations in the system, which are created during theoperation of the exchange are kept in this directory.ds_gg_aa_yyyy.log is a file which saves the log informationaccording to date. For example, the system is operating for 2days and the date of first started of the exchange is22.08.2009, then the files named ds_2009_08_22.log andds_2009_08_23.log are automatically formed under the logdirectory. Thanks to this, errors can be analyzed day by day.

DIRECTORY HOME

34

• nks_err.log and nks.log files are the logs belonging to NetConsole Server. Besides these, there are 2 files named sip_spc_curr.log, and sip_spc_prev.log related to SIP ProxyServer under the log directory.

• sip_spc_curr.log file saves the current ( active )operations of SIP Proxy Server. sip_spc_prev.log file saves the previous operations of SIP Proxy Server.

*** %40 of the karel directory can be used for logs.

NOTE : NetConsole Server is embedded and automaticallyruns on the PCU200 computer.

DIRECTORY HOME

35

2) cm: The files cm00.bin, cm01.bin,.......... cm15.bin,which contains the call record information of the exchangeare kept in this directory.

• Size of each file is 16 MB

• 7.250.000 call records in total are stored in the exchange memory.

DIRECTORY HOME

36

3) conf: There are 4 files under this directory ;pbxcomm.conf, dsinit.conf, snmp.conf and sip_spc.conf .

*** Two text files pbxcomm.conf and dsinit.conf aresupposed to be created manually before installation ofthe exchange starts.

DIRECTORY HOME

37

• pbxcomm.conf is the file that specifies the IP addresses, orders and TCP Port numbers of TW200 towers and DCC block.

• Explanations of pbxcomm.conf are written inside the file.In this file, there is a template which shows how to enter thedata into this file.

PBXCOMM.CONF

38

• The user will make the definitions in the part which is under the template of the file.

• The command that is to be used in the text file is “ connect ”. Some of the parameters, which are to be used afterwards are given in the following pages.

3 of TW200 towers, a DCC block, a virtual tower and an PPC SS7Card have been defined in the file pbxcomm.conf, which has beenstated above as an example.

PBXCOMM.CONF

41

• The IP addresses and port numbers to be entered in that file completely depend on the requirements of the installation location. On the other hand, since the DS200L IP system is completely isolated from external networks, desired IP numbers can be used in the table.

• Order of the defined TW200 towers is from the top to the bottom, i.e., the tower at the top with the IP address 192.168.2.1 is the first tower, the tower in the second line is the second tower and so on. The line defining a new tower must precede the line in which the DCC block is defined.

PBXCOMM.CONF

42

• The file dsinit.conf specifies the master software to run on the system .

• The main exchange software existing in the dsinit.conf file can be automatically set by the command check z_xxx which is entered from the SSH Secure Shell Program. So , there is no need for the user to enter this information into the dsinit.conf file manually. But the version information needs to be checked in the dsinit.conf file. And if redundant PCU200 is running in the system, “buddy= x2” definition should be made

into the dsinit.conf file.

DSINIT.CONF

43

● buddy= X2 [ This definition is necessary for operation of X2 computer(redundant PCU200 ) ]

● VERSION = z_new_68 [ line specifies the master software to run on thesystem].

DSINIT.CONF

44

• This file is formed for SNMP ( Simple Network Management Protocol ) applications.

• Normally, there is no need to make a definition into this file. In this case SNMP connection can be provided from any IP address.

• If preferred, IP definiton can be made by entering an IP address after “=” into the “TrapTargets” field. For this case, SNMP connection can be done only from the device which has this IP address.

SNMP.CONF

45

For example;

TrapTargets= 192.168.179.122 ,192.168.179.101

• When this definition is entered, this means SNMPconnection can be made only from the devices which hasthe IP address 192.168.179.122 and 192.168.179.101

SNMP.CONF

46

SNMP.CONF

47

• DS200L system also has an IP extension support. IP

extensions can be defined on the system. There is an

embedded SIP Proxy Server in the DS200L system’s

master software. The configuration file for this proxy is

sip_spc.conf .

• At the beginning, there is no need to make a definition in

this file. In sip_spc.conf file , there is a template (explanation

part ). If needed, the definitions will be made below the

template part.

SIP_SPC.CONF

48

SIP_SPC.CONF

49

• 213.139.195.162 IP address definition as NAT IP address in the part under the template above is done for the internet connection.

