If there are no direct connect pstn links (eg, T1/E1) to sync from, then pick "something" and call it your clock-sync source. It really doesn't make much difference what kind of box it happens to be. The md110 is just as good a source as probably other boxen in your environment. If there are multiple asterisk boxes connected together via T1/E1's, I'd pick a box that is easy to access with the thought process that sooner or later the asterisk box _might_ get a direct pstn T1/E1 making the change to sync from it easier (in the future). I would also pick a box to sync from that, in your best judgement, would be the stablist clock. That would likely be some commercial, well established, and reliable box as opposed to some off-the-wall thing that may not be the most stable thing on earth. ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

All T1/E1 data links of any type require sync. All T1/E1 links have timing/sync included in their transmit leg and there is no way for you to turn it off. Its part of the T1/E1 spec. If you don't have any T1/E1 connections to the outside world, then pick one channel bank and call it your official source of sync, and change the above definitions to sync off that channel bank. On all other channel banks, configure them to sync off the asterisk card. If you do have a T1/E1 that comes from your telco/pstn network, use it as the source of clock sync, and config all channel banks to sync from asterisk. Your clicks will go away. ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
[Asterisk-Users] Clicks, pops and noise
Hi all, I've got a TE410p connected via T1 to four channel banks (2 FXO and 2 FXS), no PRIs. Some users are complaining that they hear clicks and pops on the FXS lines, generally when they pick up the phone it's noisy. This happens only after a while, e.g. after a fresh restart of everything, all is fine but after some time these noises start appearing. From what I've read on the list, this could be down to frame slips or some problem due to synchronization. Since there's no incoming PRI to sync to, this means everything needs to be internally clocked. Could it be the internal clock source on the card has gone wonky? Or is something else in the server screwing up the clock signal? Anyone else experienced this when connecting four channel banks to the TE410? Zaptel.conf: span=1,0,0,esf,b8zs fxsks=1-24 span=2,0,0,esf,b8zs fxsks=25-48 span=3,0,0,esf,b8zs fxsls=49-72 span=4,0,0,esf,b8zs fxsls=73-96 TIA, flynn ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
