The following are the references in this section:
• Features and Services (553-3001-306)
• Administration (553-3001-311)
This chapter outlines the characteristics, application and operation of the
NT8D15 E&M Trunk Card. The information is intended to be used as a guide
when connecting customer-provided apparatus to the trunk circuit.
NT8D15 E&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 & M type I signaling trunks (non-ESN)
• two-wire dial repeating trunks
• two or four wire tie trunks
• four-wire E & 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 shows a matrix of the trunk types and signaling supported by the
NT8D15 E&M Trunk Card.
