MT8910-1
Preliminary Information
9-10
TL:
A 10 kHz activation tone sourced by the
LT which is generated by sending a
continuous pattern of four +3 symbols
followed by four -3 symbols.
SL0 is a no signal condition generated
from the LT.
An LT generated signal consisting of a
framed (but not superframed),
scrambled 2B1Q signal which carries all
1s in the B-, D- and M-channels. This
signal is used to train the LT’s echo
canceller.
SL0:
SL1:
SL2:
An LT generated signal consisting of a
fully framed and superframed
scrambled 2B1Q signal which carries all
0s in the B- and D-channels with
information in the M-channel. This
signal is used to train the NT’s DFE.
An LT generated signal consisting of a
fully framed and superframed scrambled
2B1Q signal which carries information in
all the B-, D- and M-channels.
