Information About Cisco SM-X Double-Wide High Density Analog Voice Service Modules

Cisco High-Density Analog Voice and Fax Service Modules provide enterprises, managed services providers, and service providers the ability to directly connect public-switched telephone networks (PSTNs) and existing telephony equipment to Cisco 4000 Series Integrated Services Routers. The fixed-port (FXS) module provides Dual-Tone Multifrequency (DTMF) detection, voice compression and decompression, call progress tone generation, Voice Activity Detection (VAD), echo cancellation, and adaptive jitter buffering.

Cisco SM-X is a service module that can be inserted into the service module slots on Cisco 4000 Series Integrated Services Routers. Cisco SM-X provides VoIP connectivity to analog devices such as analog desk phones, analog conference room phones, fax machines and modems. Cisco SM-X provides a high number of FXS ports per RU on Cisco 4000 Series Integrated Services Routers.

The FXS port is used to connect analog phones, modems, fax machines, and speaker phones to an enterprise IP voice system, so you can use them as extensions to your Cisco or third-party IP call-control system. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. The Direct Inward Dialing (DID) port is used to provide off-premises DID connection from the central office. It serves only incoming calls from the PSTN. Caller ID is not supported in DID mode.

Platform and Software Requirements

Cisco SM-X double-wide service module is supported on Cisco 4000 Series Integrated Services Routers effective with Cisco IOS XE Release 16.7.1 and later.

Features and Benefits

The new generation of Cisco High-Density Analog Voice and Fax Service Modules improves upon the previous high-density analog and digital extension modules (EVMs). These improvements are as follows:

n On-board Digital Signal Processor (DSP)—The FXS service module contains an onboard DSP and don’t require the router to have a dedicated packet voice DSP module (PVDM) on the motherboard. The DSP on the voice module is necessary for the voice features. It also provides for echo cancellation of up to 128-ms echo-tail length for demanding network conditions.

n Support for Online Insertion and Removal (OIR)—The FXS service module supports Online Insertion and Removal (OIR), reducing the downtime required for new or replacement modules. The service modules can be inserted into the SM-X slot on Cisco 4000 Series Integrated Services Routers without powering off the router.

n FXS-E (extended loops) support—FXS ports on the new modules support FXS-E with the following details:

— Higher loop current (35 mA) to accommodate specialty phones

— Longer loop length for loops with 26 AWG wire, up to 11,000 feet (3400 meters)

— Higher ringing voltage (65 Vrms, no load)

Note: Switching between the modes requires reload of the ISR chassis.

In addition to the above features, the service modules supports the following features:

n Caller line ID

n G.711, G.729a, and G.726

n G722, iLBC, GSMAMR-NB, and Internet Speech Audio Codec (iSAC)

n Fax detection, pass-through, and relay (T.38)

n Modem pass-through

n DTMF detection

n Echo cancellation

n Voice activity detection

n Comfort noise generation

n Real-Time Control Protocol (RTCP)

n Acoustic shock protection

n Real-Time Transport Protocol (RTP)

n RFC 4733 Digit Relay

n Noise reduction is on the roadmap

The FXS features include:

n Support for either FXS or DID functionality

n Message-Waiting Indicator (MWI)

n Cable detection: GR909 line test

Analog Phone Connectivity

Cisco High-Density Analog Voice and Fax Service Modules are ideal for analog phone deployments ranging from centralized to sparsely concentrated or distributed topologies. Cisco 4000 Series Integrated Services Routers offer many supplementary analog calling features, depending on the call control and signaling type used. All supplementary analog features are supported through the FXS service module. The analog interface on Cisco 4000 Series also supports Feature Access Codes (FACs) for invoking supplementary services.

Fax and Modem Connectivity

FXS ports on the Cisco High-Density Analog Voice and Fax Service Modules support fax machines and modems. When using fax machines, the gateways support T.38 fax relay and fax pass-through. T.38 fax relay technologies allow transfer of faxes across the network with high reliability using less bandwidth than a voice call. All modems can be connected to the Cisco VG Series Gateways and are transferred over the network using modem pass-through.

Protocols Supported

The voice gateways support the following protocols:

n SCCP

n H.323v4

n MGCP

n SIP
