Configurable, multi-channel, payload processor for aligning SONET virtual tributaries
(VTs) or SDH tributary units (TUs) in an STS-48/STM-16 or four STS-12/STM-4 byte
serial data streams.
Integrates 4 x STS-12/STM-4 VT level payload processors, 2 x ingress and egress STS-
1/STM-0 granular time slot interchanges, 8 x ingress and egress STS-12/STM-4 VT level
time switches and an STS-192/STM-64 VT level space switch (cross bar).
Integrated crossbar allows for hair-pinning and OC-48 add-drop mux (ADM) functionality.
Four TUPP 2488s may be used in parallel to support STS-192/STM-64 applications.
Can be setup to operate in 1 of four applications:
o Hair-pinning (from line ingress to line egress)
o OC-48 ADM with internal crossbar
o NxOC-48 ADM with external crossbar (internal crossbar is bypassed)
o Payload Processing Configuration
In hair-pinning applications from line ingress to line egress, provides an internal VT
granularity Time:Space:Time switch fabric.
In OC-48 ADM applications, the internal VT level time switches and crossbar can be used
with external time switches (e.g. PM8610 SBS or PM8611 SBS-Lite devices) on the system
side to implement a VT granularity Time:Space:Time switch and provide 2488.32 Mbit/s
full-duplex switching.
In NxOC-48 ADM, VT level cross connect applications, internal crossbar is bypassed. An
external crossbar (e.g. PM8620 NSE device) and external time switches on the system side
can be used instead in conjunction with the internal VT level time switches.
Supports 1:2 multicast for drop and continue.
Provides independent time-slot interchange blocks on the line side ingress and egress
interfaces to allow arbitrary arrangement of time-slots at STS-1/STM-0 granularity. Time-
slot interchange blocks are independently provided for working and protect links.
On the line side, provides a 4 x 8-bit or 32-bit 77.76 MHz TelecomBus interface for direct
connection to the PM5315 SPECTRA2488. This interface is referred to as the Ingress and
Egress Byte-Wide TelecomBus Interface in this document.
Robust signal integrity over high speed links using PMC-Sierra’s RASIO™ CML I/O.
Alternatively on the line side, provides redundant working and protect ingress and egress
Serial RASIO™ CML links. This interface is referred to as the Line Ingress and Egress
Serial RASIO™ CML Interface in this document. These links are configurable as either:
o 4 x STS-12/STM-4 622.08 MHz SONET/SDH Framed Interfaces, or
o 4 x STS-12/STM-4 777.6 MHz 8B/10B Encoded TelecomBus Interfaces, or
