Understanding the Cisco Unified IP Phone 7965G and 7945G Components

Network and Access Ports

The back of the Cisco Unified IP Phone includes these ports:
•
•
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
Power to the Phone" section on page 2-3
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 Cisco Unified IP Phone 7965G and
7945G.
You can disable the speakerphone through the Cisco Unified Communications Manager Administration
application. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone
Configuration web page 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
