Hi Paolo,

Thanks for u r reply.

Please clarify that the Central location is having E1 PRI,but other location is having 3 no.s of BRI ckts, how to group these BRI's so that i can get total BW of 384Kbps which is the minimum bandwidth for Video traffic.

Don't you have broadband or something on these locations ? That is a better option than ISDN for IP connectivity. Mon, 04/27/2009 - 04:37

No broadband connectivity is available in this location.

Hi Paolo,

Currently we are having 1760 Routers.

Can these routers are used for this setup(connecting E1 PRI on one router and 3 BRI on other)?
