We are using the zaptel driver to deliver a combined voice/data T1 circuit.
The data channel-group is using the "cisco" hdlc protocol (on the linux side) and connects with a cisco router on the far side. Everything comes up and works fine for a while. A while later, though, IP communication fails completely. The cisco side shows up/up. The Linux side has a message in the log file stating: "hdlc0: Link down". Just prior to the link down message are numerous messages that say "New offset:" followed by different numbers. That may or may not be relevent. I am curious to know other people results with this configuration, if any. If you had the same problem, how did you solve it? We are planning to switch to PPP and see if that improves the situation. --Nick (implementation details follow:) CISCO: interface Serial1/0:1 ip address 1.0.0.102 255.255.255.252 encapsulation hdlc end LINUX: sethdlc hdlc0 mode cisco ifconfig hdlc0 1.0.0.101 netmask 255.255.255.252 OS: Redhat 8.0 Kernel: 2.4.18-27.8.0 /etc/zaptel.conf: loadzone=us defaultzone=us span=1,1,0,esf,b8zs nethdlc=1-6 bchan=13-23 dchan=24 ZAPTEL driver CVS diff: cvs server: Diffing .
