Introducing VoIP Gateways (Introducing Voice over IP Networks) Part 3

Cisco AS5850 Universal Gateway

The Cisco AS5850 Universal Gateway, as illustrated in Figure 1-21, is a high-density, carrier-class gateway with high capacity and availability. The AS5850 Universal Gateway is specifically designed to meet the demands of large service providers by supporting up to five channelized T3s (CT3s), 96 T1s, or 86 E1s of data, voice, and fax services on any port at any time. It offers high-availability features such as hot swap on all cards, load-sharing and redundant hot-swappable power supplies, redundant route-processing cards, and CAC to ensure 99.999 percent availability.

Cisco 827-4V ADSL Router

The Cisco 827-4V ADSL Router, shown in Figure 1-22, provides business-class functionality for small businesses, small remote offices, and corporate teleworkers using Cisco IOS technology. It enables service providers and resellers to increase service revenue by supporting features for business-class security, integrated toll quality voice and data, differentiated service classes, and managed network access. These features, along with the manageability and reliability of Cisco IOS, provide mission-critical networking.

With the software upgradeable platform of the 827-4V ADSL Router, service providers and resellers can increase revenue by offering DSL services today and provide value-added services as their customers’ technology needs grow. The Cisco 827-4V ADSL Router is a member of the Cisco 800 Series Routers. Go to http://www.cisco.com/go/800 to learn more about the Cisco 800 Series Routers.

Cisco ATA 186

The Cisco Analog Telephone Adaptor 186 (ATA 186), as depicted in Figure 1-23, is a handset-to-Ethernet adaptor that allows traditional telephony devices to function as VoIP devices. Customers can use IP telephony applications by connecting their analog devices to Cisco ATAs.

Figure 1-23 Cisco ATA 186

The ATA 186 supports two voice ports, which each have an independent telephone number and a single 10BASE-T Ethernet port. This adaptor can make use of existing Ethernet LANs, in addition to broadband pipes such as DSL, fixed wireless, and cable modem deployments.

The Cisco Analog Telephone Adaptor 180 Series products are standards-based IP communications devices that deliver VoIP terminations to businesses and residences. Go to http://www.cisco.com/go/ata186 to learn more about the Cisco ATA 186.

Cisco 7200 Series Routers

Cisco 7200 Series Routers, an example of which is shown in Figure 1-24, are service routers for Enterprise Edge and Service Provider Edge applications. These compact routers provide serviceability and manageability coupled with high-performance modular processors such as the Cisco 7200 Network Processing Engine NPE-G1 (NPE-G1).
