RS232 specs limit cable runs to 15 meters (50 feet) at 19200 baud rate, but...the slower the baud rate the further the distance you can run RS232. I personally have a mat computer and SMDR collector 1200 feet from the switch but both are only operating at 300 baud.

One other thing we have been using instead of short haul modems lately when we have transport RS232 over long distance is serial to ethernet converters. Converting to ethernet allows us to use fiber optic cable which has eliminated most all of our lightning damage that our RS232 equipment use to have.

thanks again for that information. I have another, hopefully the last one. Can you swap the pc-00 card between systems if you are trying to trouble shoot a problem? I think you can, but I dont' have a system to test with.

yes you can swap the PC-00 between system, the PIM that you are removing the PC-00 from will go down while you swapping the cards.

Also do NOT forget to change the sw setting of the card to match the new location

What are the problems faced in implementing IP Telephony through Neax 2400 IP PBX? Is it a good option for a bank to go for this against Call Manager soft switch?

There are less problems using the existing switch and moving slowly to IP than there would be switching wholesale to a Cisco solution. The slow move gives the benefits of both worlds being a hybrid solution. One example would be to try pricing the addition of analogue ports to a Cisco solution for such things as your fax machines and modems.

There are many arguments for and against Voip the beauty of moving to voip with the 2400 is that you cancel out all the against arguments as the legacy equipment can be utilised. Another big thing is you don't have to retrain everyone and your existing Dterms can if required be fitted with converters. This will also stave off another problem with voip that few take into account.

When you go pure voip the speed of your data network is restricted to the switch speed of your phones as the phone goes between your computer and the network. This means that when the network takes another jump in speed you will only be able to go with it if you are prepared to not only replace your network equipment but also all your telephone handsets.

The main reason given for moving to voip is the savings in infrastructure but in an existing installation the infrastructure is already there so why not use it?

I could continue but you may already have guessed I don't rate Voip. It is simply a way for IT professionals to build their empire further and an excuse for them to get more Cisco certificates. A Government department here has just gone Cisco at a price I am told of about $500,000 whereas the upgrade to the existing system to allow Voip would have been about $50,000 That same department is now about to install a PABX between the Cisco and the telephone network because it is far cheaper than buying the package that will give them the functionality they had with the old system.
