Introduction

Overview of CallVisor ASAI Over the

bbbbbbbb

DEFINITY LAN Gateway

CallVisor ASAI over the DEFINITY LAN Gateway is a communications interface

that provides the functionality of the Adjunct/Switch Application Interface (ASAI)

using an Ethernet transport instead of a Basic Rate Interface (BRI) transport. It

is supported by DEFINITY Communications System Generic 3V4, and by

Generic G3V2 and Generic 3V3 (except for Generic 3VS) after a field

maintenance release has been loaded.

The DEFINITY LAN Gateway system (ED-1E546-70) is composed of the system

assembly and a software application. The system assembly is a Multi-Function

Board (TN2208) and an Alarm Board (TN2170) inserted into a DEFINITY carrier.

The software application serves as an ISDN brouter of ASAI messages through

a TCP ‘‘tunnel’’ via 10BaseT Ethernet.

The ASAI-Ethernet transport option can either replace or supplement BRI. For

example, an ASAI-Ethernet link may replace an ASAI-BRI link if more throughput

is desired for the same client application. Or, the ASAI-Ethernet transport option

may be used in addition to the ASAI-BRI transport option if a client application is

being added to the system and the customer does not want to disturb an existing

client application.

Because the DEFINITY LAN Gateway requires its own administrative information

(not found on DEFINITY), it is necessary to administer the system assembly

(TN2170 and TN2208) as well as the DEFINITY switch. For the system

assembly to work with the LAN, the proper TCP/IP parameters must be set up,

and information about the clients who will use the ASAI-Ethernet service must be

administered on the system assembly.

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Introduction

CallVisor ASAI Over the DEFINITY LAN Gateway is provided with a default set of administered parameters, but customers can also administer the LAN parameters and client information to conform to their networks.

NOTE 1:

AT&T support services for the DEFINITY LAN Gateway system will not troubleshoot a customer LAN. If the customer LAN is experiencing difficulties, customers should follow the escalation path supplied by their LAN provider.

NOTE 2:

DEFINITY switch administration of ASAI does not change when using CallVisor ASAI over the DEFINITY LAN Gateway.

Depending on the system setup desired, customers can configure and administer the DEFINITY LAN Gateway system in several ways:

Using telnet over TCP/IP Using a dumb terminal dedicated to the DEFINITY LAN Gateway circuit

pack Using the RS-232 port of a PC or host attached to the DEFINITY LAN

Gateway circuit pack.

A menu-driven interface offers ease of administration, and help screens are available if assistance is needed. In addition, security features explained in this chapter help guard against unauthorized access.

System Hardware

bbbbbbbbbbbbbbb

The application for the ASAI-Ethernet interface is supported by a system assembly, a ‘‘sandwich’’ of the two boards mentioned previously, the TN2208 (Multi-Function Board) and the TN2170 (Alarm Board). Figure 1-1 shows the DEFINITY LAN Gateway system assembly.

NOTE:

The system assembly is also used to support DEFINITY AUDIX. However, the components are populated differently for DEFINITY LAN Gateway and for DEFINITY AUDIX, so the hardware is not interchangeable. Be careful not to confuse a DEFINITY LAN Gateway system assembly with a DEFINITY AUDIX system assembly when installing or upgrading system software for either product.

bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Introduction

The DEFINITY LAN Gateway system assembly can be distinguished from the DEFINITY AUDIX system assembly by the ‘‘TN’’ codes on the circuit packs and by a DEFINITY LAN Gateway label. The DEFINITY AUDIX system assembly uses TN566 (not shipped on new systems), TN566B, TN567, and TN2169 or TN2170. The DEFINITY LAN Gateway system assembly uses TN2170 and TN2208.

The TN2170 circuit pack supports a hard disk, Ethernet controller, and removable media. It also supports a serial port, an additional analog modem port, and remote maintenance hardware.

The TN2208 circuit pack supports a 32Mhz 486SLC Central Processing Unit (CPU) with 16MB of fixed (non-socketed) memory. It has 2 serial ports and a user interface/Liquid Crystal Display (LCD) panel. Naturally, it also has an interface to DEFINITY call control and switching fabric.

