router for SONET/SDH

[christian.pinedo]

Hello,

Until now I have always worked with LAN switching and small ISR routers, but now we need a router with a SDH STM-1 interface that in a future will probably have to be increased to various STM-1 interfaces or to a STM-4, STM-16, ... I also will need at least two Ethernet RJ-45 slots.

I would appreciate some information about which router serie is the most suitable since I don't know nothing about those series.

Thanks in advance,

Christian

Thanks but I'm more interested in the routers series that will fulfil better for my needs... what do you think??

If there is any way you can avoid using a sonet interface, you should try.

Sonet interfaces are pretty pricey.

You will have a bit more flexiblity in your hardware choices.

If this is a carrier service they "may" provide an ethernet handoff.

To give us a transport service between two locations they only give us this option, a SDH/STM-1 interface. I would also prefer not to use it because I'm a bit lost :-)

Well, that settles that!

Latchum gave you a solid lead as far as linecards/devices.

In the end, Sonet is just another link layer protocol, with some nice features (protection switching if its provisioned)

And what about the router models that best suit? I suppose that there isn't SDH/SONET interfaces for ISR GR2...

Joseph beat me to it.

My 'personal" choice would be the ASR.

The "smallest" routers that would support a STM-16 would be the 7304 and the ASR 1000 series.
