200 CHAPTER 3: DEVICE CONFIGURATION
Extension Assignments (3C10117 ATC)
Each of the four ports on a 3C10117 Analog Terminal Card has a MAC
address. The first port has the same MAC address as the card, and the
remaining three ports have sequential MAC addresses incremented by
one hexadecimal digit. See Table 36
:
The extensions assigned to these ports by the NBX system may not be in
order. For example, if the NBX 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, you must
access the ATA tab in the NBX NetSet utility 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 (Ext.).
After you have added the Analog Terminal Card, you can configure the
parameters for each of the four ports. See “
Modifying an Analog
Terminal Port” on page 203.
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 NBX software can address each port separately.
When you select the ATA tab, and view the information, the port number
appears after the MAC address, enclosed within square brackets.
See Table 37
.
