CO Demand Diagnostic Test (#3)
For ground start trunks, circuit pack or media module port relays are operated and checks are
made to see if the port can detect and apply ground on the Tip lead. This test also verifies that
there is no external ground on the Ring lead. In the absence of other failures, the circuit pack or
media module should be replaced only if this test fails with the CO line disconnected.
This test also checks the on-board programmable transmission circuits that allow the circuit
pack or media module to support transmission characteristics of several different countries.
PASS Trunk was seized, and dial tone was detected. User-reported troubles on
this port should be investigated by using other port tests and by examining
trunk or external wiring.
