This chapter provides physical and functional overviews of the Cisco AccessPath-TS3 Model 530 Integrated Access System. It contains:
This chapter includes the following sections:
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.
The AccessPath-TS3 system comes in four standard configurations. Each of these configurations include
The following are examples of the different AccessPath-TS3 system configurations.
This configuration uses the dual-wide Ethernet switch port adapter for its primary switching path.
This configuration uses a Catalyst 5002 switch for its primary switching path. It provides redundant switching for increased availability.
The AccessPath-TS3 system supports the following features:
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.
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.
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.
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.
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:
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.
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.
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.
| Connection | Interface | Maximum Number of Calls (21 Access Server Shelves) | Call Type |
|---|---|---|---|
| T1 | PRI | 1932 | Analog or ISDN |
| T1 | CAS a | 1008 | Analog |
| E1 | PRI | 2436 | Analog or ISDN |
| E1 | CAS b | 1344 | Analog |
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.
Figure 1-2 illustrates call pathways through the AccessPath-TS3 system.
Figure 1-3 illustrates an AccessPath-TS3 system configured for 2 to 7 Access Server Shelves.
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.
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.
Figure 1-5 illustrates an AccessPath-TS3 system configured for 2 to 14 Access Servers.

There are bays for up to two AC- or DC-input power supplies. The Router Shelf operates with one power supply. A redundant power supply, which is not required, is shipped with the AccessPath-TS3 system to allow load sharing and increased system availability. The Router Shelf does not support a mixture of AC- and DC-input power.
The Router Shelf provides the following features:
The front of the Router Shelf provides access to an I/O controller and up to six network interface port adapters. (See Figure 1-8.) The I/O controller contains the following:
The Fast Ethernet port provides a 100-Mbps backhaul connection to the network.
The port adapters installed in the Router Shelf support OIR.
Port adapter slots in the Router Shelf are numbered from left to right and from the bottom up, beginning with port adapter slot 1 and continuing through port adapter slot 6. Port adapter slot 0 is the Fast Ethernet port on the I/O controller. (See Figure 1-9.)
The rear of the Router Shelf provides access to the network processing engine and up to two power supplies. (See Figure 1-10.)
