HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER

AND M13 MULTIPLEXER

PROPRIETARY AND CONFIDENTIAL

• Provides optional automatic insertion of far end receive failure (FERF) on

detection of loss of signal (LOS), out of frame (OOF), alarm indication signal

(AIS) or red alarm condition.

• 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 (FEBE)

events.

• Supports insertion of 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 and interrupt-driven operation.

• Provides programmable pseudo-random test sequence generation (up to 232-1

bit length sequences conforming to ITU-T O.151 standards) or any repeating

pattern up to 32 bits. The test pattern can be framed or unframed. Diagnostic

abilities include single bit error insertion or error insertion at bit error rates

ranging from 10-1 to 10-7.

M23 Multiplexer Section:

• Multiplexes 7 DS2 bit streams into a single M23 format DS3 bit stream.

• Performs required bit stuffing/destuffing including generation and interpretation of

C-bits.

• Includes required FIFO buffers for rate adaptation in the multiplex path.

• Allows insertion and detection of per DS2 payload loopback requests encoded in

the C-bits to be activated under microprocessor control.

• Internally generates a DS2 clock for use in integrated M13 or C-bit parity

multiplex applications. Alternatively accepts external DS2 clock reference.

• Allows per DS2 alarm indication signal (AIS) to be activated or cleared for either

direction under microprocessor control.

• Allows DS2 alarm indication signal (AIS) to be activated or cleared in the

demultiplex direction automatically upon loss of DS3 frame alignment or signal.

• Supports C-bit parity DS3 format.
