Figure 2. Business Broadband Connectivity with Cisco 1805
The Cisco 1805 Integrated Services Router is ideally suited for deployment where a small office is going to be connected to a larger network, most often with a secure VPN connection. These types of offices can include the following:
• Small Remote Office: The Cisco 1805 connects users in a small remote office, such as insurance agents, lawyer offices, or sales offices. With an always-on cable connection, Internet security is vital to protect business resources from malicious network attacks. VPN encryption and integrated security such as firewalls and intrusion prevention are critical to protect the network at every point. IT managers can centrally manage the remote site to quickly troubleshoot any network problems. For added reliability, customers can also use dial backup, through an external modem, if the primary broadband link fails.
• Teleworking: The Cisco 1805 is ideal for corporate teleworkers, offering high-speed HFC cable broadband access to the corporate network, as shown in Figure 3. The Cisco 1805 gives IT managers a standard platform to manage at the employee's home office. By integrating the cable modem into Cisco IOS Software, the Cisco 1805 provides expanded QoS features that adequately allow voice traffic precedence over data applications.
• Remote Call-center Agent: Similar to teleworking applications, this solution extends the Cisco IP Contact Center solution for telephone call-center agents to remote sites. With a high-quality, secure connection through the Cisco 1805, call-center agents can be located away from costly call-center facilities while maintaining secure and productive voice and data access from their home.
• Retail VPN: Retail stores migrating from dialup or satellite connections for point-of-sale transactions can use the Cisco 1805 to use low-cost broadband access with the required security to effectively use these public networks. They can then add multiple devices and applications to the store network to use the increased bandwidth. (Refer to Figure 4.)
• Ethernet Over DOCSiS: For small and medium businesses with multiple locations, the Cisco 1805 ISR can provide a dedicated connection between locations by leveraging an Ethernet over DOCSIS connection. Metro Ethernet Forum (MEF) 9 & 14 certified, the Cisco 1805 offers a low cost replacement for Private Line and Frame Relay T1 services with its Ethernet over DOCSIS capabilities.
For Cable Service Providers, this solution enables business services across multiple footprints, with minimal OpEx costs, as no changes to the CMTS are required to provision MetroE over DOCSIS using the Cisco 1805 ISR. Existing HFC plant can be used to deliver business class Ethernet based services, maximizing ROI on the existing plant.
In addition to providing an excellent primary WAN link, the Cisco 1805 is also well-suited to be used as a secondary WAN link to offload Web traffic directly to the Internet, provide a redundant option for a primary link in case of failure, or provide load balancing with a xDSL or other type of link, as shown in Figure 4.
