The company Telefonos de Mexico, S.A.;5 ‘has sub-gentrected this work of cleaning up and reorganizing the phone : \gystem: to the independent firm, Intel. They are cleaning up unused and .old-lines, putting in new and spare lines, redefining axchangs areas, laying. underground cables, etc. Eventually we should be better off be~ _gause: there should be more surplus lines. The renovation work has hampared much of the LIFEAT work, principally because many of the Lines ‘now ate underground and we carmot get access. to them before they enter _ ,the-central.. This is particularly true with respect to the Czech Em= ' bassy, to whose telephone lines we cannot obtain access from the vantage jPoant | wa now occupy. “> "3, WILSTRD said that we try to keep track of the activities of i "Intel" but since they seem to attack "Colonias" at random, we have no Prior warning of their presence in a certain area. he In the recent past, ‘exico has been using houses for listing posts for security reasons. ‘e have more control over the access of phone company inspectors or repairman to houses. Jlowever, under new regulations, all. new apartment buildings must havo telephone lines ine atalled in the building by the phone company during the construction phase. This means that the lines and their destination are concealed, WILSTED preposed that this will mean we can again use apartments since we can siphon off a line destined for use by another tenant in such a : way that the phone company cannot trace ite destination without tearing Be the building apart and we can then instell a separate line to the build- a ing and hook. up. the subscriber to this line which, if checked, will belong to a legitimate subscribor. Se One system which has been used effectively is to take one-half of two separate pairs which have one faulty line each. These two half paisa then form one good pair which we can use. 6. WIISTED explained that it cost about 3000 pesos to get a ; reguler telephone. This entails the purchase of a telephone company bond, which later can be sold. SECRET
