Features
- A configurable, multi-channel, payload processor for alignment of SONET virtual tributaries (VTs) or SDH tributary units (TUs). Configurable to process any legal mix of tributaries.
- Provides independently configurable AU3/AU4 frame format on incoming and outgoing directions.
- Compensates for pleisiochronous relationships between incoming and outgoing higher level (STS-1, AU4, AU3) synchronous payload envelope frame rates through processing of the lower level (VT6, VT3, VT2, VT1.5, TU3, TU2, TU12, or TU11) tributary pointers.
- Provides for multiframe synchronization or ring closure at the headend node in a SONET/SDH ring.
- Optionally frames to the H4 byte in the path overhead to determine tributary multiframe boundaries.
- Inserts valid pointers, and all-zeros transport overhead bytes on the outgoing stream with valid "TelecomBus" control signals when configured to operate in locked mode.
- Operates in conjunction with the PM5343 STXC, the PM5344 SPTX and the PM5371 TUDX to provide a complete SONET/SDH ADM from Photonics down to the Tributary mapper.
- Independently configurable incoming and outgoing interfaces that operate in byte interface mode using a 19.44 MHz clock or in nibble interface mode using a 38.88 MHz clock.
- Provides a generic 8-bit microprocessor bus interface and a standard 5 signal IEEE P1149.1 JTAG test port.
- Low power, +5 Volt, CMOS technology, TTL compatible inputs and outputs.
- Available in a 160-pin PQFP package (28x28 mm).
- Per Tributary Functions
- Detects loss of pointer and re-acquisition.
- Extracts and serializes the entire tributary path overhead of each tributary.
- Detects tributary elastic store underflow and overflow errors.
- Stores and processes 16-byte or 64-byte format tributary path trace messages (tributary trail trace identifiers). Detects tributary path trace mismatch (TIM) and unstable (TIU) alarms.
- Extracts tributary path signal label into internal registers and detects change of tributary path signal label events (COPSL) for each tributary. Detects tributary path signal label mismatch (PLSM) and unstable (PSLU) alarms.
- Detects tributary unequipped defect (UNEQ), tributary path defect indication (PDI-V) and the assertion and removal of tributary extended remote defect indications (RDI).
- Extracts and stores the tributary size (SS) bits.
- Calculates and compares the tributary path BIP-2 error detection code. Accumulates the BIP-2 errors and tributary path far end block errors (FEBE), on a block or bit basis.
- Supports in-band error reporting by updating the FEBE, RDI and auxiliary RDI bits in the V5 byte (G1 in TU3) with the status of the incoming stream.
- Optionally generates tributary path AIS on the detection of loss of pointer, loss of tributary multiframe, trace identifier unstable, trace identifier mismatch, signal label unstable and/or signal label mismatch. Also allows software to force AIS insertion.
- Under software control, allows insertion of all-zeros or all-ones tributary idle code with unequipped indication.
