The extensions that the system assigned to these ports might not be in
order. For example, if the system assigns extensions 7258, 7259, 7260,
and 7261 to the ATC ports, it might assign 7258 to port 3.
To determine which extension is associated with a given port, click
Telephone Configuration > ATA and examine the list of ATAs and ATC
ports. For example, to determine the extension assigned to the third port,
look for the ATC port with a MAC address that is two hexadecimal digits
higher than the MAC address of the board. The extension of the port is in
the first column (Extension).
After you add the Analog Terminal Card, you can configure the
parameters for each of the four ports. See
Terminal Port" on page
Extension Assignments (3C10117C ATC)
On a 3C10117C Analog Terminal Card, there is only one MAC address.
Each of the four ports is assigned a unique virtual device number
(1 through 4) so that the system software can address each port
separately.
When you click Telephone Configuration > ATA to view the information,
the system displays the port number, enclosed within square brackets,
after the MAC address. See

The extensions that are assigned to these ports by the system might not
be in order. For example, if the system assigns extensions 7258, 7259,
7260, and 7261 to the ATC ports, it might assign 7258 to port 3.
