Installation Guide

This chapter describes the ProntoNet hardware and user installation.

The installation and servicing instructions in this manual are for use by qualified personal.

II.1 Initial checks

Before unpacking unit check its packaging for any signs of damage or
mishandling during transportation, report any damage to the shipping company
immediately. Unpack the unit carefully, if you find any damage or the unit does
not work correctly, you should contact Prodys or its distributor as soon as
possible.

II.2 Installation

The ProntoNet is designed to be housed in a standard 19” rack. The unit is

44.45mm high (1U, or 1.75 inches). When choosing a suitable place for
installation, please bear the following in mind:

 The position must allow for easy connection of cables to the back of

the unit.

 The front panel must also be accessible, both for connections and to

be able to see the Display, keyboard and LED indicators.

 The air vents must not be obstructed
 We do not recommended that the unit is mounted directly above

other equipment, especially ones that generate a lot of heat.

II.3 The rear panel

The majority of the connections of the ProntoNet are found on the back panel.
They are grouped together according to their function, as below:

II.3.1 Power

On the back panel you will find the main power inlet. You will also find the main
power switch and the fuse holder. The ProntoNet unit is designed to take AC
universal power, from 100 to 240 VAC with frequency between 50Hz and 60Hz.

You will also find a fuse holder that holds two fuses, one for each phase of input.
When it is necessary to replace either fuse, it is important to make sure that it
complies with the technical specifications outlined below that will ensure
adequate protection.

Fuse requirements:
Fuse type: Type T

Amps 2A
Power 250V

ATTENTION – CHANGING THE FUSE

Disconnect the power cable BEFORE changing the fuse.

24 VDC SECONDARY POWER SOURCE

 THIS IS OPTIONAL AND DOES NOT COME FITTED AS STANDARD.

 The unit will switch automatically from the primary power source to the

back-up power source in the event of a cut in the primary power supply.

II.3.2 Communication Interfaces

The ProntoNet is equipped with three different communication interfaces –
Ethernet, ISDN and X21. These are all accessed on the rear panel, as shown in
the following diagram:

ISDN

Prontonet User’s Manual v410 10

LAN Ethernet X21

II.3.2.1. Ethernet port – the LAN Connector

The LAN socket is an standard 100Base-Tx (10/100 Mbps) Ethernet connection
that takes the typical RJ45 plug. Through this Ethernet port it is possible to
transmit and receive audio, as well as manage the equipment. Next to the
socket there are three LEDs that indicate different states for the connection and
these are very useful in problem-solving situations.
LAN LED’s:

 Connection to a Hub or Switch

In the majority of cases you can simply connect the unit’s LAN port to your
Ethernet network’s Hub or Switch using an Ethernet cable (CAT5). In this
case you should use a standard ‘straight-through’ Ethernet cable (not a
‘cross-over’ cable). This kind of cable can normally be found in any IT shop.
In any case, this cable is described in more detail below:

 Connection to a PC

In some cases, such as when you configure the equipment, it is possible
that you will want to connect the unit directly to a PC. In this case the PC
must have a free Ethernet port to connect to and you must use a ‘cross­over’ Ethernet cable. Again, any good IT shop will stock these cables. This
time the wiring is as follows:

Prontonet User’s Manual v410 11

II.3.2.2. ISDN Port

The ProntoNet incorporates an ISDN terminal adapter that allows connection to
a basic ISDN line (2B+D). It supports different ISDN protocols (EURO_ISDN,
DMS100, AT&T 5ESS and NAT1). To connect there are two RJ45 connectors: one
for connecting to an S/T interface and the other for connecting to a U interface.

 The U connector is only available if an NT1 interface is installed.

 The NT1 interface is optional and is not supplied as standard.

When the ProntoNet is connected to a basic rate interface with bus configuration
and the unit is the termination point, it must be loaded with 100 Ohm resistors.
These may be already fitted in the connection socket, if you do not have external
termination, the ProntoNet has jumpers available internally that can be set to
terminate the ISDN line. The jumpers are found next to the RJ45 connectors.

100Ω RESISTORS CONNECTED

Prontonet User’s Manual v410 12

II.3.2.3. X21 Port

The X21 Port allows the transmission and reception of audio via a dedicated
digital connection. The socket is the standard 15-pin X21 subD with the
following connections:

Prontonet User’s Manual v410 13

II.3.3 RS 232 Ports

There are two RS232 ports for use as auxiliary data ports. These ports allow the
transmission and reception of data along with encoded audio. Port A is always
ready. Port B is only available if the ProntoNet is configured as a DUAL Codec,
therefore able to operate two totally independent communication channels. Note
that these sockets are RJ45 connections, as opposed to the typical 9-pin subD
connections. To make the conversion between RJ45 and RS232 there are
modular connectors available that should be wired as follows:

9-pin female

D-sub

Connector

The ports are always set to 8 DATA bits, NO parity, 1 START bit and 1 STOP bit.
The bit rate can be adjusted to between 300 and 9600 bps via software.

