§ 35. Sir B. Jannerasked the Postmaster-General whether he will arrange for pips to give a three-minute time signal on the subscriber trunk dialling system for all trunk calls, and thus assist subscribers in regulating the length of time of such calls.
§ Mr. Joseph SlaterNo, Subscriber-dialled trunk calls are charged for in units of only 2d. (3d. from coinboxes) and the three-minute minimum charge period, which is a feature of operator-controlled trunk calls, does not apply.
