38 CHAPTER 2: DIAL PLAN
Example: You can assign the company’s Vice President of Finance to a
group that you name the All Privileges Group. You can set the
permissions for that group so that group members have permission to
make LongDistance calls during all system modes.
Internal Dial
Plan Table
The Internal dial plan table (table ID 1) defines how to handle calls placed
from internal devices, such as NBX Business or Basic Telephones, to a
destination. A destination can be another internal device, such as a local
telephone, or an external telephone line (Analog Line Card or Digital Line
Card) that connects the NBX system to other facilities.
The Internal dial plan table consists of a series of commands. For an
example of the command format, see “
Dial Plan Command Format”
earlier in this chapter. Table 6
on page 35 describes each element of the
command. Table 7
describes the predefined routes.
You cannot delete or modify predefined routes, only create new routes.
Each device must have a Normal table. The Least Cost Routing table is
optional. Telephones use the Internal dial plan table (table ID 1) as their
normal outbound table and the Least Cost Routing table (table ID 3) as
their long distance routing table.
Incoming Dial
Plan Table
The Incoming dial plan table (table ID 2) defines how calls arriving from
outside the NBX system are routed to extensions. Incoming calls can
arrive on analog telephone lines or through Digital Line Card ports.
The incoming dial plan table consists of a series of commands. For an
example and basic understanding of the command format, see “
