Description and Benefits

Integrates all Cisco IP Communications solutions by providing flexible and reliable connectivity to public or private switched telephone networks around the world.
Provides gateway for Cisco IP phones to PSTN or traditional PBXs and private automatic branch exchanges (PABXs).
Provides gateway to PSTN for traditional PBXs, phones, fax machines, and key communication systems connected to a voice, data, and video infrastructure.

Reduce or eliminate toll charges assessed by long distance and local carriers by transporting voice and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN), or WAN.
Works with existing phones, faxes, PBXs, and key systems.
Connection trunks creates a permanent tie-line replacement structure (digital-to-digital, digital-to-analog, or analog-to-analog capabilities).
Interoperates end-to-end with Cisco IP phones, analog phones, fax machine connections, and PBX or PABX connections to and from other Cisco voice enabled products.

Voice/Fax over IP-VoIP traffic at Layer 3 can travel over any Layer 1 or Layer 2 media, including ISDN, leased lines, serial connections, and Ethernet.
Compressed Real-Time Protocol (cRTP) offers RTP header compression and packet fragmentation techniques that allow toll-quality voice and fax transmissions over any WAN connection.
Call Admission Control and PSTN Fallback uses Service Assurance Agent (SAA) to determine latency, delay and jitter and provide real-time Calculated Planning Impairment Factor (ICPIF) calculations before establishing a call across an IP infrastructure. SAA packets emulate voice packets receiving the same priority as voice throughout the entire network.
Advanced QoS Mechanisms-These configurable Cisco IOS Software features reserve appropriate bandwidth and prioritize voice and fax traffic to help ensure transparent delivery of toll-quality voice and fax. They include Resource Reservation Protocol (RSVP), queuing techniques (such as Low Latency Queuing), IP Precedence, and differentiated services code points (DSCPs).

Supports H.323 V1/V2/V3/V4, MGCP 0.1/1.0, and SIP call control protocols. Also supports Cisco UCM using MGCP, H.323, or SIP.

G.711, G.729, G.729a/b, G.723.1, G.726, G.728, iLBC, G.722-These are standards-based compression technologies allowing transmission of voice across IP.

Supports the following signaling protocols:
FXO/FXS loop-start and ground-start signaling
E&M (wink, immediate, delay)
Inbound signaling (such as dual-tone multifrequency [DTMF], multifrequency support)
T1 and E1 channel associated signaling (CAS)
T1 and E1 PRI Q.931 user side and network side
T1 and E1 PRI QSIG
E1 MelCAS
E1 R2 CAS
T1 and E1 Transparent common channel signaling (CCS) (with multiple-D channel)
Country-specific signaling

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. Includes "Trader Turret" PLAR
Local/Advanced Voice Busy-Out-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 and FXO interfaces
Hunt Groups Across Cards-Calls can be forwarded automatically to the first available line
Integrated Add and Drop Multiplexer (Drop and Insert)-Performs add and drop multiplexing for voice within a dual-port voice network module. Eliminates the requirement, maintenance, support, and expense of using an external add and 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 (only supported on NM-HD-2VE)
Dial Plan Mapping-Simplifies configuration and management through automatic mapping of dialed phone numbers to IP addresses
Interactive Voice Response (IVR) Support-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.

Support FXS, FXO (includes CAMA), DID, E/M, BRI (S/T, NT/T), T1, and E1. (T1 and E1 only supported on NM-HD-2VE)

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 or 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 Cisco VIC port can be individually configured as an FXO or a CAMA port via Cisco IOS Software.
Per Port Disable-Allows disabling of any single port without affecting any other port on the same VIC or network module.
LED indicators for voice-processing resources and port status.

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.

Support serial data WAN access using T1/E1 or fractional T1/E1 network interface
N X 64 Kbps or N X 56 Kbps channel group data rates (T1:N=1 to 24, E1:N=1 to 31)
Supports up to 32 data channel groups with a total bandwidth of up to 2 Mbps
Supports integrated data WAN access and DS-0 voice channels on the same T1/E1

Channel Capacity-Supports up to 48 voice channels. See network module specifications below for further details.
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.
