8.4. IDirect In ward Dialing Line Examples
Example 1:Jenny’s Bakery has the following CO numbering blocks:
555-3600 to 555-3619,
555-4520 to 555-4539,
555-1200 to 555-1399.It will receive the 36nn and 45nn calls through CO lines l-5 and the lnnn calls through CO lines 6-8. The system
requires two DID blocks for use: block one for CO lines l-5, and block two for CO lines 6-8. The numbers in
DID block one have two unique digits and the numbers in DID block two have three unique digits. Assume that
DID...

8.4.2DID Options
DID/DNIS Block NameDescription:
Choose a T-character name to associate with each DID/DNIS block.Programming:
Refer to Section 8.43.DID Control 
SignallingDescription:
Decide upon which address supervision signalling protocol that you will use. This decision will
depend upon the type of supervision that is compatible with the CO requirements.
Immediate Start: Use this protocol for rotary (pulse dial) lines. With this protocol, the CO will
not expect address supervision signalling and may...

Expected CO DigitsDescription:Obtain a block of numbers for use from the CO.The DXP Plus 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...

8.4.4DID/DNIS Translation Tables
Description:When you initialize a translation table, you must first enter the string of CO digits that you
obtain from the telephone company. Then you must enter the intercom number that you want to
match with the first CO digit sequence in the string. With this, the system automatically
matches the remainder of the CO digit string to consecutive intercom numbers beginning with
the one that you entered. You can edit the translation table by selecting the item number for...

8.5Ground Start Line Support
Description:The multipurpose line board provides system interface for loop start lines, ground start lines,
and E and M tie lines. These are typically the three different line types that the central office
(CO) makes available for connection to the public switched network. With the ground start line
type, the DXP Plus momentarily grounds the ring lead to signal the CO to establish acommunications link for an outgoing call. When the CO detects this, it acknowledges by...

and E and M tie lines. These are typically the three different line types that the central office
(CO) makes available for connection to the public switched network. With the loop start line
type, the DXP Plus bridges a resistance across the tip and ring leads to signal the CO to
establish a communications link for an outgoing call. The CO detects the resulting current flow...

8.7Pie Line Support
The multipurpose line board provides system interface for loop start lines, ground start lines, and E and M tie
lines. These are typically the three different line types that the central office (CO) makes available for connection
to the public switched network. The tie line connections (also known as tie trunk access) are special circuits that
allow, on either a dial-up or a continuous connection (hot line) basis, the DXP 
Plus to communicate...
