Modular Connections

- Full Modular desk and wall phones
allow the handset cord to be unplugged from the phone body and from the
handset. On full modular desk phones, the line cord can be unplugged from the
phone body.
- Half Modular is a
description that applies to desk phones only, and is a relatively uncommon
configuration. The line cord can be unplugged from the phone body, but the
handset cord is permanently attached ("hard wired").
- Quarter Modular is
a description that can apply to desk or wall phones. The phone is designed to
connect to a modular jack, but the handset cord is permanently attached ("hard
wired").
- Non-Modular phones have not been made since about 1980. Both handset and line connections are hard-wired.
