System Features
Affected by the Dial
Plan Configuration
The dial plan configuration affects several system features:
■
Keyset Mode Operation Using the Dial Plan
■
Hybrid Mode Operation Using the Dial Plan
■
Off-Site Notification
Keyset Mode Operation Using the Dial Plan
If you map any telephone buttons that have LEDs to specific Analog Line
Card ports, you enable Keyset mode in the NBX system. Instead of dialing
a single digit (typically 8, 9, or 0) before placing an outside call, the user
presses a button to select an available Analog Line Card port. The user
defines the routing (that is, the selection of a destination device) by
pressing the button to select the Analog Line Card port; however the NBX
system controls the call using the dial plan.
You cannot map a digital line extension in Keyset mode.
The NBX system applies any Class of Service restrictions that are
associated with the user's telephone to determine whether to make a
call. The system also uses any pretranslator that a device uses and
performs any required digit manipulation operations before it actually
transmits the digits on the Analog Line Card or Digital Line Card port.
Hybrid Mode Operation Using the Dial Plan
If you map telephone buttons for some telephones but not others, you
enable Hybrid mode (a mixture of standard and Keyset behaviors). The
system provides a system-wide External Prefix setting, which allows the
administrator to establish a prefix.
Off-Site Notification
The NBX system uses off-site notification to notify users when new voice
mail messages arrive. You can define notification devices and assign them
in the Internal dial plan as well as through the NBX NetSet utility.
