Programming Isdn Equipment; Terminal Equipment For Bri Cards; Devices On An S Or Lt Loop (Bri Cards Only) - Nortel Modular ICS 6.0 Installer's Manual

A call presented to the Norstar system with service type
FX and SID 2 will be handled as follows:
• The ISDN setup message will specify FX with SID = 2
• The FX SID = 2 will be mapped to DISA DN digits 1234
The call will be answered with DISA

Programming ISDN equipment

DTI cards configured as PRI support various applications that
are enabled by PRI. For a list of the type of applications that
are support, see ISDN applications on page 173.

Terminal equipment for BRI cards

ISDN devices and terminals connected to the ICS must be
configured under the Hardware heading in system
programming. You choose directory numbers for ISDN
equipment from a pre-determined range of DNs (667-696).
Any of the ISDN DNs can be assigned to any U-LT or S loop,
but each can only be assigned to one loop and one device.

Devices on an S or LT loop (BRI cards only)

Terminal equipment using a U-LT loop or S loop must be
assigned an ISDN directory number (ISDN DN). This allows
the TE to be assigned lines and to communicate with other
devices connected to the ICS. Each DN can be assigned to only
one TE and one loop.
You assign ISDN DNs to S loops and LT loops under Assign
DNs under Hardware. Each S or LT loop can be programmed
with eight ISDN DNs, but you cannot exceed a total of 30
ISDN DNs for the Modular ICS.
Once you have assigned ISDN DNs to a loop, designate one of
the DNs as a Loop DN. The Loop DN acts as a main ISDN DN
and completes the configuration of the loop.
