RJ11 mounts
The RJ11 came in flush mount (also referred to as a wall jack) with the profile of an electrical plug plate, and
in surface mount (also called base board jacks).
The flush mount was installed in a wall box, “caddy fastener”, or a “mud” ring.
Normally these jacks were installed at the level of the electrical plugs, with the top of the plate about 35 cm
(or 14 inches) from the floor.
These jacks also came in “duplex” versions (2 RJ11 jacks) used for xDSL.
Leviton jacks
Leviton jacks are one of the termination types currently used. The jacks are inserts that “clip” into the
faceplates shown here. They are considered flush mounted since they mount to an 1104 box installed in the
wall during the construction of the building. They can also be surface mounted, using the same inserts as
flush mounts.

Wiring standards
For residential data purposes, the standard is T568A. The cat 5 color code and plug pin configuration for this
standard are shown below.
You can also see the color code for older wire. In both cases the dial tone goes to the back pair of connectors.
