Description
The T-1 trunk card provides the
connect to digital 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, however, it takes up two card slots worth of
time slots.
The T-1 signaling protocols provided are: Loop Start, Ground Start, TIE.

the following types:

None is used for fractional T-1 spans. All unused channels in a
fractional T-1 span should be marked as None.
Disconnect supervision is not supported for Loop Start
emulation of T-1 circuits.
Software supports disconnect supervision for ground start
emulation of T-1 circuits.
The DID signaling (wink, delay) is controlled in Flash 45. DNIS
digits from the carrier are routed via the DID table
programming in Flash 44. This simulates incoming DID service
only.
The ANI number is treated and routed as an ICLID number. It
follows the Flash 43 programming for routing information.
