teleconferencing,voice-enabledWeb commerce, and content delivery.

This creates new business partnering opportunities for VoIP service

providers. The standards-based Cisco AS5350 enables

interconnection between telephony ASPs and VoIP network

infrastructure providers to bring complete solutions to end users.

Uniﬁed Communications

Uniﬁed communications uses the IP infrastructure to unify the

communications methods that were previously disjointed—e-mail

applications, fax machines, voice-mailsystems, cellular phones, and

Web communications. This gives users a common method to both

access messages and initiate real-time communications—all using

familiar devices.

Service providers can implement uniﬁed communications solutions

by deploying Cisco AS5350ssbetween traditional PSTN or wireless

networks and their packet-based telephony network and adding

application servers that support uniﬁed communications services.

Cisco has partnered with several industry-leading developers to

provide uniﬁed communications solutions. Following are some of

the cost-effective services that carriers can offer to build brand

identity and increase customer loyalty while reducing turnover:

• Uniﬁed voice mail, fax, and e-mail

• Voice, fax, and e-mail retrieval by phone

• Integration of electronic documents with faxes

• Personal message agents

• Caller access to Web-based content through VoiceXML-enabled

applications

• Never-busy fax lines

• Broadcast fax

Service-Level Management

The Cisco AS5350 Universal Gateway supports RADIUS-based

Cisco RPM. This enables service providers to offer guaranteed port

availability across a shared infrastructure, which translates to

guaranteed service levels for their customers. In addition, Cisco

RPM offers the ability to ensure “fairness” across multiple

customers for the same shared ports when there is no service-level

guarantee.

Resource pooling can be conﬁgured on a per-gateway or

per-network basis. In the former case, customer proﬁles stored on

Cisco AS5350s determine how resourcesareallocated to each of the

wholesale service provider’s customers. Each customer is identiﬁed

based on a list of dialed numbers from DNIS. When network-wide

service levels are required, external Cisco Resource Policy

Management System (RPMS) software running on a Sun Solaris

server holds the customer proﬁlesandkeeps track of port utilization

across multiple Cisco AS5000 universal gateways and/or other

vendors’ RADIUS-compliant gateways. When the Cisco AS5350

receives an incoming call, the Cisco RPMS determines whether the

call should be accepted based on information in the customer

proﬁle.

Cisco AS5350 Architecture

The Cisco AS5350 Universal Gateway provides all the system

components that service providers have come to expect from

carrier-class products as well as all the routing, WAN, and QoS

features that are the hallmark of Cisco routing products. The Cisco

AS5350 uses a 250-MHz RISC microprocessor with 256K

secondary and 2-MB tertiary caching. The main CPU in the Cisco

AS5350 is also used in the Cisco 7200 Series Network Processing

Engine 300. The Cisco AS5350 offers the option of a redundant

power supply or single power supply. The Cisco AS5350 has three

slots that can contain trunk and universal port feature cards. The

Cisco AS5350 architecture uses distributed processing between the

feature cards and the motherboard to optimize the processing path

for unparalleled performance (See Figure 2).

Egress Interfaces

The Cisco AS5350 Universal Gateway provides three redundant

WAN backhaul methods for moving packets out to the network:

• Two 10/100 autosensing Fast Ethernet ports

• Two 8 Mbps serial ports

• Any T1 or E1 port on a trunk feature card

Ingress Interfaces

The Cisco AS5350 Universal Gateway accepts and consolidates all

types of trafﬁc, including dial-in analog, digital ISDN, wireless,

voice, Global System for Mobile Communications (GSM) V.110

calls, and fax calls. The CiscoAS5350 supports the following trunk

feature cards as ingress interfaces:

• Two-port CT1/CE1/PRI termination

• Four-port CT1/CE1/PRI termination

• Eight-port CT1/CE1/PRI termination

Additionally, the two serial ports on the motherboard and trunk

feature cards can be used for leased-line termination and

aggregation using Frame Relay, HDLC, or PPP.
