•Double-density modem module (DMM)—Each double-density modem card contains 12 DMM SIMMS. Each DMM SIMM contains 12 digital modems.The Cisco AS5800 has the capability of terminating up to 1,344 modem connections when equipped with 10 double-density modem cards and 2 CT3 trunk cards.

•Egress interface—The router shelf interface to a network, such as the Internet or a corporate intranet or backbone. Supported interfaces include Fast Ethernet, HSSI, FDDI, and ATM interfaces.

•Front and rear—The front of the dial shelf is defined as the card-insertion side and provides access to the line cards and the blower assembly. The rear or back of the dial shelf is defined as the power-entry side and provides access to the filter module and two power-entry modules.

•

•

I/O controller card—The router shelf card containing the system I/O controller.

Ingress interface—Dial shelf cards that connect to the telco network and contain the necessary functionality to terminate a telco connection. The ingress interface terminates digital calls at the dial shelf. The Cisco AS5800 currently supports CE1, CT1 and CT3 ingress interfaces.

•Maintenance bus (MBus)—Used in the dial shelf to monitor –48 VDC from both DC power supplies using analog isolation circuits.

•Modem card—A printed circuit board that connects to the dial shelf backplane and contains hex modem module SIMMs. Its primary purpose is conversion between pulse code modulation (PCM)-encoded analog bitstreams on the backplane TDM bus and packetized digital data on the backplane interconnect. The modem card terminates incoming analog calls at the dial shelf.

•

•

Network processor card—The router shelf card containing the network processing engine (NPE).

Online insertion and removal (OIR)—A feature that allows you to insert and remove modules and cards without interruption to service while the system is powered on.

•Pulse code modulation (PCM)—A specific way of representing an analog waveform in digital format.

•

•

Power-entry module (PEM)—A –48 VDC power supply module.

Router shelf—The host route processing functionality for the dial shelf. The router shelf carries data between the dial shelf and an external network, such as the Internet. Full Cisco IOS software functionality is provided on the router shelf.

•Time-division multiplexing bus (TDM bus)—A dial shelf proprietary serial telecommunications backplane that enables multiple channels of data to be transmitted over the same medium. The TDM bus connects a DS0 channel (from the ingress interface) to an individual modem on the modem card.

•Trunk card—A printed circuit board that connects to the dial shelf backplane and contains trunk circuitry, such as CT1 or CE1 interfaces. The trunk card acts as the ingress interface through which all calls are received, and terminates incoming digital calls at the dial shelf.

AS5800 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
