I need to connect a voip network with a telephonic switch system using an E1 connection. I was trying to do this using a MC3810, but I noticed that it doesn't support r2-digital signaling and I couldn't make it work using digital E&M too. So, I'm thinking about to buy other router to do this and I need to know if I'm choosing the right router. Does the 2620xm /2621xm support r2-digital in E1? What would I need to connect this, just the router, a Vwic-2mft-e1 and a PVDM2-64? Do I need a NM-HDV2? Would the 2800 series be a better choice in this case?
Thanks for any help,
