Echo-Cancellation
Chapter 1: Overview
Administrators connecting their Gateway Series appliances to the PSTN
or other devices are likely to be placing calls that will result, at some
point, in an unbalanced 4-wire/2-wire hybrid. The result of this hybrid is
the reflection of a near-end echo to the calling party. Elimination of this
echo is the responsibility of echo cancellation.
The Gateway Series appliance utilizes hardware-based voice processors
for echo cancellation an d codec tra nscoding. Its hardware echo canceller
is designed to handl e up to 128m s of e cho cancel lation ac ross a ll channe ls
and provides a G.168 compliant echo cancellation solution.
If not explicitly disable d in the Gateway Series web GUI, the hardwarebased echo canceller will automatically operate and cancel all network
echo within its tail range (1024 taps).

Chapter 2: Unit Installation
This sectio n describes how to properly inst all the hardware for a Gateway
Series appliance.
Caution
Only qualified service personnel should continue with
hardware installation and configuration of the Gateway Series
appliance. Users should not attempt to perform these functions
themselves.
Caution
This equ ipmen t is i nt e n d e d fo r u s e in Restricted Ac ce s s A reas
only where equipotential bonding has been applied.
Grounding
The Gateway Series appliance must be proper ly earth gr ounded for safety
reasons. If the unit is not properly earth grounded, the unit and/or other
equipment connected to the unit could be damaged. If a Gateway Series
appliance is damaged while it is imprope rly grounded, the warranty on
the Gateway Series appliance is void.
A ground lug is located on the opposite side from the front panel of a
Gateway Series a pplian ce. Atta ch an a ppropr iate l eng th and gauge of wire
to the double-crimp ground ring terminal. The wire length should be as
short as possible, and gauge should be 18 AWG or greater. Stra nded or
solid wire is acceptable . Wire is not provided with the Gateway Series
Digium, Inc. Page 24
Chapter 2: Unit Installation
appliance. Double crimp the ground ring terminal to the wire. Next, slide
the ground ring terminal over the ground lug. Then fasten the ground ring
terminal to the ground lug using the gro und nut. The ground nut must be
turned clockwis e to tigh ten it o nto th e groun d lug. The opposite end of the
wire that is connected to the ground ring terminal should be securily
fastened to an unpainted metalic section of a properly earth grounded
equipment rack. A connector for the opposite end of the wire is not
provided with the Gateway Series appliance.
Note: Taking into considera tion the requirements of all equipment
connected to or sharing the rack, the equipment rack should be
properly earth grounde d. Ref er to the manu facturer of the rack for
instructions on how to properly e arth ground the rack.
Important
Use only a grounded electrical outlet when connecting the
Gateway Series appliance to a power sour ce. If you do not
know whether the outlet is grounded, consult wi th a qualified
electrician.
Digium, Inc. Page 25
Chapter 2: Unit Installation
Mounting
The included hardware allows the Gate way Serie s appliance to be wall
mounted, rack mounted side-by-side with another Gateway Series
appliance, or placed flat on a leve l surface. If a single Gateway Series
appliance is to be rack mounted, the optional long mounting bracket (not
supplied, part number 3244-00042) must be used. The optional long
mounting bracket can be ordered by contacting a Digium reseller or
Digium directly.
Important
Reliable ear th grounding of ra ck-mount equipment should be
maintained. Particular atte ntion should be given to provide
connection other than direct connections to the branch circuit
(e.g., use of power strips).
Important
Mounting of the Gateway Series appliance in a rack should be
such that no hazardous condition is achieved due to uneven
mechanical loading. Do not place heavy obje cts on top of the
unit, or pull down on the mounted unit. Consider the
mechanical l oadi ng of ex terna l cable s. The wei ght of th e cable s
can pull on the unit and create unev en loading. Secure heavy
cables with external cable trays.
Important
If rack mounting, ins tall the Gateway Ser ies appliance in a rack
so that the amount of airflow r equired for safe operation is not
compromised.
Digium, Inc. Page 26
Chapter 2: Unit Installation
Important
If the Gateway Series appliance is installed in a system that is
in turn installed in a closed or mu lti-unit rack ass embly, the
operating ambient temperature of the rack environment may be
signific antly greater t han the room ambient. Whi le the
maximum safe operat ing temperature is 50°C, consideration
should be given to ins talling the unit in an environment
compatible with the maximum recommended ambient
temperature of 45°C for long ter m reliabili ty and maximum
performance.

the DHCP server on the network. The DHCP server on the network
will need to be accessed to determine the IP address assigned to the
Digium, Inc. Page 33
Chapter 2: Unit Installation
Gateway Series appliance. The default username for the Gateway
Series web GUI is admin, and the default password is admin.
Note: The Gateway Series appliance may also be accessed by its
hostname. The hostname will be in the format of Gx00-aa-bb-cc,
where x is 1 for G100, 2 for G200, 4 for G400 or 8 for G800, aa is the
6th to last a nd 5th to la st alphanum eric of the unit’s first MAC addre ss,
bb is the 4th to last and 3rd to last alphanumeri c of the unit ’s first
MAC address, and cc is the 2nd to last and very last alphan umeric of
the unit’s first MAC address. The MAC addresses of the Gateway
Series appliance are printed on a label on the back of the unit. For
example, if the f irst MAC addr ess of a G200 Gatewa y Seri es a ppliance
is B2432B187135, the hostname will be G200-18-71-35. HTTPS (e.g.
https://[IP]) must be used. If you do not connect using HTTPS, a
browser error will be displayed.
3. It is highly recommended that the admin password be changed using
the System Admini s trators menu on the web GUI.