The ProntoNet acts as a DCE device, therefore the connection to each of the
RS232 ports is wired in the following way:

ProntoNet – Pin 7 connector RJ45.........................Pin 2 PC

ProntoNet – Pin 2 connector RJ45.........................Pin 3 PC

ProntoNet – Pin 3,6 connector RJ45......................Pin 5 PC

The ProntoNet ignores hardware handshaking signals.

connection. Note that the keys have different functions depending on the
communication line status at any given moment. Additionally, the display will
also show different information depending on the type of NET selected - IP,
ISDN or X21.
Depending on the line’s status, CALL 1 and CALL 2 will function in the following
way:

 With the line disconnected:

a) Initiation of a communication

access the call initiation menu. Depending on the type of NET
selected (IP, ISDN or X21) the dialog that you will see will vary.
(Note that, CALL 2 only works when ISDN is selected as the
NET).

b) Connecting to an incoming call

to manual answering, the CALL 1 or CALL 2 keys will connect the
line when an incoming call is detected on the respective lines.

 With a line connected: There are two distinct functions:

a) A short press

the current connection.

b) A long press

will display on-screen the number or IP address of

(over 1 second) will disconnect the associated line.

: Pressing CALL 1 or CALL 2 will

: if the ProntoNet is pre-configured

It is posible to program a number of call retries from the ProntoNet web page.

III.2.1.1. Establishing a call when ProntoNet is configured as an IP codec

(NET = IP)

If an IP network is selected, pressing CALL 1 will display the following:

The user must select beforehand if the IP communication type is MULTICAST
mode (point to multi-point) or UNICAST mode (point to point). Next, depending
on the selected option will show:

 CALL2 key is available from version 3.3.1 in order to establish a second unicast

TX communication, sending the same audio as in line 1.

Prontonet User’s Manual v410 23

III.2.1.2. Establishing a call when ProntoNet is configured as an ISDN codec

(NET = ISDN)

Pressing the CALL 1 key will display the page where you can enter the number to
be called on Line 1. The CALL 2 key does the same for Line 2.

III.2.1.3. Establishing a call when ProntoNet is configured as an X21 codec

(NET = X21)

ISDN L1 DIAL

When ProntoNet is set up for dedicated lines (NET = X21) it is not necessary to
talk about establishing connections in the same way as we have been doing with
IP networks and ISDN. In reality, the CALL 1 key simply enables or disables
communication via the X21 port. The CALL 2 key does nothing as there is only
one X21 port available.

To connect the Line in X21 press CALL1. To disconnect the line press
CALL1 over 1 second.

Each Key has an associated LED that indicates the following situations:

LED off: Line disconnected

LED on: Line connected

LED blinking: Call in progress or incoming call detected

III.2.2 The INF key

This key allows the user a simple and quick way to display detailed information
on the status and configuration of the ProntoNet. Given that the screen is not
able to display all the information at once, you can cycle through the different
information screens by repeatedly pressing the INF button. These screens are:

1. Audio input VU meters.

2. Audio output VU meters.

3. Decoding algorithm.

4. Encoding algorithm.

5. IP configuration parameters.

6. General configuration: NET type selected (IP, ISDN o X21), audio
input, etc.

7. GPIO status.

Looking at each one in detail.

III.2.2.1. Screen 1: Audio input VU meters

The audio input levels are represented on-screen horizontally over 18 characters.
Each character represents 3dB. All characters showing will represent 0 dBFs.
When only one character is showing it therefore represents a value between –96
and –56 dBFs. From version 3.3.1 on, the dBFs value is indicated.

L:>>>>>>

R:>>>>>

III.2.2.2. Screen 2: Audio output VU meters

From version 3.3.1, the audio output vu meters can be monitored from
the front panel display, in the same manner as with the input vu
meters.

Prontonet User’s Manual v410 25

III.2.2.3. Screen 3: Decoding algorithm

This window shows the algorithm that is selected and synchronised for Decoder
1 and 2 (number 2 is only relevant when ProntoNet is working as a DUAL codec).
Here are some examples:

.

If the Decoder is not synchronised it will show the text “SEARCHING”

The different algorithms are written in the following way:

 PCM – Mode - Fs – number of bits.
 G711 – Law.
 G722.
 MPEG Layer II – Bit rate – Mode – Fs – CRC.
 MPEG Layer III – Bit rate – Mode – Fs – CRC.
 AAC MPEG2 LC – Mode – Fs – CRC.
 AAC MPEG4 LC – Mode – Fs – CRC.
 AAC MPEG4 LD – Mode – Fs – CRC.
 aptX – Mode.

D1:MPL2-064-MN-48

D2:G722

D1:MPL2-64-ST-48

D2:NOT AVAILABLE

III.2.2.4. Screen 4: encoding algorithm

This is similar to the Decoder described above, but will describe the encoding
algorithm instead.

