COMET
Combined E1/T1/J1 Transceiver/Framer
RECEIVE
• Provides single-rail digital PCM and
signaling outputs for 1.544 Mbit/s,
2.048 Mbit/s, 4.096 Mbit/s, or
8.192 Mbit/s backplane buses.
• Guaranteed signal recovery of up to
-36 dB at 1024 kHz (E1) and 772 kHz
(T1/J1) under production test
conditions (VDD = 3.069 V, 25 °C)
using PIC-22 gauge cable emulation.
• Frames to a G.704 E1 signal.
• Frames to a JT-G704 J1 signal.
• Frames to a DSX/DS-1 signal in D4,
SF, ESF, or SLC96 formats.
• Accommodates up to 0.4 UI peak-topeak, high frequency jitter as required
by AT&T TR 62411.
• Supports line and path performance
monitoring to AT&T and ANSI
specifications and ITU-T
recommendations.
• Detects both programmable in-band
loopback activate and deactivate code
sequences received in the DS1/E1
data stream.
• Supports transfer of transmitted PCM
and signaling data from 1.544 Mbit/s,
2.048 Mbit/s, 4.096 Mbit/s, or
8.192 Mbit/s backplane buses.
• Supports tristate line outputs.
• Generates DSX-1 T1 shorthaul- and
T1 longhaul-compatible pulses with
programmable pulse shape to AT&T
and ANSI specifications and ITU-T
recommendations.
• Generates G.703 E1 pulses.
• Detects violations of the ANSI T1.403
12.5% pulse density rule over a
moving 192-bit window.
• Allows insertion of in-band loopback
code sequences.
• Supports transmission of the Alarm
Indication Signal (AIS) or the yellow
alarm signal in all formats.
• Provides a FIFO for jitter attenuation in
the transmit path.
• Complies to all jitter attenuation, jitter
transfer and residual jitter
specifications required by AT&T TR
62411 and ETSI TBR12/13.
