This section describes the available Cisco access servers.
The Cisco AS5300 universal access server is a versatile data communications platform that provides the functions of an access server, router, and digital modems in a single modular chassis. The access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, as well as medium- to large-sized sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides you with a clear, simple, and easy migration path from today's analog dial access services to tomorrow's digital dial access services.
The access server consists of the following components:
Figure 26 and Figure 27 show the front and rear panels of the Cisco AS5300 universal access server.
The access server includes three slots (see Figure 27) in which you can install a combination of feature cards.
In any one slot you can install your choice of:
In the remaining two slots you can install your choice of:
You can install a quad T1/PRI card (Figure 27) in any unpopulated slot of the access server chassis.
The quad T1/PRI card includes four RJ-45 ports. Cables are not included with the card.
A 10-position rotary switch allows the user to chose which of the four ports is selected for monitoring through the bantam jacks (TXMON, TXIN, TXOUT and RXMON, RXIN, RXOUT).
You can install a quad E1/PRI card (Figure 27) in any slot of the access server chassis.
The quad E1/PRI WAN card includes four RJ-45 ports for terminating 120-ohm balanced lines or 75-ohm unbalanced lines. Cables are not included with the card.
A 10-position rotary switch allows the user to chose the number of ports that are terminated as 75-ohm unbalanced lines. Jumper settings on the card can be used to configure the 75-ohm unbalanced ports so the receive shield is connected to ground..
You can install up to two MICA carrier cards (Figure 27) in any unpopulated slot of the access server chassis. Each MICA carrier card includes 10 slots in which you can install 6-port modem modules. Each 6-port module includes 6 modems. Therefore, in a fully populated MICA carrier card, you can have up to 60 modems. Or, in a fully populated access server chassis, you can have up to 120 modems.
You must install the 6-port modem modules in the MICA carrier card. The 6-port modules cannot be used as stand-alone cards and they cannot be installed in Microcom carrier cards.
Utilizing Cisco's breakthrough MICA DSP technology, network managers are assured of the highest performing, highest flexibility, standards compliant access platform for today and tomorrow. Future technologies and enhancements, such as ITU 56k, are easily implemented via a simple software upgrade. In addition, future software enhancements will provide functionality beyond simple modem call termination.
These DSPs are incorporated into the MICA 6-Port modem module. As outlined above in the carrier card section, these modem modules are configured with a carrier card for a total of 60 ports per card, and two cards per chassis.
The Cisco AS5300 provides complete centrally managed modem capabilities, key requirements for service providers and enterprises building large dial-in pools. The modems can be managed via the same tools used to manage the rest of the network, providing network managers with one solution at a central management point. Cisco provides extensive modem management that no other vendor of access servers on the market provides. This includes the ability to directly access the modem at anytime (including when the modem is connected and on-line) to capture statistics, force a reset or check a modem's configuration. To take advantage of this modem management feature, customers must purchase an IOS "Plus" image as well as a Modem Management Technology License for the appropriate number of modems.
You can install up to two Microcom carrier cards (Figure 31) in any two slots of the access server chassis. Each Microcom carrier card includes two slots in which you can install any combination of 12-port modem modules, as described below.
The modules connect through the Microcom carrier card and the system backplane to a quad T1/PRI or quad E1/PRI card installed in the access server chassis. Data is transmitted or received on T1 or E1 lines connected to the quad T1/PRI or quad E1/PRI card and then routed to the 12-port modules installed in the Microcom carrier card.
The access server supports any combination of the following 12-port modules:
You must install the 12-port modules in the Microcom carrier card. The 12-port modules cannot be used as stand-alone cards and they cannot be installed in MICA carrier cards.
Either an AC or DC power supply is available. The power supply provides DC power to the installed feature cards via connectors on the backplane.
The internal power supply is a four-output switching power supply with power factor correction and regulated outputs.
The AS5300 is managed via the easy to use CiscoView Application. Using a point-and-click Graphical User Interface, Network Managers can monitor the real-time performance and call status of their Universal Access Server. Multiple displays, including a physical and logical view, provide in-progress call status information for both ISDN and Analog K56-Flex Modem calls, PRI, Channelized Line and Ethernet interface statistics.
Useful administrative tools, including the ability to capture individual caller statistics and information such as IP address per port, remote phone number, etc. are quickly monitored and reported via easily accessible call-information screens.
