Feature Description and Benefits
Voice features
●
Echo Cancellation: Cancels echo on tail circuits up to 32 msec (configurable tail length)
●
Silence suppression, voice activity detection (VAD): Bandwidth is used only when someone is speaking. During
silent periods of a phone call, bandwidth is available for data traffic
●
Comfort Noise Generation: This feature reassures the phone user that the connection is being maintained, even
when no voice packets are being transmitted
●
Private Line Automatic Ring-Down (PLAR): Provides a direct connection to another digital or analog voice port
by lifting a telephone handset on one end
●
Caller ID Support: Per-port configurable caller ID (with per call un-blocking) over analog FXS
●
Dial Plan Mapping: Simplifies configuration and management through automatic mapping of dialed phone
numbers to IP addresses
Voice Port Interfaces Support FXS and BRI (S/T, NT/T).
Voice Port-Specific features
●
FXS: Provides battery polarity reversal detection and initiation for disconnect supervision and far-end answer
supervision
●
ISDN BRI Network Side: The BRI port provides the ability to connect a PBX or PABX configured as user side
directly to the router
●
LED indicators for voice-processing resources and port status
Fax and Modem
●
Fax and Modem Pass-Through: Allows fax and modem traffic to pass through a voice port
●
Fax Relay: Provides a more robust protocol for fax transmission over packet networks. Also supports the T.37
and T.38 fax protocols
High-Performance Flexible
Digital Signal Processor (DSP)
Architecture
●
Flexible DSP Architecture: There is no need to specify codec complexity at configuration. An appropriate codec
is dynamically selected when a call is established, while allocating DSP resources optimally
●
Feature Upgrades: The DSP architecture allows for addition of new features through simple code updates
