#_ Unless you are ready to spend in 6 digit figure per month, IMHO I think it
#_ is better to set-up your own dial-up network. That means you need 20
#_ phoneline for the 10 branches, and you will need a multi-port serial card
#_ (is this the official name?) If my memory works correctly, I think the 8
#_ port card is just around 25,000.00 you can have 2 of these on your HQ in a
#_ Linux Server and have 10 Modems + 10 Phonelines waiting for each of the 10
#_ branch to dial-in. For internet access the HQ server can have additional
#_ modem to ISP or even a cable internet connection.
#_ with this setup you will only be spending around 30,000.00 per month (for
#_ the 20 phonelines + dial-up account on ISP) against at least 100,000.00 per
#_ month networking with VPN.
You mignt not need to spend that much for a multiport card. If you are using
Kernel 2.4 or kernel 2.2.18 you can get a couple of 4-serial-port usb
device. Look in /usr/src/linux/Documentation/usb/usb-serial.txt for more
info. One end is plugged to a usb port, the other end is a 4-serial-port
hub.
From /usr/src/linux/Documentation/usb/usb-serial.txt:
ConnectTech WhiteHEAT 4 port converter
ConnectTech has been very forthcoming with information about their device,
including providing a unit to test with. This driver will end up being
fully supported.
Current status:
The device's firmware is downloaded on connection, the new firmware runs
properly and all four ports are successfully recognized and connected.
Data can be sent and received through the device on all ports. Hardware
flow control needs to be implemented.
Digi AccelePort Driver
This driver supports the Digi AccelePort USB 2 and 4 devices, 2 port (plus
a parallel port) and 4 port USB serial converters. The driver does NOT
yet support the Digi AccelePort USB 8.
This driver works under SMP with the usb-uhci driver. It does not work
under SMP with the uhci driver.
The driver is generally working, though we still have a few more ioctls to
implement and final testing and debugging to do. The paralled port on the
USB 2 is supported as a serial to parallel converter; in other words, it
appears as another USB serial port on Linux, even though physically it is
really a parallel port. The Digi Acceleport USB 8 is not yet supported.
Please contact Peter Berger ([EMAIL PROTECTED]) or Al Borchers
([EMAIL PROTECTED]) for questions or problems with this driver.
HTH.
