I think it's somewhat common. It's been around for a while very common. particularly in hub and spoke situations, where the host site needs to aggregate a lot of bandwidth from a lot of remotes. way cool also is that if your telco supports it, you can do DSL to ATM also, giving quite a bit of flexibility. I have customers who are doing FRATM ( frame relay in the remote sites, and ATM at the host ) and RLAN ( DSL at the remote sites and ATM at the host site ) I don't have any customers shooting the works myself, but a couple of my co-workers have done some pretty exciting designs mixing ATM, frame, and DSL at remote sites and high cap ATM at the host. neet! > > ___ > > Priscilla Oppenheimer > www.troubleshootingnetworks.com > www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=65013&t=64923 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Basic Frame Relay question [7:64923]
They could. In fact, its quite likely. The link from your CPE goes into a port on one of their WAN switches. from there it goes over a trunk utilizing either Fast Packet (FP) or ATM to another WAN switch. There may be a number of WAN switches between your CPE and the destination CPE. You can get more detail from the documentation on Cisco's WAN switches.

The configs of the frame CPE and the ATM CPE wuld be the same as if you had frame/ATM respectively on the other side. The only caveat is you will most likely need to use IETF encapsulation on the frame since you will most likely not be terminating on a Cisco for the internetworking component.

Re: Basic Frame Relay question [7:64923]
indeed, much like what happens with frame relay into x25, which gets encapsulated directely but in the case of FR and ATM there is some mapping to be done, like the DE field mapped to the CLP, and translation etc...; ""John Hutchison"" a icrit dans le message de news: [EMAIL PROTECTED] > Frame Relay connections CAN be fed into an ATM circuit at your provider's > end.

Basic Frame Relay question [7:64923]
I am looking at frame relay. As I understand it, the frame relay connection goes from the CPE to the service provider CO. My question is, does the destination device on the other side of the CO also need to run frame relay? Could they perhaps run ATM? My CPE CODest.
