Dear Mr. Bowie, When Griffith and I were in Paris In January we discussed a proposal which we are exploring on behalf of our Foreign Office. I wa3 very sorry to hear that Griffith had been taken ill on his Journey to Wellington and hope he Is doing well now. In the circumstances I am addressing this follow-up letter to you, going Into some detail. Your letter of 24th June I960 referred to the same basic idea. 2. Our Foreign Offioe see the need for occasional but rapid setting up of a telex call between their London Communications Centre and Leitrim to supplement the existing leased circuit. They require such calls to be set up In an overall period of 5 rainute3 from the moment that It is demanded In either Leitrim or London. 3. The Foreign Office already have a telex Installation connected to our London automatic exchange. We do not intend that the customer should dial from his telex instrument to call our telex switchboard; in view of tho special attention that will have to be given to establio . the call wlth..y E„ time limit, we would arrange for the Foreign Office to telephone the booking to a supervisor in the telex exchange, who would p'i> . the requirement with one of our switchboard operators and ensu: that he obtained a Montreal channel expeditiously (it may becom.. a. "ssary to break down an existing call). In order to avoid a*.; lengthy explanation from our operator, ho would merely ask yours for a readily recognised number (which would be for you to suggest e.g. Montreal 9999, or Leitrim 1234). This would, we hope, be sufficient for your operator to initiate action to appropriate one of your two Montreal-Leitrim lines, normally used in conjunction with the leased circuit, to extend the call from London to .... i customer's premises at Leitrim. 4. As an overlapping opemtion, our London operator ould also obtain the Foreign Office *.lex connection on the local side of the cord circuit. We would expect the Foreign Office _-o ensure that their telex machine was not busied for any other purpose while this was going on. 5. We would expect to complete our side of the operation (London to Montreal) within 2-J minutes and would be gle . to have confirmation from you of Griffith's belle-' that your p ople could see the call through to Leitrim in a similar period of time, making a total of 5 minutes at the most. Could you al'o let me have a description of the arrangements you will be maklne, so that I can talk knowledgeably with our Foroign Office? In particular could you outline any rearrangement... of equipment at* Leitrim which may be necessary each time a tolex call of this nature Is set up, so that the Foreign Office can understand what has to be done and include it in the drill? 6. I understand that there Is a similar requi. ?nt for calls originated at Leitrim and I should be pleased tc .y*r how you would propose to-organise this. Ho very special arrangements would be necessary In London, as our operator on answering th call for the Foreign Office's London number from Montreal would simply dial that number and complete the connection. If necessary, the called number would be preceded by some code word or "Priority for ". Here again, Leitrim would tell the Foreign Office on the leased circuit that this telex call v;as about to be established and it icould be up to the Foreign Office to see that their telex line was kept clear pending receipt of the transatlantic telex call.

In replying to the queries In para3 5 and 6, could you also please let ma know when you would be ready to undertake some test calls from subscriber to subscriber (which would, we suggest, be on a free basis) to establish whether the 5 minute target oould be consistently achieved.. Subae;_u©_it 'exercise' calls by the subscribers to satisfy themselves chat the facility could still be used in times of real need, would be on the basis of paid telex calls. I would barao3tgrateful If < a could now settle this quickly as the Foreign Office are getting inpatient with us. Yours sincerely, (G.H.
