Switch Fabric Subsystem
The sixteen MSU-Lite blocks and one CCB block in TUPP 2488 form the switch fabric
subsystem. These can be used as:
•
•
•
•
The Switch Fabric supports eight STS-12/STM-4 input streams. Any SONET/SDH VT/TU up
to STS-1/STM-0 can be switched. Each of the ingress STS-12/STM-4 streams is bi-cast into the
fabric. There are eight MSU-Lite blocks in the ingress path of TUPP 2488 (two per STS-
12/STM-4 slice) and eight MSU-Lite blocks in the egress path (two per STS-12/STM-4 slice) of
TUPP 2488. The MSU-Lite block is a time switch.
There is one CCB block in TUPP 2488. The CCB is a space switch.
The CCB block can be bypassed and an external crossbar (e.g. NSE device) can be used instead.
The MSU-Lite blocks can form the “Time” stage of a Time:Space:Time switch fabric in
conjunction with external NSE and SBS devices.
AIS_AGGR is composed of the enabled AIS contributors reported by the RTOP: UNEQAIS,
PSLMAIS, PSLUAIS, TIUAIS, TIMAIS, LOPAIS, and LOMAIS
An internal Time:Space:Time switch fabric for use in Hairpinning applications and for use
in ADM applications where tributaries are continued.
The Time:Space stages of a Time:Space:Time fabric in the ingress (Drop) direction. The
terminating Time stage must be implemented outside the TUPP 2488 in an SBS device.
The Space:Time stages of a Time:Space:Time fabric in the egress (Add) direction. The
initial Time stage must be implemented outside the TUPP 2488 in an SBS device.
The MSU-Lites may be used with an external NSE to implement a Time:Space:Time fabric
for ADM applications.
