Function
Identifies the list number of the H2TU-C-202.
A switch bank, located on the board, containing eight switches. (See

The Status LEDs indicate the following conditions:
Solid red when a fuse alarm is present.
Flashes red once per second when a local alarm is present.
Flashes red five times per second when a remote alarm is present.
Off when no alarm is present.
Solid green while all HDSL2 spans are up.
Flashes green once per second during a loop acquisition on the span.
Flashes green five times per second when a margin or loop attenuation
threshold is exceeded.
Solid yellow when the H2TU-C-202 is in the NLOC or CREM loopback mode.
Flashes yellow five times per second when the system is armed.
Off when the system is not armed or in loopback mode.
Solid green when DSX-1 signal is present and no alarm is present.
Flashes green once per second for BPV, FERR, UAS, or CRC DSX-1 error.
Flashes green five times per second when network side framing or line code
provisioning does not match the DSX-1 signal being received.
Off when DSX-1 signal is not present.
Provides non-intrusive bridging jack access to (IN) and from (OUT) the HDSL2
span at the DSX-1 interface. Allows the two DS1 payloads to be monitored.
Provides bidirectional communication between the unit and an external
terminal to allow configuration and performance monitoring through the
Maintenance Terminal screens.
Provides the human-readable Common Language Equipment Identifier (CLEI)
code number and the Equipment Catalog Item (ECI) bar code number.
