ISL software implementation 289

Dedicated mode

The DCHI 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.

Note that the following implementation relates to analogue TIE trunks being used as B-channels. In the case where DTI/PRI trunks are also used, then LD 17 digital loop (2.0 Mb PRI) and LD73 (2.0 Mb PRI/SYTI) must also be configured with the appropriate clocking and threshold settings.

For ISL dedicated mode using a dialup modem, a 500 set, TIE trunk route and member must be programmed (used for D-channel). Table 106 "Configuring basic ISL capability" (page 289) summarizes the required steps.
