1.6.2.6 Type 2/off-hook demonstration dialog box
Ensure that a valid DTMF digit, for the CIDCW acknowledgement tone, is set from the main panel
before running this demonstration
• The EV6120 is instructed to perform the off-hook / type 2 / CIDCW demonstration. The nature of
the demonstration can be altered by selecting Feature Phone or Adjunct Box and Early or Late
muting on the right hand side of the dialog box.
• If FSK +6dB is checked the gain in the input path formed around AOP1 of the CMX612 is
increased by 6dB for the FSK receive part of type 2 CLI. For the feature phone case this will also
switch the input path from AOP2 to AOP1 of the CMX612 during the FSK receive.
• The valid CAS detects and local Mute counters are provided to assist with talk-off and talk-down
testing, see later sections.
• CLI message data is shown as described for the type 1 dialog box.
