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.
