Configuring Multilink PPP
Multilink PPP is a protocol that provides a method for
combining multiple PPP connections. Multilink PPP combines
the two ISDN B channels, creating a virtual single digital
connection of up to 128 Kbps. Note that the destination you
are dialing must also support Multilink PPP, or you will get a
single B channel connection instead of the dual-channel link.
By default, Multilink PPP is enabled. To enable or disable
Multilink PPP, do the following:
1 Click inside the Multilink check box in the PPP area to
clear it (disable) or check it (enable).
