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, a 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.
Figure 5-43 provides an example.

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 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 Connection links to the SDT card are being assigned, 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.
7.2.1 Data Programming
STEP 1: ASYDL
Designate the MG 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.
