Allowed Digit Maps
You can create/edit ten digit maps for the Mediatrix 4104. Digit map rules are checked sequentially. If a
telephone number potentially matches two of the rules, the first rule encountered is applied.

To set up digit maps:
1. In the Allowed Digit Map section – Activation column, enable one or more digit maps by selecting
the corresponding Enable choice.
Figure 36: Allowed Digit Map Section
2. Define the digit map string that is considered valid when dialed in the Digit Map column.
The string must use the syntax described in “Digit Maps” on page 71 . A digit map string may have
a maximum of 64 characters.
3. Define the amount of digits to remove from the beginning of the dialed number, after dialing, but
before initiating the call, in the
Remove Prefix column.
For instance, when dialing “1-819-xxx-xxxx”, specifying a value of “4” means that the call is started
by using the number “xxx-xxxx”.
This rule is applied BEFORE applying both the Add Prefix (Step 4) and Remove Suffix (Step 5)
rules.
4. Define the string to insert at the beginning of the dialed number before initiating the call in the Add
Prefix column.
For instance, let’s say that you need to dial a special digit, “9”, for all local calls. Dialing “xxx-xxxx”
with a value of “9” would yield “9-xxx-xxxx” as the number with which to initiate the call.
This rule is applied AFTER applying both the Remove Prefix (Step 3) and Remove Suffix (Step 5)
rules.
5. Define the string to look for and remove, from the end of the dialed number, in the Remove Suffix
column.
This is helpful if one of the digit maps contains a terminating character that must not be dialed.
For instance, in a digit map such as “25#”, the “#” signals that the user has finished entering digits.
To remove the “#”, specify “
# ” in this field and the resulting number is “25”.
This rule is applied AFTER applying the Remove Prefix (Step 3) rule, but BEFORE applying Add
the Prefix (Step 4) rule.
6. Specify the line(s) on which to apply the digit map in the Line To Apply column.
The string has the following syntax:
• all : Applies to all lines.
