A handset connected at Z2 should have the following
connections:
remark: observe polarity of the electret microphone
7.3 Setting dialing mode
By J2, a selection of 3 different dialing modes can be
made, 2 pulse (=LD) dialing modes and a DTMF
dialing mode.
If LD Mode is selected then it is possible to switch
into MF mode by pressing the
!
key but the mode
will return to LD after a hookswitch operation or after
a Recall (flash). In LD mode pulsing is at 10 pulses
per second.
7.4 Setting line loss compensation (AGC)
Line loss compensation = line current dependent
gain setting of Tx and Rx amplifiers can be set by
jumper setting to 3 different modes : high, low and
no LLC (=default).
7.5 AC impedance
The Characteristic or output impedance of the SA2532K is set internally to 600
. No further components are
required. For a complex impedance refer to pt 11.
