SONET/SDH STS-48/STM-16 Framer/Pointer Processor

Part Number S4805CBI11, Revision 1.5, January 2003

• SONET/SDH Mux/Demux, Transport Overhead Terminating

Transceiver and Pointer Processors for STS-48/STM-16 and

up to 4 x STS-12/STM-4 or 16 x STS-3/STM-1s.

• Serial STS-12/STM-4 and STS-3/STM-1 interfaces.

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

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

eration device.

• Built-in 192x48 cross-connects for STS-1 level cross-connec-

tion or add/drop, in both Mux and Demux directions.

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

-1995 standards.

Multiplex Direction:

• Supports parallel STS-48/STM-16 or serial 4xSTS-12/STM-4

or serial 16xSTS-3/STM-1 inputs.

• Provides a single STS-48/STM-16 output.

• Pointer Processors for all valid input combinations of STS-48c/

AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU-4, or STS-1/AU-3

signals.

• Non-intrusive TOH monitoring for all inputs: STS-48, 4xSTS-12

or 16xSTS-3.

• Provisionable pointer processor bypass available for STS-48 to

STS-48 operation (through-timing). Both a full bypass (no

frame regeneration) as well as a pointer processor bypass

(frame regeneration can be enabled) are provided.

• TOH can be either terminated/regenerated, or transparently

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

through-timing and pointer processor applications.

• For multiplex applications (4xSTS-12 or 16xSTS-3), the TOH

for the lower speed tributaries is passed-through in the unused

bytes of the outgoing STS-48 signal.

• STS-48 frame regeneration on output side. Provisionable pass-

through or regeneration of defined TOH bytes.

Demultiplex Direction:

• Supports a single STS-48/STM-16 input.

• Provides parallel STS-48/STM-16, serial 4xSTS-12/STM-4 or

serial 16xSTS-3/STM-1 outputs.

• Pointer Processor for all valid input combinations of STS-48c/

AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU4, or STS-1/AU-3 sig-

nals.

• Non-intrusive STS-48/STM-16 TOH monitor.

• Provisionable pointer processor bypass available for STS-48 to

STS-48 operation (through-timing). Both a full bypass (no

frame regeneration) as well as a pointer processor bypass

(frame regeneration can be enabled) are provided.

• TOH can be either terminated/regenerated, or transparently

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

through-timing and pointer processor applications.

• STS-48/STS-12/STS-3 frame regeneration on output side. Pro-

visionable pass-through or regeneration of defined TOH bytes.
