636 NT8D15 E and M Trunk card
Type I signaling uses two signaling wires plus ground. Type II and DX
signaling uses two pairs of signaling wires. Most electronic switching
systems use Type II signaling.
Table 241 "Trunk and signaling matrix" (page 635) lists the signaling and
trunk types supported by the NT8D15 E and M Trunk card.

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.
