E1 FRAMER/TRANSCEIVER
Indicates the reception of remote alarm and remote multiframe alarm.
Indicates the reception of alarm indication signal (AIS) and time slot 16 AIS.
•
•
•
Declares RED and AIS alarms using Q.516 recommended integration
periods.
Provides an HDLC/LAPD 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 0 of non-frame alignment signal frames (4 kbit/s - 20
kbit/s).
Provides a two-frame elastic store buffer for jitter and wander attenuation that
performs controlled slips and indicates slip occurrence and direction.
•
•
Provides channel associated signalling extraction, with optional data
inversion, programmable idle code substitution, and up to 3 multiframes of
signalling debounce on a per-timeslot basis.
Provides trunk conditioning which forces programmable trouble code
substitution and signalling conditioning on all timeslots or on selected
timeslots.
•
Optionally provides dual rail digital PCM output signals to allow BPV
transparency. Also supports unframed mode.
•
•
Supports transfer of received PCM and signalling data to 2048 kbit/s
backplane buses.
The transmitter section:
Supports transfer of transmitted PCM and signalling data from 2048 kbit/s
backplane buses.
•
•
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.
Optionally accepts dual rail digital PCM inputs to allow BPV transparency.
Also supports unframed mode.
•
•
Provides channel associated signalling insertion, programmable idle code
substitution, digital milliwatt code substitution, and data inversion on a per
timeslot basis.
