Relative ConceptsRelative Concepts

TID TID is termination ID. For 2G system, VMGW use TID to indicate one E1 time slot. TID is time slot re

source of MGW. MSOFTX3000 control TDM resource in MGW depend on TID. The TID of MGW and the CIC of BSC can correspond to the sa

me physical circuit. It has corresponding relationship with actual circuit time slot, the amount of TID is equal to the number of time slot on all TDM interface boards.

To be brief, TID is one 64K A interface circuit. In one VMGW, the number is unique.

CIC CIC (circuit identification code) is a indictor of one E1 time slot, MSOFTX3000 and BSC assign circuits through CIC. It has corresponding relationship with TID.CIC is one 64K A interface circuit, for one office direction the CIC is unique and must be same with that opposite office.

Configuring Signaling Link Interworking with BSCConfiguring Signaling Link Interworking with BSC

In signaling configuration interwoking with BSC, we need to configure:

MTP destination signaling point, MTP link set, MTP route, MTP link

SCCP destination signaling point, SCCP subsystem

16 Internal Use


Add MTP destination signaling point:

Command : ADD N7DSP

For 2G network, only No. 0 record in the OFI table is valid. That is, NI

and OPC must be defined in No.0 record in the OFI table.

It is used to set whether the DSP provides STP function.

It is used to indicate whether a DSP is a associated SP of the local

office. For BSC, set it to “TRUE”.

17 Internal Use


Add MTP link set:

Command : ADD N7LKS

Adjacent DSP Index: It refers to the index of a DSP to which a link set

belongs. Here it is the DSP index of the peer BSC It must be defined i

n the command ADD N7DSP first and then referenced here.

18 Internal Use


Add MTP route:

Command : ADD N7RT

It sets the link set which used to reach a signaling point.

Link set index and DSP index must have been defined in ADD

N7LKS and ADD N7DSP.

19 Internal Use


Add MTP link:

Command : ADD N7LNK

Module Number: It is the Module No. of WCSU or WSGU board.

Start Circuit Number: It specifies the number of the E1 timeslot seize

d by an MTP link. It is valid only when the MTP link is born over TDM.

LinkSet Index: It is used to set the link set to which a link belongs.

It is a parameter for the MSOFTX3000 to interconnect with the peer e

nd, specifying the logical number of an MTP link in its MTP link set. It

should be consistent with that of the peer end.

If a timeslot in E1 used for MTP link, the “Link type” must be set TDM

64K link.

20 Internal Use


Add SCCP destination signaling point

Command : ADD SCCPDSP

One SCCP DSP record is uniquely identified by NI, OPC and DPC. It

is required that the OPC and DPC must be consistent with those of

the lower layer (MTP3) when SCCP DSP is configured.

21 Internal Use


Add SCCP subsystem number

Command : ADD SCCPSSN

SCCP Subsystem number (SSN) is the local addressing information

used by SCCP to identify the SCCP users under a SP. The configure

d SSN in A interface includes BSSA(local end &remote end) and SC

CP Management (SCMG)(remote end)

Configuring Speech Circuit Interworking with BSCConfiguring Speech Circuit Interworking with BSC

Configuring speech circuit interworking with BSC includes:

Configuring call source

Configuring office direction

Configuring BSC

Configuring LAI and CGI

MGW related configuration

A interface circuit pool, A interface trunk group, A interface trunk circuit

24 Internal Use


Add call source

Command : ADD CALLSRC

Call source Code is used to identified different call source.

Route selection source code, is related to call source. RSSC is

concerned with selecting route number, so same called prefix from

different call source can choose different route number .

25 Internal Use


Add office direction:

Command : ADD OFC

It is allocated uniquely in the system and used to identify an office

direction.

Peer office lever: It specifies the level of the peer office, High (upstream

office), Same (office of the same level), or Low (downstream office). Set

it according to the actual situation. The level of BSC is lower than the

MSOFTX3000 in the network. Here select " Low (Inferior)".

[DPC1]–[DPC16]: For these parameters, enter the DPCs of BSC. They

must be negotiated with BSC for consistency, and they are associated

with the DPCs of BSC in the ADD SCCPDSP command.

26 Internal Use


Add BSC:

Command : ADD BSC

NI and DPC used to identify uniquely a BSC

[Home Module No.1]–[Home Module No.10] : It refers to the module

number of the WCCU or WCSU controlling BSC. Note that we do not

mean to specify the processing module of the BSC, but to define the

maintenance module of the BSC.

Route Select Source Code : The route selection source code is the

category No. of outgoing route selection strategy of different call

sources. It has been defined in the ADD CALLSRC command.

BTS number define the number of BTS belonged to this BSC

27 Internal Use


Add LAI and CGI

Command : ADD LAIGCI

Global Cell ID is identifying the LA or cell. The type of the parameter (LAI o

r GCI) can be identified by the successive Location Area Type segment. E.

212 coding scheme.

MSC number and VLR number have been defined in SET INOFFMSC co

mmand.

LA Category: When the current record is a location area, set it to "LAI"; if t

he current record is a cell, set it to "GCI".

LA Type :It is used to decide whether the current LAI/CGI belongs to the l

ocal VLR or adjacent VLR

Home BSC DPC1～ 10 are used to identify which BSC this LA or cell belo

ngs to.

Call Source Code and Office No. defined in CALLSRC table and OFC tabl

e.

28 Internal Use


Add wireless MGW

Command : ADD RANMGW

This command is used to create the connection between the BSC office

direction and MGW.

Office Number is used to identify an office direction of an entity that a

specific MGW is connected to, It is defined in the ADD OFC command.

Media Gateway Index is defined in ADD MGW command.

29 Internal Use


Configuring A interface circuit pool:

Command : ADD ACPOOL

This command is used to set the bearer capability of A-interface circuit.

Circuit Pool Number is unique in one office.

GSM Bearer Capability define the service ability of the A interface circuit

pool.

30 Internal Use


Configuring A interface trunk group:

Command : ADD AIETG

Trunk Group Number : The parameter refers to the number of an A

interface trunk group.

MGW index: The parameter indicates the index number of an MGW to

which a trunk group belongs.

Circuit pool No.: It refers to the circuit pool number of A interface in the

local office,

WCSU to which the A interface trunk circuit belongs.

Start circuit and End circuit are used internally in the MSOFTX3000. It

is uniquely numbered in the same WCCU or WCSU.

Start circuit CIC refers to the unique indicator of an A interface circuit. It

must correspond to the Start CIC at the BSC side.

Start circuit termination ID: It refers to the ID of a termination

corresponding to the start circuit. It is an important parameter to identify

a physical circuit, and is used to indicate through which E1 the MGW is

connected to BSC. This parameter needs to be configured in MGW to

make Termination ID correspond to E1 timeslot one to one, so as to get

the start termination ID of the E1 connecting with BSC.
