Tieline with Analog trunks

[aau2]

Hi everybody. My boss wants join our MD110 with a trunking system, wwe have proved different configurations of the route, but it doesn´t work.
Is it possible that a TLU75 gives 48V DC?
Any idea of the configuration of the route?

Thanks.

Here you need a TLU21 ( DC tieline ) or TLU25 ( CB line ),
but I think you can use a analog extension interface, it's depend on the other site.

The problem is that we want configure the trunk with the TETRA system as a route, no as a extenssion.
Any experience with TETRA systems?
