Cable Specifications

The following information lists the cable specifications:

  • RJ-9 jack (4-conductor) for handset and headset connection
  • RJ-45 jack for the LAN 10/100/1000BaseT connection (10/100/1000 Network port on the Cisco Unified IP Phone 8961, 9951, and 9971)
  • RJ-45 jack for a second 10/100/1000BaseT compliant connection (10/100/1000 Computer port on the Cisco Unified IP Phone 8961, 9951, and 9971)
  • 3.5 mm jack for microphone and speaker connection (for Cisco Unified IP Phone 9951 and 9971 only)
  • 48-volt power connector

Network and Computer Port Pinouts

Although both the network and computer (access) ports are used for network connectivity, they serve different purposes and have different port pinouts.

  • The network port is the 10/100/1000 SW port on the Cisco Unified IP Phone.
  • The computer (access) port is the 10/100/1000 PC port on the Cisco Unified IP Phone.