System Software

bbbbbbbbbbbbbbb

The software that provides the DEFINITY LAN Gateway application on the system assembly comes preloaded on the system when it is shipped from the factory. It is also supplied on removable media that can be reinstalled or used to upgrade an existing system.

The function of the software is to act as a mapper (or brouter) for ASAI messages. It links an ISDN network (DEFINITY call control) to a TCP/IP network (computer client) by moving ASAI messages back and forth from Q.921 synchronous data frames to TCP/IP Ethernet packets. It also associates computer clients (by their TCP/IP network addresses) to physical ports on DEFINITY that are administered as ASAI extensions.

This mapping provides a virtual point-to-point connection between a particular computer client and an associated port on DEFINITY. This arrangement continues to support the ASAI ability to sense when a particular computer client connection is lost and send an alarm. It also provides a more secure environment by fixing the addresses of the clients that may receive DEFINITY LAN Gateway service.

Introduction

Upgrading Your Existing System

If you want to have CallVisor ASAI over the DEFINITY LAN Gateway in a

non-supported switch, you must upgrade it with a field maintenance release of

G3V4 software. Contact the Technical Service Center at 1 800 248-1234 for

more information. (You will be prompted for your Social Security Number and

4-digit PIN.)

If you attempt to upgrade from a pre-G3V4 switch, you must remove the

translations (assuming you had the TN2208 circuit pack aliased as a BRI circuit

pack in the pre-G3V4 switch).

WARNING:

If you upgrade your system yourself, follow these precautions: To prevent damage to the DEFINITY LAN Gateway system assembly,

make sure that you have connected the system assembly adapter cables to the port connectors on the back of the switch (see Step 2 in Task 5: Install the DEFINITY LAN Gateway System Assembly in Chapter 2) before you insert the system assembly in the switch carrier.

You can install the system assembly in the switch when the switch is powered on or off. When the assembly is inserted in the slots of the switch carrier, it will automatically power up, run diagnostics, and boot. To avoid a disk crash, never remove the assembly without first completing the shutdown procedure to shut down the DEFINITY LAN Gateway system (and allowing the disk to completely spin down).

For the same reason, do not cycle the power on the switch (for example, during switch acceptance tests) once the system assembly is inserted unless you have first shut down the DEFINITY LAN Gateway system. Refer to the maintenance screens in Chapter 3 for the shutdown procedure.

Security Considerations

Toll fraud is the unauthorized use of a company’s telecommunications system by

an unauthorized third party. DEFINITY LAN Gateway offers the following

security features to help prevent toll fraud and protect against unauthorized users

gaining access to the system and learning the content of calls:

Password protection — The system requires administrators to provide a password before access is granted. Also, when the system is installed, default passwords are changed to help guard against unauthorized access.

Audit trail — DEFINITY LAN Gateway provides selective logging of an audit trail of operations carried across the interface. Users can view a set of Security Logs to learn such information as failed login attempts,

Introduction

unauthorized client access attempts, time of Multi-Function Board resets, and commands executed from Administration/Maintenance screens.

This system does not support an encrypted/secured protocol; therefore, it is possible for a criminal hacker to ‘‘spoof’’ the system by reverse engineering the protocol and then ‘‘impersonating’’ a valid DEFINITY LAN Gateway client. This is more likely to occur if the hacker has physical access to the Ethernet LAN or to a system attached to the Ethernet LAN that supports the DEFINITY LAN Gateway. Customers are encouraged to help protect the system and reduce the possibility of toll fraud occurring by attaching the system assembly and its clients to an isolated, physically secure Ethernet (not connected to any other Ethernet).

Installation

Task 1: Verify the Selected Site

bbbbbbbbbbbbbbb

NOTE:

Defining the system requirements and ensuring that the site meets these requirements are the responsibility of the Project Manager and the customer and must be completed before you install the DEFINITY LAN Gateway system. However, the guidelines are listed here so that you are aware of these requirements.

Verify that the site selected for the DEFINITY switch and the DEFINITY LAN Gateway system provides the following:

A DEFINITY Generic 3V4 switch, or DEFINITY Generic 3V4 software that incorporates a field maintenance upgrade for G3V2/V3.

