the extension jack change on Form 2a, System Numbering: Extension
Jacks. See Appendix B, "System Numbering Forms," for details.
2. Private Network problems (Release 6.0 and later, Hybrid/PBX mode)
are generally caused by incorrect programming. When attempting to
isolate a private network problem following the guidelines here, see
"Network Calling Problems" on page 5–40.
