Understanding the Cisco Unified IP Phone 7965G and 7945G Components Chapter 3 Setting Up the Cisco Unified IP Phone Network and Access Ports The back of the Cisco Unified IP Phone includes these ports: • Network port-Labeled 10/100/1000 SW on the Cisco Unified IP Phone 7965G and 7945G • Access port-Labeled 10/100/1000 PC on the Cisco Unified IP Phone 7965G and 7945G You can use either Category 3/5/5e/6 cabling for 10 Mbps connections, but you must use Category 5/5e/6 for 100 Mbps connections and Category 5e/6 for 1000 Mbps connections. Use the SW network port to connect the phone to the network. You must use a straight-through cable on this port. The phone can also obtain inline power from a switch over this connection. See the "Providing Power to the Phone" section on page 2-3 for details. Use the PC access port to connect a network device, such as a computer, to the phone. You must use a straight-through cable on this port. Handset The wideband-capable handset is designed especially for use with a Cisco Unified IP Phone. It includes a light strip that indicates incoming calls and voice messages waiting. To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and into the Handset port on the back of the phone. Speakerphone By default, the wideband-capable speakerphone is enabled on the Cisco Unified IP Phone. You can disable the speakerphone by using Cisco Unified Communications Manager Administration. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone Configuration window for the phone, check the Disable Speakerphone check box. Headset Although Cisco Systems performs some internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco does not certify or support products from headset or handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed, there is not a single "best" solution that is optimal for all environments. Cisco recommends that customers test the headsets that work best in their environment before deploying a large number of units in their network. In some instances, the mechanics or electronics of various headsets can cause a remote party to hear a voice echo when speaking to a Cisco Unified IP Phone user. Cisco Systems recommends the use of good quality headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and their proximity to other devices, such as cell phones and two-way radios, some audio noise may still occur. The primary reason that support of a headset would be inappropriate for an installation is the potential for an audible hum. This hum can either be heard by the remote party or by both the remote party and the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range Cisco Unified IP Phone 7965G and 7945G Administration Guide for Cisco Unified Communications Manager 6.1 3-4 OL-14641-01
