SPQ
810/811 DT Server
For Use With FR NBS
General:
The
SPQ
810/811 DT Server is used to provide support for the FiberReach NBS.
Each NBS supports a total of 48 tip-ring pairs which are assigned by provisioning the
DT server to each DSX-1 signal feeding a V - DT in the NBS (see Figures 1 and 2) to
any one of the following two modes:
Quad Mode: The Quad Mode requires 2 DS1 servers. The DSXBIU continuously
attempts to find or frame-up on the DS1 input, establish the message link, alarm any
DS1 faults, and provide service to a set of six channel unit slots in the NBS. You can
provision the quad mode for 24- or 12- line service, supporting 24 or 12 tip-ring pairs,
respectively.
Octet Mode: The Octet Mode requires 4 DS1 servers. The DSXBIU continuously
attempts to find or frame-up on the DS1 input, establish the message link, alarm any
DS1 faults, and provide service to a set of three channel unit slots in the NBS. In the
octet mode, each channel unit slot can support eight time slots (DS0s) instead of the
four time slots (DS0s) supported in the quad mode. The octet mode allows the use of
the maximum number of ten ISDN lines per quadrant in the NBS when using the
SPQ
494 quad ISDN channel units along with the AUA94 dual ISDN channel units.
You can provision the octet mode for 24-line service only. In octet mode, each server
supports 12 tip-ring pairs only.
