TW-H6W1IR ISDN Remote Router
Advanced Functions
The Advanced Functions menu contains most of the more complex
configuration settings and is shown below:
Remote Access Configuration
The Remote Access Configuration menu is used to set up the router for
dial-in and dial-out connections over the ISDN line. An ISDN line has
a D channel for establishing connections and two B (Bearer) channels,
which transmit and receive the actual signals, whether voice or data.
The two B channels can support two independent remote connections
or be banded together using Multi-link PPP to implement Bandwidth on
Demand (configured separately in the PPP Configuration menu, the
last item in the Advanced Functions window).
The B-Channels can also carry voice and fax calls, which are routed to
the telephone jacks located on the rear of the router. Please note,
