Connecting the 
Telephone
Although the connector layout varies between telephones, all NBX 
telephones and attendant consoles use these symbols to identify the 
connectors:

component on NBX 3101 and 3102 Telephones and the 3105 Attendant 
Console.
Network connection. Connects the device to the network. NBX 3101 and 
3102 Telephones and the 3105 Attendant Console, as well as older NBX 
telephones that include “PE” in the part number, can accept a powered 
Ethernet cable that conforms to the Power over Ethernet (IEEE 802.3af) 
standard.
Switch port for connecting a computer or other network device, such as an 
NBX Attendant Console, to the network.
