2. Introduction
2.1 Overview
The Standard Patch Panel supports data transmission speeds of up to 2 Mbps. The system is transparent to all
protocols. Depending on the system configuration, the interfaces supported can include RS-232/V.24 (DB25)
or V.35 (DB25 or M/34). The two types of modules that can be installed with the Patch Panel are test modules
and patch modules.

A Standard Patch Panel chassis can house one test module. Each test module includes circuit activity LEDs and
associated test points, a front-panel monitor patch cavity, a connection to a rear chassis monitor port (DB25)
for optional external test equipment, and a lamp test button.

A Standard Patch Panel chassis can house up to 16 patch modules. Each patch module includes circuit activity
LEDs, a front-panel monitor patch cavity, a front-panel DCE patch cavity, a front panel DTE patch cavity, and a
connection to a set of rear chassis DCE/DTE ports (DB25 or M/34).

The Standard Access Module is used mainly for connecting a tester that doesn’t have patch capability. It allows
the patch in the front to go directly to the DB connectors on the back of the chassis.
2.2 Parts Description
