APPENDIX A

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.
