Pulling out cables
Continuing with removing the old obsolete cat-3 25-pair voice cables at the Hawthorne C.O.. The terminal room has backboards on the west and north walls. The north wall was(is) the KTS and 25-pair floor cables. The KTS cables have been removed; I'm removing the floor cables 'cause they are blocking the running of new Cat-5 cables. Still have six dial tone lines on those cables that need to be moved to the four-pair cables, either cat-5 or cat-3.
Out on the floor I'm mining out the old cables -- the aforementioned 25-pair cat-3 cables. AND.....
!!! 3-pair cables that were used for Netway -- That was a six wire serial system that connected data terminals and printers to a main frame computer. It was replaced in the 1980's.
!!! SSI cables -- were used with AT&T 4500 series devices, terminals, printers, and controllers.
!!! Cables with db-25 RS-232 connectors on them
!!! Coax cables with 1/8" phone plugs on them -- were used by the data test center that closed in the early 1990's.
Mixed with these are 4-pair plenum rated cat-3 cables that terminate on the west wall of the terminal room, which wall also has the house cable. These cables to remain available for straight dial tone or other applications that come up on the house cable.
