[cisco-voip] Quick Question regarding VWIC2-2MFT-G703 and E1 Cards

[Syed Khalid Ali]

Dear all,

I was looking at the data sheet fro VWIC2-2MFT-G703 and E1 cards and
it says it support independent clock sources but it will not allow
Voice applications.

I have a scenario, with 2-port G703/E1 card, of port is connected to
PBX and other with service provide network. the ultimate goal is to
carry voice traffic to other PBX that will be connected over the WAN
using G703 or E1.

I really confused since the PBX side will the the network side
(typically) and off course the telco will also be provided the clock
to the controller. and in case of independent clock sources voice is
not supported.

So should I order two different cards, one for data and one PBX
interconnectivity???
