That depends on the environment This is what i have read b4 about t1 timing srcs 1. If the T1 is point to point where both ends terminate on a different * boxs. Then one of the T100p supplies clock for the other . The network, unless other wise designed, will not supply clock to the T1 2. If the T1 originates from a PRI or channel bank, switch, etc, then the network supplies clock UNLESS the t100p can supply a T1 clock source traceable to a Stratum 1 Primary Reference Source (PRS) , then the T100 can supply clock back to the T1.. see here for a defintion of stratum src http://www.raltron.com/products/pdfspecs/sync_an02-StratumLevelDefined.pdf I am sure the clock on the digium h/w is not Stratum 1 :) Its is probably a Stratum 4 TTL oscillator... I think there are only a few Stratum 1 src in the NorthAmerica big $$$$. If your just clocking a channel bank it maybe a toss up who has the the best timing src, but some might have a Stratum 3 certifed src ?? >From what I have read most telcos have Stratum 2 or 3 devices as backup but get an outside feed from a bonfide Stratum 1 src _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
