http://docs.tzafrir.org.il/dahdi-linux/#_procfs_interface_proc_dahdi "Clear" basically means this is an ISDN B-channel. HDLCFCS means this is a D-channel. 'dchan' = 'fcshdlc' . I'll leave aside the issue of 'dchan' vs. hardhdlc because there's actually some chating here. -- Tzafrir Cohen icq#16849755 jabber:[email protected] +972-50-7952406 mailto:[email protected] http://www.xorcom.com iax:[email protected]/tzafrir -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
