Device to select modem on multiple lines?

I am looking for a device that would enable us to dial into a site (via MODEM) using one phone line, and direct the MODEM call to 1 of 6 systems (each with their own MODEM).  This device must allow Control or routing from MODEM software such as PCAnywhere.

Basically, we have six independent computers with MODEMs but only one telephone line (cannot install anymore lines) and we need to connect to one system at any given time.

Ideally, this device should cost less than $400.00.

Suggestions?
Thank you

Back in the 1970s, we had a Gandalf PACX with serial-lines
to several (6, in your case) computers, on one "side" of the PACX, and multiple modems on the other "side" of the PACX.

Users would use their modem to connect to the PACX,
and then enter '1' to connect to the first computer,
or '2' to connect to the second computer, or ...
as defined by the system-programmer who configured the PACX.


At the time, it was way more than $400.  :-)

If all of the other systems are located in the same location - you would be better off to install a network linking all the other PCs together - then cal into the primary PC via modem (using something like PCAnyWhere) then set up a second session using  netbuei  or TCPIP  to get to the other PC's.

your total cost will be under $400 depending on whether or not you run your own cables.

You will need

7 Nics  - About $15-20 ea
8 Port 10bt Hub  - under $100
box of cable  - About $80-100

If your running a 10Bt network - you can just use Jack ends (14 of them at Under $1.00 ea  and a Crimp Tool - )About $25-30

If security is a problem then don't share any folders  (only Printers)

DTHConsulting: I should have mentioned that these systems are already networked and using PC Anywhere for remote monitoring.  To rely on one MODEM could be a problem if that primary system goes down.  We really need independent access to each system.

This is really strange. I replied to Otta and now that message is gone???  Basically, I stated that I may have found a suitable product (can't remember the name though I did write it down in Otta's reply).

I'll leave this question open for now... I'm still open to suggestions.

Thank you all!

If you are already retworked and each PC has a modem just set the answer on x rings 2 rings apart on each of the PCs. Your main PC answers on 1 ring  - Second on the 3rd ring, 3rd ont he 5th Ring  etc

If the first system goes down - the second will pick it up on the 3rd ring  and so on

PCAnywhere can be set to monitor 2 devices in host mode. Modem and TCPIP  or Modem and NETBUEI.

This should solve your problem.

An Experts Exchange "moderator" is closing my account

I will be doing that, in a few moments,
