Function Description 4.1
56
Traditional Button Telephone
Any number can be “dialled” in this mode. To dial, press , and to hang up use .
These keys are typically provided with pictograms and . PSTN calls can be
barred for a line in the PBX. The dialling type (tone, pulse) is selected in the
programming mode. With pulse dialling, the
character initiates (upon off-hook)
transition to tone dialling – like on any other telephone.
Note
 If this function is enabled, you can press to hang up an outgoing call
initiated by pressing a separate button.
DTMF Transmission during Outgoing Call
This function enables the unit to transmit DTMF tones when the connection with one of
the pre-programmed numbers has been established. It is used in combination with
automatic information systems, voice mailboxes, etc., which ask the calling party to
select a service using tone dialling. This function, however, does not allow you to call
destinations other than the pre-programmed ones.
Buttons Substitution
This function is an analogy to memories in comfortable telephone sets. After two digits
ranging between 01 and 54 (0 may not be omitted) are pressed, the call to the pre-
programmed number is made. You can use 2N® Helios as if it had up to 54 separate
buttons, which saves buying the extender units and space on the installations wall.
The ideal solution is to use a few standard buttons for the most important speed
dialling options e.g. Warden, Reception and then provide a list of pre-programmed
options via the optional info panel that can be purchased.
Admissible Keypad Function Combinations
All of the above mentioned 4 functions can be combined freely – each of them can be
enabled or disabled separately as desired.
