Connecting and 
Managing Analog 
DevicesA 4-Port Analog Terminal Card or a Single-Port Analog Terminal Adapter 
(ATA) allows ordinary analog (2500-series compliant) telephones, 
including cordless telephones and Group-3 facsimile devices, to operate 
with NBX systems.
Certain limitations apply because of the differences between an analog 
device and the custom NBX Telephone: 
■A user dials 500, then ** on a telephone connected to an ATA to gain 
access to voice mail.

Extension Assignments (3C10117 ATC)
Each of the four ports on a 3C10117 Analog Terminal Adapter 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...

224CHAPTER 3: DEVICE CONFIGURATION
The extensions that are 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 the extension assigned to any port on a 3C10117C ATC:
1Click the ATA tab.
2Look for the combination of MAC address and port number that you 
want. The extension associated with the port is in the first column (Ext.).
After you have added the...
