Openreach has issued a reminder to communication providers, that when ordering an FTTC or FTTP service, they need to order the extra options for some NTE shifts and data extension kits.
What has happened and more so over the last few months is that providers are forgetting to add these options (that are included in the installation fee) to orders, resulting in confusion for retail customers when the Openreach engineer attends.
These features are optional as it allows a provider to decide based on talking to its customer what they actually want, or for the retailer to provide its own data extension service if they desire.
The standard FTTC install will result in the conversion of the current master socket into a modern NTE5 socket, with installation of the VDSL2 service specific faceplate, i.e extra RJ11 socket for connection to Openreach modem. For some customers due to the need to supply power to the Openreach modem, a current master socket location may be no good, and thus the option to move the master socket, or run a data extension (up to 30m of cable) from the master socket will be the answer.
Of course with VDSL2 if you are attempting to squeeze the most speed from the service, you will want to keep the VDSL2 cabling to a minimum. If you have had a a FTTC service installed and need to locate the modem elsewhere, then data extension kits that exist for ADSL/ADSL2+ services using twisted pair wiring should meet your needs.
If they're included in the install fee, why not just have them included in the standard installation option rather than an add on? Then the engineer can sort it all out with the customer without all this "your provider didn't tell me you needed the master socket moved" nonsense....
