Cisco SRP 500 Series Services Ready Platforms
Flexible, Cost-Effective Customer Premises Equipment for Small Business
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
Cisco SRP 500 Series Services Ready Platforms include:
●
Embedded intelligence to support a variety of high-quality voice, data, security, wireless, and application
services.
●
Integrated voice ports powered by 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. One port can be designated as the network
edge, while 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) wireless data readiness with built-in USB modem drivers.
●
Interoperability with industry-leading DSL access multiplexers (DSLAMs), soft switches, and voice gateways to
enable scalable, end-to-end multiservice network deployments.
●
Support for industry-standard TR-069 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.
