Hi
To support the new ReTX G.998.4 being adopted by some of the main euro
isp's at the moment # bReTXEnable may be needed to be added to
dsl_control?
Also in drv_dsl_cpe_api.c bRetTXEnable = DSL_TRUE; to added ?
To avoid issues with RTX_FORCED parameter
{{{
++pContext->lineFeatureDataCfg[DSL_UPSTREAM].bRetTXEnable = DSL_TRUE;
++ pContext->lineFeatureDataCfg[DSL_DOWNSTREAM].bRetXEnable = DSL_TRUE;
}}}
Currently any vrx based modems will have issues tying to connect to a
G.INP profiled line with RTX_FORCED parameter.
{{{
1.1.13 Retransmission Mode (RTX_MODE)
The RTX_MODE is a configuration parameter used to control activation of
retransmission during initialization.
This parameter has 4 valid values:
0: RTX_FORBIDDEN: ITU-T G.998.4 retransmission not allowed.
1: RTX_PREFERRED: ITU-T G.998.4 retransmission is preferred by the
operator.
(i.e., if ITU-T G.998.4 RTX capability is supported by both XTU's, the
XTU's shall select ITU-T G.998.4 operation for this direction).
2: RTX_FORCED: Force the use of the ITU-T G.998.4 retransmission.
(i.e., if ITU-T G.998.4 RTX capability in this direction is not supported
by both XTU's or not selected by the XTU's, an initialization failure
shall result).
NOTE – Due to the optionality of ITU-T G.998.4 retransmission in upstream
direction, the use of RTX_FORCED in upstream may lead to initialization
failure, even if the XTU is supporting ITU-T G.998.4 (in downstream).
3: RTX_TESTMODE: Force the use of the ITU-T G.998.4 retransmission in the
test mode described in clause 10.4.
(i.e., if ITU-T G.998.4 RTX capability is not supported by both XTU's or
not selected by the XTU's, an initialization failure shall result).
}}}
Thanks as always to John for continued work with lantiq based devices!
