Permanent Administrative State
The permanent administrative state is applied every time the Mediatrix 1204 restarts.
X
To set a permanent administrative state:
1. In the ifAdminMIB , locate the ifAdminInitialAdminState variable.
This variable indicates the administrative state the current analog line will have after the Mediatrix
1204 restarts. It offers the following settings:
Line Grouping
A group is a collection of analog lines that, when called from the IP network, behave as if they were only one
line. It’s the same principle as calling a call centre, where there is only one telephone number, but there are
several telephones on the call centre side. An algorithm allows to choose the line to use upon a new incoming
call.
Currently, there is only one group that contains all the FXO lines. Future versions of the Mediatrix 1204 will
allow you to define additional groups.
Source Line Selection
The source line selection feature defines a list of callers that have the right to use a specific FXO line to make
a call. This feature can be used to map an FXS line of an access device such as the Mediatrix 1104 to a
specific FXO line of the Mediatrix 1204. See
“Examples of Source Line Selection Use” on page 197 for more
details.
X
To set the line selection:
1. In the lineSelectionMIB , define the list of telephone numbers that can use this line to make calls in
the lineSelectionDigitMap variable.
IP to SCN call sources that match this digit map can use this line. This string must follow the syntax
for digit maps (see
“Chapter 21 - Digit Maps” on page 243 ). This digit map will not have any effect
unless the feature’s status is “enabled”.
Because this variable is located in a table, you can define different digit maps for each line of the
Mediatrix 1204.
2. Enable the line selection feature by setting the lineSelectionEnable variable to enable .
The source of the call is compared to all the source line selection digit maps defined in the previous
step. The result of this comparison is a list of lines that can take the call, but are not necessarily
available to do so.
Once the match list has been created, there are two possibilities:
• The list contains one or more lines. The line selection algorithm selects a line. If none of
the lines in the list are available, the call is rejected. See
“Line Selection Algorithm” on
page 198 for details.
