Component Objects

The DTMF Decode block provides several control output

nodes: nodes 1~D provide indication of corresponding DTMF

tones; Any provides indication of any tones.

Double-clicking the DTMF Decode block produces a control

dialog box. Device IO indicates which hardware connection

is associated with that software block. DTMF Decode

enables decoding. Decoded Data displays the characters

associated with the tones.

The Control/Status block provides several control output

nodes: HS indicates hook switch OFF condition; DTD

indicates dial tone detected; BTD indicates busy tone

detected; RTD indicates ring tone detected; LR indicates

line ready (connected); LIU indicates line in use (by other

extension); LI indicates line intrusion (by other

extension); LF indicates line fault condition (may require

service).

Double-clicking the Control/Status block produces a

control dialog box. Device IO indicates which

hardware connection is associated with that

software block. Auto Disconnect provides three

methods of call termination (the method used

depends on the far-end equipment). Loop Drop

detects interruptions in the current of the telephone

circuit, Call Progress detects a special tone

indicating call termination, and some far-end

equipment may use a combination of Loop Drop +

Call Progress. NOTE: Auto Disconnect reliability

may be affected by intermittent line interruptions or

cellular calls. Line displays voltage, current, and

fault conditions on the line.

NOTES: Before compiling, a Country must be designated in the Receive block Property Sheet.

For protection of privacy, the Last Number Dialed and Caller ID displays (on the Dialer control

dialog box) can be disabled via the Control/Status

block Property Sheet. Sidetone Level can be

set via the Dialer

block Property Sheet.
