6.
NOTE:
The cct parameter of the
ent-crs-vt1
command specifies the
cross-connect type. The valid values are
two-way
,
dc
, and
locked
.
Two-way applies to add/drop, hairpin, 0X1 ring, and pass-through
connections. The
dc
parameter applies to dual ring interconnection (DRI)
applications. The
locked
parameter supports non-path-switched DS1
applications where a DS1 is cross-connected to a specified channel in a
specified direction of the ring interface (Figure 13). Provisioned AIS or
unequipped signal is transmitted in the other direction around the ring,
but is not alarmed at any pass-through nodes or the other terminating
node with locked cross-connections present for the same channel. Any
signal received in the same channel from the other ring interface is
ignored.
Determine the cross-connect type (
cct
) to be made at each node for the
service being established.
7.
NOTE:
In dual homing configurations (Figures 5 and 6), OLIU circuit packs must
be installed in the correct slots in the host OC-3 nodes to support the
direction of traffic required. For example in Figure 5, for traffic to be
routed between Node 1 and the FiberReach system, the 27G-U/27G2-U
OLIU must be installed in FUNCTION UNITS GROUP A, B, or C, slot 1
of Node 5 and FUNCTION UNITS GROUP A, B, or C, slot 2(P) of Node
4. This is required because traffic entering Node 5, slot FUNCTION
UNITS-A-1 from the FiberReach shelf is automatically connected to the
MAIN-1 OLIU when cross-connections are made. Traffic entering slot
FUNCTION UNITS-A-2(P) is automatically connected to the MAIN-2
OLIU.
NOTE:
In single homing configurations (Figure 9), the 27G-U/27G2-U OLIU in
FUNCTION UNITS GROUP A, B, or C, slot 1 of the OC-3 shelf must be
connected to the MAIN-1 OLIU in the FiberReach shelf. The
27G-U/27G2-U OLIU FUNCTION UNITS GROUP A, B, or C, slot 2(P) of
the OC-3 shelf must be connected to the MAIN-2 OLIU in the FiberReach
shelf.
Use the
rtrv-eqpt:
command at each node in the network to verify that
each shelf is properly equipped for the service being established. Ensure that
OLIU circuit packs are installed in the correct slots in the host OC-3 nodes.
