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.
