Avaya 03-300430 User Manual

The circuit packs listed below provide 16 analog line ports for single-line voice terminals. The 
table below indicates which circuit packs are equipped with lightning protection (for 
off-premises, out-of -building stations), and which ones support the neon message waiting lamp 
feature.

These circuit packs provide 16 ports for analog voice terminals. The TN746, TN468, and TN749 
support only single-line, on-premises/in-building, analog voice terminals, and not off-premises 
stations, since these circuit packs are not equipped with lightning protection. The TN746B, 
TN2144, TN2149, and TN468B support both on-premises and off-premises (that is, 
out-of-building) analog voice terminals. The TN468, TN468B, TN479, TN2135, TN2144, and 
TN2149 do NOT support the neon message waiting feature.

No maintenance of the terminal connected to the 16-Port Neon Analog Line circuit pack is 
performed, except to determine whether or not the terminal is connected. Failures of the neon 
message waiting lamp power and the common ringing application circuitry are reported as part 
of common port circuit pack errors; see errors 1281 and 1793 in
