Configuring the serial WAN port
A MAX unit has a built-in V.35 serial WAN DB-44 port. A serial WAN port provides a
V.35/RS-449 WAN interface that typically connects to a Frame Relay switch. To co nfig ure the
serial WAN port, open the Serial WAN > Mod Config profile and set the following parameters:
For detailed information about each parameter, see the MAX Reference.

Configuring a serial WAN connection

To configure the serial WAN interface to connect to a Frame Relay switch that uses static data
flow, proceed as follows:
1Open a Net/T1 > Line Config > Line Config profile > Line N subprofile.
2Make sure at least one Ch N Prt/Grp parameter has been set to specify a nailed group.
3Exit the profile and, at the exit prompt, select the exit and accept option.
4If the profile you have configured is not the active profile, activate it as described in
“Activating a profile” on page 2-7.
5Open Serial WAN > Mod Config.
6Assign a module name and a nailed group number.
7Set the Activation parameter to Static to specify that the MAX unit will not use flow
control signals, because the DCE is always connected.
8Exit the profile and, at the exit prompt, select the exit and accept option.
9Configure a Frame Relay profile and specify the Nailed Grp number assigned to this port.
For more information about Frame Relay, see Chapter5, “Configuring Frame Relay.”

Parameter Specifies
Module Name A descriptive name for the interface. (This parameter is optional.
Functionality is not affected if you do not enter a value.)
Nailed Grp The group number that supports the serial WAN connection. Because a
serial WAN connection is nailed, you must assign a gr oup number to each
nailed channel. More than one nailed channel can use the same group
number.
Activation The signal or signals the system uses to indicate that the Data
Circuit-terminating Equipment (DCE) is ready to connect.
Ext. Clock * 1K Maximum bandwidth that the un it uses for the nailed portion of a
Nailed/MP+ call. The externally generated clocking speed you specify is
multiplied by 1024 to calculate the bandwidth.
