Configure
To configure ISDN NFAS, complete the following tasks in controller configuration mode:
Take a Channel or Interface Out of Service
You can take a specified channel or an entire PRI interface out of service or put it into one of the other
states that is passed on to the switch.
To do so, complete one of the following tasks in interface configuration mode:
These are the supported state values:
• 0—In service
• 1—Maintenance
• 2—Out of service
Verify
Monitor NFAS groups by entering the show isdn nfas group number command:
AS5350# show isdn nfas group 0
ISDN NFAS GROUP 0x0 ENTRIES:
The primary D is Serial0:23.
The backup D is Serial1:23.
There are 2 total nfas members.
There are 24 total available B channels.
The primary D-channel is DSL 0 in state IN SERVICE.
The backup D-channel is DSL 1 in state STANDBY.
The current active layer 2 DSL is 0.
Command Purpose
AS5350(config-controller)# pri-group
timeslots 1-24 nfas_d primary
nfas_interface number nfas_group number
On one channelized T1 controller, configures the
NFAS primary D channel.
AS5350(config-controller)# pri-group
timeslots 1-24 nfas_d backup nfas_interface
number nfas_group number
On a different channelized T1 controller,
configures the NFAS backup D channel to be used
if the primary D channel fails.
AS5350(config-controller)# pri-group
timeslots 1-24 nfas_d none nfas_interface
number nfas_group number
(Optional) On other channelized T1 controllers,
configures a 24 B channel interface, if desired.
Command Purpose
AS5350(config-controller)# isdn service dsl
number b_channel number state state-value
Takes an individual B channel out of service or
sets it to a different state.
AS5350(config-controller)# isdn service dsl
number b_channel 0 state state-value
Sets the entire PRI interface to the specified state.
