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.
