Line Programming
Conditioning a line port as PRI B Channel.
When you plan for a line to provide ISDN–PRI service, you must program it to be a PRI B Channel line. The
system automatically defaults to this programming setting for any lines that you assign to a T1/PRI board. With
the line conditioned to be a PRI B Channel line, you must set the DID/DNIS parameters for the line.
Making The DID/DNIS Programming Choices
The common carrier supplies DNIS information as DTMF digits. When the DNIS feature is combined with the
Automatic Number identification (ANI) feature, the common carrier delimits the ANI information from the DNIS
routing information with the asterisk (
✳
) tone so that the system can process each portion properly.
The system uses information that you program in the DID/DNIS translation table to route the call to the proper
intercom number. The system also sends the called number information to the SMDR/SMDA line report and
makes the information available to devices that are connected to the Open Architecture Interface (OAI).
As a single service, if the call routes to an LCD speakerphone, the speakerphone’s display shows the name that
you programmed in the DID/DNIS translation table. If you have programmed no name there, the display shows
the DNIS/DID block name that you assigned to the DID/DNIS block. If you have programmed no name there, the
display shows the processed DNIS digits. (As a DNIS/ANI combined service, the display shows the processed
ANI digits.)
DID/DNIS Block Name—Choose a 7-character name to associate with each DID/DNIS block. End the
DID/DNIS block name with a space if you desire a blank space between the name and the CO digits when
they show on an LCD speakerphone’s display. Also, the number of CO digits that will show in the
display is dependent on the length of the DID/DNIS block name.

End the DID/DNIS block name with a space if you desire a blank space between the name and the CO
digits when they show on an LCD speakerphone’s display. Also, the number of CO digits that will show in
the display is dependent on the length of the DID/DNIS block name.
Expected CO Digits—Type quantity (0–7) of digits and press ENTER.
Obtain a block of numbers for use from the CO. The system supports a maximum of 400 numbers (for
example, 555–1000 through 555–1399). You can have a maximum of four DID blocks with each DID
block using its own name, signalling 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.
You will derive maximum user convenience if you choose the CO block to match the intercom numbers
that you have assigned to the 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, which
covers 1000 through 1399. If the CO block was 555–1100 through 555–1192, the string quantity would
be two, which covers 00 through 480.
ANI Delivery—Press SPACE bar for Yes or No and press ENTER.
Enable or disable the system to process ANI information that is delivered by the long distance common
carrier as a T1 feature on dial 800 and dial 900 lines.
Information Digits—This option does not apply to T1/PRI. Be sure it remains disabled.
