COMBINED E1/T1 TRANSCEIVER

1 FEATURES

• Monolithic device which integrates software selectable full-featured T1 and

E1 framers and T1 and E1 short haul and long haul line interfaces.

• Meets or exceeds T1 and E1 shorthaul and longhaul network access

specifications including ANSI T1.102, T1.403, T1.408, AT&T TR 62411, ITU-T

G.703, G.704 as well as ETSI 300-011, CTR-4, CTR-12 and CTR-13.

• Provides encoding and decoding of B8ZS, HDB3 and AMI line codes.

• Provides receive equalization, clock recovery and line performance

monitoring.

• Provides transmit jitter attenuation and digitally programmable long haul and

short haul line build out.

• Provides on-board programmable binary sequence generators and detectors

for error testing including support for patterns recommended in ITU-T O.151.

• Provides three full-featured HDLC controllers, each with 128-byte transmit

and receive FIFO buffers.

• Automatically generates and transmits DS-1 performance report messages to

ANSI T1.231 and ANSI T1.408 specifications.

• Compatible with Mitel ST®-bus, AT&T CHI® and MVIP PCM backplanes,

supporting rates of 1.544 Mbit/s, 2.048 Mbit/s, 4.096 Mbit/s, and 8.192 Mbit/s.

Up to four COMET devices may be byte-interleaved on a single backplane

with no external circuitry.

• Supports NxDS0 fractional bandwidth backplane.

• Provides an 8-bit microprocessor bus interface for configuration, control, and

status monitoring.

• Uses line rate system clock.

• Provides a IEEE P1149.1 (JTAG) compliant test access port (TAP) and

controller for boundary scan test.

• Implemented in a low power 5 V tolerant +3.3 V CMOS technology.
