SV9100 General Description Manual 2-25
To use DISA, the employee:

Dials the telephone number that rings the DISA trunk.

Waits for the DISA trunk to automatically answer with a unique dial tone.

Dials the 6-digit DISA password (access code).

Waits for a second unique dial tone.

Accesses a system trunk, uses a selected feature or dials a system extension.
DISA calls ring system extensions like other outside calls. If an extension has a line
key for the DISA trunk, the call rings that key. If the extension does not have a line
key, the extension must have a Call Appearance (CAP) key to answer the call.
You can set DISA operation differently for each Night Service mode. For example, a
trunk can be a normal trunk during the day and a DISA trunk at night. You can also
set the routing for DISA trunks when the caller dials a busy or unanswered extension,
dials incorrectly, or forgets to dial.
DISA allows 15 users, 15 DISA Classes of Service and 400 trunks.
Direct Station Selection (DSS) Console
The DSS Console gives a multiline terminal user a Busy Lamp Field (BLF) and
one-button access to extensions, trunks and system features. This saves time for
users that do a lot of call processing (e.g., attendants, operators or dispatchers). The
DSS Console simplifies:

Calling extensions and door boxes

Placing, answering and transferring outside calls

Making an External or Internal Page

Switching the Night Service mode

Activating DSS Console Alternate Answer
The DSS Console also provides DSS Console Alternate Answer. This lets a multiline
terminal user with a DSS Console quickly reroute their calls to a co-worker.
Transferred and dial 0 calls ring both DSS Consoles and, if the VRS is installed, the
main operator hears the message, “Your calls have been forwarded”. Central office
calls ring both consoles and no message is heard by the operator.
