ADTRAN T200 FNID specifications Table A. Front Panel Functions, Connections, Indicator Description

		Table A. Front Panel Functions
Indicator	Description
DSL	Indicates five possible states of the quality of the DSL signal
	Off	No synchronization of FT1 DP and FNID
	Red	Poor signal quality (≥10-7BER)
	Yellow	Marginal signal quality (≤2 dB margin above 10-7BER)
	Green	Good signal quality (≤2 dB margin above 10-7BER)
	Blinking	An error detected on the loop will cause this LED to blink briefly
DS1	This LED indicates three possible conditions described below.
	Off	The customer-side DS1 signal is absent or in a format that does not match the provisioned options
	Blinking	Indicates an error has been detected on the DS1 interface
	On Solid	The customer-side DS1 signal is present and synchronized
LBK	This LED indicates two possible loopback states as described below.
	Off	Unit is not in loopback
	On Solid	Local (FNID) loopback is active
RS-232	DB9 connector for craft interface. Allows connection to controlling terminal. For further information, refer to
	subsection 6 of this practice.
REM LBK	Remote Loopback. Push button to toggle Loopback active/inactive.
LOL LBK	Local Loopback. Push button to toggle Local Loopback active/inactive.

3. CONNECTIONS

All connections of the FNID are made through card edge connectors. Table B gives the card edge pin assignments for the FNID circuit pack. The circuit pack operates in either the standalone chassis (P/NÊ1242034L2), the ADTRAN HR4 HDSL shelf (P/NÊ1242008L1), or the ADTRAN HR12 HDSL shelf (P/NÊ1242007L1).

When the circuit pack is installed in any of the FNID enclosures, all connections are made through the enclosure backplanes. See the following ADTRAN documents for more information:

¥61242007L1-5, HR12 I/M

¥61242008L1-5, HR4 I/M

¥61242034L2-5, T400 Single Mount I/M (removable RJ-48 jacks)

NOTE: Ensure chassis ground is properly connected for either standalone or shelf-mounted applications.
