Preface
The Syncro 1496 is approved for use in the following countries:
Belgium Luxembourg
Denmark Norway
Finland Portugal
France Spain
Germany Sweden
Holland Switzerland
Ireland United Kingdom
Italy
It is essential that users make themselves familiar with the Appendix
entitled Country-Specific Information, as the appropriate modem for each
country has its own unique setup and connection requirements.
The Syncro 1496 is available in two versions:
Syncro 1496 Standalone modem.
Syncro 1496R Rackmount modem for use in the Network 16 Rack
System.
This manual provides full information for installing, configuring and
using the Syncro 1496 and 1496R (V.32bis) modems.
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 Syncro 1496 and 1496R 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 Syncro 1496 Modem
The Syncro 1496 is a multi-standard autodial modem capable of passing
synchronous data at up to 14400 bps over leased (private wire) lines, and
PSTN (dial-up) lines.
The modem complies with the following ITU-T Recommendations:
V.33 14400 or 12000 bps synchronous operation.
V.32 9600 or 4800 bps synchronous operation.
V.32bis 14400, 12000 or 7200 bps synchronous operation.
V.29 9600, 7200 or 4800 bps synchronous operation.
V.22 1200 bps synchronous operation.
V.22bis 2400 bps synchronous operation.
The other principal features of the modem are:
• Synchronous full- or half-duplex operation over 2-wire leased line or
PSTN.
• Synchronous full-duplex operation over 4-wire leased line.
• Trellis coded modulation for enhanced performance.
• Near and remote end echo cancellation in V.32 and V.32bis modes.
• 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 to V.25 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.
• Comprehensive modem configuration using AT commands, which can
be from a Syncro 1496 or Syncro 1496R modem at a remote site, with
security controls to prevent unauthorised use of this facility.
X450-310851 Issue 2 1-3 Rev.1

• A port conforming to ITU-T V.24/V.28 (EIA RS-232-C) standards for
connecting the DTE.
• 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 test functions to V.54, 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.

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.
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.
X450-310851 Issue 2 1-5 Rev.0

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.
