How to determine the NAM (Norstar Application Module) serial number... (or, just access the NAM programming, in general)
The serial number is checked as follows:
Feature 915 (If F915 does not give a “Password” prompt, try feature codes from
F910 to F949 until you do get a “Password” prompt)
"Password” - enter 2223772# (ACCESS2)
“ACCESS Server” – press ADMIN
“A. Prt queue mgr” – press NEXT 8 times
“I. Serial Number” – press SHOW
“S#: XXXXXXXX” – record the serial number and press OK
