Configuring WAN Access
Configuring T1 lines
channel is used only if the primary line goes down or if it receives a signal commanding a
change to the other D channel.
Note: On a MAX 6000 unit, both lines must be connected to the same slot. Also note that if
you were to configure both slots for NFAS signaling, you would have to assign different ID
numbers to the lines in the second slot.
To configure two T1 lines for NFAS, proceed as follows:
1 Open a Net/T1 > Line Config > Line Config profile and set both lines to Trunk:
Net/T1
Line Config
Line Config profile
Name=
1st Line=Trunk
2nd Line=Trunk
2 Open the Line 1 subprofile and set the signaling mode to NFAS:
Line 1...
Sig Mode=ISDN_NFAS
3 Keep the default NFAS ID.
NFAS ID num=1
4 Configure a channel as the primary NFAS D channel. For example:
Ch 24=NFAS-Prime
5 Close the Line 1 subprofile.
6 Open the Line 2 subprofile and set the signaling mode to NFAS:
Line 2...
Sig Mode=ISDN_NFAS
7 Keep the default NFAS ID:
NFAS ID num=2
8 Configure channel 24 as the secondary NFAS D channel:
Ch 24=NFAS-Second
9 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in
“Activating a profile” on page 2-7.
Example of NFAS configuration

parameters are shown.)
