 The voice switch patch panel provides a flexible cable management solution for the voice
switches. The patch panel has RJ-21X connections running to the voice switches and RJ-11
connections on the front.
Starting from the right in Figure 43 on page 252, the trunk cabling is organized as follows:
 The digital (T1/E1) and analog trunks are terminated on a punch-down block.
 The digital service is further terminated at a service provider demark with an RJ-48 connector.
 An RJ-48 cable from the T1/E1 demark connects to the ShoreTel T1 or ShoreTel E1.
 The analog service is cross-connected to a modular (RJ-21X) punch-down block.
 A telco cable is connected to the modular (RJ-21X) punch-down jack and runs to a modular
connector (RJ-21X) on an analog trunk patch panel.
 Like the telephone cabling, patch cords are connected from the analog trunk patch panel (RJ-11)
to the voice switch patch panel (RJ-11).
As an alternative, patch panels can be replaced with punch-down blocks. This may be more cost-
effective but is less flexible.
