Re: Centrex

If the analog lines are terminating on your centrex, you can have either digital or analog lines going form the centrex to the router. For Analog you can have E&M, FXS or FXO lines interfacing with the router. With digital you can do either ISDN signalling or CAS between the router and the carrier. That would involve a T1 coming form the carrier to the router. Depending on the number of users and the requirements, you could go either way.