SIP_SPC.CONF

50

4) Data: The files pertaining to the entire programmed parameters in the exchange are stored in this directory.

SOFTWARE STRUCTURE

51

5) Alarm: The files alarm00.bin and alarm01.bin, which contain alarm information of the exchange are stored in this directory.

SOFTWARE STRUCTURE

52

A DCC block consists of the units below:

• DCC Chassis• DCC Backplane• DCC Utility Card• DCC 8E1 Interface Card• DCC Power In Card

DIGITAL CROSS CONNECT

53

• The DCC Block is the switching matrix that fulfills the main switching function for the exchange.

• DCC Block has a structre that includes the main switching controller card ( DCC Utility), 14 8E1 Interface card slots and a power regulation card (DCC Power In).

• Due to its standard 19” structure, it is placed in the same 19” cabinet with the main processor PCU200.

DCC BLOCK

54

• The DCC chassis is a 19”, 6U-high box, which has been formed of an aluminum cage structure and which mechanically places the entire cards in contact.

• It has slots for 17 cards inside, which is composed of plastic rails that are at the top and bottom of the slot.

DCC CHASSIS

55

• Communication of the entire electronic units in the DCC block is made over the DCC backplane.

• The DCC backplane transfers all signals used by DCC cards to pertinent card slots and it distributes the power coming from the DCC Power In card to all card slots.

DCC BACKPLANE

56

• The DCC backplane is the card that forms the electronic skeleton of the DCC Block.

• There are 2 special slots for the DCC Utility card and one special slot for the DCC Power In card on the backplane, as well as 14 slots for DCC 8E1 Interface cards.

DCC BACKPLANE

57

DCC POWER IN CARD

• The DCC Power In card regulates the -48 VDC feed voltage it receives from the power block of the DS200L system and transfers it to the backplane.

• The Power Control Card controls the -48 VDC voltage

fed to the DCC unit and minimizes surges in voltage with fuses and regulators on it.

58

DCC POWER IN CARD

• The card also generates the reference signal for the backplane, which is 1.5 VDC.

• Each DCC unit has minimum one Power In card. The card definitely must not be removed from its slot while the system is ON.

59

• The DCC Power In card is plugged in the rightmost slot. If redundant of this card is available, redundant card should be installed into the leftside ( slot number 0 ) of the DCC Power In card. Normally, this slot is used for DCC 8E1 INTERFACE cards.

• When redundant DCC Power In card is installed, number of DCC 8E1 INTERFACE cards to be installed is decreased by 1 and is equal to 13.

• When redundant DCC Power In card is installed into the

system, system will go on operating without any problem in case any problem occurs at master DCC Power In Card.

DCC POWER IN CARD

60

● The LEDs signifying +3V3 and+1V5 statuses are supposed tobe continuously ON state duringthe normal operation of the system, whereas all the otherLEDs are supposed to be ON.

● In case the LED statuses aredifferent from what have beenspecified here, the system shouldbe checked.

DCC POWER IN CARD

61

• The DCC Utility card is the main unit, which controls the entire DCC functions and which includes the switching matrix.

• The DCC Utility card consists of the Utility motherboard and the PPC CPU card, which has been attached to the motherboard with two connectors that are on the

motherboard.

• The main processor of the DCC Utility card is the Power PC CPU card.

DCC UTIL CARD

62

• A single UTIL card suffices for DCC operation. However, a redundant one may be made available when needed, i.e., two UTIL cards can be installed in the DCC block.

• Both cards are identical in hardware. In case of a malfunction in the functional DCC UTILITY card, the DCC automatically shifts to the redundant UTIL card. During that transition, no system pause or data loss occurs.

DCC UTIL CARD

63

• The DCC UTILITY card and the redundant DCC UTILITY card( if available ) are supposed to be installed in the slots in the middle, which are labeled CP1 and CP2 on the DCC backplane. Master DCC UTILITY card is installed into the CP1 slot and redundantr DCC UTILITY card is installed into the CP2 slot.

• An RS232 input, a 100 Mbit Ethernet input, a 10 MB Ethernet input and some LEDs are available on the DCC UTILITY card. Those LEDs will be explained later in the document.

DCC UTIL CARD

64

DCC UTIL CARD

65

The LEDs on the DCC Utility card and their functions havebeen explained below:

POWER: This LED is supposed to be continuously ON. Ifit flashes, then the DCC block must be turned OFF andthen back on after 15 seconds. DSP-A, DSP-B, DSP-C, DSP-D: These LEDs signify thatthe DSP unit is operational. They are supposed to beblinking.

