3. EMULATE PARAMETERS
The
EMULATE
parameters are used to define the values and timing of the events initiated by
the AM8a. These parameters are only used when the Te/Line or Switch is set to
CONFIG
"
MODE emulate
". When set to "
MODE monitor
" they are not used, and also cannot be printed at
a terminal.
3.1 LOOP EMULATE
This menu is used to setup the characteristics of the interface when configured as an analog
LOOP START TRUNK TYPE
.
LOOP : VOLTAGEvdc

20 to 72
LENGTHohm

0 to 2100(300ohm steps)
Alternate:
3.1.1
VOLTAGE:
This is the battery voltage that will be supplied by the AM8a when
configured to emulate an analog switch (refer to 2.1 and 2.2).
3.1.2
LENGTH:
This parameter allows the selection of the loop length to be simulated by the
AM8a.
3.2 TERMINATION EMULATE
This menu controls the termination for the analog signals on the trunk.

Alternate:
3.2.1
2.16uf:
2.16 microfarads is a standard capacitive component of the termination
impedance when set to
IN
.
out:
the capacitance is increased to 24uf so that it has little or no effect on the
termination for audio frequencies from 200Hz to 3400 Hz.
