Yes. I would be interested in hearing about how big of a restriction this is in practise? If we put two quad-E1 cards in each of two boxes set up in a cluster configuration, that is already 123*4 = 492 bearer channels (reserving two for signalling). So with redundancy, in a failover scenario one signalling link would be serving around 500 bearer channels. Is that a limitation in practise? How many bearer channels can one reasonably run on a single signalling link? Also wonder if it is possible to put in more bearers in a single box? - Kristian. -- Kristian Nielsen, Software Developer MySQL AB, Hvidovre, Denmark, www.mysql.com Office: +46 18 174 400 ext. 4525 Are you MySQL certified? www.mysql.com/certification
