FOUR CHANNEL COMBINED E1/T1/J1

TRANSCEIVER / FRAMER

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC. AND FOR ITS CUSTOMERS’ INTERNAL USE

•

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 TBR 12 and

TBR 13.

•

Provides a FIFO buffer for jitter attenuation and rate conversion in the transmit path.

•

Provides a two-frame payload slip buffer to allow independent backplane and line timing.

•

A pseudo-random sequence user selectable from 2

11 –1, 215 –1 or220 –1, may be inserted into or

detected from the T1 or E1 stream in either the backplane receive or backplane transmit directions.

•

Transmits G.704 basic and CRC-4 multiframe formatted E1 signals or D4, SF or ESF formatted

DSX/DS-1 signals.

•

Transmits the “Japanese Yellow” alarm. Transmits TTC JT-G704 multiframe formatted J1 signals.

Supports the alternate ESF CRC-6 calculation for Japanese applications.

•

Supports unframed mode and framing bit, CRC, or data link by-pass.

•

Provides signaling insertion, programmable idle code substitution, digital milliwatt code substitution,

and data inversion on a per channel basis.

•

Provides trunk conditioning which forces programmable trouble code substitution and signaling

conditioning on all channels or on selected channels.

•

Provides minimum ones density through Bell (bit 7), GTE or DDS zero code suppression on a per

channel basis.

•

Detects violations of the ANSI T1.403 12.5% pulse density rule over a moving 192-bit window and

optionally stuffs ones to maintain minimum ones density.

•

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.

•

Supports 4-bit codeword insertion in the E1 national use bits as specified in ETS 300 233

•

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.

•

Supports transmission of the alarm indication signal (AIS) and the Yellow alarm signal. Supports

“Japanese Yellow” alarm generation.

•

Provides ESF bit-oriented code generation.
