ERIFICATION
Once the H2TU-R is installed, verify that it is operating properly by monitoring the Status
LEDs on the front panel.
LED/Status
ALM
Flashing red once per second Local Loss of DS1 Signal (LLOS) present at the H2TU-C.
Loop
Flashing green once per second HDSL2 loop synchronization attempt.
Flashing green 4 times per second HDSL2 margin alarm or loop attenuation alarm present at the H2TU-R.
Flashing green 10 times per seconds HDSL2 CRC error present at the H2TU-R.
ESF
Flashing green once per second ESF framing and frame error/CRC present on the incoming DS1 signal.
SF
Flashing green once per second SF framing and frame error present on the incoming DS1 signal.
B8ZS
Flashing green once per second B8ZS and string of excess zeros detected on the incoming DS-1 signal.
AMI
Flashing green once per second AMI and BPV detected on the incoming DS-1.
LBK
Flashing yellow once per second Loopback in H2TU-R towards customer.

OGGING ON TO THE
The H2TU-R supports local and remote logon through a maintenance terminal (ASCII
terminal or a PC running terminal emulation software) connected to the craft port on the
H2TU-R front panel.
Logging on creates menus and screens for the H2TU-R that are replications of those viewed
at the H2TU-C. Once logged on, you can view system settings and inventory, initiate
loopbacks, monitor performance, and configure the circuit.
