Extended Hardware Modes

General Description

The evaluation board includes a socketed line interface

device and all support components necessary for

evaluation. The board is powered by an external 5 Volt

supply.

The board may be configured for 100

Ω twisted-pair

T1, 75

Ω coax E1, or 120 Ω twisted-pair E1 operation.

Binding posts are provided for line connections. Sev-

eral BNC connectors are available to provide system

clocks and data I/O. Two LED indicators monitor de-

vice alarm conditions. The board supports all line

interface operating modes.
