4. Only the XC320/B variants of the XC320 cross-connect and timing units support
ONNS applications.
5. It is recommended to use
two
XC320 cross-connect and timing units. Thus, both
the cross-connnect as well as the timing function are automatically 1+1 equipment
protected. However, an LXC configuration with a single, but unprotected XC320
cross-connect and timing unit is also possible.
LXC640 configuration rules
These rules and guidelines apply when the
Maximum Switch Capacity
of the system
is set to
LXC640
(640 Gbit/s):
1. The maximum switching capacity of the system is 640 Gbit/s (12288 × 12288
VC-3/STS-1; 4096 × 4096 VC4).
2. Port units can be used in
all
universal slots, and
all
universal slots can be used.
That is also valid for port units with a transmission capacity of 20 Gbit/s (e.g.
OP2G5D and OP10D circuit packs).
3. Only XC640 cross-connect and timing units can be provisioned in slot 9 and
slot 10.
If any cross-connect and timing unit other than an XC640 is installed in slot 9 or
slot 10, the green activity LED of that cross-connect and timing unit will flash, and
a “Circuit Pack Type Mismatch” alarm will be reported.
