Checking V.24 Access
If you have installed a modem dial-up or a computer-to-computer comms cable
connection on your PC, but at Dial-Up or Connect, there is no connection, check
that:
• The Maintenance Cable is undamaged and correctly plugged.
• If you are using a computer-to-computer comms cable connection to
direct-connect your Windows XP PC to 9500 MXC, reboot the terminal (power
off, pause, power on). Remember to always disconnect your CT PC before
removing the V24 cable; click on the networking icon, lower right on your
screen, and select Disconnect. If not done, the V.24 NMS port on the NCC card
can think it is still connected and not answer further connection attempts until
rebooted. If rebooting is not an option because of disruption to service, try the
following:
• With the V.24 cable installed, click on the 9500 MXC shortcut to open the
Connect 9500 MXC window, select Properties > Networking > Internet
protocol (TCP/IP) > Properties > Advanced, and deselect (untick) the
tickbox for ‘Use default gateway on remote connection’, followed by OK,
OK, OK, Connect.
If you have established connection to 9500 MXC (the CT Start Up window is
displayed), but at Connect access is denied, check that the IP address for the
V.24 maintenance Port is correct.
• The V.24 maintenance port uses a default IP address to secure access to the
locally connected 9500 MXC Node or Terminal. IF V.24 access is denied
because of a changed address, use the following procedure to check and enter
the new address in the CT start-up window.
Should there be a change to the default V.24 IP address, it will most likely be as a
result of a change made in the Networking screen under IP Addressing >
Advanced. For more information, refer to Chapter 10.
The default V.24 IP address is 192.168.255.225
