Configuring the System for SpectraLink NetLink TelephonesConfiguring the System for SpectraLink NetLink Telephones
SpectraLink NetLink Telephones require an extra Operating System configuration step to optimize
integration with Operating System. That configuration step is to enable long preambles in the Operating
System:
• Using the Command Line Interface
• Using the Web User Interface
• Using the Cisco Wireless Control System
Using the Command Line InterfaceUsing the Command Line Interface
Use this procedure to optimize the Operating System to communicate with SpectraLink NetLink
Telephones using a long preamble.
• Log into the command line interface as described in Logging Into the CLI.
• Use the show 802.11b command to view the following parameter:
Short Preamble mandatory....................... Enabled
which shows the Operating System default, Short Preamble Enabled; if this is the case,
continue with this procedure.
If this parameter indicates Short Preamble Disabled, this Cisco Wireless LAN Controller is
already optimized for SpectraLink NetLink Telephones; if desired, continue with the Product
Guide.
• Disable the 802.11b/g network using the config 802.11b disable network command.