Product numbers for the Cisco AS5300 are provided in Table 25.

The Cisco AS5200 universal access server (see Figure 37) is a versatile data communications platform that provides the functions of an access server, a router, and digital modems in a single modular chassis. The Cisco AS5200 is intended for Internet service providers (ISPs), telecommunications carriers, and other providers that offer managed Internet connections, as well as small- to medium-sized sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls in the same chassis simultaneously, the Cisco AS5200 provides you with a clear, simple, and easy migration path from today's predominantly analog dial-in services to tomorrow's digital dial-in services. Furthermore, the AS5200 can be deployed in Global Systems for Mobile Telecommunications (GSM) cellular environments to provide remote access to mobile users.
The unique combination of Cisco IOS software and the Cisco AS5200 universal access server mixed-media platform results in a host of benefits for network managers.
The Cisco AS5200 universal access server is the first product in an entire line of universal access solutions offered by Cisco Systems. Universal access is more than just providing connections from ISDN or asynchronous modems; it is also the ability to perform the following:
The Cisco AS5200 universal access server provides universal access via a single chassis for small- to medium-sized dial-in sites, and access to larger sites via logically stacked chassis. This access allows you to save money by using the same trunk line for both asynchronous and ISDN calls, which reduces the number of system components and operational costs. The latest hardware option (V.110 Port Module) allows mobile users to access the corporate network or the Internet through GSM cellular networks.
The Cisco AS5200 universal access server also supports the widest array of networking and routing protocols available in the industry. Not only does the Cisco AS5200 universal access server support remote node and remote LAN dial-in protocols, but it also supports all Cisco IOS software routing protocols.
The scalability and manageability of a network are a concern for all network managers. With Cisco IOS Software Release 11.2, the Cisco AS5200 universal access server will support call aggregation among multiple chassis. Using multichassis multilink PPP, Cisco Systems has developed the means to aggregate multiple calls terminated on multiple servers. Network managers will have the ability to stack multiple AS5200 universal access servers for high-density applications.
Another important feature of scalability is managing the components of a growing network. The Cisco AS5200 universal access server supports both the command-line interface and the CiscoWorks GUI. Network managers can collect statistics from the modems, upgrade your modem software, group modems for configuration, soft- or hard-busy-out modems, and even monitor call-in-progress signals from individual modems, all from the same platform they already use to manage their routers.
The Cisco AS5200 complements Cisco IOS Virtual Provide Dial-up Networks (VPDN) features to provide substantial cost savings to enterprise and small/medium businesses by eliminating the need for expensive private leased lines. Customers can also benefit by outsourcing non-strategic activities while maintaining security and control. Service providers may also benefit by leveraging the existing infrastructure to generate additional revenue opportunities. Furthermore, since remote access calls are terminated locally, they also reduce the amount of telephony switching capacity consumed by RBOCs, carriers, or PTTs (dial off-load).
Cisco IOS software provides tight security in the core network, and with the Cisco AS5200 universal access server, extends that core security to mixed-media dial-in sites. Some of the features supported by Cisco IOS software are access lists, violation logging, Terminal Access Controller Access Control System (TACACS+), and Remote Access Dial-in User Service (RADIUS).
Cisco IOS software offers a wide array of WAN optimization features, including compression, routing filters, snapshot, bandwidth-on-demand, and dial-on-demand routing. These features help control WAN costs--the largest single cost of operating an internetwork.
In multibox, multivendor installations, incompatibility is an issue. Because the Cisco AS5200 universal access server combines the CSU, modems, routers, and access server components in one chassis, you get seamless interoperability among its integrated components. Fewer individual pieces of equipment reduce configuration and incompatibility issues.
The following cards and port modules are available for the Cisco AS5200 universal access server.
Each Cisco AS5200 universal access server must have one dual T1/PRI or E1/PRI card installed in the chassis. The system does not support more than one of these cards. These cards provide the channelized interface necessary to handle digital and analog calls that are terminated in the unit.
The T1 card is software switchable between channelized T1 and ISDN PRI. You can configure the T1 card so that both ports are channelized T1, both ports are ISDN PRI, or one port is channelized T1 and one port is ISDN PRI.
