Network (G.703/G.704), Internal, Receive
Recover

Line Rate:

2048 kbps

Diagnostics:

V.52 compliant (511/511E) pattern generator
and detector with error injection mode.
Remote Loopback (toward fiber line) and
local loopback (toward G.703/G.704 Net-
work) controlled by a single front panel
switch

LED Status:

The following LEDs are displayed on the
front panel:
Fiber:

The green Fiber LED indicates reli-

able data on the fiber side
E1:

The green E1 LED indicates reliable

data on the G.703/G.704 side
LOS:

The red LOS indicates that syncro-

nization between modems has not been
established. Blinking red LOS LED indicates
the presense of coding errors.
NS:

The red NS LED indicates that the sig

nal on the fiber side is too weak to be
detected.