For a DEFINITY LAN Gateway system being installed in an existing switch, five contiguous slots in a switch carrier to house the DEFINITY LAN Gateway system (slots 16 to 20 in Figure 2-1 that follows). (See Appendix A for carrier worksheets.)

Installation

Humidity range of 20% to 80%, noncondensing. In addition, make sure the site is secure and provides protection from excessive sunlight, heat, cold, chemicals, static electricity, magnetic fields, vibration, and grime.

NOTE:

ASAI must be enabled on the DEFINITY Customer Options form for the system to be fully operational.

Task 2: Gather Required Tools

bbbbbbbbbbbbbbb

To install a DEFINITY LAN Gateway system, you need the following tools:

Narrow width, flat-blade screwdriver 1/4-inch nut driver (recommended) Antistatic grounded wrist strap Punch-down tool

Task 3: Review Safety Considerations

bbbbbbbbbbbbbbb

WARNING:

Electronic equipment can be damaged by electrostatic discharge. Do not touch any electronic component unless you are properly grounded.

DANGER:

Do not touch the switch backplane while installing the DEFINITY LAN Gateway system. The backplane contains dangerous voltages and current.

To prevent damage to the equipment and yourself, adhere to the following:

Make sure you are familiar with the procedures necessary to prevent electrostatic damage to the equipment.

Properly ground a wrist strap. Place the grounded wrist strap on your bare wrist. (The wrist strap must

contact your bare skin directly — do not wear it over your clothes.) Do not remove the system assembly from the polyethylene bag until:

— Your wrist strap is on your wrist and properly grounded. — You have made room in the switch carrier and you are ready to

insert the system assembly in the carrier.

If you need to work on the system assembly — that is, disassemble it — place the assembly on a grounded antistatic work mat.

Installation

Task 4: Verify Components and Connectivity

bbbbbbbbbbbbbbb

Study Figure 2-2 that follows to gain a general understanding of how the system assembly is to be connected. Some customer-furnished LAN equipment is included within the dotted lines in this figure. Helpful definitions for this equipment are as follows.

Balun (balanced/unbalanced) — An impedance matching transformer. Baluns are small, passive devices that convert the impedance of coaxial cable so that its signal can run on twisted-pair wiring. They are used often so that IBM 3270-type terminals, which traditionally require coaxial cable connection to their host computer, can run off twisted-pair. Baluns work for some types of protocols and not for others. There is often some performance degradation with baluns, and the signal cannot run as far on twisted wire as it can on coaxial cable.

10BaseT Hub — An Ethernet LAN that works on twisted pair wiring which looks and feels like telephone cabling. 10BaseT Ethernet LANs work on home runs in which the wire from each workstation snakes directly to the 10BaseT hub (like the wiring of a phone system). The advantages are twofold — first, if one machine crashes, it doesn’t bring down the whole network, and second, 10BaseT hubs often come with sophisicated management software.

The DEFINITY LAN Gateway system installation tasks are the same for all switch types. These tasks include:

Task 5: Install the DEFINITY LAN Gateway system assembly Task 6: Connect the Alarm Board cables Task 7: Install the terminal (optional) Task 8: Connect the Maintenance Modem Task 9: Finalize and test the hardware

Before beginning these tasks, refer to the following worksheets: Appendix A, PBX Carrier Configuration Worksheets

A-1, Port Slot Assignments (Before Carrier Rearrangement) A-2, Port Slot Assignments (For Carrier Rearrangement) A-3, Port Slot Locations for the DEFINITY LAN Gateway System

Assembly

Appendix B, Supported Terminals and Modems/Option Settings

B-1, Terminals/Modems

Task 5: Install the DEFINITY LAN Gateway System Assembly

bbbbbbbbbbbbbbb

This task is required for all installation scenarios.

WARNING:

To prevent damage to the DEFINITY LAN Gateway system assembly, make sure that you (or the factory, for new switches) have connected the system assembly adapter cables to the port connectors on the back of the switch (as described in Step 3) before you insert the system assembly in the switch carrier.

Slot and Carrier Restrictions

If rearrangement of circuit packs in the PBX is required to accommodate the system assembly, rearrange the packs as indicated on Worksheet A-2, Port Slot Assignments, before proceeding.

