PATTON ELECTRONICS G.703/G.704 SDSL MODEM

SPECIFICATIONS

Clocking Modes: 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.
ER: Flashing red ER LED indicates errors in
511 test pattern
TM: The yellow TM LED indicates that
modem is in a test mode
(Local/Remote Loopback or 511/511E test
pattern). Opaque TM LED indicates normal
operation.
