Introduction to the Cisco AccessPath-TS3 Model 530 Integrated Access System
The AccessPath-TS3 system is a scalable, high-density dial system designed to terminate a large number (184 or more PRI, 192 or more modem) of mixed digital and analog calls (see Figure 1-1). The AccessPath-TS3 system provides dial access for service providers deploying large-scale hybrid access ports at a central site. It supports remote node or remote LAN applications that use asynchronous modem or Integrated Services Digital Network (ISDN) technology and includes the latest access server, switching, and high-end routing features available with Cisco IOS software.
The AccessPath-TS3 system integrates high-end access servers, Ethernet switches, and routers into a single Electronic Industries Association (EIA)-standard rack cabinet. It can terminate any combination of analog modem or digital ISDN calls for its incoming lines. Processing tasks—such as answering and terminating calls—are divided among several CPUs, increasing overall system call processing and throughput performance.
The AccessPath-TS3 system offers scalable dial-port counts and high-performance backbone routing in a distributed system architecture. The system provides the reliability and serviceability demanded by point-of-presence (POP) administrators who want to minimize downtime and service costs.

T1/E1 and Fast Ethernet backhaul interface support.
Automatic sensing of analog modem and digital ISDN calls across the entire rotary, regardless of size.
From 4 to 84 T1 PRI lines with integrated channel service units terminated in a single AccessPath-TS3 system. This allows up to 1932 simultaneous ISDN PRI calls to be terminated in a single T1-configured AccessPath-TS3 system. (For more information on call termination capacity, see Table 1-1.)
From 4 to 84 E1 PRI lines for customers who require E1 service. This allows up to 1260 simultaneous ISDN PRI calls to be terminated in a single E1-configured AccessPath-TS3 system. (For more information on call termination capacity, see Table 1-1.)
From one to six port adapter (PA) slots that take standard Cisco Versatile Interface Processor (VIP) PA cards.
PA slots can be configured to use a wide variety of Cisco port adapter cards, protecting customer investment and simplifying sparing.
Preconfiguration and precabling of hardware.
Preloaded custom or sample (typical) configurations of Cisco IOS software.
Full management of all components including access servers and their modems, switches, and routers by means of the Simple Network Management Protocol (SNMP), management information bases (MIBs), or the Cisco AccessPath Manager software.
Full management of all components by means of a single management interface when using the AccessPath Manager software. Parameters and statistics gathered across all the dial interfaces of the AccessPath-TS3 system are presented in one place.
Failsafe processing provided by the redundant data paths (via Ethernet and Fast Ethernet links).
Universal Access
The AccessPath-TS3 system allows dial point of presence (POP) managers to deploy large rotary groups in a short period of time. Cisco provides the AccessPath-TS3 system preracked, precabled, and preconfigured with custom or sample (typical) configurations. This preconfiguration facilitates system setup and reduces installation and operation costs. We recommend that you use Cisco AccessPath Manager software to simplify configuration.
The design of AccessPath-TS3 system networks that are customized for a specific installation is the responsibility of the customer.
Availability
The AccessPath-TS3 system has no single point of failure. Operating time is maximized and the failure of individual components does not bring down the entire system. This applies to all AccessPath-TS3 system confugurations.
Cisco IOS Software
The AccessPath-TS3 system offers 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 other platforms.) The AccessPath-TS3 system supports remote-node and remote-LAN dial protocols. You can use your current training and experience with Cisco IOS software to install, configure, and manage the AccessPath-TS3 system.
Preconfigured Hardware
When you purchase an AccessPath-TS3 system of any size (from 4 to 84 PRIs), we will install, wire, and configure the system for the most popular services available with Cisco IOS software. This reduces the cost of administering a POP because a great deal of the cost of any dial POP is in the physical design, integration, and testing of the equipment involved.
We consider connect rates, throughput, reliability, and manageability as mandatory features of any properly designed dial POP. These are therefore provided as standard features of the AccessPath-TS3 system. By offering alternate data paths from each access server to either one or two offload servers, we provide full redundancy for mission-critical data.
Each AccessPath-TS3 system comes with a System Controller that is dedicated to providing console management of each device in the AccessPath-TS3 system cabinet. This feature increases system resiliency by adding a single out-of-band console connection to every AccessPath-TS3 shelf.
Scalability
The AccessPath-TS3 system supports a physical design in which a dual cabinet configuration scales to a maximum hardware density of 84 PRI lines.
Software scalability is provided through use of Cisco IOS software and varies depending on the application. Three orderable options represent the most common applications for which the AccessPath-TS3 system is utilized:
Single-channel terminations (ISDN or modem calls)—Can be terminated in a virtually limitless expansion of cascaded AccessPath-TS3 system cabinets.
Virtual Private Dial Network (VPDN) services—Can be provided by the tunneling of single-channel calls using a virtually limitless expansion of cascaded AccessPath-TS3 system cabinets.
Multichannel ISDN calls—Can be supported for all traffic in a single AccessPath-TS3 system cabinet. Multichannel services are not supported on multiple cabinets preconfigured as a single rotary group.
Compatibility
By integrating access servers, an Ethernet switch, and high-performance routers from a single vendor into one system, the AccessPath-TS3 system avoids incompatibility concerns that normally plague multivendor or multibox installations. The AccessPath-TS3 system is precabled, and individual components are configured with sample (typical) configurations, thereby guaranteeing interoperability.
Integration of Future Hardware
The AccessPath-TS3 system's modular cabinet architecture allows for the rapid implementation of new technologies and hot swapping of new hardware components as they become available.
Functional Overview
T1 or E1 lines, supporting either ISDN PRI or channel-associated signaling (CAS), feed into the AccessPath-TS3 system's Access Server Shelves. Each Access Server Shelf can accommodate four T1 or E1 connections. With a maximum configuration of 21 Access Server Shelves, the AccessPath-TS3 system can accommodate up to 84 T1 or E1 connections. Table 1-1 gives information on the maximum number of calls that can be terminated in an AccessPath-TS3 system.

For example, in a T1 PRI configuration with 21 Access Server Shelves, the AccessPath-TS3 system has a maximum capacity of 1932 analog or single-channel ISDN calls. The maximum configuration of 21 Access Server Shelves provides a maximum capacity of 966 ISDN PRI calls. The calls are aggregated in the Switch Shelf, multiplexed, and sent over a 100BaseT Fast Ethernet connection to the Router Shelf.
Note The switch shelf is optional in AccessPath-TS3 configurations with fewer than
8 Access Server Shelves.
Figure 1-2 illustrates call pathways through the AccessPath-TS3 system.

Figure 1-3 AccessPath-TS3 System Configured for 2 to 7 Access Servers
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 then forwarded to the Router Shelf.
Figure 1-4 illustrates an AccessPath-TS3 system configured for 2 to 11 Access Server Shelves.
Figure 1-4 AccessPath-TS3 System Configured for 2 to 11 Access Servers
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, they are not answered in the Router Shelf, but by the home gateway.
