Part of the Cisco Small Business Pro Series
Demand for managed services is expected to grow dramatically over the next four years, with small businesses--those with fewer than 100 employees--expected to make up more than half of this market opportunity. These companies may have complex IT needs but generally don't have the technical staff or expertise needed to keep up. They look to service providers for a flexible infrastructure and simplified management, along with better quality and reliability than they can achieve in-house. To meet this opportunity, service providers are transforming their networks, using services-ready platforms to deliver an array of profitable IP-based communications services.
Cisco® SRP 500 Series Services Ready Platforms are flexible, cost-effective fixed-configuration customer premises equipment (CPE) with embedded intelligence to enable service providers to create, provision, and deploy premium revenue-generating services--a variety of high-quality IP voice, data, security, wireless, and application services--to small businesses on an as-needed basis. These platforms will help enable service providers to deliver differentiated, converged service offers that increase bandwidth usage and average revenue per user while reducing customer churn.
Product Overview
The Cisco SRP 521W Services Ready Platform includes:
- Embedded intelligence to support a variety of high-quality voice, data, security, wireless, and application services;
- Integrated voice ports and an industry-leading voice Session Initiation Protocol (SIP) stack to deliver clear, high-quality voice service;
- Integrated stateful packet inspection (SPI) firewall and high-speed IP Security (IPsec) VPN capabilities with support for Triple Data Encryption Standard (3DES) to help keep small business data safe;
- 4-port managed Ethernet switch to connect devices in the office. VLAN support allows for highly secure segmentation of network resources;
- Integrated 802.11n wireless access point to enable employees to connect to the network while away from their desks;
- Third-generation (3G) readiness with built-in 3G USB modem drivers;
- Interoperability with industry-leading soft switches, and voice gateways to enable scalable, end-to-end multiservice network deployments;
- Support for industry-standard TR-069, TR-104, and XML-based provisioning for zero-touch deployments;
- Easy integration with other Cisco Small Business Pro Series products to enable adaptability as customer needs change.
Features and Benefits
Cisco SRP 500 Series Services Ready Platforms are flexible, cost-effective CPE devices for small businesses that meet the needs of service providers through:
- Embedded intelligence to support concurrent, premium revenue-generating services such as voice, data, security, and applications. Service providers can easily create and provision a variety of service offerings, adding or removing them remotely as their customers' needs change;
- Industry-leading SIP stack that delivers an advanced implementation of standard voice coding algorithms for clear, high-quality voice under diverse network conditions, along with support for common telephony features such as voicemail, fax, and interactive voice response systems;
- Interoperability with industry-leading soft switches, and voice gateways that enable service providers to deploy highly efficient, scalable end-to-end multiservice networks;
- Standards-based provisioning, with support for TR-069, TR-104, and XML, that reduces operating expenses by enabling zero touch deployments, eliminating the need for highly skilled technicians and costly truck rolls to deploy new services;
- Compact design that integrates voice, data, switching, wireless, security, and application support in a desktop device that is ideal for simple, space-saving small business deployments;
- Competitive pricing with support for premium services that reduces capital expenses, warehousing costs, and the need for complete equipment upgrades when service requirements change.
