CAPABILITIES

The Indy transfers circuit switched data on the B channels.

A point to point (PPP) daemon runs in the background on the Indy and uses ISDN to set up a IP link to the destination machine.

Both B channels can be combined using a round-robin packet sending scheme to maximize throughput. This is sometimes called "inverse multiplexing". It is also similar to "bonding".

PPP can also be configured to bring up one or both B channels as the bandwidth demand increases and bring down the channels when the demand decreases. This is commonly known as "bandwith-on-demand".

PPP utilizes a variety of compression, thus increasing data throughput to beyond 128Kb.

PPP uses PAP to authenticate connections.

For more specialized data transfer applications which do not want to use PPP, an ASI interface is available.

INTEROPERABILITY

The Indy is interoperable with the following:
