Section 700 - Operation Chapter 3. System Features
576-13-700 DBS 576 (USA), Revised 6/11/98 33
assignments in the DID Table, names or trunk numbers are displayed. (Names can be up to 10 digits
long.)
DID Ringing can be very useful by sending calls directly to a specific extension, hunt group, etc.
based upon the number dialed. Since a relatively small number of trunks handle the DID calls, this
can be more cost efficient than DIL trunks or attendant group answering and transfer. (DID may send
a call to a group using the Virtual Extension feature.) DID Busy/Delayed Ringing is also available
with DID Ringing. (See “DID Day/Night Busy/Delayed Ringing” on page 61.)
For more information on DID CO Trunk Interface, see “CO Trunk Interface - DID” on page 34.

Considerations
• Caller ID takes priority over the DID name assignment.
• Only one of the two DID tables may have name assignments.
Direct In Line Ringing
DIL Ringing allows calls on a specific CO line to be directed to ring a specific extension, System
Speed Dial (SSD) number (for redirecting calls out), and hunting group.
This can be very useful when a trunk is dedicated to a specific person or purpose. However, this can
be a more expensive use of the line since it has a more limited use.

Direct Inward System Access Ringing
DISA Ringing (which is related to the DISA feature) allows a CO trunk specified as a DISA CO trunk
to ring and give off-site users dial-in access to the System. Once the DISA trunk is accessed, the user
receives dial tone and may dial an extension.
For more information on DISA, see “Direct Inward System Access” on page 40.
