We have a problem dealing with TDMoIP over ePMP Force 200. We builded scheme like this:
(E1)RAD Ipmux 2L(ETH) - ePMP Force 200 - ePMP Force 200 - (ETH)RAD Ipmux 2L(E1)
All Cambium devices are working in PTP mode and distance between two of them is about 2km. FW version: 3.3. There are 2 tagged vlans on RAD's ethernet ports (one for management, second for TDMoIP traffic). The problem is that synchronization between two RADs constantly falls and there is no OAM connection.
I thought that problem was in noized ether so I made test bench for that problem (distance about 30m, manually limited power on them and so on, but had new devices), but problems still remained. We decided to use Intracom devices (works in 70-80 GHz) and problem gone, but this is unpreferable decision due to expensiveness of Intracom devices.
Is there any way to avoid the loss of synchronization on Cambium devices?
Thanks in advance.
