COMPLIANCE CODES
This product is intended to be installed in an enclosure with an
Installation Code (IC) of “B” or “E” and in Restricted Access Locations
only. Up to –200 Vdc may be present on telecommunications wiring.
The DSX-1 interface is intended for connection to intra-building
wiring only.
LED STATUS
DSL ●● Off No synchronization between H2TU-C and H2TU-R on the loop.
● Red Poor signal quality on the loop (>10
-
7
BER).
● Yellow Marginal signal quality on the loop (≤ 2 dB margin above 10
-
7
BER).
● Green Good signal quality on the loop (> 2 dB margin above 10
-
7
BER).
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.
