Unit installation

5. Operation
ProHold DRDX is extremely simple to operate. Once the unit has been proper-
ly installed the only action you have to perform is to call your studio and give
them the phone number of the ProHold DRDX unit.
Your studio will help you customize your production and preferences. As soon
as you give your final approval, your Message is ON LINE working for your
business. No waiting for the snail-mail express!
6. Typical
Configurations
ProHold DRDX is extremely flexible and can be configured many different
ways. Here are three typical configurations.
6.1 Direct Connect
Direct Connect is the simplest ProHold DRDX configuration. The unit PSTN
interface is connected to a direct dedicated outside line. This line is only used
for ProHold DRDX access.
6.2 Time Share
Time Share allows the ProHold DRDX to share its access line with some other
user application or equipment. There are two different flavors of this type of
connection:
6.2.1 External Share Device
In this configuration the incoming phone line is split via an external device
(Line Switch) into separate USER and ProHold lines. These lines share the
same physical number and it its the responsibility of the Line Switch to differ-
entiate between incoming USER calls and ProHold calls. This method is highly
reliable, inexpensive and maximizes the users resource usage.
