Download and Install fonulator (RPM) configuration utility
The following instructions explain how to install the fonulator for Redhat based systems such as CentOS, Fedora Core
1. Download rpm
# wget http://support.red-fone.com/downloads/fonulator/fonulator-2.0.0-36.i386.rpm
2. Install RPM
# rpm -ivh fonulator-2.0.0-36.i386.rpm
3. Confirm fonulator has been installed properly by executing it from the command line
# fonulator -V
Copyright (C) 2007 Redfone Communications, LLC.
Build Number: 36
For advanced fonulator command line options execute with the --help flag.
# fonulator --help
1. Download sample redfone.conf file to your /etc/ directory;
# cd /etc/
# wget http://support.red-fone.com/downloads/fonulator/redfone.conf
2. The Fonebridge MOD-B firmware now uses IP based communication for
sending updates to the device. The default IP address of FB1 and FB2
are as follows:
3. Configure the server's Ethernet interface used to communicate with
the Fonebridge with an IP address from the same 192.168.1.X range.
# ifconfig eth1 192.168.1.200
Alternatively an alias IP address can be assigned to an existing IP interface;
# ifconfig eth1:0 192.168.1.200
NOTE: This IP should be made permanent and done with your Linux distro's
normal utilities for setting IP addresses.
4. Edit the redfone.conf file with your favorite text editor (nano,pico,vi, etc.)
5. Under the [globals] section change the server= MAC address to
reflect the MAC address of your server's Ethernet card that will be
communicating with the Fonebridge. You can determine the MAC address
of your interface by issuing the ifconfig ethN command in Linux.
# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:16:36:76:09:91
6. The port= parameter designates which foneBRIDGE Ethernet port will be used
to communicate with your Asterisk server. Valid options are 1 or 2 and correspond to FB1 and FB2 on the device Ex;
7. [spanN] parameters are used to set the individual configurations of
each T1/E1 port on the Fonebridge. Options per span include;
crc4= (used on some E1 lines)
rbs= Used for CAS/RBS type lines on Channel Banks, E&M, etc.
longhaul=0-3 (See LBO explanation at end of document)
loopback= Loopback to far end telco equipment for line testing
NOTE: MFC/R2 requires 'framing=cas'
A sample Quad T1 PRI redfone.conf might look like this;
A sample Quad E1 PRI redfone.conf might look like this;
Longhaul and Shorthaul LBO Overview
The 'longhaul' and 'shorthaul' parameters can be added under the [spanN] block of each span. These values should only be changed under advise from your TELCO.
Aything with longhaul means the Adaptive Equalizer is ON!
You can only choose longhaul or shorthaul, you cannot have both.
Longhaul Values (longhaul='value')
0 => 0dB (No Attenuation, just turns on Adaptive Equalizer)
1 => -7.5dB
2 => -15.0dB
3 => -22.5dB
Shorthaul Values (shorthaul='value')
0 => 0-133 feet
1 => 133-266 feet
2 => 266-399 feet
3 => 399-533 feet
4 => 533-655 feet
The 'loopback' parameter, placed under the [spanN] block places that span in a loopback
mode to be utilized by the Telco to test the T1/E1 circuit all the way to the fonebridge device. It is not useful for testing or debugging the Asterisk side of the connection or for running a local loopback.
On EC enabled foneBRIDGE2 the Echo Cancellation hardware is automatically configured based on the span information in redfone.conf. If it is an E1, it will be configured for EC on E1 lines and the same for T1. The foneBRIDGE2 normally ships with the uLaw companding mode enabled in the DSP. When configuring E1 spans the first time it may cycle power to the foneBRIDGE2 core in order to reset the DSP to aLaw companding which is the default for E1. This is a one-time occurrence.
8. Power on the fonebridge and once your redfone.conf file is complete you
will update the fonebridge by executing the fonulator utility. The
fonulator utility will read the information contained in your
redfone.conf and provided all IP addressing is correct, send it to the
fonebridge which will configure all of its spans as per your
parameters, come on line and begin transmitting TDMoE traffic.
Execute the fonulator utility from the Linux command line. Ex;
By default the fonulator will look for /etc/redfone.conf. You can
specify an alternative file name by affixing the full file name
path after fonulator. Ex;
# fonulator /etc/redfone2.conf
You can also query the device with fonulator to
determine what the current running configs are. Ex;
# fonulator -vq
Please note that if power is cycled to the fonebridge it will
loose its current configuration and you will need to fonulate
The system.conf file follows all standard rules and syntax as other
zaptel based hardware with the only exception being the use of the
NOTE: If using a Quad port Fonebridge you must always specify 4 dynamic
spans in system.conf even if you have only configured a single span on
the device. The same applies on the Dual port. Two dynamic spans must
always be specified even if only 1 span has been configured in
dynamic=ethmf,<ethN>,/<FB MAC address>,/<span number>,<numchans>,<timing>
A sample 4x T1 PRI configuration would like the following;
loadzone = us
In the above example, the Asterisk server is communicating on its eth1
with the fb address of 00:50:C2:65:D0:70. Span numbers start at 0. It
has 24 channels (E1 would be 31) and timing begins at 4.
A sample 2x E1 PRI configuration would look like the following;
# NOTE: Most E1 use alaw codec and this must be specified.
loadzone = us
After successfully installing dahdi, configuring redfone.conf and
system.conf you can now load the necessary dahdi modules.
1. Load modules
# modprobe dahdi
# modprobe dahdi_dynamic_ethmf
2. Confirm modules loaded properly with dahdi_tool
If you do not see any spans you may need to execute 'dahdi_cfg' and then check 'dahdi_tool'.
Once the Fonebridge device has been configured via the fonulator tool
you should see a YEL alarm (as shown above) at a minimum in dahdi_tool. If your PRI or other
telco equipment is already cabled and the Fonebridge has been updated
with the proper configuration parameters then you should see an OK
state in dahdi_tool.
6. Download and Install libpri and Asterisk 1.6
7. Edit /etc/dahdi/system.conf
8. Edit redfone.conf
