DATA PROGRAMMING

Assignment of FCH Related Data

Specifications for the SDH data setting are described below.

1.When FCCS and CCIS links are used together in the network, the different route number must be assigned to each Connection Trunk (B-ch), Connection Link (D-ch), Speech Line for CCIS and Signal Line for CCIS.

Example:

Available

Network	Route	Route￿
		Number
FCCS	Connection Trunk	RT=10
	Connection Link	RT=11
CCIS	Speech Line	RT=20
	Signal Line	RT=21

⋅Not Available

Network	Route	Route￿
		Number
FCCS	Connection Trunk	RT=10
	Connection Link	RT=11
CCIS	Speech Line	RT=10
	Signal Line	RT=11

The same route number can not be used for the different route.

2.System data (SYS1, INDEX 531) must be assigned prior to the trunk data assignment for the SDT.

3.When the SDT card is used to replace with the DTI card, and the trunk data has already been assigned for the DTI, perform the circuit card initialization after setting system data.

4.When assigning Connection Links to the SDT card, a maximum of 512kbps (8ch) TS (Time slot) can be used as Connection Link (data link). Assignment order of TSs used for Connection Link between SDT and FCH must be identical. Any TS can be used for Connection link.

7.2.1Data Programming

STEP 1: ASYDL

Designate the MG of accommodating the SDT circuit card.

b0-b7 Assign “1” to the bit number corresponding to the mounted MG number.

Note: SDT can be mounted in the odd MG only.

STEP 2: ACRD

Assign the Connection Route Class data.

•Connection trunk (for Voice) C_RT: 10

TF=3 TCL=4 RLP=2 LSG=12
