That means the Soekris can only handle part of a T1, it will never handle a quad span. Paul How was that determined? I have a problem with a plain number like that, which may have been taken into account, why I am asking... Different cpus operate differently, taking more or less time to complete certain functions. Instruction optimization can go a long way if those instructions are used (not terribly likely if its just pushing bits but there are some for just that). Additionally there is no codec processing (presumably) with TDMoE, does the 30MHz take into account any codec processing or is it literally 30MHz (on what cpu class?!) for just pushing bits? There are other factors, but you did say 'about' so they are optional to this conversation, ie other IRQs on the box, potential for device polling, etc. A tuned system for that specific task (pushing bits between a TDM card and ethernet via TDMoE) may be able to operate at a lower clock speed per channel, but that isnt as important for the initial questions. _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users MHZ is not a valid way of gauging performance.  It's all about the MIPS (Millions of Instrictions Per Second), Baby :). I was testing with some of the Soekris boards about a year ago for an client, the need was to make a TDMoE -> TDMoE router for a wireless network. (Yes I know that that is a stupid idea, and I told the client that it was a waist of his money to have me try.) the board I was using I think was the 4801, not sure thoe (It was a year ago) but it would pust 48 TDMoE channels at once over 100BaseT ok.  So I would think that It would.  I was using a customized linux distro, (as in one I created) contact me off list if you would like a copy of the distro. -- Christopher Dobbs Wireless Administrator Valario Inovations
