MULTI-PHY USER NETWORK INTERFACE

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

• Far end block errors to 1000 per second;

• Frame sync errors to 127 per second; and

• Line code violations to 8191 per second;

• Indicates the reception of remote alarm.

• Indicates the reception of alarm indication signal (AIS).

• Declares RED and AIS alarms using Q.516 recommended integration

periods.

• Provides an HDLC interface for terminating a data link. Supports polled,

interrupt-driven, or DMA servicing of the HDLC interface.

• Optionally extracts the data link from timeslot 16 (64 kbit/s), which may be

used to receive common channel signalling, or from any combination of the

national bits in timeslot 1 of non-frame alignment signal frames (4 kbit/s - 20

kbit/s).

The E1 transmitter section:

• Formats data to create a G.704 2048 kbit/s signal. Optionally inserts

signalling multiframe alignment signal. Optionally inserts CRC multiframe

structure including optional transmission of far end block errors.

• Supports transmission of the alarm indication signal (AIS), timeslot 16 AIS,

remote alarm signal or remote multiframe alarm signal.

• Provides an HDLC interface for generating a data link. Supports polled,

interrupt-driven, or DMA servicing of the HDLC interface.

• Optionally inserts the data link into timeslot 16 (64 kbit/s), which may be used

to transmit common channel signalling, or into any combination of the

national bits in timeslot 0 of non-frame alignment signal frames (4 kbit/s - 20

kbit/s).

• Supports HDB3 or AMI line code.

• Provides dual rail or single rail digital PCM output signals.
