MV1403
PCM MACROCELL DEMONSTRATOR
The MV1403 contains 8 PCM macrocells which can be
configured so as to perform the common channel signalling
and error detection functions for a 2.048 Mbit 30 channel PCM
transmission link, operating to the appropriate CCITT
recommendations. The MV1403 also allows access to all the
macrocells individually and is implemented in GPS CMOS
technology utilising the CLA60000 series gate array, offering
high performance, low power and fast turn-round. The
following macrocells are included in the MV1403.
Timeslot Zero Transmitter - TXTSZ
Timeslot Sixteen Transmitter - TXTS16
Cyclic Redundancy Check Generator - CRCGEN
High Density Bipolar (HDB) 3 Encoder - HDB3EC
Timeslot Zero Receiver - RXTSZ
Timeslot Sixteen Receiver - RXTS16
Cyclic Redundancy Checker - CRCCHK
High Density Bipolar (HDB) 3 Decoder - HDB3DC
With the MV1403 set up to combine the internal
macrocells, two demonstration modes are available, referred
to as Transmit and Receive demonstration modes.
In Transmit demonstration mode, timeslot zero sync word
(including user data bits and optional CRC check bits), timeslot
sixteen data and 30 voice channels are combined and
transmitted as pseudo-ternary HDB3 encoded outputs. The
Transmit demonstration mode can also be set to generate
CRC multiframe data in accordance with CCITT
Recommendation G. 704.
In Receive demonstration mode, the pseudo-ternary HDB3
inputs are decoded back to NRZ form and frame
synchronisation is achieved by detection of the Frame
Alignment signal in the incoming data stream. This permits
extraction of user data bits, timeslot sixteen data and voice
channel data. An optional CRC mode generates CRC
multiframe alignment and a cyclic redundancy check is carried
out on the incoming data. In addition receive demonstration
mode generates appropriate alarms for loss of input, double
violation on the HDB3 inputs, loss of frame or CRC multiframe
alignment, detection of erroneous frame alignment word,
remote alarm received from the transmitter, and detection of a
CRC error in either submultiframe 1 or 2.
