The Cisco High-Density Extension Module includes the following components:

• An 8-port extension module (part number EVM-HD-8FXS/DID)-Baseboard with 8 ports that can be configured individually for FXS or DID signaling

• Voice and fax expansion modules:

– A 4-port expansion module supporting BRI (NT and TE) (part number EM-4BRI-NT/TE)

– An 8-port expansion module supporting FXS and DID (part number EM3-HDA-8FXS/DID)

– A 6-port expansion module supporting FXO (part number EM-HDA-6FXO)

– A 7-port expansion module with 3 FXS and 4 FXO ports (part number EM-HDA-3FXS/4FXO)

Adding expansion modules to the Cisco High-Density Extension Module baseboard increases voice and fax session capacity. The modular design of the Cisco High-Density Extension Module provides maximum flexibility-plug in up to two expansion modules in any combination to build the Cisco High-Density Extension Module best suited for specific packet telephony network locations.
The Cisco High-Density Extension Module provides gateway services for Cisco Unified Communications using Cisco Unified Communications Manager with Survivable Remote Site Telephony (SRST) or Cisco Unified Communications Manager Express (UCME). Gateway services allow users to deploy networks that take advantage of investments in existing legacy telephony equipment while also deploying and integrating IP telephony. The network can operate at any point on the voice, video and integrated data spectrum-with the ability to add connections for both traditional telephony devices and IP telephony endpoints.

The Cisco High-Density Extension Module operates in the Extension Voice Module (EVM) slot on the Cisco 2821 and Cisco 2851 integrated services routers. The EVM slot supports additional voice services and density without consuming the network module slot on the Cisco 2821 or Cisco 2851.

Cisco 3825 and Cisco 3845 Network Module Slot

The High-Density Extension Module operates in any network module or enhanced network module (NME) slot on the Cisco 3825 and Cisco 3845 integrated services routers. The Cisco 3825 supports one Cisco High-Density Extension Module, and the Cisco 3845 supports one or two high-density extension modules.

Cisco 2900 and Cisco 3900 Service Module Slot

The Cisco 2900 and 3900 Series Integrated Services Routers support Network Modules and EVM Modules via an adapter (part number SM-NM-ADPTR).

High-Density Extension Module Digital Signal Processor (DSP) Resources

Packet voice DSP modules (PVDM2s) are used in combination with the Cisco High-Density Extension Module baseboard and its expansion modules. PVDM2s support multiple voice codecs, fax, conferencing, and transcoding services. PVDM2s are purchased separately and installed in the digital signal processor (DSP) module slots located inside the Cisco 2821, 2851, 2901, 2911, 2921, 2951, 3825, 3845, 3925, 3925E, 3945 and 3945E Integrated Services Routers. Initial orders for a Cisco 2821, Cisco 2851, Cisco 3825, or Cisco 3845 router that include a Cisco High-Density Extension Module should also include an appropriate number of PVDM2s.
In addition to PVDM2, Packet voice DSP modules (PVDM3s) are also available for the same applications described above. PVDM3s are used in combination with the Cisco High-Density Extension Module baseboard and its expansion modules. PVDM3s support multiple voice codecs, fax, conferencing, and transcoding services. PVDM3s are purchased separately and installed in the digital signal processor (DSP) module slots located inside the Cisco 2901, 2911, 2921, 2951, 3925, 3925E, 3945 and 3945E Integrated Services Routers. Initial orders for a Cisco 2901, 2911, 2921, 2951, 3925, 3925E, 3945 and 3945E router that include a Cisco High-Density Extension Module should also include an appropriate number of PVDM3s. Note that PVDM3s are not supported on the ISRs. PVDM3s are supported only on the Cisco 2900 and 3900 series platforms.
PVDM2 and PVDM3s can coexist on the Cisco 2900 and 3900 series platforms as long as both types are not installed on the motherboard at the same time. If PVDM2 are detected on the motherboard with PVDM3s, then PVDM2s will be deactivated, allowing only PVDM3s to be used. If PVDM2s are detected in SM slots and PVDM3s are installed on the motherboard, then both will continue to function and coexist.

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.

ITU Standard Codecs such as G.729, G.729A/B, and G.711

These standards-based compression technologies allow transmission of voice across IP. G.711 is standard 64-kbps PCM modulation using either mu-law or a-law. For a complete list of codecs supported, refer to Table 3.

Silence Suppression and Voice Activity Detection

Bandwidth is used only when someone is speaking. During silent periods of a phone call (approximately 50 percent of the time), bandwidth is available for other traffic.

Comfort Noise Generation

To better simulate phone calls over voice networks, this feature reassures the phone user that the connection is being maintained, even when no voice packets are being transmitted.

Dial-Plan Mapping

Automatic mapping of dialed VoIP phone numbers to IP addresses simplifies configuration and management.

Dual Tone Multifrequency (DTMF) Tone Processing

This feature helps enable access to voice mail and interactive-voice-response (IVR) systems.

Fax and Modem Pass-Through

This feature allows fax and modem traffic to pass through a voice port.

Fax Relay

Fax relay provides a more robust protocol for fax transmission over packet networks. It includes support for T.38 and T.37 fax protocols.

Country-Specific Signaling

This feature transparently delivers customary phone signals to users, facilitating acceptance of new technology.

Autocalling and Private-Line Automatic Ring-Down (PLAR)

With this feature, a destination phone can be configured to automatically ring when the caller lifts the handset.

Hunt groups

Calls can be forwarded automatically to the first available line.

Battery Polarity Reversal Detection and Initiation

Detection of disconnect supervision and far-end answer supervision through battery polarity reversal provides a robust method of providing supervisory disconnect, especially for loop-start signaling on FXS and FXO interfaces.

Supervisory Disconnect

Signaling protocols such as loop start do not provide means for quickly detecting when the call initiation is terminated prior to call connection. Supervisory disconnect quickly makes this determination and frees valuable resources for other calls.
