Pickup Dialling; Polarity Reverse Detection; Power Failure Transfer; Preferred Line Assignment - Incoming - Panasonic KX-TA624 Product Description

KX-TA Advanced Hybrid System

Pickup Dialling

Allows a single line telephone user to make an outgoing call by going off-hook, if the user has
stored the telephone number (up to 32 digits) beforehand. This feature is also known as "Pick
Up Dial" or "Hot Line".

Polarity Reverse Detection

The circuit in the system can detect the reversal of exchange line polarity from the Local
Exchange when making an outside call. This detects answer (the called party goes off-hook)
and end (the called party goes on-hook) of an outgoing outside call. The conversation time
can be verified on the SMDR printout using this feature. When an outside call is received, the
circuit can also detect the polarity reverse signal before ringing helping to prevent call
collision.

Power Failure Transfer

During power failure, specific extension telephones are automatically connected to specific
exchange lines. This allows limited operation between the following extensions and
exchange lines.
Exchange line 1: extension port 01
Exchange line 4: extension port 09
Preferred Line Assignment — Incoming
A proprietary telephone user can select the method to answer incoming outside calls from the
following 3 line preferences. System Programming and Proprietary Telephone Settings are
required.

No Line Preference (Manual Answer)

When an incoming call is received, the extension user must go off-hook and then press the
flashing line key.

Prime Line Preference

When more than one incoming calls are received at the same time, the user can receive the
call on the preferred exchange line by only going off-hook.

Ringing Line Preference

When an incoming call is received, the user can receive the call ringing at their telephone by
going off-hook.
