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.
