onetoone
onetoone, none, alltoone, unstructured, configured
With Fractional mode turned on, it is possible to map
B Channels to specific WAN ports. In this way a point to
point link (rather than an ISDN link) is created. More
than one channel can be mapped to a WAN port.
The default value here of onetoone means that one B
channel is mapped to one WAN port. To increase the
amount of information passed through WAN ports, you
may want to increase the number of channels per port.
The values available for this option are as follows:
• OneToOne: Each B channel is mapped to a single
WAN device, for example, 1 - WAN01, 2 -
WAN02.
• None: This disables the mapping.
• AllToOne: All available channels are mapped to a
single WAN device giving 2 MBits worth of
bandwidth.
• Unstructured: The e1 framing channel is also used
for data, giving 2 MBit leased line. This option can
only be used on Nautica to Nautica connections.
