§ Mr. Onslowasked the Postmaster-General what proportion of subscriber trunk dialling telephone calls from the 421W Guildford telephone area failed as a result of plant defects during the years 1966 and 1967, respectively.
§ Mr. Joseph Slater5.8 per cent. and 4.3 per cent., respectively. Improvement has been achieved by intensifying maintenance. On some trunk calls during the busier periods of the day lines are engaged, but the likelihood of this will lessen progressively during the next few months, as additional equipment is brought into service.
