Flexibility in Deploying New Services

Demand for new services can be easily accommodated with the Cisco AS5850 Universal Gateway whether the initial business opportunity

is wholesale dial, prepaid calling card, global long distance, or any other application. The capability to use the gateway in multiple service

environments provides unprecedented capital-investment protection. The access equipment can promptly adapt itself to any change in

business environment or demand for new services. The ability for service providers to offer innovative new services allows differentiation

from competition.

REMOTE-ACCESS SERVICES

Internet Connectivity

Enterprises and service providers need to extend network access to a broad range of remote users, including employees, customers, and

partners. Successful remote access means being able to connect these users from practically any location, almost transparently. The Cisco

AS5850 Universal Gateway, combined with Cisco IOS Software, meets these needs by extending the core infrastructure by providing

secure, reliable dial-in connections.

Data over voice bearer service (DoVBS) is used in areas where ISDN data calls are charged at a higher rate (or tariff) than ISDN voice

calls. The ISDN customer-premises-equipment (CPE) device (terminal adapter or router) must support DoVBS operation; most popular

ISDN devices available today support DoVBS. The ISDN CPE device is programmed to signal all ISDN data calls as voice calls so that

these calls will be billed at the lower voice rate. Cisco Resource Pool Management (RPM) on the Cisco AS5850 is used to configure a

customer profile for DoVBS calls based on DNIS. This profile configures the Cisco AS5850 to treat all calls received on that number as

ISDN data calls, even if they are signaled as voice calls by the PSTN.

Wholesale Dial

Many ISPs and content providers (or “portals”) must provide dialup Internet access as part of their service packages, and enterprise

companies want to offer “private-label” Internet access to promote their brands. However, they do not have the experience, personnel, time,

or money to build out a dialup-access infrastructure, or they cannot build it quickly enough, particularly when expanding into new regions.

Service providers can now take advantage of this opportunity through Cisco wholesale dial solutions.

The Cisco wholesale dial outsourcing solution delivers “virtual port” capability in Cisco remote-access servers. Coupled with sophisticated

port-policy management that guarantees port availability to wholesale customers, Cisco helps carriers and ISPs offer unique services that

bring incremental revenue while holding down operations costs. The network infrastructure deployed for wholesale dial can also be used

to offer standard retail dialup services, plus other value-added services such as corporate dial outsourcing, Internet gaming, unified

communications, VoIP, and VPNs.

Access VPNs

The Cisco AS5850 Universal Gateway is ideally suited to providing wholesale dial services to both large corporations and ISPs that do not

want to support their own dial pools. With support for VPNs in Cisco IOS Software, service providers can take advantage of their existing

infrastructures to deliver local dialup access for users of enterprise networks.
