7. Lower order cross-connection units of type LOXC40G3S/1 (3 slots wide) cannot be
used in a system with a maximum switching capacity of 160 Gbit/s. However, the
universal slots 2/3/4 and 17/18/19 can be used for lower order cross-connection units
of type LOXC40G3S/1 (3 slots wide) after the system has been upgraded to a
maximum switching capacity of 320 Gbit/s.
8. XC160 cross-connection and timing units support O
9. It is recommended to use two XC160 cross-connection 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-connection and timing unit is also possible.

LXC320 configuration rules
In 320-Gbit/s configurations the following rules and guidelines apply:
1. The maximum switching capacity of the system is 320 Gbit/s (6144 × 6144
VC-3/STS-1; 2048 × 2048 VC-4).
2. Only XC320 or XC640 cross-connection and timing units can be provisioned in slot 9
and slot 10. However, the maximum switching capacity that can be used is 320 Gbit/s,
and the slot equipage rules as described above apply independent of whether an
XC320 or XC640 is used.
When an XC160 cross-connection and timing unit is installed in slot 9 or slot 10, then
the green activity LED of that XC160 will be flashing, and a
