TDM link between two voice router

i have 1 AS5350 with 4 E1 ports and 2811 with VWIC-MFT module. I want to connect two routers through E1 ports using PRI/CAS signling in order to transfer voice in POTS. Anyone could help me, what type of physical connection should use and the configurations of the two routers.

Thanks in advance.

Re: TDM link between two voice router

Forget about CAS that is complicated and doesn't have the good features. Configure one router as network-side PRI, as described at:

http://cisco.com/en/US/docs/routers/access/as5350/software/feature/guide/puldtpri.html

Also remember to place clock source internal under controller E1, for one router only.

Hope this helps, please rate post if it does!

Just a crossed cable (RJ-48c crossing, NOT ethernet crossing). Note the 2811 must have PVDM2 installed for this to work.
