I currently have the following set up : a cisco 7513 handles all frame relay traffic ( about 30 384k ckts) and a cisco 3640 with 4 pri's(96 channels) that handles all the isdn router dial in traffic ( as a side note an ascend max with 2 pri's handles incoming analog and isdn traffic from pc dial in) i am needing to upgrade the number of pri's( add another pri- 24 channels) that the 3640 can handle but wonder if this might be a good time to move all of the traffic over to the 7513 . it is working fine like it is but i know the 7513 is certainly capable of handling all of this traffic and more. I am hoping someone can share some pro's and con's to consider before making a final decision. thank you for any and all replies, Jerry D. ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
