ERIFICATION
Once the H2TU-R is installed, verify that it is operating properly by monitoring the Status
LEDs on the front panel (refer to Table 1).
LED Status
Alarm (ALM) LED
Solid red Indicates a Loss of Signal (LOS) condition at the T1 input of the H2TU-R.
Blinking Indicates a LOS condition at the T1 input of the H2TU-C line unit.
HDSL2 LED
Solid green Indicates HDSL2 loop is in sync.
Blinking once
per second
Blinking 4 times
per second
Blinking 10 times
per second
OFF Indicates no activity on the HDSL2 loop.
DS1 Framing (FRM)
LEDs (ESF and SF)
ESF LED = Solid green Indicates Extended Super Frame (ESF). The LED blinks once per second when a
SF LED = Solid green Indicates Super Frame (SF). The LED blinks once per second when a frame error
OFF Indicates unframed or no signal.
DS1 Code LEDs (B8ZS
and AMI)
B8ZS LED = Solid
green
AMI LED = Solid green Indicates that the user DS1 line code option is set to Alternate Mark Inversion
Loopback (LPBK) LED
Solid yellow Indicates Network Remote Loopback (NREM).
Blinking once
per second
Blinking 4 times per
second Indicates the H2TU-R is in an Armed state.
L
OGGING ON TO THE
The H2TU-R supports local and remote logon through a maintenance terminal (VT-100 or
a PC running VT-100 terminal emulation software) connected to the craft port on the
H2TU-R front panel.
The H2TU-R accesses menus and screens that are replications of those viewed at the
H2TU-C. You can also view system settings and inventory, initiate loopbacks, monitor
performance, and configure the circuit.

Indicates
Shows alarm states for remote and local Loss of Signal (LOS).
Displays HDSL2 Loop condition.
Indicates the HDSL2 loop is trying to acquire sync.
Indicates a margin alarm condition on the HDSL2 loop.
Indicates a Cyclical Redundancy Check (CRC) error on the HDSL2 loop.
Indicates framing patterns. If DS1 signals are not detected, the ESF, SF, B8ZS, and
AMI LEDs will not light.
frame or CRC error occurs.
occurs.
Indicates DS1 code options. If DS1 signals are not detected, the ESF, SF, B8ZS,
and AMI LEDs will not light.
Indicates that the DS1 line code option is set to Bipolar with 8-Zero Substitution
(B8ZS). The LED blinks once per second when a string of excessive zeros is
detected.
(AMI). This LED blinks once per second when a Bipolar Violation (BPV) is
detected.
Shows loopback states to and from the network and to and from the Customer
Interface (CI).
Indicates Customer Local Loopback (CLOC) loopback state.
