The telecom line is used to call the above remotely
installed equipment which will manually
|
|
or automatically connect hold coil to the line, causing
ringing to cease and circuit to be established.
|
| |
|
The D.T.M.F. signal can now be fed down the line. These
are received and decoded by the remote
|
|
equipment which causes appropriate logic circuit to
go high or relay to latch in held (energised) condition
|
|
.
|
|
Any established mode can be released normally by use
of HASH symbol on key pad.
|
|
Where unit incorporating auto line claim and release
is used board will respond after three rings
|
|
establishing a D.C. path across the line thus causing
ringing signal to cease.
|
| |
|
Unit will automatically disconnect from line three seconds
after it is released at the local end.
