Description
Table entry number (a unique number for each entry in the table). Typically, these numbers
are in ascending order in the table, but you can change the order. For example, you might
want to place a new item near other items of the same type (that begin with the same digit)
to help troubleshoot the configuration file.
One or more digits that begin the dial sequence. Either single or multiple entries can start
with the same digit. The system uses this field with the Min and Max fields to determine
when to make the call routing decision.
Most sample tables have a single entry for digit 0 (zero) to specify how the system manages a
telephone number with zero as the first digit.
If you want the system to manage calls differently, depending on whether they start with 90
or 91, you must have one entry in the table for each of these 2-digit sequences.
Minimum number of digits that the system collects before routing the call.
Maximum number of digits the system collects before routing a call.
Class of Service (CoS). The system uses this information to determine whether a caller is
allowed to make this specific type of call. The possible classifications are:
Internal, Local, LongDistance, International, WAN, Toll- Free, Emergency, COCode,
Wireless, Toll, Operator, AlternateLong, TrunkToTrunk, Diagnostics, NotAllowed, Other
Each of these values corresponds to a selection in the NBX NetSet utility.
Priority number. This field is not used at this time, but must be present and must always be 0
(zero).
Route number. This identifies an entry in the Routes section of the dial plan. Zero is a typical
value for internal calls, and indicates that this call uses no route, in which case, the system
transmits the digits as soon as the caller dials them.
If a new entry in the Internal table does not work, it is possible that the
system is using an entry from the Least Cost table instead. To avoid such
conflicts, you can achieve least cost routing using only the Internal table.
To keep the dial plan as simple as possible, 3Com strongly recommends
that, you use only the Internal table for least cost routing.

Basic Dial Plan Table Examples
These examples describe the basic operation of a dial plan table.
Example: If you use 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 determination, the system collects all 4
on page 273.
