How can I tell if I have established a MultiLink call?
Both of the B channel LEDs on the 3C882 ISDN modem’s front panel, B1 and B2, will be illuminated green. Also, you can use terminal emulation software to send the command AT\S. The result is a list of information about the call you just placed and it will indicate whether or not MultiLink PPP is enabled. Note that by default, the 3ComImpact IQ ISDN modem displays the COM port speed of your computer (for example, 115000 bps). You can have both the COM port speed and the network connection speed displayed by sending the command ATW1 to the ISDN modem. Also, to display just the network speed, send the command ATW2 to the ISDN modem. Note that when establishing a MultiLink call, if you changed the default to display the network speed, it will only show a 56 Kbps or 64 Kbps connection, not 112 Kbps or 128 Kbps.
