Recommendation for Analog ext over long distance

[Antwis79]

Have a small key system installation with Analog call boxes. 2 of them are over the maximum distance allowed. Any recommendations on a ethernet to analog adapter?

Here is the one I recommend. Easy to set up, and they work

Would be good to know the length of the loops. Not sure if a Sip ata fxo/fxs combo could extend to your need or whether some Viking LLA-1 long loop adapters might be needed. Both assume copper is presently there between locations.

You ask about ethernet to analogue adaptors, what do you mean by this? Are you meaning using SIP extensions or just converting analogue to ethernet then back to analogue? For that matter what small key system do you have, is it even an NEC system?

If they are all on premises, you may be able to just double up on the pairs to reduce the loop resistance.
