Features
- Configurable, multi-channel, payload processor for aligning SONET virtual tributaries (VTs) or SDH tributary units (TUs) in an STS-48/STM-16 or four STS-12/STM-4 byte serial data streams.
- Integrates 4 x STS-12/STM-4 VT level payload processors, 2 x ingress and egress STS-1/STM-0 granular time slot interchanges, 8 x ingress and egress STS-12/STM-4 VT level time switches, and an STS-192/STM-64 VT level space switch (cross bar).
- Integrated crossbar allows for hair-pinning and OC-48 Add Drop Mux (ADM) functionality.
- Can be set up to operate in one of four applications:
- Hair-pinning (from line ingress to line egress).
- OC-48 ADM with internal crossbar.
- NxOC-48 ADM with external crossbar (internal crossbar is bypassed).
- Payload Processing Only Configuration.
- On the line side, provides a 4 x 8-bit or 32-bit 77.76 MHz parallel TelcomBus interface as well as redundant working and protect ingress and egress Serial CML links. Links are configurable as:
- 4 x STS-12/STM-4 622.08 MHz SONET/SDH framed interfaces.
- 4 x STS-12/STM-4 777.6 MHz 8B/10B encoded TelecomBus interfaces.
- 1 x STS-48/STM-16 2.488 GHz SONET/SDH framed interface. This is tied to one link and the other three links are unused.
- On the system side, provides redundant working and protect ingress and egress serial CML links. Links are configurable as:
- 8 x STS-12/STM-4 622.08 MHz SONET/SDH framed interfaces.
- 8 x STS-12/STM-4 777.6 MHz 8B/10B encoded Telecom Bus interfaces.
- Independently configurable line and system inteface rates.
- Provides optional PRBS generation and monitoring features for CML off-line link verification.
- Supports contiguously concatenated payloads (STS-3c, STS-12c/AU-4-4c, STS-48c/AU-4-16c).

- On the ingress path, provides optional SDH payload conversion of:
- AU3/VC3/C3 to an AU4/VC4/TUG3/TU3/VC3/C3.
- AU3/VC3/TUG2 to AU4/VC4/TUG3/TUG2.
- AU4/VC4/TUG3/TU3/VC3/C3 to AU3/VC3/C3.
- AU4/VC4/TUG3/TUG2 to AU3/VC3/TUG2.
- On the egress path, provides optional SDH payload conversion of an AU3/VC3/C3 to an AU4/VC4/TUG3/TU3/VC3/C3.
- Supports any legal mix of VT1.5, VT2, VT3, VT6, TU11, TU12, TU2, or TU3 tributaries. Each VT group or TUG2 can be configured to carry one of four tributary types. TUG2s can be multiplexed into VC3s or TUG3s. Each TUG3 can also be configured to carry a single TU3.
- Supports 16-byte or 64-byte format tributary path trace messages (tributary trail trace identifiers).
- BIP error performance is monitored using Errored Seconds (ES) and Severely Errored Second (SES) counts and thresholds using programmable time windows.
- Errored Seconds (ES) and Severely Errored Second (SES) thresholding can be used to trigger degrade and fail indications which can optionally generate interrupts.
- Supports High Order path termination for any legal mix of STS-1/AU-3, STS-3c/AU-4, STS-12c/AU-4-4c, and STS-48c/AU-4-16c.
- Provides dedicated interfaces to optionally extract the entire high/low order path overhead from the ingress data for external processing and provides a dedicated interface to optionally insert the high order path overhead into the egress data stream.
- Provides a standard 5 signal IEEE 1149.1 JTAG test port for boundary scan test purposes.
- Implemented in 1.2 V core and 2.5/3.3 V I/O 0.13µm CMOS technology. I/Os are either 2.5 V or configurable as either 2.5 V or 3.3 V.
- 580-ball UBGA package (35 mm x 35 mm).
