1. General overview

What is BR4 - Appliance?

BR4 - Appliance is a Blackfin DSP based Asterisk driven, S/T interface

embedded appliance. It is an open source embedded platform based on
uClinux and SwitchFin.

Basic Rate Interface is Integrated Services Digital Network
configuration that consists of two B channels (64 kbits/s “bearer” channels) used
for voice and data. And one D channel (16 kbits/s “data” channel).
The physical interface is called S/T. It uses four wires with a separate pair of
wires for the uplink and another pair for the downlink.
The typical use of the BRI interface is in residential solutions.
The mISDN ports can be configured for PTP or PTMP mode. PTP (Point to
Point) is a type of connection restricted to two end points.
PTMP (Point to Multi Point) is a type of connection, providing multiple pats
from a single point to multiple points (locations).

1.1. Echo cancellation module

Echo cancellation module installed in BR4 - Appliance

To ensure carrier grade voice quality, BR4 - Appliance can accept an
optional line echo cancellation module based on G.168 standard.
Echo cancellation is a process of removing the echo from a voice
communication in order to improve voice quality on a telephone call. In general
there are two sources of echo in the telephony: Acoustic echo and echo from the
analog phone hybrids.
delay often make these echoes more severe in telephone networks.

To achieve consistent quality we have selected
Zarlink. There is a special connector inside the BR4 - Appliance, where user can
plug an optional LEC module. If you have LEC-64-BR4 installed in your BR4 –
Appliance it will be detected and configured automatically.

2.1. System: uClinux, SwitchFin
Our PBXs are driven by our own telephony oriented, Open Source uClinux
distribution called SwitchFin ( http://switchfin.org). Current version of
SwitchFin provides Asterisk 1.4.x and mISDN 1.2 together with custom kernel
modules to support our hardware. Additional applications such as PPPoE, SMTP
forwarder, NTPd and many more are also provided to extend usability of the
BR4-Appliance under different scenarios.

2.2. Hardware:

• ADSP - BF537 600MHz CPU. DSP core for the media processing.

• 64MB of SDRAM

• 256KB serial flash for the boot-loader

• 256MB NAND flash for voicemail and prompts.

• SD card interface on a dedicated bus.

• Watchdog timer

• Optional, hardware based, G-168 Line Echo Cancellation.

2.3. Interfaces

• QUAD ISDN (2B + 1D) interface

• TE with PTP and PTMP

• EuroISDN (mISDN)

• 10/100Mbps Ethernet port with high performance PHY

• RS232 for console connectivity (115k, 8-N-1)

2.3.1. Interface cables

• For the Ethernet connection you have to use:

-In case you connect to router, switch and etc. Ethernet patch cable

The default SSH credentials are username: root, password uClinux

• ISDN ports – the BR4 PBX has 4 ISDN ports:

Pin Description

3 TX+
6 TX­4 RX+
5 RX-

• To connect the BR4-Appliance (TE mode) ISDN port to your

telecommunication equipment you should use standard Ethernet
“patch” cable. The configuration is:

BR4 - Appliance User Manual v2.0

8/48

Page:

Keep in mind that if you want to use BR4-Appliance in NT mode
you will need an ISDN crossover cable as shown below (pins
enumeration according standard RJ45 male connector, see above):

You will need to use 100Ω external resistive termination (between
both TX+,TX- and RX+,RX-) at the NT end of the ISDN cable. For
example assume BR4-Appliance1 is set to NT mode, BR4­Appliance2 is TE mode. We will terminate at BR4-Appliance1
side (refer to the picture above). You need to put a resistor between
pins 3-6 and another one between pins 4-5. BR4-Appliance doesn’t
provide phantom power on its ISDN ports. If you are connecting
ISDN telephone which requires power from the ISDN line you
have to implement this externally

• Serial Port cable

You need serial patch cable for the console access to your PBX from a PC.
The schematic of the cable is:
The default console port credentials are username: root, password uClinux

3.23.1 Updating your BR4 firmware

Your BR4-Appliance can be updated over the network.

Here you have to select “Firmware update”

In case you are equipped with recent u-boot (newer then ub2.30) you
can simply connect to your PR1-Appliance using console cable, restart
the PBX and interrupt the auto-boot process. In u-boot prompt type:
>run upgrade
This will download the latest version of u-boot and uImage for your
BR4-Appliance PBX and will store it in the non-volatile memory.
Note that this way of upgrade will clean your PBX settings! If you
have older version of u-boot you need to upgrade to ub2.30 or more
recent one manually (in order to get this automatic procedure
working.) To do this, please download the latest u-boot from our
download section at www.switchvoice.com

. Now you can put it in
your local TFTP server directory and load it in the BR4-Appliance like
this
>tftp 2000000 u-boot-br4-ub2.30.ldr

>eeprom write 2000000 0 $(filesize)

If you don’t have TFTP server you can use the console interface. Start
the receiver, with the loadb command, and then escape to the terminal
program's send file option, and send the file. When you load the file to
your board, it'll go something like this:

>Loadb 2000000

Load Address: 0x2000000

Loading: ##########################

done

Bytes Transfered = 131120 (20030 hex)

>eeprom write 2000000 0 $(filesize)

• Alternative approach to upgrade your uImage is to use the GUI and

HTTP protocol. Go to Firmware upgrade and select HTTP URL.
You can reset or keep the PBX configurations using the provided
check box. Recent versions of the BR4-Appliance firmware you can
find in our download section at www.switchvoice.com
specify the full path and file name for upgrade. To get the full link you
can right mouse click on the requested item in our download section
and select “Copy Shortcut” if you use IE or “Copy Link Location” if
you use Ffirefox. Now you have the link (

http://www.switchvoice.com/files/uImage-br4-ui2.15.img

clipboard and you can paste it in the Firmware upgrade form like it is
shown bellow

• If you prefer you can update uImage using TFTP protocol instead of

HTTP. In this case please use switchvoice.com TFTP server. You
need to specify the uImage file name as well. The latest file name you
can check from our download section at www.switchvoice.com
uImages available in the download section are available from our
TFTP server (switchvoice.com) as well.

Please note that the uImage files included in our download folder are
with 32 bytes (0x20) MD5 check sum at the end of the file. In case you
use your local TFTP server you can still use the uImage files located in
our download folder but in the NAND flash you should save 32 (0x20)
less bytes then is TFTP transferred.

Important Note: If you do GUI firmware upgrade from versions

before ui2.12 even if you don’t enable “Reset Configs” check box you
will get the configuration of your PBX cleaned. Also after such an
upgrade depending of your network settings you may not have the
sounds prompts installed. You can check if you have the sounds
prompt as you click on the “Music on Hold” tab and select the default
class. You should see few files listed there, in case your sound prompts
are properly downloaded. If you don’t have them just adjust your PBX
network settings so you have Internet connectivity, connect to the
BR4-Appliance using SSH or Serial protocol and execute

./bin/create_sounds

• Of course you can compile Switchfin and create your own image.

Then you can download it using your own tftp / http server. This is
more advanced topic which we will not cover in that great details. Just
keep in mind that after compilation you will get two images uImage
and uImage-md5 in build_br4/images_br4/ folder. Please use uImage-
md5 for all updates through the GUI.

Example: You have to type the following information, and click the + Go
button. If you have a local TFTP server, you have to type its IP address
(192.168.1.2 in this example) and type the name of the uImage in the field
File Name.

*Important – In order to complete the upgrade of the unit you have to reboot the
system.
