8540 msr

Can the 8540 msr switches atm modules talk to cabletron(ssr2000)atm modules and how?

What is the basic difference between port adapter and interface module?

In c85ege-2x-64k what is 64k?

We are installing 4 port oc12/stm4 interface module along with c85ege-2x-64k.Do we need arm?

What is the difference betwwen arm1 and arm2?

Re: 8540 msr

As long as SSR2000 ATM modules comply to ATM specs, We shouldn't have any problem talking to it.

An Interface module is a full length module which slides into a slot in an 8500. A Port adapter on the other hand is a half length module, which needs a host module called Carrier module to fit into the 8500. One Carrier module can hold two Port adapter modules.

64k at the end of c85ege-2x-64k represents the number of route entries the module can hold.

Yes, you need an ARM

The differences between the ARM1 and ARM2 can be found in following URL
