UK Area Code information for 0131
Edinburgh Area Code Allocation
Ofcom has allocated the 0131 area code to service Edinburgh and the surrounding area on at least 20 exchanges. The 0131 range is actually made up of 8 smaller number blocks starting; 01310, 01311, 01312, 01313, 01314, 01315, 01316 and 01317. These additional ranges allow numbers to be associated with Edinburgh but are not necessarily numbers connected to physical phones in properties in the Edinburgh area.Edinburgh Exchange Information

Companies Operating 0131 Numbers
The following list of companies have been licensed by Ofcom to operate geogrpahic numbers in Edinburgh. It is worth noting that most, although not all, providers other than BT (or possibly Virgin, Kingston Telecom, et al) are are likely not operating fixed line services to this locale and, as such, should not be seen as providing a legitimate fixed line geogrpahic service to Edinburgh;
Broadband Connectivity Type Definitions
Different telephone exchanges have different broadband connectivity depending on their geographic location, the consumers they serve (demand and composition of those consumers) and the competative landscape in that locale. As a result there is a mix of services and related performance which BT classify as follows;
Fixed Rate
There for three fixed rate lines; 512Kbps, 1Mbps and 2Mbps. As with IPStream 500, 1000 and 2000, these have an upstream capped at 288Kbps. Note that all of the other WBC products apart from these are strictly rate adaptive (like ADSL Max).
WBC Fixed Rate
Wholesale Broadband Connect (WBC) offers high-speed, high-performance broadband services.
ADSL Max
BT's original ADSL2+ wholesale product with an option of an upstream cap at 448Kbps or no cap at all. ADSL2+ can achieve up to 1Mbps upstream.
WBC ADSL 2+
ADSL2+ (also known as 21CN (21st Century Network) and WBC (Wholesale Broadband Connect) is a high speed broadband service which offers download speeds of up to 24Mbs and upload speeds of up to 1Mbs.
WBC ADSL 2+ Annex M
ADSL2+ Annex M offers up to 2.5Mbps upstream in the UK. This product is used by many businesses who could previously only find this level of upstream bandwidth with SDSL. Note that there is no option for a capped upstream with this product.
FTTC Range A (Clean)
FTTC Range A is a range where the circuits are deemed to be free of any copper line faults, and any local wiring issues (in a customer's premises). This range is often very wide for both upload and download, and does beg the question of why a copper line fault may exist without being fixed.
FTTC Range B (Impacted)
FTTC Range B is a range where circuits may have copper faults and/or internal wiring issues at a customer's site. The term impacted could be useful, as sometimes crosstalk is mentioned as something that impacts on line speeds, but there is no official word from BT on whether either Range A or Range B take into account the effects of crosstalk.
FTTP On Demand
Fiber to the home (FTTH), also called "fiber to the premises" (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access. FTTH dramatically increases the connection speeds available to computer users compared with technologies now used in most places.
