Configuring call routing
This section describes how to configure incoming and outgoing call routing on the MAX unit.
If you have a mixture of incoming calls, such as modem and digital, this section answers your
questions about routing those calls to the proper modules on the unit. This section also includes
a state diagram illustrating incoming call routing. The last part of the section describes how the
unit handles outbound calls.
Routing inbound calls
When the MAX unit receives a call on a WAN line, it performs CLID or DNIS authentication
(if available and configured), answers the call, and determines which slot should receive the
call. It then authenticates the call, builds a session, and passes the data stream to the
appropriate module or host. If a call is routed to the Ethernet port, the bridge/router software
forwards it to a host or hosts according to packet addresses.
Setting up ISDN subaddressing
When you use ISDN subaddressing in routing mode, incoming calls include a subaddress
number as part of the telephone number. When routing a call, the MAX unit first checks for the
ISDN subaddress. If the unit finds one, it uses the subaddress to route the call. If not, it goes on
to the next comparison.

Example of ISDN subaddressing configuration
With the configuration in this example, the caller would dial 510-555-1212,3 to reach the
digital modems. The subaddress (3) follows the dialed number and is separated from it by a
comma.
