hmmmm... Seems like a simple set of rules to assume. But, if you were in a hurt, I'd bet you could get away with the 23 per DSP card and a hand full of extra numbers for a buffer. The science would tell you that 23 per card would make it fine. But, buffers are buffers for a reason. If you have the IPs available, Paul seems to have good advice. I actually put 1 IP for each access circuit. Then, I ad a few for a safty net. I have actually run with around 20 too few before, and had only minor problems (when I maxed out - DUH!). So, it's an IP per user online ratio - that simple. But, I am only saying what has already been said a few times before. Unless someone knows a bit of information about the network capacity of these cards that would lead us to another conclusion - I am running on common sense. If there is a bug to defer through an overage in IPs, please post this ASAP. I do not want to be left out in the cold on this simple an issue. I can order IPs like anyone - and would be happy to just- ify a few hundred more than I need. (or would need if equipment were perfect).

Subject: Re: (usr-tc) Recommended ip pool size. I would use 24 IP's per DSP. Since IP's are handed out on least used priority you would not have to worry about a person calling up, dropping and another totally different users then hooking up with the same IP and not getting anytwere because the previous IP user started a 25Mb DL. Add that 24th IP address in there. Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Mon, 20 Dec 1999, Tatai SV Krishnan wrote:
Depends upon your maximum number of ports. So in your case you need an ip pool of 23 address for each pri card.

We have a HiperARC chassis with PRI service. Can anyone give me a suggestion on what the recommended ip pool size would be for one PRI span (23 modems)? I haven't been able to find this info anywhere in any documentation.
Thanks in advance.
