If the user wished to manually enable the near end speech path (from TP18 to the line), the following
commands would be entered:
>ok
f!<Return>
>05 08<Return>
; sets HI port A bit 3, energising relay 1
>07 08<Return>
; sets HI port C bit 3, enables speech input (TP18)
><Esc>
>ok

Application/Demonstration Commands

cas
Follows the CAS detection part of the CIDCW algorithm detailed in the FX602 data
sheet. Near end speech is input between TP18 and VSS (TP1 or TP2 ). If the detect
output is set for a time longer than T1, the near end speech path (TP18 to the line) is
muted. If the detect output then remains set (making a total detect time longer than T3
but less than 65ms) then, after a quiet period of 50ms, the DTMF digit "D"
acknowledgement tone is transmitted down the line.
Once this sequence has been completed, or aborted for not meeting a timing
requirement, the near end speech path is un-muted and the FX602 returned to tone
alert mode.
On the EV6020 board, the line termination resistor R20 (
≈ 600) should be fitted.
Note that this software does not present an off hook dc load to the line.
casd
Operates as above, but two decimal counters are run. The first counts the number of
times the near end speech is muted and the second counts the number of times the
DTMF acknowledgement is sent. The results are displayed and updated in the form:
M=00000000,A=00000000.>
where M represents mutes of the near end speech path and A represents
acknowledgement tones sent.
On the EV6020 board, the line termination resistor R20 (
≈ 600) should be fitted.
Note that this software does not present an off hook dc load to the line.
cast
This enables the user to adjust the CAS detection algorithm timings T1 and T3. The
user is prompted as follows:
T1=3A98>
Type <Return> for no change, or enter the new setting (in
s) in hex.
e.g.
For T1 = 10ms = 10,000
s = 2710hex, type 2710<Return>
The user is then prompted to alter T3 in the same way. The default settings are T1 =
15ms = 3A98hex and T3 = 25ms = 61A8hex.
