Configure FXS port as FXO port

[Alex Deiwor]

Hi,

I have a Cisco 1861 Integrated Services Router with 4 FXS ports and 2BRI.

Well, as it is known, the FSX ports is for telephones, fax, etc.My deal is to connect the router to the PSTN network with a single RTC thru a analog port, but I'm not sure how it's possible because all of them are FXS.

As other hardware manufactures I worked on before, I could deactivate the FXS signal and start configuring as FXO, but i dont know how to make this on Cisco.

Can anyone advice me?

Thank you!

It is not possible to do that. You will need to instal FXO ports.

Hi,

Thank for your quickly reply.

So the option its about to configure in the BRI ports then.

You will need BRI service from telco to use the BRI ports.

Thanks for the nice rating and good luck!
