Interfaces 81 and 160 (ASI 81 andASI 160)—High Density FXS Voice Gateways
The Cisco Integrated Communications System (ICS) 7750 brings the benefits of converged IP services to midmarket businesses and enterprise branch offices. The ICS 7750 is a versatile IP telephony and services solution that helps businesses harness the power of the Internet through converged applications enabling them to anticipate and respond to customer needs more efficiently. Call processing, voice applications and multiservice IP routing are integrated within the system chassis to deliver true convergence while enhancing system manageability. The modular system architecture enables expansion of call processing, routing capacity, and IP services to deliver system availability and scalability. The ICS 7750 gives customers the flexibility to choose the optimal configuration for their business environment, and allows them to increase profitability through improved customer interactions.
As companies adapt to the Internet economy, they need a solution that enables them to migrate
their voice communications to a converged IP infrastructure while protecting their investment
in existing analog telephone devices. The Cisco Analog Station Interface (ASI) 81 and 160 cards for the ICS 7750 provide businesses a cost-effective way to connect existing business communication devices such as fax machines, analog phones,
and teleconferencing devices to their converged
IP networks.
Product Description
The ASI 81 and ASI 160 are high-density foreign exchange station (FXS) voice gateway cards built from industry-proven Cisco hardware and Cisco IOS® Software technology to support both digital and analog voice trunks and station interfaces. The ASI 81 offers eight ports of foreign exchange station (FXS) along with one modular voice interface card/WAN interface card (VIC/WIC) slot. The ASI 160 offers greater analog density with 16 ports of FXS connectivity in a single slot. These two cards provide customers with the FXS density and flexibility to support the analog business communications devices in their offices.
The ASI 81 and ASI 160 are built on the same proven voice-over-IP (VoIP) technology used in the Cisco family of 1700, 2600 and 3600 series multiservice routers to ensure end-to-end interoperability between IP and TDM endpoints. The ASI cards enable customers to take advantage of all existing Cisco VoIP services and voice compression formats to meet quality voice and data bandwidth transmission requirements.
Each ASI 81 card has one modular slot that accepts existing Cisco voice interface cards (VICs) and WAN interface cards (WICs). This slot provides the same VIC and WIC support available on the Cisco 1700, 2600, and 3600 series routers, allowing customers to build upon current Cisco networks while maintaining interoperability and consistent end-to-end communication service between locations. This is particularly important when networking an enterprise branch office throughout a distributed enterprise network.
Data Connectivity
The WICs support a wide range of services, including synchronous and asynchronous serial, Integrated Services Digital Network Basic Rate Interface (ISDN BRI), and serial with digital service unit/channel service unit (DSU/CSU) options for primary and backup WAN connectivity.
Voice Connectivity
The VIC cards include support for Foreign Exchange Office (FXO) for analog central office trunks in North America, Asia, Europe and Australia; Foreign Exchange Station (FXS) for analog station devices; ear and mouth (E&M) for analog tie line support; analog direct inward dial (DID); T1 Channel Associated Signaling (CAS) and Primary Rate Interface; and E1 PRI and BRI for digital central office trunks. This support makes it simple to link the Cisco ICS 7750 to the Public Switched Telephone Network (PSTN) and existing private branch exchanges (PBXs), as well as the most common analog devices (including fax machines and teleconferencing stations). The modular design enables the ASI 81 card to deliver new voice interface support, as the technology becomes available in the marketplace.
Voice Services
For IP voice networks, the ASI 81 and ASI 160 cards support G.711, G.726, and G.729 codecs to enable interoperability between different IP endpoints, such as analog devices and Cisco IP phones. Configurable digital signal processing (DSP) resource modules, called packet voice/data modules (PVDM), provide the codec compression and transcoding services to support different voice and data network traffic configurations, particularly for branch offices using VoIP.
ASI support for Cisco IOS technology will ensure that customers keep up with the latest in VoIP advances to adapt to changing business communication needs.
Key Benefits
Versatile Voice/Data Connectivity and
Cisco IOS TechnologyThe modular VIC and WIC design enables businesses to configure the ASI 81 to support their specific voice and data communication needs today, with the ability to easily add bandwidth, voice trunk capacity, new Cisco IOS services, and redundancy as business needs change.
Scalable, High-Density Capacity
Two high-density FXS cards offer choice to meet their system-wide analog station requirements. The universal card design allows customers to deploy multiple ASI cards to scale to their needs.
Simplified Management
The ASI 81 card enables voice and data services to be consolidated over a single card, simplifying management and support.
Industry-Proven Cisco IOS Software
Delivers AvailabilityThe proven Cisco IOS technology delivers reliable, end-to-end connectivity over the PSTN and WAN between branch offices, customers, and partners. Field-replaceable VIC and WIC cards increase system connectivity uptime.
