Note Cisco offers two other methods of connecting KEMs to your phone in case you either have a shortage of
desk space that prevents you from using the spine connectors as shown in
Figure 4-2, or in case you need
access to the speaker and microphone ports (on the Cisco Unified IP Phone 9951 and 9971) that the KEM
spine connector covers up. For more information, see the
“Other Methods for Connecting KEMs to the
Phone” section on page 4-5.
