Hello Hardik,


C2811 is accredited of 120000 pps


ISR 2811 3,000 1.536 120,000 61.44 No


so from the performance point of view it shouldn't be a problem


see file in attachment


the 4 slots can be used as you would like:


>> 4 slots, each slot can support HWIC, WIC, VIC, or VWIC type modules

So it should work


depending on WAN provider prices in your region you may want to consider the use of a single NM E3 subrate instead of paying for 8 E1 links



Hope to help

Giuseppe

Thank you very much Giuseppe.


E3 is not available from ISP.

Hi, you should use instead:


NM-8CE1T1-PRIor 2x HWIC-4T1/E1


Also in most cases the regular VWIC is OK, do not need the G703 version.
