SUMMARY
=======

This article provides background information about dual-channel ISDN
connections to MSN, The Microsoft Network. With dual-channel ISDN,
connection speeds up to 128,000 bps are available.

MORE INFORMATION
================

Dual-channel ISDN uses multilink PPP (MP), which is an extension to the
standard point-to-point protocol (PPP) for using TCP/IP over a dial-up
connection. MP allows for combining both channels of an ISDN line
connection to act as a single large pipe for a PPP connection. MP uses two
channels on an Ascend MAX, one for each B channel of the ISDN line.

If an Ascend MAX has only one channel available, a connection is attempted
to a channel on another MAX. When this happens, most connections fail.
