The trunk group number will define the DDI table area for each night mode (Program
22-13-01).
The DDI table area is defined by Program 22-10-01. You now have the DDI conversion
table to be used as the convert table.
The quantity of digits that the DISA caller must dial is define by Program 22-09-01
(default is 4 digits).
The digits received are then compared to the receive dial entries of the DDI table
(Program 22-11-01), if an exact match is found the call will be routed to the DDI target
number (Program 22-11-02). If a match is not found the DISA call will be disconnected.
If the DDI target number is invalid the call will not use the DISA option for Wrong Dial
(Program 25-03-01). If the DDI target is invalid the options for the DDI will be used
(Program 22-11-06 & 06).
If the DDI target number is busy/no answer the call will not use the DISA option for
Busy/RNA (Program 25-04-01). If the DDI target is busy/RNA the options for the DDI
will be used (Program 22-11-04).
DISA Password/User ID
You can enable/disable the DISA password per trunk port by Program 25-01-02. When
enabled all DISA callers must enter a valid 6-digit password before the call can
proceed; the password s are defined in Program 25-08-01. The DISA password is used
to assign a DISA Class of Service.
If the DISA password is disabled the incoming caller does not need to enter any
password to access all of the DISA options.
Care should be taken when the password is disabled as any DISA caller can access
outgoing trunks and paging zones etc.
Warning Tone for Long DISA Calls
You can set up the system to provide a warning tone to DISA callers that have been on
a call too long. The warning tone can be just a reminder (which the caller can ignore) or
can be followed by a forced disconnect of the call. When the DISA caller hears the
warning tone, they have the option of Dialling a code to continue the conversation or
disconnect.
Conditions
A. The DISA caller must use a DTMF dial telephone. DISA is compatible with calling
devices that meet the DTMF signalling requirements of EIA Specification RS-464.
DISA trunks must be supervised loop start.
B. When accessing Topaz from a remote location via a DISA trunk, a specific DISA
tone will first be heard when the system answers (a fast alternating tone). After
the correct password is entered to allow system access, the tone changes to a
mono tone. It is at this time that allowable system features can be accessed, e.g.,
access code for internal paging. If the caller enters the wrong password (a warn-
ing tone will be heard), they can repeat the password entry up to 3 times before
being disconnected.
Default Setting
Disabled.
