Feature Description and Benefits
• T1 and E1 PRI QSIG
• E1 MelCAS
• E1 R2 CAS
• T1 and E1 Transparent CCS (with Multi-D channel)
• Country-specific signaling
Voice Features
• Conferencing/Transcoding
1
: Supports up to 50 eight-party G.711 ad-hoc conferencing sessions, or up to 32
eight-party multi-codec (G.711/G.729) ad-hoc conferencing sessions. A maximum of 128 transcoding sessions
between G.729a and G.711 codecs, and 96 transcoding sessions between G.729 and G.711 codecs.
• Echo cancellation: Industry-leading G.168-compliant software echo cancellation provides echo cancellation on
tail circuits up to 64 Mbps.
• 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. Includes "Trader Turret" PLAR.
• Local/Advanced Voice Busy-Out (LVBO/AVBO): Automatically busies out any desired voice trunk line to a
PBX or PSTN when a direct WAN or LAN connection to the router or any part of the network to the destination
port is down.
• Caller ID support: Per-port configurable caller ID (with per call un-blocking) over analog FXS, FXO and DID
interfaces.
• Hunt groups across cards: Calls can be forwarded automatically to the first available line.
• Integrated add/drop multiplexer (drop and insert): Performs add/drop multiplexing for voice within a multi-
port voice Network Module. Eliminates the requirement, maintenance, support, and expense of using an external
add/drop multiplexer.
• Channel bank: Supports the conversion of analog voice ports into digital voice traffic using DS-0 channels on a
T1 or E1 interface.
• Dial plan mapping: Simplifies configuration and management through automatic mapping of dialed phone
numbers to IP addresses.
• Interactive Voice Response Support (IVR): Provides automated-attendant, voice-mail support, and call
routing based on desired service.
• Hoot and Holler over IP: Delivers superior quality Hoot and Holler multicast voice services and multicast
conferencing over the WAN using existing end-points.
Voice Port Interfaces
• Supports FXS, FXO (includes CAMA), DID, E/M, BRI (S/T), T1, E1, and J1 interfaces.
Voice Port-Specific
Features
• FXS and FXO: Provide battery polarity reversal detection and initiation for disconnect supervision and far-end
answer supervision.
• ISDN BRI network side and phantom power: The VIC2-2BRI-NT/TE provides the ability to connect a
PBX/PABX configured as user side directly to the router. Also provides phantom power to accommodate
equipment that requires it.
• Analog CAMA trunk connection: The VIC2-2FXO and VIC2-4FXO provide the ability to connect to analog
CAMA trunks which provide dedicated E-911 services. Each VIC port can be individually configured as an FXO
or a CAMA port via Cisco IOS Software.
