T- 1 Tr u n k i n g
Description
The T-1 trunk card can be used to connect 24 lines (24 channels per T-1 circuit) from a CO to
the system. These lines can be any mix of inbound WATS, outbound WATS, standard DDD
lines, DID lines, or TIE lines. The system also supports Fractional T-1 Service.
T-1 Signaling Type
Description
The T-1 trunk card provides the STSe Systems with the ability to connect to T-1 trunk circuits.
The T-1 trunk card supports either the standard D4 framing format with Alternate Mark
Inversion (AMI) or Extended Superframe (ESF-B8ZS) format coding. The system can support
TIE, loop start, ground start, and DID signaling per channel. The T-1 trunk card fits into one
card slot.
The T-1 signaling protocols provided are: Loop Start, Ground Start, TIE. The STSe Digital
Systems use the TIE signaling simulation from the Central Office to add the additional
protocol of Direct Inward Dial (DID).
T-1 trunking provides services called Automatic Number Identification (ANI) and Dialed
Number Identification Service (DNIS). The T-1 feature supports both of these services. The
STSe Digital Systems support ANI, DNIS, or an ANI and DNIS combination on a per channel
(line) basis.
