Analog (Single-Line) Telephones
Single-line telephones are an economical choice for users who do not handle many calls and do not use
modems and fax machines extensively.
All signals between analog telephones and the DEFINITY system are analog over a pair of wires. Only one
incoming call can ring at a time, but the telephone can actually handle two calls — one active and one on
hold. Depending on the particular telephone, you can alternate between two calls or set up a three-way
conference using the switchhook or flash button. You can access DEFINITY voice features by either
entering access codes from your touch-tone keypad or pressing feature buttons.
