2 / 18 page MV1403 1 DS3046-2.1 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.
