Preface

The Mayze 24 is available in two versions:

Mayze 24 Standalone modem.

Mayze 24R Rackmount modem for use in the Network

16 Rack System.

This manual provides full information for installing,

configuring and using the Mayze 24 and Mayze 24R

modems as supplied for use in the United Kingdom.

PART 1 of the manual has been laid out in a sequence that

will allow you rapidly to become familiar with the essential

features of the modem and to get it operational for

straightforward use on the PSTN.

PART 2 takes you step-by-step through the many features

of the modem that allow it to carry out complex tasks in a

variety of environments.

Throughout this manual the Mayze 24 and Mayze 24R are

described as 'the modem' where features are common to

both. Where necessary they are differentiated by

'standalone' or 'rackmount' respectively.

The Network 16 Rack System which houses the rackmount

version is referred to as 'the rack system', and the Network

16 Controller Card is referred to as 'the controller card'.

Both these items are described in separate manuals.

1 Introduction

1.1 The Mayze 24 Modem

The Mayze 24 is a quad-standard autodial modem capable of passing

asynchronous data at up to 19,200 bps, and synchronous data at up to 2400

bps. It can operate over PSTN (dial-up) or leased (private wire) lines.

The modem complies with the following ITU-T Recommendations:

V.22bis 2400 synchronous or asynchronous operation.

V.22 1200 or 600 bps synchronous or asynchronous

operation.

V.23 1200/75, 75/1200 bps full-duplex or 1200/1200 half-

duplex asynchronous operation.

V.21 300 bps asynchronous operation.

The other principal features of the modem are:

• Automatic dialling using AT or V.25bis commands.

• An electronic storage system for telephone numbers. Numbers are

stored, and subsequently retrieved, by using the numbered buttons on

the front panel, or by AT commands.

• Automatic answering of incoming calls. Disconnection of calls is always

completed 'cleanly' so that the modem is ready for the next call.

• Storage of up to 16 pre-set configurations.

• The modem supports V.42 error correction and V.42bis data

compression, giving an asynchronous throughput of up to 19,200 bps.

For compatibility with other modems, error correction and data

compression conforming to the MNP (Classes 1 to 5) de-facto standard

are also supported.

• Comprehensive modem configuration using AT commands, which can

be from a Mayze 24 modem at a remote site, with security controls to

prevent unauthorised use of this facility.

• A port conforming to ITU-T V.24/V.28 (EIA RS-232-C) standards for

connecting the DTE.

X460-306851 Issue 1 1-3 Rev.1

• A separate command port for connection to a terminal or PC, so that

commands may be entered or calls monitored while the modem is in use.

• Comprehensive V.54 test functions initiated by AT command, or by

front panel switches.

• Modem Management. The modem may be controlled by the Network 16

Controller Card or Network 6, and managed as part of a network using a

high-level network management system.

MAYZE 24

1.2.1 The Indicators

The indicators are on the front panel of the modem, which is shown in

Figure 1-1.

RUN A continuous light means that power is on and the modem is

functioning correctly. A flashing red light indicates that a

test is being performed.

TXD Transmit Data. A flashing light indicates that data is being

transferred from the local DTE.

RXD Receive Data. A flashing light indicates that the modem is

sending data to the local DTE.

RTS Request To Send. A continuous light indicates that the local

DTE is ready to send data. In full-duplex mode this is

normally lit at all times, but in half-duplex mode, only when

data is ready to be transmitted.

CTS Clear To Send. A continuous light indicates that the modem

is ready to transmit data to a remote modem. In full-duplex

mode this is normally lit at all times, but in half-duplex

mode, lights shortly after the RTS indicator.

DCD Data Carrier Detect. Lit to indicate recognition of a carrier

signal from the remote modem. In full-duplex mode this is

normally lit at all times, but in half-duplex mode, only when

the remote modem has control for transmitting.

X460-306851 Issue 1 1-5 Rev.0

DSR Data Set Ready. Lit to indicate that the modem has control

of the line and is in data transmit mode. During a self-test

with signal injection, indicates errors.

DTR Data Terminal Ready. Lit to indicate that the local DTE is

ready to begin communications.

OH Off Hook. Lit when the modem has connected to the

telephone line.

1.2.2 The Controls

The controls are on the front of the modem, which is shown in Figure 1-1.

The names above the line are for on-line operation of the modem. The

names below the line are for configuration loading, or dialling on the

PSTN. The left-hand button is a non-latching switch. The other five have

a latching action.

a

DATA Use as DATA to go into data mode when manually

ENTER connecting a call, and press again to revert to

command mode.

Use as ENTER to load a configuration or dial a

telephone number.

ANS Use as ANS to cause the modem to go into answer

4mode; release the button to put the modem into

originate mode. (Note that when your modem

answers a call it will default to answer mode,

irrespective of the state of this button.)

Use as 4 in conjunction with the DIAL, 2and 1buttons

to select a configuration or telephone number.

TEST Use as TEST to activate a test sequence for local

2or remote tests with your modem.

Use as 2in conjunction with the DIAL, 4and 1buttons

to select a configuration or telephone number.

AL Use as AL to select an analogue loopback.

1Use as 1in conjunction with the DIAL, 4and 2buttons

to select a configuration or telephone number.

RDL Use as RDL to select a remote digital loopback.

LOAD Use as LOAD to select a load configuration option.

X460-306851 Issue 1 1-6 Rev.0

a

FB Use as FB to revert to the selected fallback speed.

DIAL Use as DIAL to select a stored telephone number to

dial.

It is also used in conjunction with the 4, 2and 1

buttons to load a factory or user configuration.

More-detailed descriptions of the uses of the buttons are given in the

descriptions of the functions for which they are needed.

1.2.3 The Connections

The connections are made from the rear panel of the modem. The 230 volt

version is shown in Figure 1-2.

Pin assignments and suggested cable configurations are detailed in

is not used, then the modem must be earthed

through the mains cable, which must be plugged in

POWER 2-metre mains cable fitted with a moulded plug for

connection to a standard power outlet. To isolate the

modem from the power source, first remove the line

cord, then remove the mains plug from the power

outlet.

X460-306851 Issue 1 1-7 Rev.1

first disconnect the modem from the line and then

from the power supply before replacing this fuse.

Always replace the fuse with one of the same rating.

SWITCH Modem power ON (1) or OFF (0).

LINE 3-metre 4-way line cord fitted with a standard British

Telecom plug to connect to the dial-up network.

PHONE Socket for a telephone handset. A telephone

connected to this socket may be used to manually dial

calls. For safety a blanking plug is fitted in this socket

before shipping. The Appendix entitled 'Technical

Guide' contains instructions for removing the

blanking plug. See also the Appendix entitled

'Country-Specific Information'.
