Introduction
The Model 48 Telco Switcher is designed
to allow fast and efficient routing of tele-
phone-line signals to multiple destinations.
Using passive switching circuitry each of
the six sources (inputs) can be selected
for use by the five destinations (outputs).
The unit is specifically designed for mobile
broadcast news-gathering applications,
but is applicable for a wide range of
mobile and fixed applications.
Broadcast operations have experienced
a proliferation of wired and wireless tele-
phone signals. These signals are often
utilized by multiple devices, such as IFB,
intercom, modem, and fax equipment.
Routing these signals to their required
destinations can be inefficient, confusing,
and sometimes unreliable. The Model 48
addresses this need, allowing the rapid
connection of multiple sources to multiple
destinations. In addition to the operational
features, the Model 48 uses standard
telephone-type connectors, allowing a
clean installation and easy long-term
system maintenance.
The Model 48 installs in one space of
a standard 19-inch rack. Seventeen
6-position modular jacks are used for
source (input) and destination (output)
connections. The Model 48s jacks and
switches are compatible with wet (DC-
biased) or dry signals. The unit is com-
pletely passive; no external power source
is required.
