The eleven BT Telephone Exchanges (and nine former) in the Sudbury (01787) telephone area
The first place to get a phone service in (what became) the Sudbury group was the village of Earls Colne in 1902. Sible Hedingham and the town of Halstead followed on the same day in 1903. (The fact that these Essex exchanges ended up grouped with Sudbury – in Suffolk – was to cause controversy in later years: see Halstead.) In Sudbury itself, the council and traders feared the town was being left behind and lobbied for a telephone service which finally arrived on 26 April 1905. Portway’s ironmongers were so keen to get in on the act that they’d been advertising their phone number – Sudbury 27 – in the local papers for two months before the exchange even opened. The manual switchboard was in the post office on Market Hill, seen here on the right. It stayed there for just under seven years, connecting its last call on the morning of Sunday 10 March 1912.

Boxford former ATE

The former Boxford telephone exchange stands in Stone Street Road, Boxford CO10 5NP. It came into service as an RAX5 on 2 August 1932 replacing a manual exchange opened on 2 February 1925. It ceased operation around 1973 when the current exchange was opened, all lines becoming Boxford 210xxx numbers. A plan in 1993 to build affordable homes on the site was scuppered when an adjoining owner refused to sell the necessary land, so it survives as the parish council office.
Its dialling code was 078 78.

Halstead ATE

It came into service in the early 1960s, the first (manual) exchange in Halstead having been opened in the old post office on the corner of the High Street and Chapel Street on 14 October 1903 with 14 subscribers. In 1965 the MP Peter Kirk protested in the Commons about Halstead, Great Yeldham and Earls Colne exchanges (which are in Essex) being in the Sudbury (Suffolk) group rather than the Braintree group. He claimed they had no connection with Suffolk and it meant calls to London were twice as expensive.The Assistant Postmaster General Joseph Slater said nothing could done. And it wasn’t.
In 1980, the four-digit Halstead numbers were prefixed with 47.
The telephone code for this exchange is 01787-47.

The former manual Hedingham telephone exchange, seen here in 1953, was at 99 Swan Street, Sible Hedingham CO9 3HP.

The switchboard was in the ground floor room seen on the left. The day operator was a Miss Hale and the caretaker operator WT Pryke, who’d lost a leg in the Great War. After closure it became a branch of Barclays Bank and is now (2022) a fast food outlet.
