Lines Administrative State
You can independently set the administrative state of each analog line of your Mediatrix 4100. This state
determines how the Mediatrix 4100 processes calls.
For instance, you must properly unlock the analog lines of the Mediatrix 4100 to properly make and receive
calls on all of them.
The administrative states may be applied in two ways:
 Temporary: The administrative state is applied immediately, but it is not kept after the Mediatrix
4100 restarts.
 Permanent: When the Mediatrix 4100 restarts, it reads a MIB variable to determine the
administrative state defined for each analog line.
Temporary Administrative State
You can set the administrative state of a line that will be kept until the Mediatrix 4100 restarts. Once the unit
restarts, it uses the permanent state defined for each line. See “Permanent Administrative State” on page 130
for more details.
 To set a temporary administrative state:
1. In the ifAdminMIB, locate the ifAdminSetAdmin variable.
This variable temporary locks/unlocks the selected line of the Mediatrix 4100. This state is kept until
the unit restarts. It offers the following settings:
In the Unit Manager Network Administration Manual, refer to chapter Ports Parameters, section Port