is forgotten, a firmware recovery may need to be performed. The USB
Recovery port can be used to perform a firmware recovery using a
recovery image. The recovery image reformats the Gateway Series’ root
filesystem and reload s the appr opriate software on it. It will also
overwrite the configur ation database, returning the Gateway Series
appliance to its default configuration.
Note: It is highly r ecommended to us e an im ag e tha t is equ al or
greater in version than the fi rmware that is currently installed on the
Gateway Series applianc e.
Every Gatew ay Series firmware release will incl u de a reco very image.
The recovery image is located inside of a compressed zip file which can
be download ed fro m
http://downloads.digium.com/pub/telephony/gateway/recovery/. After
downloading the recovery image , the contents of the compressed zip file
must be extracted and copied to the root (i. e. p arent) directory of an
empty USB flash drive.
Note: A USB flash drive is not provided with a Gateway Serie s
appliance. It must be purchased separately. The USB flash drive
should be at least 2GB in size and formatted with the FAT32
filesystem.
Note: Some decompression utilities will create a new directory in
which to place extracted files. If your decompression utility functions
in that way, be certain to copy the contents from that new dire ctory to
the root (i.e. parent ) dire ctory of an empty USB flash drive. Any new
directory created by a decompression utility should not be copied.

Chapter 4: Troubleshooting
Next, power off the Gateway Series appliance.
Note: For hardware revisions A3 and earlier, the Gateway Series
appliance must remain powered off for 60 seconds in order to
guarantee proper star tup. S ee the label on the back of the Gateway
Series appliance to dete rmine t he hardware revision.
Then insert the USB flash drive into the USB Recover y port. Power on
the Gateway Series appliance . The Gateway Series appliance will boot
from the USB Recovery port and process the recovery image which was
placed on the USB flash drive.
Warning! Do not disconnect po wer during thi s process. The recovery
process will take at least 3 minutes to complete.
During this process, the Device Status LED will turn red for a fraction of
a second. Then it will turn amber for less than a minute. Next, it will run
red for about 2 minut es. Lastl y, the Device S ta tus LED will r emain of f. At
this point, it is safe to power off the Gateway Series appliance. Remove
the USB flash drive and power cycle the Gateway Series appliance.

Chapter 4: Troubleshooting
What type of c able do I need for the T1/E1 ports on a Gateway Series
appliance?
A straight-through RJ45 T1/E1 cable is needed for connecting to the RJ45
ports on a Gateway Series applianc e when connec ting to the PSTN. If
connecting to a TDM PBX, a crossover RJ45 T1/E1 cable may be
required. Use o n ly shielded cables to en su re co mpl i ance w i th th e
International EMC standar ds. The appropriate cables may be ordered
from Digium by visiting www.digium.com. Refer to Table A-2 on page
86 for pin assignments.
How can the Ga te w ay Se ri es softw a re be reini tiali ze d without
modifying any configuratio n settings?
The Gateway Series software can be reinitialized without modifying any
configuration settings by following the steps described below.
1. Press the reset switch once.
2. The status LED will flash amber for 5 seconds.
3. The status LED will flash red for 2 seconds, acknowledging the
reinitializ ation request.
4. The Gateway Series appliance will restart itself.
5. The status LED will turn green once the reinitialization is complete.
How can the Gateway Series GUI password be reset to its default
without modifying any configuration settings?
Digium, Inc. Page 81
Chapter 4: Troubleshooting
The Gateway Series GUI password can be reset to its default without
modifying any configuration settings by following the steps described
below.
1. Press the reset switch once.
2. The status LED will st art flas hing am be r.
3. Press the reset switch again while the sta tus LED flashes amber.
4. The status LED will flash green for 2 seconds, acknowledging the
reset password request.
5. The password is set back to its default (i.e. “ admin”).
There is a slight echo. How can I adjust the sound quality?
First, verify that the Echo Cancellation option under the Port # menu of
T1/E1 Settings is enabled. If it is not, ena ble it. If echo persists, adjust the
RX Gain and TX Gain options on the same menu. For the gain options, it
is recommended to shift only between values of -5 and 5.
How is the loopback test useful for troubleshooting?
The loopback test verifies the integrity of the data being transmitted and
received on the T1/E1 port by sending a pattern out of the T1/E1 transfer
pins and expecting t o see the same pa ttern c ome back on t he receive pins .
This test requires that the T1/E1 port be disconnected from any external
device and a loopback connector be inserted to the port. A loopback
connector has pin 1 looped to pin 4, and pin 2 looped to pin 5.
