PM4354 COMET-QUAD
Four Channel Combined E1/T1/J1 Transceiver/Framer
• 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.
