[cisco-voip] ISR G2 PVDM3 DSPs on backplane

[Jason Aarons (US)]

A TAC engineer at Cisco Live confirmed you can't have multiple voice PRIs from separate telcos come into a G2 with different clocks. For example you have a AT&T PRI, a Verizon PRI, a Century Link PRI, a Alltell PRI, a Paetec PRI all in the same router. You can't clock the backplane to  more than one source!  You'll get slips, etc audio will sound bad, faxes/modems will fail.  Fix is separate routers.  He said he thought a 2800 with DSPs on a NM-HDV module would work though.  My exact question was can you carve up the backplane PVDM3 clocking for separate PRIs somehow.
