Configuring the Dial Plan for the 4ESS Protocol (T1) 75
Configuring the Dial Plan for North American Long Distance
In the NBX system dial plan, if you are using the 4ESS protocol and you
want to make long-distance calls, you must remove from the dial string
any digits that are dialed by users to access the long-distance service. For
example, if users normally dial 9 and then 1 to obtain a long-distance dial
tone, and then dial a 10-digit number, the dial plan must remove the 9
and the 1 and present only the 10-digit number to the long-distance
carrier. Otherwise, the 4ESS protocol rejects the call.
Example: If you use route 1 in the dial plan for Long Distance, and users
must dial 91 to make a long-distance call, the dial plan entries shown in
Figure 20
remove the first two digits (91) and submit the remaining 10
digits to the long-distance carrier.

Configuring the Dial Plan for International Long Distance
In the NBX system dial plan, if you are using the 4ESS protocol and you
want to make international long-distance calls, you must remove from
the dial string the digits 9011 that are dialed by users to access the
international long-distance service. For example, if the user dials the
string 9-011-44-1234-567890, the dial plan must remove the 9011
before passing the dialed digits to the long-distance carrier or the 4ESS
protocol rejects the call. See Figure 21
.
