Connection for the handset, an answering machine, or a telephone
Connecting the handset or a telephone to the LASER CLASS 2060P allows
you to use it to make and receive normal telephone calls. In addition,
connecting an answering machine allows you to receive faxes and phone
messages while you are away from your desk.
Distinctive Ring Pattern Detection capability (DRPD)
The DRPD feature of your LASER CLASS 2060P allows you to have two
or more telephone/fax numbers assigned to your LASER CLASS 2060P
using only one telephone line. You can use this feature when you
subscribe to a DRP service offered by some telephone companies.
