MULTI-PHY USER NETWORK INTERFACE
• 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.
