CHAPTER II, SECTION 6 Peg count meters, used to accumulate tele- ‘phone traffic data, were not received until mid- May 1958. Although the peak traffic for this Operation was probably one month earlier, enough information has been compiled since May to evaluate the telephone system in relation to this and future Operations. The maxi- mum number of calls per week occurred during the week ending 2 June, with 87,925 calls, or approximately 12,560 calls per day. Studies indicated that there was sufficient dial equipment at Elmer to provide a grade of service exceeding commercial standards, even though requirements increased as much as 50%. As noted previously, studies indicated a shortage of cable pairs to Yvonne and Janet. Although the Elmer office had a capability of 686 lines, the maximum number used was 582, leaving approximately 20% of the exchange lines unused during Operation HARDTACK. There were practically no restrictions on requests for service, and lines per User exceeded normal commercial] requirements. Traffic studies made at the Nan PBX during the peak of the Operation indicated the need for at least one additional PBX position. The two operators working the board were unable to handle the traffic efficiently during peak usage periods. Due to the size of the operating room, another position could not have been added even if available. The situation was further aggravated by the amountoftraffic that could be passed automatically to Nan from Elmer through the Tropospheric System, only to be delayed by the limited capability of the manual PBX board at Nan. The Honolulu radio telephonecircuit trans- mitting and receiving equipment was maintained by TG 7.2, and toll service was handled through H&N telephone operators at Elmer. This circuit was below commercial grade, with the circuit unsatisfactory 25% of the time and completely inoperative 10% of the time. Calls were prolonged because of the constant speech repetition that was necessary due to low and fluctuating audio levels. Also, the single circuit proved in- adequate for the quantity of scheduled traffic. 2, e (Neg. No. W-938-8) Figure No. 2-158. Radio Shop, Building 204 — Nan. Page 315
