ERIFICATION
Once the H2TU-R-402 is installed, verify that it is operating properly by monitoring the
Status LEDs on the front panel.
LED Status
Status (STAT) LED
Solid green Indicates normal operation: the HDSL2 span is synchronized.
Blinking once
per second
Loss of Sync Word
(LOSW) LED
Solid red Indicates that the HDSL2 loop has lost synchronization.
Local Loss of Signal
(LLOS) LED
Solid red Indicates a loss of the DSX-1 signal at the H2TU-C.
Remote Loss of Signal
(RLOS) LED
Solid red Indicates a loss of the DS1 signal at the H2TU-R-402.
HDSL2 Block Error Rate
(HBER) LED
Solid green Indicates that the span connected to the H2TU-R-402 has no HBER alarm.
Solid red Indicates that the span connected to the H2TU-R-402 has crossed the HBER
Margin alarm (MARG) LED Shows the status of the MARG alarm for the span connected to H2TU-R-402.
Solid green Indicates that the HDSL2 span connected to the H2TU-R-402 is synchronized.
Solid red Indicates that the span connected to the H2TU-R-402 has crossed the MARG
Line code (B8ZS) LED
Solid green Indicates that the system is provisioned for B8ZS line code.
Loopback (LBK) LED
Solid yellow Indicates there is loopback activated at the H2TU-R-402.
L
OGGING ON TO THE
The H2TU-R-402 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-402 front panel.
Logging on creates menus and screens for the H2TU-R-402 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.
