Feature Description and Benefits
• 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.
