Usage | |
Always use 1 B Channel |
Only 1 B Channel is used for Internet Access. The 2nd B Channel is never used for Internet Access, but is available for Dial-in Access (if enabled and configured). |
Dynamically use 2 B Channels |
For Internet Access, 1 or 2 channels are used, depending on the volume of traffic. If Dial-in Access is enabled, then the 2nd B Channel will be dropped if required to allow connection of an incoming call. |
Always use 2 B Channels |
If an Internet connection is required, both 2 "B" channels are always used. Dial-in, if enabled, is only possible if no Internet connection exists (the Level One ISDN Router is idle). |
Outgoing Call ID | |
MSN | If provided, enter the MSN (Multiple Subscriber Numbering) which receivers of your calls will see (using caller ID). The phone company will bill this number. |
SAD | If provided, enter the SAD (SubAddress). The SAD acts like an extension number to your main ISDN number. You can dial-up from this number instead of the main number. |
Incoming Call ID | |
MSN | If provided, enter the MSN (Multiple Subscriber Numbering) which callers should use to connect to this device. |
