	and Preparation

Before troubleshooting problems, obtain copies of your system’s planning forms. Many of the solutions offered in this chapter require that you contact the coordinating system manager in your private network, who maintains records of how systems in your private network are programmed and keeps them up to date. Problems can occur when changes are made in a private network without considering the needs of the private network as a whole. In particular, changes to local and non-local dial plans, Uniform Dial Plan (UDP) routes, Automatic Route Selection (ARS) routes, and remote access settings can have unintended effects on other systems in your private network.

To solve a problem, you may need to perform system programming using your

MLX-20L programming console or PC equipped with System Programming and

Maintenance (SPM) software.

Most of the problems outlined here can be solved by system managers working together in a two system private network or with the coordinating system manager in a larger private network. However, some problems require the intervention of a Lucent Technologies technician. In the USA only, Lucent Technologies provides a toll-free customer Helpline (1 800 628-2888) 24 hours a day. You may want to allow only the coordinating system manager to contact the Helpline, because this person has the complete information that allows Lucent Technologies technicians to understand problems that you are experiencing. Under certain circumstances, you may be charged for consultation with Helpline personnel. Contact your Lucent Technologies representative or authorized dealer, if you have any questions concerning consultation charges.

The troubleshooting instructions in this chapter provide information about reviewing current programming on your local system. You can find out about current programming in the following three ways:

■System Forms. Review the filled-out system form that includes the programming information you need. This method requires that forms be available and up-to-date.

■System Reports. Appendix B, “Sample Reports,” includes samples of reports that you may require when troubleshooting private network problems, along with the menu options for selecting each report. To see a report, select the 3ULQW option on the System Programming menu and then choose a report. The Feature Reference, Appendix F, includes samples of all system reports.

■System Programming. Many of the system programming procedures that you may need to perform are summarized in Chapter 5, “Network Management.” System Programming includes instructions for accessing system programming by using the MLX-20L console or SPM software on a personal computer. The troubleshooting instructions also cite procedures from System Programming.
