After detecting the Ring signal from circuit, Base Unit sends a ring signal DATA (Ring), then the Handset starts ringing.

 Handset :

transmitting ... 28 Pin

receiving ... 16 Pin

 (IC901)
Base Unit :

transmitting ... 97 Pin

receiving ... 59 Pin

     (IC701)

The DATA which is transmitted from the Handset to the Base Unit is combination of DATA 0, DATA 1, DATA Delimit, Pre data

and End data.

The DATA which is transmitted from the Base Unit to the Handset is combination of DATA 0, DATA 1, DATA Delimit, Pre data

and End data.

When Linking from the Handset (when becoming STBY to TALK), DATA is transmitted in above format. The combined
portion of DATA 0 and DATA 1 is transmitted in LINK requesting DATA (40bit) format first. Then, when LINK OK (ACK-OK)
DATA
(46bit) is returned from the Base Unit, it is sent as LINK from DATA after changing the combination of DATA 0 and DATA 1. And
the DATA Delimit is between each Frame as a stop.
The contents of LINK requesting DATA and LINK form DATA are different depending on each operation.

When executing Pulse Dial, the Pulse Dial DATA is transmitted from the Handset to the Base Unit in above format.
The combination of DATA 0 and DATA 1 are changed by each Dial No. And the DATA Delimit is between each Frame as a stop.
The number of Frame is 2.

  Tone DATA

13 bit

DATA Delimit

When executing Tone Dial, Tone Dial DATA is transmitted from the Handset to the Base Unit in above format.
The DATA is changed by Dial No. as same as Pulse Dial. When Tone Dialing, DATA (Continue DATA) that the key is pressed
continuously is sent to the Base Unit during the key is pressed.

     

1,000,000 kinds of the security code are available for the model

KX-TG2570B/KX-TG2570S. Each time the handset is set on the

cradle of the base unit (for charging), the CPU automatically

change the security code.
