Direct Inward System Access (DISA)
Outside callers with touch tone telephones can call in to lines programmed for Direct
Inward System Access (DISA) and dial an extension or outgoing line without going
through an attendant or operator. See your CTX System Administrator for details.
1. From outside the system, dial the public telephone number assigned to DISA. The
call will be answered and you will hear CTX dial tone.
If you do not dial within 10 seconds, the line disconnects.
2. When you hear dial tone, dial an extension or an outside line.
3. If you dial an outside destination, you may need to enter a security code provided
to you by the CTX System Administrator. When you hear the tone, enter the
security code. If accepted, the call will proceed.
4. If you receive busy tone and you want to dial another number while the station is
still ringing, press
and repeat Step 2.
Direct Station Selection Buttons (Hotline)
This optional feature enables you to use a '66 button to connect directly to another
station’s line extension. The DSS LED shows the status (idle/busy) of the station and/
or the station’s primary extension. For example, a station’s DSS button LED shows
busy (light steady red) when the station is:
• busy on a call on any button
• idle but all appearances of the station’s extension are in use by other stations.
When the station is in DND, the LED flashes red.
➤ To connect directly to another station’s extension
1. When connected to a line or another station, press
'66.
The original party is put on-hold. You can call a station even if the DSS LED
shows busy (steady red).
2. Announce the call...or transfer the call by hanging up or pressing
5HOHDVH.
Note You can transfer the call to an idle or busy station.
