1. Introduction

_ ______________________________________________________________________________________

AUDIX Networking enables an organization to transmit messages between two or more AUDIX systems, making the group of systems appear as one large system. One-Cabinet AUDIX systems, Two-Cabinet AUDIX systems, and AUDIX Large systems can be used. These systems can be located on the same site or spread out over several locations in the same or different cities. A single network can have up to 101 systems (a local system can be connected to up to 100 remote systems).

When considering adding more than one system to a single switch, keep in mind that although several systems can be networked at a single location, the systems may or may not be able to be installed as fully integrated AUDIX systems (that is, with a data link installed between the AUDIX system and the switch). The number of directly connected AUDIX adjuncts depends on the switch:

• System 75 and DEFINITY Communications System Generic 1, Generic 3i, and Generic 3s support one

directly connected AUDIX system.

• System 85 R2V2 and R2V3 support up to four AUDIX adjuncts.

• System 85 R2V4 and DEFINITY Generic 2 and Generic 3r support up to eight AUDIX adjuncts.

Any additional AUDIX systems must be installed as stand-alone systems.

THE NETWORK INTERFACE

An AUDIX system provides three types of network connections, using either the Electronic Industries Association (EIA) RS-232 protocol or AT&T’s DCP. They are:

• Dedicated RS-232: AUDIX systems communicate through direct cabling. No connection to the switch

is required. Communication between AUDIX systems is straight RS-232. Any channel connected in this manner cannot be shared with other adjuncts or with other AUDIX system applications. This connection requires AUDIX R1V5 or later software and a TN539 or TN539B ACCE circuit pack.

• Switched RS-232: AUDIX systems communicate through dial-up modems. Communication between

systems is via analog facilities. Channels connected in this manner can be shared with other systems or with the AUDIX Call Detail Recording Package (CDR). This connection requires AUDIX R1V5 or later software and a TN539 or TN539B ACCE circuit pack.

Special Application: The RS-232 channels can be converted to DCP before entering the switch. This is done with a data module instead of the modem. This, too, is a dial-up connection; all six AUDIX network channels appear at the switch as DCP channels.

1-1

1-2 Introduction

________________________________________________________________________________________________

Although a total of six network channels are available on an AUDIX system, the AUDIX

NOTE

R1V3, R1V4, and R1V5 software limit the number of simultaneously active channels to four. To use all six channels simultaneously, an AUDIX system must have R1V6 or later software and a vintage 7 TN539 or a TN539B ACCE.

• Switched DCP: AUDIX systems communicate through dial-up DCP connections at the switch.

Communication between systems can be via digital or analog facilities. DCP modes 1, 2, and 3 are supported. Channels connected in this manner can be shared with other systems for networking and for other AUDIX system applications. This connection requires AUDIX R1V3 or later software and an ACC (TN366 or TN366B) or ACCE (TN539 or TN539B) circuit pack.

If the customer’s switch does not support the DCP interface, an AT&T DCP switch can

NOTE

The TN539 or TN539B ACCE circuit pack provides two RS-232 channels and four DCP channels. Both types are two-way communications links. The type or types of connections used depend on the location and number of AUDIX systems involved, the type of switch(es) involved, networking facilities, and whether or not the customer wants to use the Text Services Interface and/or Call Detail Recording applications.

be used to provide this interface. For local networking, this is usually done with a MERLIN II Communications System. (Remote networking with MERLIN II is not supported.)

LOCAL NETWORKING

In a local network setup, one or more AUDIX systems work with a single switch. The local system can be networked with up to 100 other remote AUDIX adjuncts. In this setup, the local system is the one to which the administration terminal the system administrator is using is connected; all other systems are considered remote. All AUDIX subscribers can be assigned the same (or no) preﬁxes and separate extension numbers, or different preﬁxes to distinguish among local systems.

A one-cabinet 16-port AUDIX system can provide services to up to 2000 local subscribers; a two-cabinet 32-port system can handle twice as many. When AUDIX systems are integrated into a local network, they take on the appearance of one large AUDIX system. The AUDIX systems can reside together in the same equipment room with the switch, or in different locations according to the type of connections made.

_ ______________________________________________________________________________________

Introduction 1-3

REMOTE NETWORKING

In a remote network, AUDIX systems are integrated with more than one switch. The local system can be networked with up to 100 other remote AUDIX adjuncts. The local system is the one to which the administration terminal the system administrator is using is connected; all other systems are considered remote. These remote systems may be geographically distant, have different dial plans, and use different connections such as:

• Digital Service (DS1) facilities between switches

• Voice-grade (analog) facilities between switches

Any remote network can be mixed with a local network. Switches can use any public or private switched networking facility, or be a part of a Digital Communications System (DCS) network.

NETWORK PLANNING

Planning is an essential ﬁrst step in setting up an AUDIX network. Network administration should not be started until the local AUDIX system is running smoothly. Network planning should begin as soon as the customer decides to network their AUDIX systems.

