Prerequisites Before the operation, it is required to confirm:
� The signaling interworking data planning and negotiation be-tween MSCS and other office are completed.
� The data configuration of local office is completed.
� The MML Terminal window is opened.
Context Perform this procedure to configure the basic information of an interconnected adjacent office.
Steps 1. If no exchange is specified, execute command SET on the MML Terminal window or select a NE from the system tree to spec-ify the exchange to be configured.
Example: Select the MSCS exchange with ID as 11 from the system tree.
SET:NEID=11;
2. Configure an adjacent office. The command is ADD ADJOFC.
describes the main parameters in the ADD ADJOFC command.
Parameter Name
Parameter
Description Instruction
ID Office ID
It is a mandatory parameter.
It is the identification number of the adjacent office, ranging from 1 to 3000. It is usually configured as the exchange ID of the adjacent office during the all-network planning NAME Alias It is a mandatory parameter,
which is user-defined alias
Parameter Name
Parameter
Description Instruction
NET Network type
It is a mandatory parameter, indicating the network type of the SPC used for connecting the local office to the adjacent office when the local office is configured with several signaling points. The default is the network type of this SP when there is only one SP in the local office.
OFCTYPE Office type
It is a mandatory parameter.
Refer to Table 69 for the configuration of adjacent office at the network side.
SPCFMT Signaling point code format
TRIPLE_DEC is selected by default.
SPCTYPE Signaling point code type
DPC Signaling point code
It is a mandatory parameter.
It is selected according to the SPC type of the adjacent office.
In China, all the NEs adopt 24-bit SPC, except for BSC that adopts 14-bit SPC. Configure it according to the signaling point planning.
RC Area code
It is an optional parameter, designating the area code of this adjacent office. This configuration has impact on the area code added by the calling number.
ASSOTYPE Association Type
It is an optional parameter.
Select AM_SURE (direct-associated mode) or
AM_QUASI (quasi-associated mode) according to the networking conditions.
SPTYPE
Signaling point type, including SEP, STP, and STEP
Select SEP (signaling end point), STEP (signaling transfer/end point) or STP (signaling transfer point) according to the role of the adjacent office in the signaling network.
Parameter
It is an optional parameter. In general, select NATIONAL for domestic use.
TAG
Office Attribute, including:
ISNI (Has ISNI Function)
TRANS (Translate Node)
TEST (Need Test Info:0X02/0X01)
It is an optional parameter
TEST Test flag
It is an optional parameter, for setting whether the MTP3 link actively initiates the link test after entering in the service status. It is selected by default.
BANDFLAG Broadband attribute
It is an optional parameter with a default of NO. It is used for SCCP to judge whether to use the LUDT message.
The maximum length of a broadband link message is 4,000, and that of a narrowband link message is 255. Because the MTP layer does not have the segmentation function, the incorrect configuration of this parameter probably causes the long packet to be discarded.
Select this parameter when

It is an optional parameter.
CHINA and ITU are used for the NO.7 signaling networking of the ITU standards. ANSI is used for the No.7 signaling networking of the American standards.
CLST Cluster ID
It is an optional parameter.
The cluster number should be configured in ADD CLST.
The parameter ranges from 0 to 65535, with a default of 65535. the PCM code mode)
It is an optional parameter, with a default of CIC_PCM(CIC using PCM Code Mode Starts Load Control)
Parameter
RELATE-DOFC1 Related office ID It is an optional parameter, ranging from 0 from 3000

For example, configure the HLR adjacent office during TDM connection. The office ID is 104, the network type is 1, the signaling point code is 20.250.31, the office type is HLR/HLRe, and the domain type is SCN. For the other parameters, select the default value. the command is as follows:
ADD ADJOFC:ID=104,NAME="HLR",NET=1,OFCTYPE="H LR/HLRe",SPCFMT=TRIPLE_DEC,SPCTYPE=24,DPC="20.25 0.31",RC="25",ASSOTYPE=AM_SURE,SPTYPE=SEP,SSF=N ATIONAL,SUBPROTTYPE=DEFAULT,TEST=YES,BANDFLAG

For example, configure the MSCS adjacent office. The net-work type is 1, the alias is MSCS105, the signaling point code is 20.250.1 the signaling point code format is 24, the associ-ation type is AM_SURE, and the office type is DOMTOLL&LO-CAL&MSCSERVER&OA. For other parameters, select the de-fault value. The command is as follows:
ADD ADJOFC:ID=105,NAME="MSCS105",NET=1,OFCTYP E="LOCAL"&"DOMTOLL"&"OA"&"MSCSERVER",SPCFMT=TRI PLE_DEC,SPCTYPE=24,DPC="20.250.1",RC="25",ASSOTY PE=AM_SURE,SPTYPE=SEP,SSF=NATIONAL ,SUBPROTTYP E=DEFAULT,TEST=YES,BANDFLAG=YES,PRTCTYPE=CHIN A,CLST=65535,INFO="CIC_PCM",RELATEDOFC1=0;
