Our methods and procedures people have made a detailed atudy of this problast in aa attempt to adjust the HTDXA sreteisrs to the easential atnlaaau However, we have concluded that the proper course i s to adept ACP 127C procedure outright on this system. There are two reasons for this. 5. tat first reason is tho necessity to ensure that traffic will continue to flow even if the CARP relay centre ia out of action, tat only alternative to the CAItr relay centre is one of the other military relay centres ia Canada, tiniest ACP 127C procedure i» employed oa HTLRA, i t will be quite impossible to pat* this traffic ia aa emergency through teat other surviving relay centre. The second reason is that the diff< ia irooeduvea i t already causing significant difficulty in training tad canning, and this i t aggravated when the mm relay operation occurs at CAEP, which ia also tat Urinary Relay Centre In the Army network. 6. I understand that It ia the long tarn plan ex osrs to and rationalise jwaincci'it and Service* facilities.