One person (perhaps someone also serving as the administrator of one of the AUDIX machines in the network) must serve as coordinator of the network. The network coordinator must establish and maintain a good line of communication with each of the remote system administrators in order to facilitate necessary cooperation and ﬂow of information. Because every AUDIX machine within the network must be administered with information about any other AUDIX machine with which it will be exchanging messages, the network coordinator must be prepared to supply each local AUDIX system administrator with the information.

AUDIX NETWORK IMPLEMENTATION

Each AUDIX system in the network requires the following. Each item is explained in some detail on the following pages:

• Speciﬁc releases of software.

• AUDIX Communications Controller (ACC) or AUDIX Communications Controller Enhanced (ACCE)

circuit pack.

• Speciﬁc issues of supporting circuit packs.

• Rear connector panel and backplane modiﬁcations.

• New network cabling used with most types of networks. When unique cabling and equipment are

required, they will be pointed out in chapters 2 through 7.

• AUDIX system translations must be added.

1-4 Introduction

________________________________________________________________________________________________

AUDIX Software

An AUDIX network can consist of a mixture of R1V3, R1V4, R1V5, R1V6, and R1V7 systems. If desired, you may upgrade your AUDIX-L to R1V5 or upgrade your AUDIX one- or two-cabinet system to the latest software version. See the System Description manual (585-305-201) for ordering codes.

If the network contains R1V3 or R1V4 systems, the Sending Restrictions feature cannot be

NOTE

used.

ACC/ACCE

The AUDIX Communications Controller (ACC) or AUDIX Communications Controller Enhanced (ACCE) is the circuit pack that provides the interconnections for AUDIX networking. It must be installed in slot 03 of a one- or two-cabinet AUDIX system and in slot 16 of an AUDIX Large Data Base Processor (DBP) carrier (J58888K).

This section describes the ACC or ACCE circuit packs currently in existence. All new AUDIX systems ordered with networking are shipped with the latest circuit pack available, currently the TN539B AUDIX Communications Controller Enhanced (ACCE). However, a new AUDIX system can be added to an existing network where the earlier TN366, TN366B, or TN539 circuit packs are used.

TN366 ACC

This circuit pack provides four DCP channels. It must be a TN366 vintage 5 or later. This circuit pack is no longer orderable, but if the customer has an older vintage and wishes to upgrade, this circuit pack is available through QPPCN 330DR (comcode 103279840). It will work with R1V3 and later software.

TN366B ACC

This circuit pack provides four DCP channels. It will work with R1V3 or later software. This circuit pack is no longer orderable (comcode 106186588).

The TN366B is a TN366 that has been enhanced for the following reasons:

• The TN366B will work with modem pools that use 7400A DSUs; the original TN366 will not.

• The TN366B will work with the MERLIN II Communications System which is used as a DCP interface

for non-DCP switches; the TN366 will not.

• When a Generic 2 universal module serves as the host switch, the TN366B allows access to all four

DCP channels; the TN366 does not.

_ ______________________________________________________________________________________

Introduction 1-5

TN539 ACCE

This circuit pack provides four DCP channels and two RS-232 channels. It will work with R1V5 and later software. The Vintage 7 TN539 permits six simultaneously active ports. Vintage 4 and earlier of the TN539 permits four simultaneously active ports. This circuit pack is no longer orderable (comcode

103281473). It provides all the functionality of the TN366 or TN366B with the following additions:

• Multi-stage dialing

• DCP Mode 1 (56 Kbps) interface

• RS-232 interface

Customers who implemented 56 Kbps networking using TN539 ACCE boards may wish to

NOTE

TN539B ACCE

This pack replaces the TN366, TN366B, or TN539 circuit pack (comcode 106757768). It provides all the functionality of the previous networking boards as well as 56 and 64 Kbps loopback testing capabilities.

upgrade to the TN539B ACCE in order to take advantage of the performance improvements and loop-around testing capabilities offered on this board by R1V7 software.

All new systems ship with a TN539B ACCE. In addition, you may wish to upgrade an earlier board to a TN539B ACCE for the following reasons:

• You have a TN366 or TN366B ACC and you wish to use the two RS-232 ports available on the

TN539B.

• You have a TN366 or TN366B ACC and you wish to obtain the additional activity status

information available on the maintenance : network form in R1V7 (for example, if you are using the R1V7 network turnaround feature).

• You have a TN366 or TN366B ACC or a TN539 ACCE and you wish to upgrade to a TN539B ACCE

for performance reasons. A TN539B is required at both the sending and receiving machine in order to achieve increased performance.

• You have a TN539 ACCE running DCP Mode 1 (56 Kbps) connections and you wish to replace it with

the TN539B in order to take advantage of the AUDIX R1V7 loop-around testing capabilities and possible performance improvements (see the previous item).

All TN539B ACCE orders (new or upgrade) include two H600-330, Group 1 null-modem adapters and one H600-331, Group 2 cable. See the System Description manual (585-305-201) for ordering codes.

1-6 Introduction

________________________________________________________________________________________________

Other AUDIX Circuit Pack Requirements

Certain circuit packs must be present and certain other packs must be of a speciﬁc vintage or issue.

