PVDM2s can be installed on the motherboards of the Cisco 2900 and 3900 Series using special PVDM adaptor
cards (PVDM2- ADPTR). The existing NM-HDV2 modules with PVDM2s can be inserted into the SM slots of the
Cisco 2900 and 3900 series platforms using network adaptor cards (SM-NM-ADPTR).

Primary Features and Benefits
Table 4 summarizes the features and benefits of the Cisco High-Density Analog and Digital Extension Module for
Voice and Fax.
Table 4. High-Density Extension Module Features and Benefits Summary
Feature Benefit
Voice and Fax Over IP Voice and fax traffic is transport independent because IP traffic at Layer 3 can travel over any Layer 1 or Layer 2
media, including ISDN, leased lines, serial connections, Frame Relay, Ethernet, Token Ring, and ATM.
Connection Trunk The connection trunk creates a tie-line replacement structure while only consuming bandwidth only during a call
(digital-to-digital, digital-to-analog, or analog-to-analog capabilities).
Local Voice Busy-Out (LVBO) Users can automatically busy-out any desired voice trunk line to a PBX or PSTN when a direct WAN or LAN
connection to the router is down. This feature also allows busy-out of a far end trunk connection when configured for
connection trunk.
Caller-ID Support The module offers per-port configurable caller ID to phones connected to analog FXS voice ports using per call
unblocking if desired. It interoperates with analog phones, the PSTN, PBXs, Cisco Unified Communications Manager,
Cisco Unified Communications Manager Express (CME) and H.323 terminals such as Microsoft NetMeeting and IP
phones.
Call Admission Control
Using Response Time
Reporter (RTR)
This product uses RTR to determine latency, delay and jitter and to provide real-time Impairment/Calculated
Impairment Planning Factor (ICPIF) calculations before establishing a call across an IP infrastructure. RTR packets
emulate voice packets receiving the same priority as voice throughout the network. This is a superior method to data
and ping packets for determining congestion levels.
Voice and Fax Over the
Same Port
Ports can be used for both voice and fax traffic; no dedicated ports are required.
Works with Existing Phones,
Faxes, PBXs, and Key
Systems
No user re-training is required.
Call Control Signaling The product supports H.323 Versions 1, 2, 3, and 4; MGCP Version 0.1 and 1.0, and SIP call control protocols. The
Cisco High-Density Extension module interoperates with any Cisco Unified Communications Manager release using
the H.323 protocol. For MGCP, Cisco Unified Communications Manager Release 3.3(5), Release 4.0(2), and Release
4.1 add support for the Cisco High-Density Extension Module. Support is also available with Cisco Unified
Communications Manager Express (CME) Release 3.1. Cisco voice and fax modules are interoperable with numerous
emerging voice and videoconferencing applications.
High-Performance DSP
Architecture
PVDM2 modules used in combination with the Cisco High-Density Extension Module baseboard and its expansion
modules offer extremely low latency, which is essential for high-quality voice and fax services; the DSP architecture
also helps enable all critical functions to be handled in software, allowing for simple code updates, scalability and new
features. PVDM2s feature the latest DSP technology with support for conferencing and transcoding, higher call
densities per DSP, and more flexibility in channel allocation per DSP.
