g. Set Central Office shelves to CO and Remote Terminal shelves to
RT.
h. If TBOS is enabled, each shelf should be set to a unique TBOS
Address.
i. The TBOS Link is for shelves in a CO connected to TBOS. It pre-
vents failure of a single shelf in a bay from causing a TBOS link fail-
ure. The TBOS primary setting assigns a shelf as a backup for a
group of shelves that share the same TBOS link. The secondary
setting provides a secondary backup. Typically, the shelf cabled to
the TBOS is set for PRIMARY and the second shelf in the bay is set
for secondary. All other shelves in the CO bay that are associated
with that TBOS link are set for NORMAL. All shelves in the RT are
set for NO-TBOS.
j. TBOS Remote allows TBOS to be reported over the DCC. In order
for TBOS to be communicated from an RT, TBOS Remote must be
enabled at both the CO and RT shelves.
k. Idle Channel Signal should be set to AIS (default).
4. Issue the
set-fecom:dcc-all:com=enabled;
command to enable
far-end communications in each shelf.
5. Issue the
rtrv-fecom
; command to verify User Side (us) and Network
Side (ns) settings for each address corresponding to an OLIU per the fol-
lowing table:
