It is a Plessey 7P a version made by their Portuguese subsidiary AEP: Automatica Electrica Portuguesa (Portuguese subsidiary of ATM Ltd) ATE: Automatic Telephone & Electric (ATM was renamed ATE in 1936). ATM: Automatic Telephone Manufacturing Company. Plessey then took over ATE Ltd in the 1960's . Very similar to 706 circuit used on PAXs in the UK.