DCC UTIL CARD

66

10 RX, 10 TX, 100RX, 100TX: These are supposed to beflashing during data transmission or reception over localarea network (LAN).

CPU: It is supposed to blink periodically.

M/S (Master/Slave): This LED is supposed to be continuouslyON, if the master DCC Utility card is functional in the DCCBlock.

DCC UTIL CARD

67

LOCK: This LED is supposed to be blinking periodically,if DCC is using external clock. If it does not blinkperiodically, then that signifies there is a problem with theexternal clock signal.

HOLD: This LED is supposed to be continuously ON, ifDCC is using its own clock signal.

10 BASE-T, 100 BASE-T: If the upper green LED is ONafter an ethernet cable has been attached, then thatsignifies the connection has been established. On the otherhand, the red LED signifies a problem with the cable or theconnection.

DCC UTIL CARD

68

DCC 8E1 CARD

69

• The DCC 8E1 Interface card has 8 E1 ports, as its name already indicates and it can be installed in the 14 general purpose slots within DCC.

• 8E1 cards have been numbered starting with the rightmost slot in the DCC Block. The rightmost slot ( leftside slot of the DCC Power In Card ) has been reserved for the 8E1 card number 0, and the leftmost one for the 8E1 card number 13 in the DCC block.

DCC 8E1 CARD

70

• The DCC 8E1 Interface card receives the 48 VDC feed voltage from the backplane and generates the 3.3 VDC signal it needs. By this way, the power signals within the DCC block have been isolated from each other, so that defective units are prevented from adversely affecting other units.

DCC 8E1 CARD

71

• The DCC 8E1 Interface card has embedded self-test feature.

• The DCC 8E1 Interface card is capable of applying BERT to the E1 channels within DCC. By this way, any problem that might occur in the future is easily detected in advance and necessary precautions are taken before system performance deteriorates.

DCC 8E1 CARD

72

• The DCC E1 lines constitute the main frame for voice transmission system of the exchange. Those lines can be used to provide transmission paths for speech channels between DCC and TW200 towers.

• The E1 lines extending to TW200 towers are connected to the Utility 4E1 cards that are in the towers.

DCC 8E1 CARD

73

• Each E1 line provides 31 speech channels to a tower. It is sufficient to increase number of E1 connections to towers in order to increase number of speech channels.

• In case several E1 channels are connected to the TW200 4E1 card, distribution of speech channels to those E1 lines is arranged by the system automatically.

DCC 8E1 CARD

74

SWITCHING ON DCC

• Intra-rack and inter-rack switching in the DS200L system is conducted over the UTIL200 card, whereas inter-tower switching ( switching between towers ) are conducted over DCC.

• The DCC block has a 4096 x 4096 switching matrix. By

this way, 8192 channels in the DS200L exchange can be simultaneously used for conversations.

• The switching matrix on the DCC block is distributed to the TW200 towers over E1 lines in DCC. Thanks to the isolated E1 structure, trouble-free connections can be established even with the distant TW200 towers.

75

• Due to its structure, DCC is continuously in communication with both the TW200 towers and the PCU block. It communicates with the towers over E1 connection, whereas it communicates with the PCU Block over TCP/IP.

• Number of 8E1 cards to be installed depends on the capacity of the exchange to be used.

• At most 14 DCC 8E1 Interface cards can be installed in the DCC block. By this way, the capacity may vary between 8 and 112 E1 lines.

SWITCHING ON DCC

76

• If the capacity provided by only a single DCC is not enough, then it may be expanded by including a second DCC in the system, so that both the switching capacity is increased from 4096 x 4096 to 8192 x 8192, and number of E1 lines is increased up to 224.

• 1 to 12 E1 lines can be connected to each tower, depending on capacity requirements (Each E1 has 31 channels).

*** By this way, it is possible to provide 31 to 372 speechchannels for 672 extensions.

SWITCHING ON DCC

77

NOTE: IP addresses of the devices specified above must be so adjusted that they are in the same local area network.

NETWORK SWITCH

78

NETWORK SWITCH

• Its function is to provide the TCP/IP switching of the system blocks and to coordinate the IP communication.

• Communication and information exchange in the DS200L systems are carried over the IP network.

