Feature Description and Benefits
• 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 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.
Voice Port Interfaces
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)
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 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
• 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.
Data Features (Only Supported
on NM-HD-2VE)
• 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
High-Performance Flexible Digital
Signal Processor (DSP) Architecture
• 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.
