Data Transmission
Characteristics
This transceiver is intended for use on connections on Power
Line Carrier Systems on point-to-point, mesh, hierarchical or
star topology. The principal characteristics of the Transceiver
are as follows:
A. Duplex mode of operation.
B. Channel separation by echo cancellation techniques;
C. Quadrature Amplitude Modulation (QAM) for each channel
with synchronous line transmission at selectable symbol rates
of 2400, 3000, 3200, 3429 symbols/s.
D. Depending on the Power Line Conditions, the following
standard Synchronous channel data signaling rates can be
achieved:
- 62.400 bit/s;
- 57.6 00 bit/s;
- 52.800 bit/s;
- 48.000 bit/s;
- 43.2 00 bit/s;
- 38.400 bit/s;
- 33 600 bit/s;
- 31 200 bit/s;
- 28 800 bit/s;
- 26 400 bit/s;
- 24 000 bit/s;
- 21 600 bit/s;
- 19 200 bit/s;
- 16 800 bit/s;
- 14 400 bit/s;
- 12 000 bit/s;
- 9600 bit/s;
- 7200 bit/s;
- 4800 bit/s;
- 2400 bit/s;
E. Trellis coding for all data signaling rates;
F. Adaptive techniques that enable the modem to achieve
close to the maximum data signaling rate the channel can
support on each connection;
G. Exchange of rate sequences during start-up to establish
the data signaling rate.
H. Modulation : It is an Adaptive Trellis Code Modulation with
Multidimensional Error Correction resulting in fractional bits
per symbol, from 4 QAM to 1024 QAM, depending on the
Power Line Conditions and Bandwidth available.
