Griffith of COTC rolatlvo to the establishment of telex facilitloo between London Traffic Contro and Ottawa Traffic Contro (Leitria)to supplement the existing leased oable olrouit which was set up for Alerts uoo. Wo hare at tho moEcnt onolcaocd dir lax channel in the cable between COTC Montreal and .'.-0 London with two duplex circuits (tie-lino) between Loitrim and COTC Montreal whioh work in parallel to proolude the breakdown of facilities should eithor crl of the olroult8 fail. Tho cooond duplo : circuit between Leitrim and COTC Montreal was _uf .od in 1959 at the suggestion of Sir Patrick Dean to provide "Insurance" for that part of the circuit bo'ut/oc_i Loltrln and Montreal whioh was oonaidorod sono1-1TO. Tho ceoond duplex olrouit docs not, howevor, eiaabl^ Leitrim to use one of tho Telex ohannels In the sable between Montreal and Lor.don should it be neccs-jary to preempt this facility. Tho suggestion that we provide a Telex machine at Leitrim with a private simplex olrouit to COTC Telex Montreal is a good one sir.ee qui to apart from being then able to pre-empt a Telex Circuit in the cable between Montreal and Londc.i when i.n o _ rgency arises it would also maiio it posjlblo for COTC to re-route the transatlantic circuit should the cable fall for one reason or another. This waa In foot done when the cable was cut some time ago and our Tolex calls were routed . . London through Melbourne, Australia and Singapore. We have obtained fro.; the CNT/CPT an estimate of oost for the private telex olrouit froa Leitria to Montreal as follows: CIRCULATION Telex unit rented (includes transmitter and reperforator) Line rental Non-recurring installation charge ' 77.00 ( p or ..ontb; 132.20 (per kaonth! 40.00 The annual cost of such a facility would therefore be $2,510.40 with an initial oharge of $40.00 for Installation.

Wo have not dlsouoocd with D/Slgo Aray the installation of this additional machine at Leitria but would antiolpato no difficulty once the decision to proceed with obtain!ng this "insurance" is made. In previous negotiations regarding modifications to Alerts facilities the initiative for change has come from tho Foreign Offioe to you. This correspondence between Mr. Coatos and Mr. Griffith appears to stem from tho original installation of the second duplex channol between Leitrim and Montreal and Is, I am sure, the expression of a genuine request froa Foreign Off loo. It would, however, I thinlc, be somewhat inooncjruc"-tG for ua to proceed without a request from the Foreign Offioe for thl« additional service and I should be grateful if you would approach the Foreign Office in this regard.
