At a previous employer we used AS5300s with DS3 interfaces as the PRI gateways for our Broadworks platform, straight from TDM to SIP. I am not sure what the modern analogue to that solution would be but I don’t believe you will find a DS3 card for an ISR device that supports voice.

So, we have an old MUX that died. We have to either replace the MUX or use something else. Is it possible to use a DS3 SM on an ISR to terminate the DS3? Right now, we have a DS3 that hits a mux and breaks out to 28 PRIs... those PRIs go into a plethora of VWIC interfaces on a SIP router. Would it be possible to get another module for this router that lets us plug the coax in and skip all of this VWIC/MUX business? Thanks, Nick
