Avaya Availability Analysis

Found an interesting document in my archive:

Avaya Platform Elements


Mean Time To Failure

Media Processor Board ** 35 years
Protocol Preprocessor Board (C-LAN) ** 50 years
Digital Line and Trunk Boards ** 72-77 years
Avaya Media Server Complexes 10-90+ years
Avaya Gateway Power Supplies ** 25-60 years

** Based on numerous internal Avaya studies assessing the results of millions of user-hours.

Nice, isn’t it? It must be especially heartening to know this when you’re out there in the field, replacing another faulty TN464.

Here’s the next part:

May be useful for preparing RFPs or alike documents.
