I have one of their early MT-V5311 modules, but it has no accessible
EEPROM, and even if it did, it would be of no use to me being
unapproved for connection to the BT Openreach network.  (BT SIN 498
specifies non-standard power profile to avoid crosstalk issues with
existing ADSL infrastructure, and I believe they regularly check the
connected modem type and firmware versions against an approved list.)

I haven't noticed the module I have asserting its TX_FAULT signal,
but then its RJ45 has never been connected to anything.