There is a maximum of one system assembly per Single Carrier Cabinet (SCC) or MultiCarrier Cabinet (MCC). This assembly occupies five slots and should be placed to the far right in the carrier. For thermal reasons, the system assembly should not be placed in MultiCarrier Cabinet C carrier position (top carrier position).

See Appendix A, ‘‘PBX Carrier Configuration Worksheets,’’ for detailed information on the rearrangement of circuit packs and slot restrictions.

DEFINITY LAN Gateway System Slots

The system assembly requires five contiguous port slots in the switch carrier. In this description, the five slots are referred to as the first through the fifth slot, with the understanding that they can be any five contiguous port slots. It is recommended that it be installed as far to the right as possible.

The slots are numbered from left to right on the front panel of the switch cabinet, and from right to left on the rear panel as shown in Figure 2-3, Connecting the Adapter Cables, Rear-Panel View. The five port slots are occupied by the DEFINITY LAN Gateway system assembly as follows:

The first and second slots are covered by the DEFINITY LAN Gateway disk and removable media and are not connected to the switch backplane or amphenol connectors.

The third slot is connected to the Alarm Board (ALB). The fourth slot is connected to the Multi-Function Board. The fifth slot remains vacant to provide added clearance and cooling for

certain components on the Multi-Function Board.

If the DEFINITY LAN Gateway system was shipped in a new switch, skip to Step 7 of this task.

Installation Steps

Using Worksheet A-3, Port Slot Locations for the DEFINITY LAN Gateway System Assembly, follow the steps below to install the system assembly.

1. Remove any existing cables from the third and fourth slots of the five contiguous slots reserved for the DEFINITY LAN Gateway system. For example, if you are to install the DEFINITY LAN Gateway system in slots 7 through 11 of carrier A in the switch, remove the I/O cables from slots 8 and 9. (These are the two slots that provide connectivity to the DEFINITY LAN Gateway system circuit packs.)

2. Referring back to Figure 2-3 and to Steps 2a and 2b that follow, connect the DEFINITY LAN Gateway system assembly adapter cables to the port connectors on the back of the switch.

Installation

NOTE:

You must connect these adapter cables directly to the port connectors on the switch. If you install another cable between the switch and the cables, the DEFINITY LAN Gateway system will not operate correctly (either now or in the future).

a. Attach the male D-type amphenol connector on the Alarm Board

(ALB) cable (the one with two amphenol connectors, one RJ45 LAN connector, and one 25-pin RS-232 connector) to the ALB (TN2170), the third slot of the five DEFINITY LAN Gateway system slots.

b. Attach the male D-type amphenol connector on the Multi-Function

Board (MFB) Y-cable (the one with one amphenol and two RS-232 connectors) to the MFB (TN2208), the fourth slot of the five DEFINITY LAN Gateway system slots.

NOTE:

If you are installing the DEFINITY LAN Gateway system in a DC-powered switch, perform the following steps to install the 116A isolating data interface. Otherwise, skip to Step 4.

3. Install the 116A isolating data interface. a. Attach the male end of a null modem (supplied with the DEFINITY

LAN Gateway system PEC) to the RS-232C connector on both PORT A and PORT B on the MFB Y-cable. Attach the male connector of the 116A to the other end of the null modem.

b. Attach the male end of another null modem to the RS-232

connector labeled RESERVED on the ALB Y-cable. Attach the male connector of the second 116A to the other end of the null modem.

4. Insert the system assembly (see Figure 2-4, DEFINITY LAN Gateway

System Assembly) into the switch cabinet as follows: Holding the system assembly by the outside edges of the faceplate, line

up the Alarm Board and the Multi-Function Board with the bottom guides of the third and fourth slots, respectively, of the five reserved port slots in the switch carrier.

WARNING:

The DEFINITY LAN Gateway system will automatically boot when seated in the slots. Damage to the disk could occur if the assembly is removed while booting. Therefore, try to avoid the need to adjust or reinsert the assembly after the first attempt to insert it; make sure that the assembly is properly aligned in the slot, and then insert it with a single firm push.
