[cisco-voip] ISR G2 PVDM3 DSPs on backplane

[Bill]

What? I know you could not do different Telco's on the same two port card
but you can't do two telco's in the same router? Is there an official
response to this? Is there a specific defect I can reference with my Cisco
AM?

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.
