Range: 30 to 330 (%).
Default: country specific.
# Min Inter-Digit Time – The minimum time between two
consecutive pulses to be considered as separating between
two digits when using pulse dialing.
Range: 200 to 1000 milliseconds using steps of 10 ms.
Default: country specific
! Line Parameters –The Line Parameters define the telephone line
DC characterisitcs and also the AC impedance. These parameters
are correlated because of their influence on power consumption and
power dissipation.
The Line Resistance parameter affects the limits and range for other
parameters to be programmed. The limits are adapted automatically
in the Monitor Interface.
The Monitor interface also includes a wizard, to guide the user in
programming these parameters in the best order. The wizard
displays the status of all parameters programmed up to a specific
moment.
The Line Parameters are applicable only to SUs with Voice HW
Revision D.
" Max Line Resistance - the maximum resistance of the
telephone line.
The available options are 100 Ohm and 540 Ohm.
Line resistance of 100 Ohm means: ~350m on 26 gauge AWG
(0.404mm), ~550m on 24 gauge AWG (0.511mm), ~850m on 22
gauge AWG (0.643mm) ;
Line resistance of 540 Ohm means : ~1800m on 26 gauge AWG
(0.404mm), ~2970m on 24 gauge AWG (0.511mm), ~ 4590m on
22 gauge AWG (0.643mm).
Default: country specific.
" Max Line Current - the maximum current in the telephone
line.
The available options are 20, 23, 26, 29, 32, 35 and 38 mA.
Default: country specific
" Min Off Hook Detection Current - The minimum current for
decision on an off-hook condition.
Range: [1…19] x 1.27 mA. (1 is for 1.27 mA, 2 is for 2 x 1.27 =
2.54 mA and so on).
The Minimum Off-Hook Detection Current must be lower than
the Maximum Line Current and higher than the Maximum
On-Hook Detection Current.
Default: country specific.
" Max On Hook Detection Current - The maximum current for
decision on an on-hook condition.
Range: [1…15] x 1.27 mA. (1 is for 1.27 mA, 2 is for 2 x 1.27 =
2.54 mA and so on).
The Maximum On-Hook Detection Current must be lower than
