HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER

AND M13 MULTIPLEXER

PROPRIETARY AND CONFIDENTIAL

• Provides a FIFO buffer for jitter attenuation in the transmitter.

Each one of three SONET/SDH Tributary Path Processing Sections:

• Interfaces with a byte wide Telecom Add/Drop bus, interfacing directly with the

PM5362 TUPP-PLUS and PM5342 SPECTRA-155 at 19.44 MHz.

• Seamlessly interfaces with a 77.76 MHz Drop bus. Interfaces to a 77.76 MHz

Add bus with minimal external logic.

• 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 tributary pointers.

• Optionally frames to the H4 byte in the path overhead to determine tributary

multi-frame boundaries and generates change of loss-of-frame status interrupts.

• Detects loss of pointer (LOP) and re-acquisition for each tributary and optionally

generates interrupts.

• Detects tributary path alarm indication signal (AIS) and return to normal state for

each tributary and optionally generates interrupts

• Detects tributary elastic store underflow and overflow and optionally generates

interrupts.

• Provides individual tributary path signal label register that hold the expected label

and detects tributary path signal label mismatch alarms (PSLM) and return to

matched state for each tributary and optionally generates interrupts.

• Detects tributary path signal label unstable alarms (PSLU) and return to stable

state for each tributary and optionally generates interrupts.

• Detects assertion and removal of tributary extended remote defect indications

(RDI) for each tributary and optionally generates interrupts.

• Calculates and compares the tributary path BIP-2 error detection code for each

tributary and configurable to accumulate the BIP-2 errors on block or bit basis in

internal registers.

• Allows insertion of all-zeros or all-ones tributary idle code with unequipped

indication and valid pointer into any tributary under software control.

• Allows software to force the AIS insertion on a per tributary basis.
