This chapter provides physical and functional overviews of the Cisco AccessPath-TS3 Model 531 Integrated Access System.
This chapter includes the following sections:
The Cisco AccessPath-TS3 Model 531 Integrated Access System is a scalable, high-density dial system designed to terminate a large number of incoming mixed digital Integrated Services Digital Network (ISDN) and analog calls. The Cisco AccessPath-TS3 Model 531 system provides dial access for service providers deploying large-scale (140 or more) hybrid access ports at a central site. Through its distributed architecture, the system supports remote node or remote local area network (LAN) applications using either asynchronous modem or ISDN technology.
The Cisco AccessPath-TS3 Model 531 system provides a remote access solution for the inter-exchange carrier (IXC), regional Bell operating company (RBOC), Internet service provider (ISP), competitive access provider (CAP), and large Enterprise markets. It integrates high-end access servers, Ethernet switches, and routers into a single Electronic Industries Association (EIA)-standard rack cabinet.
The Cisco AccessPath-TS3 Model 531 system accommodates both scalable dial-port counts and high-performance backbone routing in a distributed system architecture. The enhanced performance meets the reliability and serviceability requirements of point-of-presence (POP) administrators, enabling them to minimize downtime and service costs.
Processing tasks—such as answering and terminating calls—are divided among several CPUs, increasing overall system call processing and throughput performance. By providing alternate data paths from each access server to 1 or 2 high-distribution routers, the Cisco AccessPath-TS3 Model 531 system provides full redundancy for mission-critical data.
The Cisco AccessPath-TS3 Model 531 system integrates the latest access server, switching, and advanced routing features of Cisco IOS software. Its built-in System Controller facilitates the management and remote configuration of the system.
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
The Cisco AccessPath-TS3 Model 531 Integrated Access System comes in 4 standard configurations:
Each configuration is built around a Cisco-specified switching and routing infrastructure, which can be expanded in order to support greater call volumes. The more powerful your infrastructure, the greater the number of Cisco AS5300 access servers you can install in your system, thereby expanding your capacity to handle incoming calls.
You can scale your existing Cisco AccessPath-TS3 Model 531 system configuration by adding a Catalyst 5002 switch, a Cisco 7206 router, or multiple Cisco AS5300 access servers to your system. You can fully upgrade from one configuration to another, or modify an existing configuration by adding Cisco AS5300 access servers.
Each configuration contains a switched infrastructure, using different combinations of Cisco's Ethernet switching module and the Catalyst 5002 switch. The switched system fabric speeds the processing of incoming requests, and transfers them to the Cisco 7206 router or routers.
All configurations include:
A Cisco 3640 System Controller provides console management functions for the Cisco AccessPath-TS3 Model 531 system, while multiple Cisco AS5300 access servers supply the dial front-end interface. Each access server contains a series of ports arrayed as points of entry for calls arriving at your site.
Depending upon the configuration, either 1 or 2 Router Shelves are installed in the system. These provide process server and backhaul functions. The routers also provide load balancing when demand is heavy; in Midrange and High-End configurations, the presence of 2 Router Shelves leads to the activation of a failover path should a single router fail.
The following sections describe each of the 4 Cisco AccessPath-TS3 Model 531 system configurations in more detail.
The Cisco AccessPath-TS3 Model 531 system Entry configuration contains:
The primary data paths run from the access server ports to the primary dual Ethernet switch module using full duplex autosensing 10BaseT ports. The switch uses Fast Ethernet (100BT) to transmit data to the Router Shelf router.
The Entry configuration is the base system configuration for the Cisco AccessPath-TS3 Model 531 system. You can upgrade within its defined parameters by adding Access Server Shelves until you reach a total of 7, or upgrade (scale) to the Midrange configuration by adding a Switch Shelf.
In addition to what is included with the Entry configuration (a Cisco 3640 System Controller, a single Cisco 7206 router), the Midrange configuration for the Cisco AccessPath-TS3 Model 531 system includes a Catalyst 5002 switch. The Midrange configuration can support 2 to 11 Cisco AS5300 access servers.
The Cisco AccessPath-TS3 Model 531 system Midrange configuration consists of:
In a Midrange configuration, the Catalyst 5002 switch provides the system's primary switching services. It can deliver more than 1 million pps (packets per second) throughput across a 1.2-Gbps backplane; the 24-port 10/100BaseT line card meets all 3T3 connectivity and switching requirements. The greater capacity of the Catalyst 5002 speeds the processing of incoming requests.
In addition to what is included with the Midrange configuration (a Cisco 3640 System Controller, a single Cisco 7206 router, and a Catalyst 5002 switch), the High-End configuration for the Cisco AccessPath-TS3 Model 531 system includes a second Cisco 7206 router. The High-End configuration can support 2 to 14 Cisco AS5300 access servers.
The addition of a second Cisco 7206 router provides load balancing for greater processing efficiency and system-level failover. The greater data processing power it provides allows for the addition of Cisco AS5300 access servers beyond the 11-access server limit of the Midrange configuration (to a limit of 14).
