The Incoming Dial Plan table (table ID 2) defines how calls arriving from
outside the NBX 100 are routed to extensions. Incoming calls can arrive
on analog telephone lines or via Digital Line Card ports.
Each table entry contains:
The table number (always 2 for the Incoming Dial Plan Table).
I
The table entry number (a unique number for each entry in the table).
I
These numbers are usually in ascending order in the table, but you can
change the order.
The digit(s) that begin the dial sequence. There can be multiple entries
I
that start with the same digit. Example: If you use extensions that start
with the number 4, and you want to reserve 4567 as the FAX
extension, you could have one entry for 4 and one for 4567. The NBX
100 uses the most specific match.
The minimum number of digits the NBX 100 must collect before
I
making a decision.
Example: If you are using a 4-digit dial plan and the telephone
extensions start with 2, then the table entry with 2 in the Digits
column typically has 4 in the Min column. Before making a decision,
the NBX 100 would collect all 4 digits of the extension.
The maximum number of digits the NBX 100 must collect before
I
making a decision. Often, this value and the Min value are identical, as
is the case for internal extensions.
A call classification (always Internal for the Incoming Dial Plan Table).
I
A priority number (not used at this time, but must be present).
I
A route (identifies a route entry in the Routes section of the Dial Plan).
I
Specifying a route number in this column associates a table entry with
a specific route. Route numbers are pre-defined in the NBX 100. See
Table 7.
By default, Line Card ports, Digital Line Card ports, and H.323 gateways
use the Incoming Dial Plan table as their normal Dial Plan table. An
Incoming Dial Plan table typically has a more restricted list of dialable
digits than the Internal Dial Plan table.
Example: You typically cannot dial extensions associated with internal
paging or analog or digital Line Card ports.
