> A wide variety of topics have been brought up lately. What are the lists users thoughts of other remote access products compared to 3com- Total Control? It seems the 3com is widely used products among the ISP forum. Any comments are appreciated.
Heres the ones ive personally used
Cisco AS5248
The good - excellent support
excellent feature set
'no one ever got fired for buying cisco'
The bad - IOS was never really designed for handling dialups and it shows
Severely underpowered CPU (68030)
'merely adequate' modem DSP code
Lucent PM3
The good - good feature set
good tech support
The bad - Somewhat underpowered cpu
'fair to good' modem DSP code
ComOS can be flaky (spontaneous reboots etc)
3com Hiper
The good - good feature set
blazingly fast CPU and architecture (overengineered? :)
excellent modem code
The bad - terrible tech support
Ascend Max
The good - good to great modem code
good feature set, minor annoyances on some features (eg DOVBS)
The bad - Somewhat underpowered cpu

Line coding errors?
Check out the new updates to my "Line Coding Errors" page at
http://808hi.com/56k/coding.htm
Line coding errors may be much bigger issue than some think - can also occur in telco/clec facilities between subscriber and your switch - something you have little control over!
CT1 = beginning of recipe for 56k trouble
get PRI if at all possible.

It wasn't my intention to imply that CT1s will perform worse when there are line coding mismatches somewhere in the chain.... However, I didn't explain why I said that CT1 is the first ingredient in a recipe for 56k trouble: and, the answer is: RBS. CT1 means you've got an RBS link between your equipment and the telco. If there is any other RBS link in the call path to the customer (ie, SLC, remote office trunks, etc.) decent 56k connections may be impossible unless the RBS links align - a 1-in-6 chance. 56k client modems are supposed to be handle multiple RBS links, but they often do not.

We are a new ISP and all our equipment (routers, USR TC) were installed by our TELCO provider for warranty purposes. However, I would like to learn as much a possible about our equipment, specifically our TC chassis. I don't know what kind of cards we have, what revisions, etc. This is all information I would like to know. Where can I get familiar with the equipment I have?

I was just now able to get the TCM software from usr's site. I wasn't able to get my contract number!! Anyway, I have been told that there is an add-on that will let me look at each DSP card and tell what modems are being used and who is the user. Anyone know what the name of this add-on is? Is there any other cool add-ons I can get? Also, can anyone tell me what SNMP traps to enable in TCM so that I can use MRTG to graph modem usage?
Thanks for all your help,

Thanks for the help guys but I still need some more. I'm running all HiperDSP cards and can run the command line "perl hiperdsp.pl public@xxx.xxx.xxx.xxx" and I get a list of two numbers, which is the number of users online and the total number of modems. That's great but how do I incorporate this into MRTG? When I make a mrtg.cfg file and use the OID that is in the hiperdsp.pl file, 1.3.6.1.4.1.429.1.27.2.1.26, and then run mrtg, i get an SNMP error: no response received. How can I get this to work so that I can graph out modem usage?? I have included the mrtg.cfg file:
I'm trying to assign static IPs to some ISDN users. I'm using HiperDSPs with RadiusNT authentication. I have tried letting the end user just set the IP on their computer but that doesn't work. I only have one IP pool set up and this includes 46 IPs of my class C. Do I need to make another pool and if so, how? I tried to add one and put in the initial address but I keep getting an error that it is not a valid address. I'm using the syntax xxx.xxx.xxx.xxx. Any help??
