The TEI is the "address" of a device on the S0 bus and uniqely identifies a device. Or even, it is the address of a unique instance in a physical device - a physical device may have more than one TEI assigned to it. A TEI is a layer 2 concept. The Call Reference uniqely identifies a single call control transaction on a given S0 bus. IIRC there may be even the same CR's used for incoming and outgoing calls because the direction is encoded in the CR information element (as this was a fat bug in i4b). A CR is a layer 3 concept. hellmuth -- Hellmuth Michaelis Tel +49 40 559747-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 559747-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de 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
