40 Gbit/s Transport Switching Element
Preliminary PM5372 TSE
APPLICATIONS
In combination with the PM5310 TBS
(TelecomBus Serializer and Time-Space
switching stage), the PM5315
SPECTRA-2488, the PM5316
SPECTRA-4X155, and the PM7390
S/UNI-MACH48, the PM5372 TSE
supports a variety of flexible Layer 1 /
Layer 2 architectures. These architec-
tures can implement features commonly
found in DCS, ADM, and multi-service
switch/router equipment.
The PM5372 TSE provides the function-
ality that enables networking equipment
to:
• Connect to (multiple) SONET rings.
• Participate in mesh-connected
architectures.
• Serve as SONET-connected terminal
multiplexers.
• Groom traffic at STS-1/AU-3
granularity.
• Support channelization of OC-
3/12/48/192 line rates.
• Support concatenated lines rates
including STS-1 (DS-3), STS-3c, STS-
12c, STS-48c and STS-192c.
• Support add, drop, and drop-and-
continue.
• Support UPSR, 2-BLSR, 4-BLSR, and
1+1 or 1:N APS.
• Support mesh-based APS systems.
