Re: do you think isdn and frame-relay expire?


I am not clear whether your question is about content of Cisco cirtification books and tests or is about current networking practices. If it is about Cisco certification books and tests then I am not in position to be able to address that. If it is about current networking practice then I find that ISDN and Frame Relay are still very much present and active in the production networks that I deal with at customer sites.



Re: do you think isdn and frame-relay expire?

Hi Reza,

if you are talking about new CCNP curriculum, then ISDN and Frame relay technologies are no longer included there. ISDN and Frame relay were included in the Remote access paper of CCNP old curriculum but now that paper is replaced by Secure Converged Wide Area Networks paper which includes MPLS, IPSec VPNs and other technologies.

But as Rick said in earlier post that ISDN and frame relay are still very much in use.

hope it helps ... rate if it does ....
