Notes:
The Digit String Length defined in this address determines the length of the DID/DNIS numbers entered
in the DID/DNIS Dial Table ("A" Side) (see next address). It must match what is supplied by the local
FF4
CO. If the number received by the system does not match an entry in the table, or if the actual Digit
FF-/Soft Keys
String Length is not the same as specified above, the system will treat the call as a misdialed call (see
DISA Invalid Number on pg. 1-30).
DID (Direct Inward Dial): An outside caller can reach an internal extension directly by dialing a 7-
FF5
digit CO phone number. The DID trunk passes the last 2 to 4 digits of the phone number to the PBX,
Groups
and the digits become (or are modified to become) the equivalent of an extension number. DID trunks
can't be used for outgoing calls (no dialtone offered).
DNIS (Dialed Number Identification Service): Similar to DID, but normally used on digital (T1 or
FF6
ISDN) lines. The DNIS number (the phone number dialed by the caller) is passed to the PBX, and
routed to different extensions based on the DNIS number dialed.
TRS/ARS
To set up DID and/or DNIS Numbers: Set Analog-CO, ISDN, or T1-CO trunks for DID/DNIS in the
Ring Type addresses (FF2). Enter the DID/DNIS numbers, and assign their ring and delayed-ring
FF7
destinations, in the DID/DNIS Dial Table (see next page).
Applications
Two separate DID/DNIS Dial Tables are provided: "A" side and "B" side. One can be used for DID
(analog) numbers, and the other for DNIS (digital) numbers. Another advantage of having two separate
tables: it wouldn't be a problem to receive the same block of 4-digit numbers from the CO, such as 277-
FF8
[2020 thru 2099] and 366-[2020 thru 2099]. The DBS 576 could take care of routing the same 4-digit
number to different extensions, based on which side ("A" or "B") the trunk belongs to. (Trunks are

assigned to "A" or "B" side via their Trunk COS assignment in FF2; also, see Trunk COS: DID/DNIS
Table on pg. 1-77.)
