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

1Configure the D-channel for ISL (LD 17).

2Enable ISDN option (LD 15).

3Enable the ISL option on a per route basis, assigning a D-channel for each route (LD 16).

4Assign a channel identification to each trunk with the ISL option (LD 17).
