5. XC160 cross-connect and timing units support ONNS applications.
6. It is recommended to use
two
XC160 cross-connect and timing units. Thus, both
the cross-connect as well as the timing function are automatically 1+1 equipment
protected. However, an LXC configuration with a single, but unprotected XC160
cross-connect and timing unit is also possible.
LXC320 configuration rules
These rules and guidelines apply when the
Maximum Switch Capacity
of the system
is set to
LXC320
(320 Gbit/s):
1. The maximum switching capacity of the system is 320 Gbit/s (6144 × 6144
VC-3/STS-1; 2048 × 2048 VC4).
2. Port units can be used in
all
universal slots.
However, port units with a transmission capacity of 20 Gbit/s (for example an
OP2G5D/PAR8 parent board, equipped with 8 optical modules) can only be used in
the universal slots 2, 4, 6, 8, 13, 15, 17, 19, 22, 24, 26, 28, 33, 35, 37, and 39. The
slot to the left of a slot where such a port unit is installed has to remain
unequipped.
Cover all unequipped slots with blank faceplates.
3. Only XC320 or XC640 cross-connect and timing units can be provisioned in slot 9
and slot 10. The slot equippage rules as described above however apply
independent of whether an XC320 or an XC640 is used.
If an XC160 cross-connect and timing unit is installed in slot 9 or slot 10, the
green activity LED of that XC160 will flash, and a “Circuit Pack Type Mismatch”
alarm will be reported.