The Cisco AccessPath-TS3 Model 531 system High-End configuration consists of:
These components comprise the High-End Extended Configuration:
The placement and numbering of the Access Server Shelves is shown in Figure 1-2.
The Cisco AccessPath-TS3 Model 531 system includes the following features:
The Cisco AccessPath-TS3 Model 531 system arrives preracked, precabled, and preconfigured with default configurations. The preconfiguration is intended to improve customer success during system setup and reduce installation and operation costs. A great deal of the cost of any dial point-of-presence (POP) comes from the need to physically design, integrate, and test the equipment involved.
Each Cisco AccessPath-TS3 Model 531 system comes with a System Controller that provides console management of each device in the cabinet. This adds resiliency to the system by allocating a direct out-of-band console connection to every Cisco AccessPath-TS3 Model 531 system shelf.
You can use a terminal connection to the System Controller, command-line interface (CLI), and supplied custom or sample (typical) configurations to configure individual devices. You can also use AccessPath Manager (APM) software to configure system devices.
See the Cisco AccessPath-TS3 Integrated Access System Software Configuration Guide or the Cisco AccessPath Manager Configuration Guide to simplify software configuration.
The Cisco AccessPath-TS3 Model 531 system has no single point of failure. Operating time is maximized and the failure of individual components will not bring down the entire system. This applies to all Cisco AccessPath-TS3 Model 531 system configurations.
The Cisco AccessPath-TS3 Model 531 system provides guaranteed compatibility to networks that run Cisco IOS software. Cisco IOS software runs on most of the world's internetworks, both on Cisco routers and on many partners' platforms. Customers can leverage their current training and experience with Cisco IOS software to install, configure, and manage the Cisco AccessPath-TS3 Model 531 system.
Refer to the Cisco AccessPath-TS3 Integrated Access System Software Configuration Guide and the Release Notes for the Cisco AccessPath-TS3 Integrated Access System for additional information on Cisco IOS software in the Cisco AccessPath-TS3 Model 531 system.
With access servers, an Ethernet switch, and high-performance routers integrated into 1 system, the Cisco AccessPath-TS3 Model 531 system avoids incompatibility concerns that normally plague multivendor or multibox installations. The Cisco AccessPath-TS3 Model 531 system is precabled and individual components are configured with sample (typical) configurations, thereby guaranteeing interoperability.
You can scale your Cisco AccessPath-TS3 Model 531 system configuration to fit the changing needs of your company. It is possible to upgrade from 1 configuration to another; for instance, to scale from an Entry configuration to a Midrange configuration, or from a Midrange to a High-End configuration. You can even skip configuration levels when scaling; for instance, you can upgrade a Midrange system configuration to a High-End Extended configuration.
You can also upgrade an existing configurations without changing infrastructure devices by adding Cisco AS5300 access servers to expand incoming call handling capability. Alternately, you can upgrade the infrastructure devices without adding access servers, then add Cisco AS5300 access servers at a later time.
The Cisco AccessPath-TS3 Model 531 system's modular cabinet architecture also enables the rapid implementation of new technologies and hot swapping of new hardware components as they become available.
In addition to hardware scalability, the Cisco AccessPath-TS3 Model 531 system also includes software scalability through Cisco IOS software. The most common applications for which the Cisco AccessPath-TS3 Model 531 system is utilized are available as 3 orderable options:
T1 or E1 lines, supporting either ISDN PRI or channel-associated signaling (CAS), feed into the Cisco AccessPath-TS3 Model 531 system's Access Server Shelves. Each Access Server Shelf supports 4 T1/E1 connections. With a maximum configuration of 21 Access Server Shelves, the Cisco AccessPath-TS3 Model 531 system can accommodate up to 84 T1 or E1 connections.
| Connection | Interface | Maximum Number of Calls (21 Access Server Shelves) | Call Type |
|---|---|---|---|
T1
| PRI | 1932 | Analog or ISDN |
CAS1 a | 2016 | Analog | |
E1
| PRI | 2520 | Analog or ISDN |
CAS b | 2520 | Analog |
| 1CAS = Channel-Associated Signalling. |
An Access Server Shelf supports 4 T1/E1 connections. The calls arrive at the Cisco AS5300 access server ports and are sent on to the Switch Shelf, aggregated, multiplexed, and sent over a 100BaseT Fast Ethernet connection to the Router Shelf.
Figure 1-4 shows a Cisco AccessPath-TS3 Model 531 system Entry configuration set up for single-channeled interfaces.
If a PPP session analog call comes in to an Access Server Shelf from the cloud, it is framed and forwarded (multiplexed) to the Switch Shelf and forwarded to the Router Shelf.
Figure 1-5 illustrates a typical ISP environment using multichassis multilink PPP (MMP).
From the Router Shelf, customers can route calls to a wide variety of services. Calls can be routed to a WAN, or to another switch. If calls are forwarded through a WAN to a home gateway, the Router Shelf acts solely as a conduit, passing the data on to the home gateway where the call is answered.