One-Cabinet and Two-Cabinet AUDIX System

In slot 01 of the base cabinet the AUDIX system must have the following:

• TN506B circuit pack (comcode 105222301).

In slot 04 of the base cabinet the AUDIX system must have the following:

• TN472C vintage 2 (white wire 10-17) or later circuit pack (comcode 105474126).

This is the Data Base Processor Central Processing Unit (DBP-CPU).

In slot 06 of the base cabinet the AUDIX system must have the following:

• UN160B vintage 2 or later circuit pack (comcode 105319818). This is the Data Base Processor

Interface (DBPI).

AUDIX Large System

In slot 01 of the DBP carrier (J58888K) the AUDIX system must have the following:

• TN506B circuit pack (comcode 105222301).

In slots 04-07 and 12-14 of the DBP carrier the AUDIX system must have the following:

• TN508 (vintage 4 or higher); up to seven packs.

In slot 08 of the DBP carrier the AUDIX system must have the following:

• TN509C circuit pack (comcode 105319286). This circuit pack is available through QPPCN 444DR.

In slot 10 of the control carrier (J58888H) the AUDIX system must have the following:

• UN160B circuit pack (comcode 105319818).

In slot 08 of the power carrier (J58888L) the AUDIX system must have the following:

• 495JB power converter (comcode 104016746).

Rear Connector Panel and Backplane

The network cabling requires a connector on the back of the AUDIX system cabinet. This connector must be attached to the backplane. Certain versions of the backplane require wire modiﬁcation.

_ ______________________________________________________________________________________

Introduction 1-7

One-Cabinet and Two-Cabinet AUDIX System

For new orders, an ACC/ACCE port will be installed at the back of the AUDIX system base cabinet and wired to the backplane.

For upgrades to existing systems, check the base cabinet for an ACC D05 connector. This is a 50-pin Amphenol connector. Order the AUDIX Networking upgrade kit D181965 if this port is missing (comcode

845953108).

Rear Connector Panel and Backplane (Large)

Check the control cabinet for an ACC D06 connector. This is a 50-pin Amphenol connector.

• If the connector is missing, order the AUDIX Large Networking Upgrade kits D181757 (comcode

105308696) and D182422 (comcode 845798131).

• If the port is installed, check the label on the cable that goes from the connector to the backplane. It

will probably be an ED-1E434-11, Group 373 cable. If the system is to use EIA RS-232 ports for its network, this cable must be replaced with a Group 374 cable — order the AUDIX Large Networking

Upgrade kit D182422.

Network Cabling Common to Most Conﬁgurations

New AUDIX systems ordered with networking will be shipped two H600-330, Group 1 null-modem adapter cables for the RS-232 ports (see Figure 1-1, H600-330, Group 1 Special AUDIX Null-Modem

Cable) and one H600-331, Group 2 breakout cable (see Figure 1-2, H600-331, Group 2 AUDIX Networking Breakout Cable).

Systems that already have networking installed may have the H600-331, Group 1 networking breakout cable rather than the H600-331, Group 2 cable (see Figure 1-3, H600-331, Group 1 AUDIX Networking Breakout Cable). However, the Group 1 cables are no longer shipped.

H600-330, Group 1 Cable

The special null-modem adapter cables are used only for dedicated RS-232 connections. Two are supplied (one for each RS-232 port).

The null-modems are unique; do not substitute standard null-modems in this application.

All new AUDIX networking systems are shipped with one H600-331, Group 2 breakout cable. One end of the Group 2 cable is a 50-pin male Amphenol connector that connects to the ACCE on the AUDIX system. The other end of the cable has a 50-pin female Amphenol connector and two 25-pin RS-232 male connectors. See Table 1-1 for the pin assignments.

The female Amphenol connector provides access to the four DCP channels (AUDIX networking channels 1, 2, 3, and 4). The RS-232 connector A provides access to one RS-232 channel (AUDIX networking channel 5), and RS-232 connector B provides access to the other RS-232 channel (AUDIX networking channel 6).

H600-331, Group 1 Cable

The H600-331, Group 1 breakout cable is no longer shipped; only an AUDIX system that is already installed will have the Group 1 networking cable. One end of this cable is a 50-pin male Amphenol connector that connects to the ACC or ACCE on the AUDIX system. The other end of the cable has two 8-pin DCP connectors and two 25-pin RS-232 male connectors. See Table 1-2 for pin assignments.

The H600-331, Group 1 DCP connector 0 provides access to two DCP channels (AUDIX networking channels 1 and 2). DCP connector 1 also provides access to two DCP channels (AUDIX networking channels 3 and 4). The two 451A adapters are shipped on the ends of connectors 0 and 1. The D8W-87 extension cords and 103A adapters must be ordered separately.

The H600-331, Group 1 RS-232 connector A also provides access to one RS-232 channel (AUDIX networking channel 5), and RS-232 connector B provides access to another RS-232 channel (AUDIX networking channel 6).