The different algorithms are displayed in the same way as the Decoder outlined
above, except for the following modes:

 AAC MPEG2 LC – Bit rate – Mode – Fs – CRC.
 AAC MPEG4 LC – Bit rate – Mode – Fs – CRC.
 AAC MPEG4 LD – Bit rate – Mode – Fs – CRC.

Prontonet User’s Manual v410 26

If the Encoder is configured to automatic mode or if the Decoder is not
synchronised you will see the following:

III.2.2.5. Screen 5: LAN port configuration parameters

Here we see the IP address and mask.

III.2.2.6. Screen 6: General configuration

This shows the NET type and the audio input selected. Here are two such
examples:

a) NET = IP and analog audio input:

b) NET = ISDN and digital audio input with external sync:

III.2.2.8. Screen 8: IP connections

III.2.3 The BOOK Key

This key directly accesses the internal Address Book. By pressing this key we can
view and connect to entries in the Address Book. (note that to edit or modify
entries we must go instead to the BOOK option in the main menu). For making
connections however, the BOOK key works like this:

Pressing BOOK you enter the Address Book index:

Using the left and right navigation keys you can go through the different entries
in the Address Book index. By pressing OK we select the item that is on-screen.
Now the screen shows the number/numbers to call, or the IP address, depending
on which has been saved.

Pressing OK again will process this information, that is, the ProntoNet will
configure the Encoder according to the BOOK entry and make the connection
over ISDN or IP. However, if you press the right arrow instead you can simply
display the encoding mode saved.

IP1:MULTICAST RX

IP2:NOT AVAILABLE

<< BOOK[01] >>

L1:1234567890

L2:1234567890

E1:MPL3-128-MN-48

When you press the BOOK key you will only be shown stored entries that
are relevant to the NET that is currently activated. So when NET = ISDN,
you will only be able to browse previously stored ISDN entries, just as
when NET = IP you will only be able to select from relevant IP addresses.

Chapter IV

THE MENU

By pressing OK on the navigation keys you enter the system’s main menu
from the default STATUS screen. We shall take a close look at the different
options available in the system menu. To aid in this, we recommend the reader
to have to hand the hierarchical menu tree in the appendices of this manual.

IV.1 The Controls: Navigation keys

Using the on-screen menus the user can control all the functions of the
ProntoNet. Using the ⇐, ⇑ and ⇒ keys it is possible to move around the system
menus and with the OK key select the desired options. Here is some more detail
on each of these keys:

⇒ : Moves to the menu option on the right. When we reach the last option, a

further press of this right arrow will cycle us round again to the first option, i.e.
we go to the left-most end of the list. The option that is available for selection
will appear on the display inside brackets ( {} ).

⇐ : Moves to the menu option on the left. When we reach the first option, a

further press of this left arrow will cycle us round again to the last option, i.e. we
go to the right-most end of the list. The option that is available for selection will
appear on the display inside brackets ( {} ).

⇑ : Returns to the previous level of the menu. If we keep pressing this key we

will leave the system menu completely and return to the STATUS screen.
OK : This selects or confirms the option that is selected (between the brackets)
and where relevant activates the subroutine associated with this option.

IV.2 Main Menu:

The main menu has the following options:

 NET: This allows us to select the communications port required.
 ENC: Here you can configure Encoders 1 and 2
 CONF: Here you can configure various general parameters of the unit, for

instance selecting the audio input or setting up the LAN port.

 INF: From here you can obtain information on the software version and

various configuration parameters of the ISDN port.

MAIN MENU

IV.3 NET: Selecting a communications port.

The ProntoNet has three different communication ports that allow the unit to
operate over three distinct types of network: IP, ISDN and dedicated digital
networks (X21 port).

 The NET option is only available if the lines are not already connected. If they

are busy, the display will show the following text:

 Each NET type selection will of course have their own set of configuration

parameters, as will be seen next.

IV.4 ENC: Encoder algorithm selection menu

From this option we can choose the audio Encoder algorithms. Note that the
ProntoNet can operate as a DUAL codec when ISDN is selected as the
communications interface. In this case, it is possible to have two simultaneous
communications that are totally independent and so it is possible to configure the
second Encoder. However, there are operational restrictions in the configuration
of Encoder 2 that depend on the algorithm and mode already selected for
Encoder 1. In chapter VI these restrictions are described in more detail.

If we select ENC from the main menu the following is displayed:

The ENCODER 2 option is only available if NET = ISDN.

IV.4.1 Configuration of Encoder 1:

The configuration of Encoder 1 (and Encoder 2 where available) is done in
stages, starting with the selection of an algorithm and following on with the
different parameters that relate to that particular algorithm. The ProntoNet menu
will always only display the options and parameters that are relevant to each
algorithm’s configuration. Additionally there are certain restrictions associated
