ISL configurations
The ISDN Signaling Link (ISL) is used on PRI/DTI connections. The ISL
feature operates in two modes, shared and dedicated.
Shared mode
The DCHI supports ISDN PRI signaling for both PRI and ISL trunks.
Dedicated mode
In this mode, the DCHI supports ISL trunks using ISDN PRI signaling. The
D-channel communicates with the far end using a dedicated leased line,
dialup modem, or DTI trunk.
