PM4354 COMET-QUAD

• Provides diagnostic, line and per-DS0

payload loopbacks.

• Extracts up to three HDLC links to an

H-MVIP Bus to support the D-channel,

for ISDN Primary Rate Interfaces, and

the C-channels, for V5.1/V5.2

interfaces. Detects the V5.2 link

identification signal.

TRANSMITTER

• Generates DSX-1 shorthaul and DS-1

longhaul pulses with programmable

pulse shape compatible with AT&T,

ANSI and ITU requirements.

• Generates E1 pulses compliant to

G.703 recommendations.

• Provides line outputs that are current

limited and may be tristated for

protection or in redundant applications.

• Provides a digital phase locked loop

for generation of a low jitter transmit

clock complying with all jitter

attenuation, jitter transfer and residual

jitter specifications of AT&T TR 62411

and ETSI CTR 12 and CTR 13.

• Provides a FIFO buffer for jitter

attenuation and rate conversion in the

transmit path.

• Supports unframed mode and framing

bit, CRC, or data link by-pass.

• Allows insertion of framed or unframed

in-band loopback code sequences.

• Allows insertion of a data link in ESF

mode. Optionally inserts a datalink in

the E1 national use bits.

• Inserts, from an H-MVIP bus, up to

three HDLC links to support the D-

channel, for ISDN Primary Rate

Interfaces, and the C-channels, for

V5.1/V5.2 interfaces.

• Transmits TTC JT-G704 multiframe

formatted J1 signals. Supports the

alternate ESF CRC-6 calculation for

Japanese applications.

• Supports transmission of the alarm

indication signal (AIS) and the yellow

alarm signal. Supports Japanese

yellow alarm generation.

• Provides ESF bit-oriented code

generation.
