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.
