E1 FRAMER/TRANSCEIVER
Provides trunk conditioning which forces programmable trouble code
substitution and signalling conditioning on all timeslots or on selected
timeslots.
•
Supports transmission of the alarm indication signal (AIS), timeslot 16 AIS,
remote alarm signal or remote multiframe alarm signal.
•
•
•
Provides an HDLC/LAPD 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).
Provides a digital phase locked loop for generation of a low jitter transmit
clock.
•
•
Provides a FIFO buffer for jitter attenuation and rate conversion in the
transmitter. FIFO full or empty indication allows for bit-stuffing in higher rate
multiplexing applications.
Supports HDB3 or AMI line code.
•
•
Provides analog circuitry for transmitting a G.703 compatible 2048 kbit/s
signal on a 75 coaxial line or a 120 symmetrical line. Digitally
Ω
Ω
programmable line build out is provided.
Provides dual rail or single rail digital PCM output signals.
