Operator Carrier Preselection List
Version 142 - 26th February 2010
Not for commercial publication or use.
Permanent Carrier Pre-Selection is now available from BT, which means that's smartboxes and indirect access codes may be ignored because an Other Licensed Operator can now arrange with BT for all local, national, international NTS, mobile, page and personal calls to be 'diverted' without needing to dial any extra codes (different types of call may be routed to different OLOs) . If CPS is set-up, indirect codes may still be dialled to use alternate operators or to use BT (code 1280). CPS can be supplied on single or multiline PSTN or ISDNlines.
This list is compiled from information published by Ofcom and has not been checked by Magenta Systems.
