Does isdn4linux support channel bundling?
The current version of isdn4linux support 2 methods of channel bundling: • MPPP (based on sync PPP) • Raw bundling (configured by so-called slave channels) Both variants have their own advantages and disadvantages. See section 2channel. Bonding (16bit channel) is not supported, since it can not work reliably when the dialup connections have deviating latency. Warning: Channel bundling saves time, but not telephone charges. It is useful only if you really need the extra bandwidth.
