Specifications
Expected CO Digits
Obtain a block of numbers for use from the CO. The DXP supports a
maximum of 400 numbers (for example,
5551000
through
555-l 399). You can have a maximum of four DID blocks with each
DID block using its own name, signaling protocol, digit addressing
method and number of digits needed to avoid numbering conflicts. As
a default, the system assigns all DID lines to block one. A DID block
represents a group of lines that the system will use to receive calls for
one or more CO directory number blocks.
NOTE: You will derive maximum user convenience
ifyou
choose
the CO block to match the intercom numbers that you have
assigned to the DXP system. (For example, if your
intercom numbers are 1000
-
1399, they would match the
sample CO block.)
Determine the quantity of unique digits in the string that you expect to
receive from the CO. The number of digits expected should be large
enough to avoid numbering conflicts within a DID block and provide
future growth. In the case of the CO block mentioned above, the
quantity of unique digits is three to cover 1000 through 1399. If
the
CO block was 555-l 100 through 555-l 192, the string quantity would
be two to cover 00 through 192.
Dialing Mode
Based upon the system’s expected incoming call volume and
recommendations and requirements of the CO, determine whether the
CO will send address digits by
DTMF
tones or by loop pulse (rotary)
dialing. (Always choose DTMF tones if possible.)
ANI Delivery
Enable or disable the DXP to process AN1 information that is
delivered by the long distance common carrier as a
Tl
feature on dial
800 and dial 900 lines. Refer to Section 8.7.4 for details about the AN1
feature.
DISA Voice Options
Use the DISA Voice Options 1 through 4 to select digital voice
announce (DVA) message levels. For example, selecting DISA voice
option 2 will cause welcome greeting 2, day main menu 2, night main
menu 2, recall no answer 2, and recall busy 2 prompts to play
whenever a DISA-configured DID line is covered by DVA. Refer to
Section 16 for complete DVA programming details.
