3. OPERATION
OVERVIEW
This section discusses the normal operations of the Model 30 Worldpatch. It is
divided up based on the types of operations performed. The operation of the
interconnect will depend on whether the SelCall or Mobile-to-Mobile calling are
enabled or disabled.
BASIC CALL TYPES
Phone-to-Mobile Calls
When the telephone line rings, the Model 30 will wait the number of
programmed RINGS TO ANSWER before reacting to the call. This allows for a
parallel phone to be manually answered before the Model 30 attempts to process
the call. What happens next depends on whether or not the SelCall feature is in
use.
If SelCall is disabled, the Model 30 will begin ringing out on the radio channel.
The Model 30 may be configured to ring either once and wait up to 1 minute for
an answer, or ring each time the phone rings for up to 1 minute. If a mobile has
not answered within this time, the call is terminated. Once a mobile answers, the
Model 30 will take the phone off hook and allow the call to progress. If the line
rings for 10 rings past the number of programmed RINGS TO ANSWER, the
phone will be answered and the user may enter the program access code to
remotely program the Model 30.
With paging enabled, incoming phone calls are answered after the appropriate
number of rings. Once answered, the caller will hear two beeps as a prompt to
enter the radio’s capcode. The page is then transmitted followed by ringing until
the mobile answers or the call times out at 1 minute.
When the Worldpatch is programmed for Direct-to-Air operation, the caller will
be placed directly onto the radio channel after the page is transmitted. Enabling
the Direct-to-Air security password, requires the caller enter a password before
being prompted to enter the called radio’s capcode.
Both DTMF and Two-Tone paging formats may be enabled in the Model 30.
This requires an added digit at the beginning of the capcode to specify the type of
page desired. A “1” tells the system that a DTMF page is to be placed and a “2”
specifies a two-tone page. For instance, if a DTMF paged radio had a capcode of
“456”, the caller would enter: “1456” when both paging formats were available.
Likewise, a two-tone capcode of “85” would be entered as: “285” in a dual
format Model 30 Selcall Worldpatch.
