M13 MULTIPLEXER

parity mode operation, up to 16,383 C-bit parity error events per second, and

16,383 far end block error (FEBE) events per second.

• Detects and validates bit-oriented codes in the C-bit parity far end alarm and

control channel.

• Terminates the C-bit parity path maintenance data link with an integral HDLC

receiver having a 4-byte deep FIFO buffer. Supports polled, interrupt-driven

or DMA access.

• Optionally extracts the C-bit parity mode path maintenance data link signal

and serializes it at 28.2 kbit/s.

• Extracts the X, P, M, F, C and stuff opportunity bits and serializes them at

526 kbit/s on a time division multiplex signal.

Each DS3 transmit framer section:

• Provides the overhead bit insertion for a DS3 stream.

• Provides a bit serial clock and data interface, and allows the M-frame

boundary and/or the overhead bit positions to be located via an external

interface

• Provides optional insertion of the X, P, M, F, C, and stuff opportunity bits via a

526 kbit/s serial interface.

• Provides B3ZS encoding.

• Inserts far end receive failure (FERF), the DS3 alarm indication signal (AIS)

and the idle signal when enabled by external inputs, or internal register bits.

• Provides diagnostic features to allow the generation of line code violation

error events, parity error events, framing bit error events, and when enabled

for the C-bit parity application, C-bit parity error events, and far end block

error events.

• Inserts bit-oriented codes in the C-bit parity far end alarm and control

channel.

• Optionally inserts the C-bit parity path maintenance data link with an integral

HDLC transmitter. Supports polled, interrupt-driven, or DMA access.
