Feature Description and Benefits
●
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,
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.
Additional Features
Cisco IOS Software and Platform Support
●
Fully supported via Cisco IOS Software command-line interface (CLI) including device configuration,
monitoring, link status, network security, Layer 2 and 3 protocol configuration and management, and call
history
Supported on all Cisco 2800, 2900, 3800 and 3900 Series unified communications routers
Traditional Circuit-Switched PBX Support
●
Verified PBX interoperability with Lucent Definity series (G3r), Nortel Meridian series (Option 11), Siemens
HICOM 330E, NEC NEAX 2400, Alcatel 4400, and Ericsson MD110. Other PBXs continue to be tested.
