The FiberReach narrowband shelf consists of upper and lower subshelves for
channel units. Each subshelf can contain up to six channel units each, for a total
of 12 channel units per narrowband shelf. Each channel unit in the Narrowband
Shelf requires the following DS0 timeslots depending on the type of service
provided by the channel units.
■
POTS or Special Services: up to 4 DS0 time slots per channel unit
■
ISDN services:(2B&D): up to 9 DS0 time slots per channel unit.

DDM-2000 FiberReach Narrowband Shelf ONU (Release 4.4 and Later)
8
Using the CIT, you can provision each DSX-1 signal feeding a
V-DT
in the NBS to
any one of the following two modes:
■
Quad Mode
:
In this state, the DSXBIU continuously attempts to find or
frame-up on the DSX-1 input, establish the message link, alarm any DSX-1
faults, and provide service to a set of six channel unit slots in the NBS. This
mode is similar to the service provided with Release 4.3 where a single
server can feed a six-slot V-DT for 24-line service. You can also provision
the quad mode for 12-line service.
■
Octet Mode
:
In this state, the DSXBIU continuously attempts to find or
frame-up on the DSX-1 input, establish the message link, alarm any DSX-1
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 DS0s instead of
the four DS0s supported in the quad mode. The octet mode allows the use
of the maximum number of ten ISDN lines 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.
NOTE:
See Chapter 2 in the
SLC-2000 Access System Applications, Planning and
Ordering Guide
for a description of V-DT.
