Feature Description and Benefits
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/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, and E1 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.
●
Per port disable: Allows disabling of any single port without affecting any other port on the same VIC or NM.
●
LED indicators for voice processing resources and port status.
Fax and Modem
●
Fax and modem passthrough: 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
●
Supports 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.
●
Dual clocking domain: Supports a second clocking domain for one T1/E1 data only trunk, independent of the
primary clocking domain used by other T1/E1 and BRI ports resident within a single NM-HDV2 module.
High-Performance Flexible
DSP Architecture
●
Channel capacity: Supports up to 120 medium-complexity voice channels. See NM specifications below for
further details.
●
Flexi-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.
●
DSP sharing: Supports the ability to share DSPs among multiple NM-HDV2 modules within a single Voice
Gateway Router.
