NOTE:
The Remote NE Status (rnestat) parameter of the
set-ne: command must be enabled prior to designating
the AGNE(s) and alarm group numbers.
NOTE:
Shelves may be designated as an alarm gateway network
element (AGNE) and assigned an alarm group number.
(Default alarm group number is 255.) At least one AGNE is
required per alarm group. One primary AGNE and one
backup per alarm group is recommmended. For a network
greater than 16 nodes, the AGNE and TL1 GNE should be
on separate nodes. The AGNE parameter of the set-ne:
command may have been set to yes on each new shelf
during shelf turnup procedures to suppress an AGNE
communication failure alarm.
Use the set-ne: command to designate the AGNE(s) and
alarm group numbers, as required.
14.
NOTE:
Only one remote DDM-2000 OC-3 shelf is allowed in this
single-homed ring configuration.
NOTE:
This single-homed ring configuration requires that the
FUNCTION UNITS ( ) 1 OLIU on the OC-12 shelf connect to
the MAIN 1 OLIU at the first OC-3 shelf from the OC-12
shelf. MAIN 2(P) OLIU at the OC-3 shelf (node) connects to
FUNCTION UNITS ( ) 2(P) OLIU on the host OC-12 shelf.
See Figure 1. This procedure will establish the ring
configuration starting from the OC-12 host node (near end)
to the OC-3 node and back to the host OC-12 node.
At the near end, remove the optical loop from the OLIU (for
example in Figure 1, Node 5 OC-12 shelf FUNCTION UNITS A 1)
associated with the optical span being established. At the other
end of the optical span, remove the optical loop from the
associated OLIU (for example, in Figure 1, Node 7 OC-3 shelf
MAIN 1 OLIU).
