Construction commenced in 1953 under the guise of building an underground railway and opened in September 1957 at a cost of £4 million. It was located nominally on Newhall St. However its network of tunnels extended from at least the Jewellery Quarter to Southside.It originally formed one of a network of 18 Zone Switching Centres within the United Kingdom (UK) telephone system that provided trunk switching facilities within its own charge group and to Group Switching Centres (GSC) within an area broadly comprising the West Midlands and central Wales. The exchange formed part of the trunk mechanisation plan commenced in 1939 to permit operators from originating GSCs to dial through to a distant UK subscriber without requiring further operator intervention. Later, it was additionally used to switch subscriber dialled trunk calls after its introduction at Bristol in 1958. It was subsequently augmented and superseded by a Transit Switching Centre (TSC) equipped with a crossbar switching system (TXK4) which formed part of the Transit Network. It parented two of the first three GSCs at Worcester and Wolverhampton to go-live when the transit network was inaugurated in 1971 which eventually provided universal UK automatic subscriber dialling and was completed in 1979.The Anchor telephone exchange tunnels are still used to house communication cables. They have been updated with firebreak compartments and hazardous asbestos has been removed. They are continually pumped out because of the city's rising water table.The exchange took its name from the hallmark of Birmingham Assay Office, which depicts an anchor."@en }
