router search

Hi,

I need a T1 router with these specifications:

Maximum size - 16" x 9" x 4"

-40C to 70C operating temperature

T1 interface with CSU/DSU

Interoperability with Cisco IP multicasting.

AC or DC power

Qty. 5

network is T1 point-to-point

The Cisco1941 comes closest but it is too big. I'm hoping that someone in the forums know of another router that would fit the specs.

Thanks,

David

David,

May be a 1921 will suit

Hi David,

a T1 on a smaller router than a 1941 is quite a brave choice.. maybe to review your design and the computational needs/requirements before buying something smaller...

The size of the 19XX is too big for my enclosure and the temp spec doesn't work. The application is low-bandwidth radar data so the router itself should work just fine.

The current network is 56DDS...telco is phasing that out and pushing everyone to T1 hence the change.

Thanks,

David

Hi David,

it is not only a computational issue. Check here for what you realy need and you will see that the 1921 is a quite "brave" choice...

There could be many needs/requirements that a simple 1941 could provide and there is no so much difference in the price..

Enjoy your 56DDS anyway!!!

No, that's not correct. The 2501 of 20 years ago was handling 2 T1s with no features just fine. All Cisco routers of today have no issue in handling multiple T1 with features enabled. Remember that T1 is a very slow interface.

Hi Paolo,

you could be right unless considering that the 2500 series was facing very different needs and requirements. A 2500 series for example could even host only serial and no ethernet cards but this is not what the internetworks today require for. My suggestion to David is from a scalability viewpoint and from a design perspective. The 1921 is nearly a solid config and doesn't leave many choices. Since the difference in price with the 1941 is very small, it makes much more sense to get a 1941 than a 1921.

The flexibility is what let survive historical routers like the 2600s or the 7200s. You can even notice the diference between the 2801 and the 2901.... It is the same reason that pushed me to suggest the 1941.

Nevertheless, i am sure David can decide the bes for his enterprise

Re: router search

Actually, all 2500 series router had one or two LAN interface.

Going back to the present, one can be reassured even a small router like 1905 will handle one or more T1s without any problem.

Perhaps an 819?

But it's a 3G router, not T1. To be true, not even the 1905 I've suggested above has native T1.
