This chapter outlines the characteristics, application and operation of the
NT8D15 E and M TrunkCard. The information is intended to be used as a
guide when connecting customer-provided apparatus to the trunk circuit.
NT8D15 E and M TrunkCard has fouridentical trunk circuits. Each circuit
can be configured independently by software control. The trunk circuits on
the card support the following types of trunks:
•two-wire E and M type I signaling trunks (non-ESN)
•two-wire dial repeating trunks
•two or four wire tie trunks
•four-wire E and M type I and II signaling type II trunks (ESN and
Non-ESN applications)
•Paging (PAG)
TypeI signaling (as on the two-wire E & M trunk) utilizes two signaling wires
plus ground. Type II signaling utilizes tow pairs of signaling wires and is
used by most electronic switching systems.
Table269 "Supported trunk and signaling matrix" (page 719) shows a
matrix of the trunk types and signaling supported by the NT8D15 E and M
TrunkCard.
