Configuring inbound calls
When a MAX unit receives a call on a WAN line, it performs CLID or DNIS authentication (if
available and configured), and answers the call. The unit then uses information in the call, and
information about the channel on which the call arrives, to determine which slot should receive
the call and to authenticate the call, build a session, and pass 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, a caller wants to dial into a V.110 card installed on a
MAX. The telephone number of the MAX is 510-555-1212. The subaddress of the V.110 card
is 4. To reach the V.110 card, the user must enter 5105551212,4 which is the telephone number
of the MAX with the subaddress. (The subaddress (4) follows the dialed number and is
separated by a comma).

Open the System > Sys Config profile.
Set the Sub-Adr Routing parameter to Routing to specify that the called-party number
may or may not have a subaddress.
Set the Serial parameter to specify the ISDN subaddress associated with the MAX unit's
ports.
Set the LAN parameter to specify the ISDN address associated with the MAX unit's
bridge/router or terminal server.
Set the DM parameter to specify the subaddress associate with the MAX unit's digital
modems.
Set the V.110 parameter to specify the subaddress associated with the MAX unit's V.110
modems.
