DID
Refer to the Direct Inward Dialing (DID) on page 1-215
Loop Start Trunks
Loop Start Trunks can be connected to the SL1100 system. Loop Start is assigned per trunk at the
associated unit.
ISDN PRI
Refer to the ISDN Compatibility on page 1-460
T1-E1 Trunks
The T1/PRI/E1 Interface gives the system T1/E1 trunking ability. This unit uses a single universal slot
and provides up to 24/30 trunk circuits. In additional to providing digital-quality trunking, the T1/PRI
Interface allows you to have maximum trunking ability with fewer units. This in turn makes more
universal slots available for other functions.
Conditions
• When adding or removing padding for trunks, use PRG 14-01 for all trunks.
