Network Interface (NI)

The Network Interface (NI) port provides the connection to
the E1. This port complies with the applicable ANSI and
CCITT standards. Either the 120

Ω

DB15 or the 75

Ω

BNC

interface (adapter provided) may be used for the Network
Interface. The 75/120 selection must be made with the front
panel menus. For more information, see Wiring on page C-1.

Network Test Interface

The MON test jack provides a bridges access jack for non-
intrusive monitoring of the incoming E1.

Nx56/64 Serial Interface

The Nx56/64 provides a serial interface that operates from
56kbps to 2.048 Mbps. The Nx56/64 can be configured as a
V.35, V.36, EIA-530, or V.11 electrical interface through the
front panel menus.

Control Port Input

The control port input provides an EIA 232 input from a PC
or a modem for control of the ESU LT. You can also use it as a
chain input from another ESU LT or ESU 120e. For more
information, see Wiring on page C-1.

Chain Port Output

The chain port output provides an EIA-232 output to chain
control to other ESU LTs or ESU 120es. For more information,
see Wiring on page C-1.

Software Management

Front Panel

The front panel provides complete and easy control of all
items that can be configured through menu-guided options.
The front panel LCD also displays the status of operation and
performance reports for the unit. A complete discussion of
the operation of the front panel is found in Chapter 3,
Operation on page 3-1. The menu options are found in
Chapters 4 through 7.
