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.

NOTE:
In dual homing configurations, OLIU circuit packs must be
installed in the correct FUNCTION UNITS slots in the host
OC-12 nodes to support the direction of traffic required. For
example, see Figures 1 and 2. In Figure 1, if an OLIU is
installed in Node 5, FUNCTION UNITS group A, slot 1, traffic
will be routed toward Node 6 when cross connections are
made. The other end of the associated OC-3 ring must be
connected to an OLIU installed in slot 2(P) of the
FUNCTION UNITS group ( ) being used to terminate the
OC-3 line (for example, Node 4 in Figure 1). Traffic from
Node 4 will then be directed toward Node 3 when
cross-connections are made. In Figure 2, note that all traffic
from the OC-3 shelf will be directed to Node 8 because of
the slot positions that terminate the OC-3 line.
