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 KiloStream™) up to 256 Kbps in
the case of the 16 channel unit or 64Kbps for the 8 channel.
The unit is easily configured from either end of the link, using a terminal 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 Esprit 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 synchronous link rates 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 eight 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 rear of the multiplexer. The pin connections
for these data channels are defined in Appendix G.
2.2 Default Channel Setup
When delivered, the Esprit Statistical Multiplexer is 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 Esprit may be configured using an asynchronous terminal. A laptop PC running
an asynchronous terminal emulation program such as PCAnywhere™, 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 box for 'Use 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 terminal 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 terminal 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):

2.6 General Set-Up Display Layout
There arethree main areas on the supervisorset-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:
(Ri
g
ht arrow) Moves the cursor to the next field to the ri
g
ht.
(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> To

2.7.1 Cursor Movement
The cursor symbol ">" is moved around the screen to the required 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 message 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
suitablyadjusted, the configuration is updated at the localand 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 nis selected the
message will disappear and editing may continue. If yis pressed, 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.
