Basic ISL implementation
Implement dedicated mode
Use
Procedure 38 "Implementing dedicated mode" (page 232)
to configure
basic ISL capability. It applies to analog TIE Trunks that are used as
B-channels. When DTI/PRI trunks are also used, LD 17 digital loop (DLOP)
and LD 73 (digital data block-DDB) must also be configured with the
appropriate clocking and threshold settings.
The DCHI in this case uses the NTAK02 circuit card and does not support
ISDN PRI signaling. The DCHI is reserved for ISL use only. The D-channel
can communicate with the far-end by means of a dedicated leased line
modem or dialup modem.
For ISL dedicated mode using a dialup modem, a 500 set, TIE Trunk route
and member have to be configured (used for D-channel).
Configuring dedicated mode involves four major steps:
Procedure 38
Implementing dedicated mode
Step
Action
1
Configure the D-channel for ISL (LD 17).
2
Enable ISDN option (LD 15).
3
Enable the ISL option on a per route basis, assigning a D-channel
for each route (LD 16).
4
Assign a channel identification to each trunk with the ISL option
(LD 17).
