Commands 6-33Octel Overture 200/300 Serenade 3.0PB60014–01Ring Detection/ PBX Connection TestUse the TEST LINE 4 command for this test. To run the test, turn on the terminal or teleprinter. At the@ prompt, typeTE L 4 x For this command, x is the installed port number (in HEX) to be tested.This test runs only on the port requested in the command, and the port must have the self-test parameterin the SLOT Table set to YES.This port is rapidly seized and released repeatedly. This action causes charging and discharging of thetip-and-ring circuitry on the LIC, if the port is correctly connected to the PBX. These pulses trigger thering-detection circuitry on the port.The test is completed successfully when the LIC reports the detection of this “ringing” to the CPU. Ifringing is not detected, the test terminates unsuccessfully after 5 seconds and leaves the tested port in theTST mode, removing the port from service. An error is also logged in the Hardware Error Table. Some PBXs are not capable of generating sufficient voltage or loop current quickly enough for thetest to succeed. One example is the Northern Telecom SL1. Consult with Technical Support if youare uncertain whether a particular PBX supports this test.Ring-Through TestThe ring-through test is run only on demand and should be used only when the Octel Overture 200/300is initially installed or when it is known that no calls are being processed.The ring-through test performs the following sequence:1. Seizes a port2. Waits for dial tone from the PBX3. Sends digits to a port using the extension number entered in the SLOTS Table4. Waits for the port to answer, and sends a test patternFor example, a four-port message server makes 12 test calls; each test call takes 20 to 30 seconds tocomplete. If the port called is busy or does not answer, an error is logged in the Hardware Error Table.The command for this test is TEST LINE 2. To initiate the test, at the @ prompt, typeTE L 2 Update IntegrationThe following changes to integration slots require that the integration cards be restarted before thechanges take effect: Adding or deleting integration slots Modifying line appearances for an integration slot Enabling or disabling message waiting links