• The network switch is located in the 19” cabinet.

• Using a programmable network switch (which has port mirroring feature) will be useful for managing the network.

79

The Ethernet cables that are supposed to be connected tothe switch are as follows:

• The Ethernet cables coming from the CC cards in TW200 towers ,

• The Ethernet cables coming from the PCU200 Block and the redundant PCU200 Block ,

• The Ethernet cable of the maintenance computer,• The Ethernet cable of the PPC SS7 Card,• The Ethernet cable coming from the DCC Block ,• The Ethernet cable coming from the Power Supply ( if exists)

NETWORK SWITCH

80

EXTERNAL POWER BLOCK

• In case of large capacity DS200L systems require high capacity battery groups, External power supplies can be used instead of SPS200 power supplies.

• For proper power regime, in addition to external power supplies the capacities of the batteries must be selected appropriately for the system capacity.

• External Power Block feeds DCC block, power inverter and the SPS248 power supplies which are at the TW200 towers by -48V. Cabling is to be made from External power supply to each tower and to other units.

81

POWER INVERTER

Power Inverter and redundant one for DS200L system

82

• For small capacity systems, in case system is fed by SPS200 power supplies, PCU Block and network switch can get the required 220V AC voltage from the electricity network. In this case, there will be no need for power inverter.

• For large capacity systems, system gets -48V voltage from the External power supply , -48V coming from External power block is converted to 220V AC and transmitted to PCU200 block, redundant PCU200 block and network switch.

POWER INVERTER

83

• Power Inverters are located in the 19” cabinet. Optionally, redundant power inverter can be installed to the system.

• At the systems which has redundant power inverter, in case any problem with any of the power inverter occurs, the redundant power inverter is put into operation. Thus, PCU200 blocks and network switch get the 220V AC input from the redundant one and keep operating without any problem.

POWER INVERTER

84

When installing the DS200L system, after the physicalconnections have been made, the instructions below

should be followed in the specified order.

INSTALLATION

85

1) Power ON the towers in the system, turn ON the maintenance PC.

2) Define separate IP addresses for each CC card in every TW200 tower.

3) Define IP address for the PPC SS7 Card.

4) Power ON the DCC block.

5) Define the IP address for the DCC block. That is done through the serial port over the HyperTerminal connection.

INSTALLATION

86

6) Reboot the DCC block (Turn it OFF and then back ON.) After the DCC block has been turned ON, enter the command “ping” in the MSDOS command line of the maintenance computer in order to check whether the DCC block is accessible or not.

Example: Type “ping 192.168.2.100” in the MSDOS command

line and press the ENTER key. If a reply comes from the IP address 192.168.2.100, then that indicates the address is reachable.

INSTALLATION

87

7) Note down the IP and MAC addresses of the CC cards ( towers ) and the DCC Utility Card on a paper.

8) Power ON the power inverter with the power block. By this way, the PCU200 block and the network switch, too, are fed with 220 V. Turn ON the PCU200 block by pressing the POWER button. If SPS200 is used instead of external power block, required 220V AC for PCU200 block and network switch can be supplied from UPS or from the electricity network. In this case, there will be no need for power inverter but the whole system will be open to external damaging effects.

INSTALLATION

88

9) Reach the factory default IP address of the PCU200 block by the ping command through the maintenance computer.That address can be changed via SSH Secure Shell program .

10) Run the program WinSCP on the maintenance computer. Thanks to this program, the Linux directory structure that has been created on the maintenance computer is copied to the PCU200 computer. After copying has been complete, conduct the following operations in WinSCP, one by one.

INSTALLATION

89

11) Access the file pbxcomm.conf in a similar manner as well, in order to edit it. Type the IP addresses of TW200 towers and the DCC Block as following the order explained in the previous chapters.

12) Right-click the file dsinit.conf and select “Edit”. When the file opens, check the name of the software that is to run in the system. Definitions can be made as explained in the previous chapters.

INSTALLATION

90

13) Run the program SSH Secure Shell to set the read-write-execute (r-w-x) permissions of the entire files in the karel folder by entering the command “check z_xxx ” in the command line of cd/ karel/sbin. By the help of this command, the master software version of the system is automatically written into the dsinit.conf.

INSTALLATION

91

Follow the instructions below to commission the systemafter installation has been completed:

1. Power on the entire system with the Power Block.

2. Turn on the PCU200 block by pressing the POWER button.
