This chapter outlines the characteristics, application and operation of the
NT8D15 E and M Trunk Card. The information is intended to be used as a
guide when connecting customer-provided apparatus to the trunk circuit.
NT8D15 E and M Trunk Card has four identical 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)
Type I 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.
Table 269 "Supported trunk and signaling matrix" (page 719) shows a
matrix of the trunk types and signaling supported by the NT8D15 E and M
Tr unk Card.
