Cross-connection features

Cross-connection rates
1643 AM / 1643 AMS support bidirectional cross-connections for VC-3, VC-4 (VC-4
only 1643 AM with STM-4 aggregate) and VC-12 payloads. One arbitrary VC-4 from
each aggregate STM-1 or STM-4 (1643 AM only) signal can be used for connections
at a time. It is possible to select different VC-4 timeslots from aggregate east and
aggregate west.
VC-12 or VC-3 structured signals can be transported between the two aggregate lines
without timeslot interchange.
Loopback cross-connections are possible on VC-12 and VC-3 level.
Cross-connect architecture of 1643 AMS
The AMS transmission architecture is the same as the transmission architecture of the
STM-1 version of the 1643 AM. The main FPGA, the higher-order cross connect, and
the associated circuitry that are only used on the STM-4 version of the 1643 AM are
not present on 1643 AMS.
