Use this configuration to connect paging equipment

to the pager. These are generally controllers or
telephone interfaces with controls and settings.

In this configuration, you can specify a paging delay to
compensate for the fixed delay introduced by the OHP
system. This delay ensures that the paging tone is played simultaneously on both Desksets and on the OHP system. See "Single-
Zone Overhead Paging Delay" on page 123.
