Hello.
I have a situation in which I am emulating E1 circuits. Im my enviroment I have 2 MWR 2941 (they have the emulation circuit configured, over GRE) at each site connected to a 3750.
I looped the E1 interface at one site and I connected a traffic generator in the E1 interface at the other site; when I run tests using a traffic generator I get lots of erros, drops, slips, etc. I could not find the problem and after a few weeks someone told to use a ME3800 instead of a 3750. I thought that was a stupid ideia because the only traffic in the switch was from the emulated circuit and the traffic was transparent to the switch; however I gave it a try and I am getting no more errors.
Does anyone know why using a ME3800 solved my problem? I have to explain this to the client.
Thanks,
João.
P.S. - I am using PTP with two GPS clocks (one at each site) in all equipements (including de traffic generator) because of clock rate issues.
