LED STATUS

DSL	●	Off	No synchronization between H2TU-C and H2TU-R on the loop.
	●	Red	Poor signal quality on the loop (>10-7BER).
	●	Yellow	Marginal signal quality on the loop (≤ 2 dB margin above 10-7BER).
	●	Green	Good signal quality on the loop (> 2 dB margin above 10-7BER).
DSX	● Off		Network side DSX-1 signal is absent or is in a format that does not match the provisioning
			of the HDSL2 circuit.
	✷ Blinking		Bipolar Violation (BPV), frame bit error (SF mode) or CRC error (ESF mode) detected at
			DSX-1 signal.
	● Solid		Network side DSX signal is present and synchronized.
ALM	● Off		No alarm condition detected.
	● Red		Detected local alarm condition (H2TU-C) or locally and remotely (H2TU-C and H2TU-R).
	● Yellow		Detected remote alarm condition (H2TU-R).
LBK	● Off		Unit is not in loopback or armed state.
	● Yellow		Active local bidirectional loopback from the H2TU-C toward the customer and the network.
	✷ Blinking		Unit is armed but not in active loopback condition.

BANTAM JACKS

MON

■Provides a nonintrusive tap to monitor characteristics of the DSX signal TX — monitors signal being received from the network

RX — monitors signal being transmitted to the network

EQ

■Provides an intrusive signal interrupting access point to the data stream TX — accesses the data stream being transmitted toward the customer RX — accesses the data stream being received from the customer

RS-232 DB-9 CONNECTOR

■Used to access the HDSL2 utilities menu tree via VT100 emulation software such as terminal, Hyper Terminal – Private Edition and ProComm Plus.

■There are two types of terminal emulation modes, Manual and Real-Time. To toggle between the two, type “CTRL” and “T.” To update the screens while in Manual Mode, press the space bar 3 times. Real-Time Update Mode is the default mode.

■Provision terminal port as follows:

Data Rate — 1.2 kbps to 19.2 kbps

Asynchronous Data Format — eight data bits, no parity (none), one stop bit, and no flow control.

■When using a PC with terminal software, be sure to disable any power saving programs.
