It was agreed that Mr Cook will finalize the proposed circuit arrangements to enable STRAD-to handle the Alerts messages (as discussed in para 8 of the Record of the Third Meeting) for reference in case needed0 This will be circus lated to DCE and HQ CFCS for comment,, 3$ was decided to defer development of this circuitry pending further inform** atlon from the British authorities* Mr Cook EDC FOR ALERT • I I I I M M P — W — » — » I I « I 1 W I * X W W * lUo Lt Col Kelly pointed out t h a t t h e r e i s possibly a considerable load time involved i n acquiring EDC equipment for both ends of the Alert « HYDRA radio c i r c u i t 0 The a n t i c i p a t e d delivery data w i l l be confirmed a t the next meeting hy DCE<> SECRET DCE o » o/jj 000069 �SECRET Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a /'information ACTION t~^_ 15<> Because it is an Important circuit for support of Alcsrt, and because it must be EDC - protected in order to connect to STRAD, it was agreed that 3 EDC units allotted to the Newfoundland REGHQ shall be loaned for this purpose pending receipt of those ordered for HYDRA, This loan is dependent upon the forthcoming discussions with EID on the completion of the four remaining REGHQs; if the EMO schedule calls for early" Installation of REGHQ communicationss this loan will have to be reconsidered,, DCE will arrange the loan under these terms© DCE CIRCUIT SWITCHING 16, Lt Col Hamilton reported on his meeting with CB NRC as called for in para 13 of the Record of the Third Meetings A3 a result of these discussions it is now agreed that, while there remains a need for a HYDRA STRAD supervisors console in the operating area, there is no need for a separate circuit patch position in the operating area0 The patching of circuits (both on^STRAD and off-STRAD] can be programmed with adequate lead time to enable the patching to be effected at the main CARP circuit control position,.
