Table 3-2. Mode Types for BRI Operation
Mode Meaning
2b+d Specifies that this is an ISDN switched line that provides two B channels,
and call setup occurs between the router and an ISDN switch.
1b+d Specifies that this is an ISDN switched line that provides only one B
channel, and call setup occurs between the router and an ISDN switch.
Use this option when you do not need to use two B channels.
floating-b Only for AN, ANH, and ARN routers. Specifies that although this is an
ISDN switched line providing two B channels, the software makes the
necessary adjustments if only one channel is in use. Use this option if you
can purchase only 2B + D service, but only want to use one B channel, or
your application requires two synchronous ports and only one B channel.
leased-64k Specifies that this line provides one B channel that is always available. No
call setup occurs with an ISDN switch. Instead, the switch has a defined
point-to-point connection between two ISDN end points (Germany and
Japan only).
leased-2x64k Specifies that this line provides two B channels that are always available.
No call setup occurs with an ISDN switch. Instead, the switch has a
defined point-to-point connection between two ISDN end points
(Germany and Japan only).
leased-128k Specifies that this line provides one B channel that is always available.
(The extra bandwidth of the 128 Kb/s channel is equivalent to having two
B channels of 64 Kb/s.) No call setup occurs with an ISDN switch.
Instead, the switch has a defined point-to-point connection between two
ISDN end points (Germany and Japan only).
