What is a RIM and Pair Gain System?

A Large Pair Gain (RIM) is technology used by infrastructure builders to service more telephony services to an area, if you are connected to a RIM you are not connected directly to your phone exchange as there's not a complete copper path - generally this means you are only able to receive ADSL1 as this technology has been made compatible, ADSL2+ unfortunately is not.
If you are connected to a simple pair gain (PGS) system sometimes even receiving ADSL1 can be troublesome as there needs to be sufficient infrastructure to remove you from the Pair Gain System. If your order is successful you will be removed from the PGS and given a working service, this is known as line transposition, please note that transposition orders can take several weeks to be completed, but if there’s no available infrastructure they will generally be rejected within the normal 3-4 days.
