Maximum E1 Cards supported on 2811

Hello All,

Wanted to confirm maximum E1 ports supported on 2811 without any performance degradation.

2811 has 4 HWIC slots, i need 8 E1 ports to be connected to different sites.if i populate all 4 slots with VWIC2-2MFT-G703 which makes 8 E1 ports, Any performance issues??

Thanks in advance.

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

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.
