networking parameters if DHCP or BOOTP is not being used.

The diagram in Figure 43 highlights the key components with respect to cabling for your voice network.
Figure 43: Cabling Overview
Starting from the lower left in this diagram, the telephone cabling is organized as follows:
 A telephone jack (RJ-11) is provided for each telephone.
 Telephone cabling (Category 3 or better) is terminated on the telephone jack and runs back to the
equipment room to a modular connector (RJ-21X) on a telephone patch panel.
 The telephone patch panel provides a flexible cable management solution for the telephone
cabling. The patch panel has RJ-21X connections for the telephone cabling and RJ-11
connections on the front.
 Patch cords are connected from the telephone patch panel (RJ-11) to the voice switch patch panel
(RJ-11).
