Bonded T1 Router upgrade options.

[ddgalura8o8]

We currently have a Cisco 1721 Router on a T1, we are planning to upgrade to a Bonded T1 in the coming weeks. Can someone recommend which Router 1800 or 2600 series to upgrade to. We have apx.30-40 PCs onsite connected with high streaming video/data being our concerns.

I am thinking of the 2610XM. Would it require 2 WIC-1DSU-T1 cards (possibly swap it from the 1721) for the Bonded line. This is my first time setting up a Bonded T1, and was looking if it would require 2 lines into the router for the Bonded T1 on our end. Thanks.

Actually, you could continue to use the 1721 and just ADD an additional T1 WIC interface. From there you could just bond the T1s internally.

If you want to upgrade the router anyway, I would recommend the 1841.

As for the AGGR router side, yes you would need to bring up the second T1 on a seperate interface (unless you have them channelized into a DS3 or the like) and bond them on that side too.

I would recommend getting a 1841. Its very versatile can take upto two wic slots and two fast E intefaces. YOu can use 2 WIC-1DSU-T1-v2 cards (V1 cards wont work) on these routers and use PPP multilink to bond them. Check the spec sheet for 1841.

Thanks for the replies. Our T1 rep had just recommended a 2600 series because of the faster cpu to handle the T1 bond. The WIC card we have is a v2 and it is compatible with the routers mentioned. I have been looking at both the 1800 series and the 2600xm series. And weighing in either towards the 1841 or 2610xm. Would the 2610xm be faster? I know the 1841 is the upgrade from the older 1721 and is 5 times faster, but the revised 2600xm series how does that compare to the 1841.

Look at 1841s Miercom report findings.

The only advantage you get with a 2610XM is that youhave a NM slot available for future expansion. 1841 doesnt have a NM slot.

According to this document,

http://www.cisco.com/warp/public/765/tools/quickreference/routerperformance.pdf

PPS for 1841 is 75000, versus 2610XM is only 20000. (Note that these performance stats are determined using 64 byte size packets).
