Esprit 8/16 Channel

Statistical Multiplexer

User Manual

1 INTRODUCTION

The Esprit is an 8 or 16 channel asynchronous statistical multiplexer, which may be
used with Dial up Modems and Leased lines (such as Ki l oStream™) up to 256 Kbps in
the case of the 16 channel unit or 64Kbps for the 8 channel.

The unit is easily configured from ei ther end of the link, using a termi nal or a PC running
a terminal emulation package.

This user manual covers installation and setup of user options for the multiplexer.
A full set of cable specifications are available in the appendices.

Esprit Statmux User Manual December 1997 Issue 1.3 Page 5 of 36

Note: Max rate for 8 channel unit is 64K

1.1 Functional overview

The Es prit has 8 or 16 asynchronous ports, and a single composite link which has a
selectable interface type (X.21, V.24 or V.35) .
The composite interface supports sy nchr onous l i nk r ates of up to 256Kbps (64Kbps for
the 8 channel unit), either dial up or leased line, for connection to Modems or digital
services such as BT KiloStream™.

The sixteen channel unit will support data rates of up to 115.2Kbps, with a maximum
aggregate of 1843.2Kbps.
The ei ght channel unit supports rates up to 38.4Kbps with a maximum aggregate of

307.2Kbps.
Unrestricted speed conversions are also possible by setting different data rates at the

local and remote sites.

Esprit Statmux User Manual December 1997 Issue 1.3 Page 6 of 36

2 USE AND CONFIGURATION

This section covers connection and set-up of the channel data ports. The composite
port is covered in Section 3, the installation section of this manual.

2.1 Data Channel Connection

Peripherals are connected to the V.24/V.28 8-way 'RJ45' type connectors configured
DCE and numbered 1 to 16 (1 to 8) at the r ear of the multiplexe r . The pin connections
for these data channels are defined in Appendix G.

2.2 Default Channel Setup

When delivered, the Esprit Statisti c a l M u l t iplexer i s set to operate with all channels set
as follows:

Rate : 9600 bps
Bits/Char : 8
Stop Bits : 1
Parity : NONE
Flow Control : XOFF
RTS : ON
Mode : NORMAL

2.3 Changing the Configuration

The Es pr it may be configured using an asynchronous terminal. A laptop PC running
an asynchronous terminal emulation prog r am such as PC Anywhere™, CrossTalk™ or
Blast™ is ideal for the field engineer.
Windows™ Terminal may also be used to configure an Esprit but please note that
under Settings - Terminal Preferences, the bo x for 'U se function, arrow and ctrl keys
for Windows' must NOT be set. If it is, then you will not be able to move the cursor
around on the screen.
The te rminal should be connected via its serial port to the SUPERVISOR port on the
rear of the multiplexer.

2.4 Supervisor Terminal requirements

The terminal must be configured to:

8 bit character, no parity, one stop bit, speed 9.6Kbps, Xon/Xoff

A suitable cable for connection of the Supervisor port is defined in Appendix E.

Esprit Statmux User Manual December 1997 Issue 1.3 Page 7 of 36

Please select terminal type from the following:

1 = VT52
2 = VT100
3 = ADDSVP
4 = ADM3A
5 = H1500
6 = N8009
7 = TVI920

2.5 Supervisor Terminal Emulations

Several terminal emulations are supported by the Esprit. When connection is made
between the terminal or PC and the rear panel port labelled SUPERVISOR, the
following screen will appear:

The te rminal type or emulation in use should be selected by pressing the relevant
number key on the PC or terminal. The monitor will now show the basic configuration
screen for the multiplexer setup. This is formatted as below (16 channel unit shown):

Esprit Statmux User Manual December 1997 Issue 1.3 Page 8 of 36

2.6 General Set-Up Display Layout

There are three main areas on the superv isor set-up screen used to change parameters
for the Esprit:

Upper left ­System parameters (Mode,
Link Clock, Carrier, Residual,
and Configure).

Upper right ­Other display pages which
may be selected (Channels 1
to 16, Modem Setup.

Bottom ­Channel configuration.

The initial display is that for the ASYNC channels.

2.7 General Keyboard Conventions

Only a few keys are required to configure the Esprit multiplexer and are summarised
as follows:

 (Right arrow) Moves the cursor to the next field to the right.
 (Left arrow) Moves the cursor to the next field to the left.
 (Up arrow) Moves the cursor to the next field upwards.
 (Down arrow) Moves the cursor to the next field downwards.

+ (Plus) or <SPACEBAR> Toggles the parameter value up to the next available setting.

- (Minus) Toggles the parameter value

down

to the next available setting.
<ENTER> or <RETURN> Accepts the current display page (else same as ).
<CTRL> and U Accepts all changes and causes multiplexer re-configuration.
<ESC> Abandons all changes since last <CTRL> and U.

Esprit Statmux User Manual December 1997 Issue 1.3 Page 9 of 36

2.7.1 Cursor Movement
The cursor symbol ">" is moved around the scr een to the requir ed field using the arrow

keys.

2.7.2 Parameter changing

If it is possible to modify the field over which the cursor is placed, the message "Use
<SPACEBAR>, <+>, <->" is shown at the bottom of the screen. No m essage will
appear if the field is calculated, un-modifiable or hardware set.

Pressing the Space bar, the "+" key or the "-" key will cycle through the choices
available for a parameter.

2.7.3 Accepting all changes and Updating the configuration
If "Control" and "U" are pressed at the same time after the configuration has been

suitably adjusted, the config uration is updated at the local and remote end as necessary
and held in Non-Volatile Memory (NVRAM.)

2.7.4 Abandoning Changes
Pressing ESC at any point before a configuration is updated will cause the message

Abandon Changes? (y/n) to appear at the bottom of the screen. If n is selected the

message will disappear and editing may continue. If y is pres s e d, all modifications will
be abandoned and last updated configuration will be re-painted to the screen.

2.7.5 Local or Remote Configuration.
Most settings are independent at each end of the multiplexer link e.g. Flow Control,

and Rate.

The "Configure" parameter in the upper left of the selected screen shows whether the
LOCAL or REMOTE multiplexer is being configured.

2.7.6 Changing the configuration page

The Configuration Page required, e.g. Channels 1-16, or Modem Setup etc., is
selected by moving the cursor to the upper right area and pressing Enter when
alongside the required page.

2.9 STATMUX channel Configuration

To change the Statmux channel configuration, select the configuration screen (shown
on page 7) by moving the cursor to the top line on the right hand area of the screen,
next to 'Channels 1-16:' (Channels 1-8) and pressing ENTER or RETURN.

The display shows parameters for eight data channels CH1 to CH8, or CH9 to CH16.
The alternative 8 channels are selected by moving the cursor further to the left or right
as necessary.

Each data channel has parameters selectable as detailed on the following page.

2.10 Copying another channel's set-up

Channel data may be copied from another similar STATMUX channel, by placing the
cursor over the channel number field (of the channel to be changed).

The message 'Enter number or use <+>/<-> to copy channel' appears.
Simply entering the number (if channel is less than 10) of the channel to be copied

transfers all of that channels parameter s to the cur rent channel . If the channel number
is greater than 10, the spacebar may be used to increment it through each channel
number.
