Still not quite clear (to me at least) how this will work at the exchange…specifically the bit quoted below taken from the SOTAP blurb about the ‘engineering work’ for voice only WLR lines.
“There’ll be no engineering needed if LLU shared metallic path facility (SMPF) is already on the line – because it reuses the current LLU SMPF exchange equipment. We can still install it if there isn’t any LLU SMPF on the line (i.e. voice-only WLR lines) – we’ll just need to do some engineering work first.”
The voice-only WLR lines will need to be connected to an MSAN or DSLAM or maybe just a modem rack at the exchange in order to get a digital connection for Digital Voice.
That would make sense, ultimately the copper has to carry a basic data connection in lieu of dial tone.
Extra long rural lines could pose a challenge with data connectivity. MHC has mentioned the Scottish Highlands, but there are plenty of other places like the Lincolnshire Wolds with challenging geography that could be rather expensive to change if other delivery means like 4G aren’t feasible.
