SONET/SDH STS-192/STM-64 MUX/DEMUX with Pointer Processor

Part Number S19223CBI11, Revision 1.3, May 2003

Features

• SONET/SDH Mux/Demux, Transport Overhead Terminating

Transceiver, and Pointer Processors for an STS-192/STM-64

and up to 4 x STS-48/STM-16s.

• Pointer Processors support standard SONET/SDH payload

types as well as STS-6c/9c/24c and AU-4-2c/3c/8c payload

types.

• Provisionable as SONET or SDH on a per line basis.

• Provisionable pointer processor bypass available for STS-192

to STS-192 operation (through-timing). Both a full bypass (no

frame regeneration) as well as a pointer processor bypass

(frame generation enabled) are provided.

• High-speed side supports a 622 MHz 16-bit STS-192/STM-64

interface.

• Low-speed side supports a 622 MHz 16-bit STS-192/STM-64

interface or four 622 MHz 4-bit STS-48/STM-16 interfaces.

• Cross-connects, in both directions, with STS-1 level granularity.

• Provisionable as SOH/LOH pass-through or termination/regen-

eration device.

• Compliant with ITU G.707, Bellcore GR-253, and ANSI T1.105

standards.

Multiplex Direction

• Multiplexes 4 STS-48/STM-16 tributaries into an STS-192/

STM-64 or bypass for STS-192/STM-64-to-STS-192/STM-64

connections.

• Selector for choosing high or low-speed interfaces, Deskew

Buffers, or APS inputs.

• STS-192/STM-64 framer.

• Non-Intrusive TOH Monitoring for all inputs: STS-192/STM-64

or 4x STS-48/STM-16.

• TOH can be either terminated/regenerated, or transparently

passed-through the device on a per function basis, in both

through-timing and pointer processing applications.

Demultiplex Direction

• Demultiplexes an STS-192/STM-64 into 4 STS-48/STM-16

connections or supports a bypass mode for STS-192/STM-64-

to-STS-192/STM-64 connections.

• Selector for choosing demultiplexed tributaries from high-

speed interface, low-speed interfaces or from APS inputs.

• Non-Intrusive STS-192/STM-64 Frame and TOH Monitor.

• TOH can be either terminated/regenerated, or transparently

passed-through the device on a per function basis.

• STS-192/STM-64 or 4 x STS-48/STM-16 framer(s).

• Configurable TOH Generators for STS-192/STM-64 or STS-48/

STM-16 outputs.
