About This Manual

Welcome to the installation and operation documentation for the Dial Access Switching (DAS) system. The DAS system supports dial-up and dial-backup Frame Relay applications. Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than printed documentation. For more information, see the section, Cisco CD ROM.

This preface contains the following sections:

Objectives

This publication will step you through the initial site preparation, installation, and configuration of the DAS Server Shelf, which is the processor for the Dial Access Switching system, and the Dial-Up Frame Relay application. The DAS Server Shelf works with, and is typically co-located with, a Cisco wide-area switch, such as a Cisco BPX® 8600 series wide-area switch, a Cisco IGX^TM series wide-area switch, or a Cisco IPX® wide-area switch.

Audience

This publication is designed for the person installing the DAS Server Shelf, who should be familiar with electronic circuitry and wiring practices and have experience as an electronic or electromechanical technician. It is also intended for the network administrator who will configure the DAS Server Shelf and the Dial-Up Frame Relay application. The installers and network administrators should also be familiar with Cisco wide-area switches, Frame Relay connections, Cisco StrataView Plus ® network management systems, and Cisco WAN switching networks. During the initial installation of a DAS Server Shelf, it is also helpful to have a system administrator on-hand who is familiar with your network and UNIX servers.

Organization

Chapter 1	Introduction the Dial Access Switching System Provides a brief description of the DAS Server Shelf and the Dial-Up Frame Relay application. It includes examples of dial-up and dial-backup connections.
Chapter 2	Site Requirements Provides information about the electrical power and rack requirements necessary to install a DAS Server Shelf.
Chapter 3	Unpack and Inspect the DAS Server Shelf Provides a description of the DAS Server Shelf shipping container, as well as front- and rear-views of both the AC and DC versions of the DAS Server Shelf.
Chapter 4	Rack Mounting the DAS Server Shelf Provides procedures for installing the DAS Server Shelf in a rack.
Chapter 5	Connecting Power to the DAS Server Shelf Provides procedures for connecting AC or DC power to the DAS Server Shelf.
Chapter 6	DAS Server Shelf Interface Connections Provides procedures for connecting the DAS Server Shelf to the Cisco wide-area switch (PBX, IGX, or IPX switch) and the StrataView Plus Workstation.
Chapter 7	Loading DAS Daemon Software on the StrataView Plus Workstation Provides instructions for loading DAS (INS) daemon software on the StrataView Plus workstation.
Chapter 8	Configuring the Dial-Up Frame Relay Application Provides an overview of the steps that are necessary to configure Dial-Up or Dial-Backup Frame Relay connections, after the DAS Server Shelf is installed and connected.
Chapter 9	Creating a DAS Topology Object with HP OpenView Provides a procedure for creating an DAS object with the HP OpenView Topology tools.
Chapter 10	Understanding the DAS Command Line Interface Provides procedures for using the Dial-Up Frame Relay Command Line Interface (CLI) to view and set parameters on the DAS Server Shelf. The CLI, which is not integrated with StrataView Plus, can be accessed through a remote connection or through a terminal directly connected to the DAS Server Shelf.
Chapter 11	Configuring Automatic Number Identifiers Describes how to use the INS ANI Configuration Interface which is accessed via the StrataView Plus Main Menu, to define parameters for Dial-Up and Dial-Backup calls associated with an Integrated Services Digital Network (ISDN) ANI.
Chapter 12	Configuring Dial-Up Connections Describes how to use the StrataView Plus Connection Manager to configure Dial-Up Connections.
Chapter 13	Configuring Dial-Backup Connections Describes how to use the StrataView Plus Connection Manager to configure Dial-Backup connections. Note that this also involves "associating" a "normal" frame-relay connection with a Dial-Backup connection.
Chapter 14	Dial-Up Frame Relay Operation Provides some quick reference tables for frequently done INS Dial-Up Frame Relay tasks.
Appendix A	Cable Information Provides information about the DAS Server Shelf power cables suppled by Cisco.
Appendix B	Dial-In Support Provides information about attaching a modem to the DAS Server Shelf to allow Cisco StrataCom's Customer Service to dial-in and provide support for Dial-Up Frame Relay.
Appendix C	Troubleshooting Provides some overall troubleshooting hints and a description of some DAS system troubleshooting tools such as the Frame Relay Status Utility, INS Daemon Log, and the INS SNMP Alarms and Traps.
Appendix D	Call Detail Records Provides information about the format and content of the Call Detail Records (CDRs) that are kept for each dial-up and dial-backup call. It also includes information about the DAS-applicable Failure/Error Cause Codes which are included in some CDRs.
Appendix E	Upgrading DAS Server Shelf Software Provides procedures for reinstalling DAS Server Shelf and DAS Daemon software.
Appendix F	Dial-Up Frame Relay Terminology Provides definitions of some terms that have specific meaning for the DAS Server Shelf and the Dial-Up Frame Relay application.

Nonprinting characters, such as passwords, are in angle brackets (< >).
Default responses to system prompts are in square brackets ([ ]).

Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, you must be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the product.

Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss of data.

Note Means reader take note. Notes contain helpful suggestions or references to materials not contained in the manual.

New Features in DAS 1.4

The Dial Access Switching system, the DAS Server Shelf, and the Dial-Up Frame Relay application have been enhanced in DAS Release 1.4 with the following features:

Enhanced call connection performance through parallel processing of connection requests. To achieve maximum performance the user sets up the PRI port manually and leaves it up during Dial-Up Frame Relay operation. (This feature is added by modifying the watchdog.conf file on the StrataView Plus Workstation and wd.config file on the DAS Server Shelf and should be performed only with the advice of Customer Support.)
Call rejection of far-end port failures enables the DAS to reject call requests when far-end ports have failed. With this feature, the DAS rejects call requests to failed far-end ports and transmits a Release message to the ISDN network.
PVC monitoring feature monitors Dial-Up and Dial-Backup calls. If far-end port fails, this feature disconnects the call and sends PVC disconnect and ISDN Release messages. For multiple dormant connections, this feature issues the ISDN Release message only if all the dormant connections are gone, that is, if all the far-end ports failed and PVCs were disconnected.
INS Daemon software operates with both StrataView Plus Release 8.1 and StrataView Plus Release 8.4. A separate binary file is provided for these two versions of the INS Daemon software. See the chapter, "Loading DAS Daemon Software on the StrataView Plus Workstation", for information about loading the separate files.
Combining DAS Server Shelf Installation and Operation publications into a single publication. Previous releases of Dial Access Switching (DAS) Server Shelf and the INS Dial-Up Frame Relay application were documented with separate Installation and Operation publications. With DAS Release 1.4, these two publications have been combined into a single Installation and Operation publication.

In addition, this manual introduces the following product name changes:

The Cisco BPX® 8600 series wide-area switch was previously known simply as the Cisco StrataCom BPX switch.
The Cisco IGX^TM 8400 series wide-area switch was previously known simply as the Cisco StrataCom IGX switch.
The Cisco IPX® wide-area switch was previously known simply as the Cisco StrataCom IPX switch.
The Cisco MGX^TM 8220 edge connector was previously known as the Cisco StrataCom AXIS interface shelf.
