MLX Phone Mis-Identifcation

[itcmerlin]

I have another interesting question. When I connect a MLX-16DP phone to our Legend PBX, the PBX recognizes it as a MLX-28. The other types of digital phones (MLX-10 and MLX-20L) are recognized properly.

Any ideas as to why this is and if it can be corrected?

They always do. It is normal. Just program the correct buttons. there are diagrams in the manual.

The reason why, is because it has the wrong board inside the set. I had that happen a few years ago, when adding MLX16DP sets to a system. Of the 12 phones added, 4 show as MLX28 sets. The supplier replaced them, since they were under warranty. The refurbisher probably put the wrong one in them at the time the sets were rebuilt.

Here it is Right from the R7 Manual

For each specified station (extension): type of
equipment connected, features assigned, ESS
supervisor status, and features assigned to
each button. On this report, MLX-16DP
telephones are reported as MLX-28D . As of
Release 5.0, MLX-5 and MLX-5D telephones
are reported as 5-button telephone sets. In
releases prior to Release 5.0, MLX-5 and MLX-
5D telephones are reported as MLX-10 and
MLX-10D telephones, respectively

Which R7 document and page number? There are six plus documents!

This will even happen AFTER you've upgraded an older Legend to a Magix. Therefore it's a problem at the electronics level, not the software level.

Manufacturers use flip-flops, resistors...all kinds of things to add a "signature" to a telephone for identification purposes. But due to wire lengths, gauge, old hardware and such, there may be a mis-identification.

It could also be that the MLX-16 and MLX-28 were developed with such distance between them that it never made sense to go back and re-develop the supporting MLX board such that it could distinguish the two.

Note though that the 44xx series phones are never mis-identified.
