Loop Start Trunks
Loop Start Trunks can be connected to the SL1000/SL1100 system. Loop Start is assigned per trunk
at the associated unit.

ISDN PRI

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.
