INTRODUCTION
An Introduction to ISDN
ISDN (Integrated Services Digital Network) is a digital network capable of providing the
end user with high speed data, voice and image transmission at the same time. A way of
accessing the network, is by using the (Basic Rate Access or BRA or 2B+D)
communication protocol which supplies three channels to the subscriber. Two of these
channels are 64kbps channels (B-channels) used for the transmission of voice or / and
data, while the third one is a 16kbps channel (D-channel), used for signalling transmission
between the ISDN Exchange and the Network Termination NT1.
Figure 1: The basic rate access connection (BRA) between the subscriber and the
ISDN network
The connection of a subscriber terminal device to the network requires an intermediate
device, called Network Termination 1 or NT1. The device is installed at the subscriber
side and is connected to the ISDN Exchange via a simple 2-wire line, known as U-line
(Figure 1). The U-line transfers the digital signal that corresponds to the 2B+D channels.
Different types of terminal devices can be connected to the NT1 (ISDN or plain analogue
terminals). In order to cover up the different subscriber’s needs, INTRACOM offers the
following types of Network Termination units:
• netCon
• netCon+
• netMod
6

User’s Manual of netMod Network Termination Unit
netCon
netCon offers to the subscriber the possibility of connecting up to 8 ISDN terminal devices
to the ISDN network. The connection is via a 4-wire cable, known as the S-bus. netCon
has two RJ-45 jacks used for the connection of the ISDN terminal devices to the S-bus. Up
to 8 ISDN terminal devices can be connected as described in the paragraph “Connecting
an ISDN Device” on page 18.
netCon+
netCon+ besides offering the possibility of connecting ISDN terminal devices to the ISDN
network, also offers the possibility of connecting plain analogue devices (like analogue
telephones, FAX G3, analogue modems, etc.). The connection of plain analogue devices
is made via the two analogue ports (RJ11-jacks), while at the same time the connection of
up to 8 ISDN terminal devices is made via the two RJ-45 jacks of the S-bus (see
paragraphs “Connecting Analogue Devices” and “Connecting an ISDN Device”, on page
17 and 18 respectively).
netMod
netMod, besides offering the possibilities of connecting ISDN terminal devices and plain
analogue devices to the ISDN network, also offers the possibility of connecting a Personal
Computer (PC) to the Internet (or similar networks) without using any extra equipment.
The connection of up to 8 ISDN terminal devices is made via the S-bus, while the plain
analogue devices are connected through the two analogue ports and the Personal
Computer (PC) through the asynchronous serial port (RS232) or the USB port, (see
paragraphs “Connecting Analogue Devices”, “Connecting an ISDN Device” and
“Connecting a Personal Computer”, on pages 17, 18 and 19 respectively).

User’s Manual of netMod Network Termination Unit
The connection of NT1 type devices to the ISDN exchange and to the subscriber terminal
devices is shown in Figure 2.
Figure 2: Connections of NT1 type devices
Figure 2 clearly shows (shade levels) that netMod surpasses the potentiality of netCon+,
and netCon+ surpasses the potentiality of netCon.

User’s Manual of netMod Network Termination Unit
FAMILIARIZATION WITH netMod NETWORK TERMINATION UNIT
netMod is equipped with:
• 2×RJ-45 jacks for ISDN terminal devices connection. These jacks are the S-Interface
(S-bus) ports of the device.
• 2×RJ-11 jacks for analogue terminal devices connection. These jacks are the
analogue ports (ab1 and ab2) of the device.
• an RJ-11 jack for two wire U-line connection.
• a DB-9 connector to connect the personal computer (PC). This connector is the serial
port RS232 of the device.
• a USB receptacle to connect the personal computer (PC).
• a power supply cable of 230VAC.
netMod offers the following functions and capabilities:
• transmission of data to the serial port with rates up to 230.4 kbps, to and from the
connected personal computer (PC), for point-to-point connections or Internet access.
Note that most of the personal computers do not support rates of 230.4kbps on their
serial port, so the rate is limited to 115.2kbps. In this case a peripheral card is added to
the PC, in order to support the desired rates of 230.4kbps.
• transmission of data to the USB port Ver. 1.1 compatible (with rates up to 12Mbps) for
full availability of the bandwidth of 128kbps.
• interoperability with any operating system (Linux, Macintosh, Windows’
95/98/NT/ME/2K/XP etc.) using non-proprietary protocols.
• PPP (Point-to-Point Protocol) synchronous to asynchronous conversion for 64kbps
communication.
• B-channels bundling with Multilink-PPP support up to 128 kbps.
• PPP over X.25 over D channel protocol for Always On/Dynamic ISDN (AO/DI) use and
X.25 applications.
• transparent operation between B channels and data ports (RS232 or USB).
• bandwidth allocation protocols BACP/BAP.
• bandwidth allocation adjustments depending on the demands and the transmission
conditions (Bandwidth on Demand).
• transparent data and signalling transmission to the S-bus.
• support of supplementary ISDN services on the analogue ports.
• Second flash memory for easy and convenient firmware upgrade.

User’s Manual of netMod Network Termination Unit
Installation of netMod
netMod can be wall mounted or desktop. Wall mounting is achieved through the two
mounting points, located on the back side of netMod (the distance between the two
mounting points is 10cm), as shown in the next figure.

User’s Manual of netMod Network Termination Unit
To install netMod follow the instructions given below (see Figure 4):
• Connect the U-line (2-wire cable of the ISDN service provider)
to the corresponding RJ-11 jack.
• Plug the AC cable to the AC mains.
• Check the orange LED status on the topside of netMod: The
AC Mains Power LED (M.P.) should be lit.
• Depending on the devices that you want to connect, use the relevant jacks:
• RJ-11 jacks (ab1, ab2) for the analogue devices (analogue telephone, fax).
• RJ-45 jack for the ISDN terminals.
• RS232 serial port for the personal computer (PC).
• USB port for the personal computer (PC)
Figure 4: netMod’s Connections

User’s Manual of netMod Network Termination Unit
Follow the steps hereafter in order to install the netMod:
• Turn off the power of the PC (only for RS232 connections).
• Connect the male end of the 9-pin cable to the serial port of netMod or the USB
connector to the USB receptacle of the netMod
• Connect the female end of the 9-pin cable to the computer’s serial port or the USB
connector to the USB receptacle of your PC
• Turn the PC on.
The installation of netMod as a PC peripheral unit is described in
the chapter “CONNECTING TO A PC”.
Never connect the serial port cable to a device currently in use.
The device can be damaged.
Especially for the USB installation we suggest to follow the
instructions described in the chapter “CONNECTING TO A PC”.
