2. Each B-channel uses the Individual Route Number.
STEP 1: Assign the numbering (LCR) data to access to ISDN.
STEP 2: ARTD - Assign the route data. (Refer to “Chapter 3”)
STEP 3: ATRK - Assign the trunk data of Bch. (Refer to “Chapter 3”)
Assign 23 Bch
 to RT30, 24 Bch to RT32 in this example. Note that trunk data assigned in
this step is for Bch only. Dch’s trunk data should be set after STEP 6: ACIC1 command...
