We have a GDS3710 intercom unit at a remote gate on our property. It is connected to a network switch in a far room of our house with a PoE injector just after the switch. Until now we have been taking calls (bell push) from the GDS3710 on PCs wired into the network or mobile phones via wifi.
Have just purchased a GSC3570 unit that we will install in the kitchen which is at the ‘near end’ of the house.
We have cat6 cable running: Switch > PoE injector > through internal wiring to the kitchen > then outside for ~80m to the GDS3710 at the gate.
There is a join in the cat6 cable in the kitchen at the point where we want to install the GDS3710 control unit (the wiring was installed for an older system 12–15 years ago, before we bought the house).
My question is … can we ‘cut’ the cat6 cable at the existing join and plug the cable coming from the switch & PoE injector into the “PoE” RJ45 port on the GDS3710, and the other part of the cable that continues out to the gate into the second RJ45 port on the GDS3710. So the final arrangement would be
Switch > PoE injector > ‘PoE’ RJ45-GSC3570-RJ45 > GDS3710
This would greatly simplify installation of the GSC3570 if it can work that way. We have concrete block exterior walls and a concrete floor slab and it would be very difficult to change or add further internal cabling.
Ideally the GSC3570 should bridge power from the injector through to the gate unit as well as providing separate Switch to GDS3710, and Switch to GSC3570 data links. Plus power the GSC3570 of course.
We want it all to go back to the switch so we can continue to respond to the GDS3710 on our mobile phones (via wifi)
My reasons for thinking (hoping!) it can are:
- the GSC3570 documentation describes them as dual switched network ports
- that it would be an obvious use case for the dual network ports?
- one option we investigated previously was an Akuvox IT82R control station/monitor. That also has “dual switched network ports” and the Akuvox agents confirmed to us that the arrangement described above will work with the IT82R (& indeed is an intended application)
My reason for fearing it might not work is that none of the Grandstream documentation and application examples I have seen show the GDS3710 and GSC3570 connected this way. Almost all examples show the GDS3710 and GSC3570 independently connected to a switch via separate network cables or wifi links.
Would very much appreciate clarification on the above.
