This are D-channel Layer 2 recovered errors, they are quite normal from time to time but there is something wrong when they appear massively. > > Jan 3 22:57:07 <kern.crit> radi /kernel: i4b-L1 itjc_dma_rx_intr: CRC (crc=0x00 > > 97, len=322, unit=0) This is a layer one error from the hardware driver. It may appear when the Layer 1 is being shut off or started. > It can also be related to a problem that occurs on my machine: > on almost every connection establishment I get a "i4b-L2 T200_timeout" > or a "i4b-L2 T202_timeout". This is strange and should be looked after. Sergio, perhaps you should get yourself the Q.921 european equivalent ETS 300 125 describing the timers and the whole layer 2 implementation, its available free of charge from www.etsi.org. Just for completeness, perhaps you might want to get ETS 300 012 for the layer 1 (this affects every i4b hardware driver writer) which is the european version of I.430 and ETS 300 403-1 and ETS 300 403-2 for the layer 3 which are the european version of Q.931. hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
