[Asterisk-Users] Channel Restart - problem with Asterisk spliced between Arcor E1-PRI and Ericsson BP250
hi, well, most of the things work right now due to the help of peter svensson, but after heavy use of our ericsson BP250 today several problems appeared. i split into several mails as they are seperate problems. * from time to time (sometime within a few minutes sometime after hours) a complete PRI line or several PRI lines are kind of resetting (none of my colleagues reported a call interruption though). could this be a problem of the length (around 4kilometres) of the line between the telco switch and the NT providing the E1-PRI? The PRI line itself is only 3 metres long. is this the line build-out parameter in /etc/zaptel.conf? or is this something with timing of the span? my current settings are: # The line build-out (or LBO) is an integer, from the following table: # 0: 0 db (CSU) / 0-133 feet (DSX-1) # 1: 133-266 feet (DSX-1) # 2: 266-399 feet (DSX-1) # 3: 399-533 feet (DSX-1) # 4: 533-655 feet (DSX-1) # 5: -7.5db (CSU) # 6: -15db (CSU) # 7: -22.5db (CSU) # TE405P/TE410P quad E1 span=2,1,0,ccs,hdb3,crc4 bchan=5-19,21-35 dchan=20 span=3,0,0,ccs,hdb3,crc4 bchan=36-50,52-66 dchan=51 span=4,2,0,ccs,hdb3,crc4 bchan=67-81,83-97 dchan=82 span=5,0,0,ccs,hdb3,crc4 bchan=98-112,114-128 dchan=113 this is a excerpt from /var/log/asterisk/full -- B-channel 0/1 successfully restarted on span 2 -- B-channel 0/3 successfully restarted on span 2 -- B-channel 0/5 successfully restarted on span 2 -- B-channel 0/6 successfully restarted on span 2 -- B-channel 0/7 successfully restarted on span 2 -- B-channel 0/8 successfully restarted on span 2 -- B-channel 0/9 successfully restarted on span 2 -- B-channel 0/10 successfully restarted on span 2 -- B-channel 0/11 successfully restarted on span 2 -- B-channel 0/12 successfully restarted on span 2 -- B-channel 0/13 successfully restarted on span 2 -- B-channel 0/14 successfully restarted on span 2 -- B-channel 0/17 successfully restarted on span 2 -- B-channel 0/18 successfully restarted on span 2 -- B-channel 0/19 successfully restarted on span 2 -- B-channel 0/20 successfully restarted on span 2 -- B-channel 0/21 successfully restarted on span 2 -- B-channel 0/22 successfully restarted on span 2 -- B-channel 0/23 successfully restarted on span 2 -- B-channel 0/24 successfully restarted on span 2 -- B-channel 0/25 successfully restarted on span 2 -- B-channel 0/26 successfully restarted on span 2 -- B-channel 0/27 successfully restarted on span 2 -- B-channel 0/28 successfully restarted on span 2 -- B-channel 0/29 successfully restarted on span 2 -- B-channel 0/30 successfully restarted on span 2 -- B-channel 0/31 successfully restarted on span 2 regards frank sautter

[Asterisk-Users] Channel Restart - problem with Asterisk spliced between Arcor E1-PRI and Ericsson BP250
Hi, restarting the B channels is a normal process on PRIs. Nothing to worry about as long only idle B channels are restarted. best regards Klaus Am Donnerstag, den 27.01.2005, 13:10 +0100 schrieb Frank Sautter:> hi, > > well, most of the things work right now due to the help of peter > svensson, but after heavy use of our ericsson BP250 today several > problems appeared. > i split into several mails as they are seperate problems. > > * from time to time (sometime within a few minutes sometime after hours) > a complete PRI line or several PRI lines are kind of resetting (none of > my colleagues reported a call interruption though). > could this be a problem of the length (around 4kilometres) of the line > between the telco switch and the NT providing the E1-PRI?

This is normally harmless and prevents the two ends from getting out of sync. On some remote ends (PAnasonic PRIs e.g.) due to bugs this can be a problem. If there has been no reports of dropped calls there should be no need to worry. Peter
