OMPATIBILITY
The HLU-200 List 1A operates as a channel card in a DSC Litespan-2000
Channel Bank. The Litespan-2000 system consists of a Central Office (CO)
bank connected to a remote bank over an Optical Carrier 3 (OC3) fiber link.
Each bank has slots for 56-channel plug-ins. The HLU-200 is typically
installed in the remote bank, where it is used to transmit a T1 payload to a
remote HRU-412. The transmission is over two unconditioned HDSL cable
pairs, with or without doublers. The HLU-200 is the HDSL equivalent to an
AT1U channel card, used to transmit a T1 payload to a remote location over
conventional T1 spans.
The HLU-200 List 1A is compatible with Litespan-2000 software releases
7.1.x and 8.1.x and above. The HLU-200 List 1A is not compatible with the
Litespan-2000 Management System and must be maintained, provisioned
and monitored from the front-panel RS-232 maintenance port.
The HLU-200 can be cross-connected to another HLU-200 or to another
asynchronous T1 channel unit in the same channel bank or in the distant
channel bank. These point-to-point dedicated circuits are initiated by issuing
the standard TL1-based cross-connect commands to the Maintenance and
Test Interface (MTI) card. The MTI card identifies the HLU-200 List 1A as
an AHT1U plug.
