In response to the following:
>From: levitt@zorro9.fidonet.org (Ken Levitt)
>Subject: RS-232 Standards for phone wire
>I would interested in any proposed standards for passing RS-232 over 6
>wire phone connectors. If you or anyone else have this information,
>would you please post it or send it directly to me.
The following are standards that I developed for Encore Computer Corp.
(F.K.A. Gould Inc., Computer Systems Div.). I hope this diagrams are
useful to those on net.

Connection Instructions
The attached diagrams should assist in the installation of
terminals to computer ports via the "ENCORE Universal Wiring
Plan".
Materials Necessary:
3 pr. 24 AWG Telephone wire
DB-25 Rs-232 Connectors
6 wire modular telephone line cords, 7 ft, 14 ft, or
25 ft. (One end will be cut off. See diagram for
end to save. Each end is different.)
Punch Tool
Refer to the "Universal Wiring Plan New Installation" Sheet.
Your building has been wired to this specification. Most
outlets where a telephone is present, also has the
capability of supporting an asynchronous terminal. It is
necessary to make cables which connect the terminals to the
telephone jacks, and cables from the Data Backboard to the
Computer Ports.
In cases where there is more than one Computer Room, it may
be necessary to cross connect in the Telco-Room from the
Data Backboard to the appropriate Computer Tie Cable. Cross
Connect all six wires from the data backboard run (cable run
from the Terminal location) to the next available wires (pin
positions) on the Computer Tie Cable Type 66M Block. The
same 'pin positions' in the computer room will be used to
connect the Computer Port Cable.
Refer to the attached sheets for Cable Specifications.