If you configure the T1/PRI or E1/PRI card to support ISDN PRI, it can terminate analog modem calls, GSM cellular data calls, and ISDN BRI calls on the same PRI span. Based on ISDN Q.931 call bearer information, Cisco IOS software routes calls to the appropriate port module for termination. For example, analog calls are terminated by the modem modules, GSM calls are serviced by the V.110 Terminal Adapter (TA) modules, and ISDN calls are sent to the PPP termination engine. This flexibility allows providing one telephone number to users for analog, GSM, and ISDN data calls
The carrier card can hold up to two 12-port modules. You can configure a Cisco AS5200 universal access server to support up to two carrier cards. If you order a Cisco AS5200 universal access server with a T1/PRI card with modems or TA option, it must have one carrier card for each two port modules ordered. If you order a Cisco AS5200 universal access server with an E1/PRI card with modem or TA option, a single port module can be plugged directly into the E1 card, which provides an extra port module slot. This enables a Cisco AS5200 universal access server with an E1/PRI card to support up to 60 modems or 60 V.110 TAs, whereas a Cisco AS5200 universal access server with an T1/PRI card can support up to 48 modems or V.110 TAs.
The Microcom 12-port modem module supports Rockwell's K56Flex technology. Each modem module contains 12 modems. These modems are Flash based, so you can upgrade their microcode remotely. You can order up to two of these modules with a carrier card. Modems can be upgraded via software from basic modem configuration to a managed modem configuration. Managed modems support real-time call-in-progress monitoring.
The following conditions apply to the 56K modules:
The V.110 12-port module includes onboard terminal adapters that can terminate up to 12 V.110 bit rate adapted digital calls. Bit rate adaption protocols map the PC communications port speed to the faster data rate (64000 bps) of Integrated Services Digital Network (ISDN) B channels. The V.110 module supports a maximum data rate of 19200 bps or lower on all ports simultaneously.

The Cisco 2500 access server series represents Cisco's low cost entry into the access server marketplace. Two new products have recently been added to this family; the dial optimized AS2509-RJ and the AS2511-RJ. The Cisco 2500 access server series gives users the ability to connect asynchronous devices such as dumb terminals, modems, router consoles, slot machines, and ISDN TA's into a routed network. This product family new features that make them easier to use then ever, and they run the same Cisco IOS software that runs the backbone of the Internet on a high-performance router engine. It also gives users integrated synchronous serial ports to backhaul routed traffic through T1/E1 lines.
The Cisco 2500 access server series (see Figure 38 through Figure 41) provide a variety of models designed for small office and remote site environments. Each model is a fixed-configuration router that supports at least two interface types. Each access server comes standard with Flash EPROM technology for simplified software maintenance. For software, the Cisco 2500 access server series offer a wide choice of feature sets, so you can select the appropriate protocol set for your network environment. These feature sets range from IP and bridging-only to a feature set containing the full array of Cisco's software functionality.
Table 27 lists the product numbers for the Cisco 2500 access server series.
The Cisco 2500 access server series runs on the same Cisco IOS that runs the backbone of the Internet.

The Cisco IOS software available for the Cisco access servers is described in the following sections:
Cisco access servers support the following software releases:
Note that all Cisco AS5100 access server cards (AS51-16A-E) must use the same Cisco IOS release level and feature set.
This section describes the Cisco IOS feature sets available for Cisco access servers.
Cisco access servers offer the following types of feature sets:
The Cisco IOS feature set tables use the following conventions to identify features:
Software feature packs consist of CD-ROMs that contain Cisco IOS software feature set images and a Windows 95 application, which loads the images onto a router.
Software feature packs are available for most of the Cisco IOS Release 11.2 feature set images. Table 27 and Table 27 list the product numbers for feature sets and feature packs available in Cisco IOS Release 11.2. Software feature packs are only available for Cisco IOS Release 11.2.
For more information about software feature packs, see the section "Cisco IOS Feature Packs" in the chapter "Cisco IOS Software," earlier in the catalog.

There are two types of DRAM memory in the Cisco 2500 series and AS5100 access servers: primary and shared (packet). Primary memory is used to store the operating configuration, routing tables, caches, queues, and packets. Shared memory is used to store incoming and outgoing packets. In Table 33, the physical configuration column lists the amount of fixed DRAM and DRAM SIMM memory supported. The system usage column lists how the system allocates the total DRAM memory installed.
| Physical Configuration | System Usage | ||||
