HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
· 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 128-byte deep FIFO buffer with programmable interrupt
threshold. Supports polled or interrupt-driven operation. Selectable none,
one or two address match detection on first byte of received packet.
· Programmable pseudo-random test-sequence detection–(up to 232 -1 bit
length patterns conforming to ITU-T O.151 standards) and analysis features.
DS3 Transmit 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 B3ZS encoding.
· Generates an B3Zs encoded 100… repeating pattern to aid in pulse mask
testing.
· Inserts far end receive failure (FERF), the DS3 alarm indication signal (AIS)
and the idle signal when enabled by internal register bits.
· 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
