5.17 Configuring Voice over DSL
Basic configuration of the Voice over DSL (VoDSL) settings in the CopperJet Integrated
Access Device (IAD) can be done through the WebServer Interface. Advanced
configuration can only be done through TELNET.
5.17.1 Basic VoDSL Settings
To configure the basic Voice over DSL settings, go to
Configuration menu
and click on
VoDSL
. The
VoDSL
page is displayed.
You need to add configuration information for VoDSL. This information must be provided
by your Voice over DSL service provider.
VPI
:
Virtual Path Identifier. A field in the ATM header. The VPI is
used to identify the virtual path that a circuit belongs to.
The VPI can be any value between 0 and 4095.
VCI
:
Virtual Channel Identifier. Part of the ATM header. The VCI
is a tag that identifies which channel a cell will travel over.
The VCI can be a value between 1 and 65535.
Coder Law:
ALAW is in general meant for Europe.
ULAW is in general meant for the US.
None
:
There is no VoDSL signaling configured.
CopperCom
:
CopperCom proprietary VoDSL signaling.
Paradyne/Jetstream
:
Paradyne/Jetstream proprietary VoDSL signaling.
BLES
:
BLES VoDSL signaling.
ELCP
:
ELCP
is a standard protocol that specifies the mechanism
where V5.2-based signaling messages are exchanged
between the VoDSL Gateway and IAD to support both
POTS (plain old telephone system) and ISDN voice over
ATM.

Chapter 5: Configuring the CopperJet
CAS
:
Channel Associated Signaling (CAS)
is used in bit-based schemes
where dedicated signaling bandwidth is required for every
connection.
Profile
:
Select ITU-T (voice over AAL2) or ATM-Forum (AF–voice traffic
over ATM (VTOA)). Profile Source and Identifier are only used for
BLES signalling (both CAS and ELCP). For voice gateways with an
ADPCM only mode (for all UUI values 0..15) the special atmforum
profile number 13 is used.
Proprietary test mode
:
This mode enables the internal PBX functionality for testing
the Voice ports.
Voice port 1: number 101
Voice port 2: number 102
Voice port 3: number 103
Voice port 4: number 104
When finished configuring VoDSL, click on
Apply.
Go to the
Configuration
menu and click
on
Save config
to save the new settings into the CopperJet.
5.17.2 Advanced Voice over DSL Configuration
Configuration of advanced Voice over DSL settings in the CopperJet IAD’s is done through
TELNET. To access the TELNET configuration mode, start a TELNET session from your
computer (i.e.
TELNET <ip-address>
) and enter your username and password (default
username and password are
admin, admin
). To access the advanced settings enter the
following commands:
console enable [enter]
iad [enter]
The prompt has changed into
<ip-address> iad>
.
5.17.2.1 Flash on hook timing
Because the requirements of flash on hook timing differ a lot per country, the minimum
and maximum hook flash time can be configured.
Syntax:
flashmin <value>
Minimum flash-on-hook time in milliseconds after a hook-flash is detected. Below this
value no flash nor hook state change is detected.
Syntax:
flashmax <value>
Maximum flash-on-hook time in milliseconds before a hook flash is detected. Above this
value a hook state change is detected.
Note: that if flashmax < flashmin, hook flash detection is disabled. Flashmin can be used
to set the minimum time a hook state change is detected.
Example: to set the minimum flash-on-hook timing to 60 milliseconds enter the following
command:
flashmin 60 [enter]
Example: to set the maximum flash-on-hook timing to 200 milliseconds enter the following
command:
Page 61
Page 64 / 86
Chapter 5: Configuring the CopperJet
flashmax 200 [enter]
5.17.2.2 Initial ring timing for CLIP
Because the requirements of the initial ring timing differ a lot per country, the initial ring
time can be configured.
Syntax:
initring <value>
Time in ms the phone will ring. After the ring is finished the End-of-pulse information
element will be send within a SIGNAL message to the CO.
Example: to set the initring value to 250 milliseconds enter the following command:
initring 250 [enter]
5.17.2.3 Network Time Reference Clock
Syntax:
pcmclk <value>
<value>
can be one of the following:
network
Use network as time reference.
networkcor
Use network as time reference with automatic correction
local
Use local/onboard oscillator as time reference.
Example: to set the internal clock reference to NTR enter the following command:
pcmclk network [enter]
5.17.2.4 Ring cadence configuration support
Because the requirements for ring cadences differ per country, a list of ring cadences can
be configured.
Syntax:
cadence <id>,<make1>,<break1>,<make2>,<break2>,<make3>,<break3>
<id>
The index number of the ringing pattern. This must equal the cadence
number send by V5 in case of ELCP. See also
5.17.2.5 Define Cadences
. Each ringing
pattern must have a unique id.
<makeX>
Time in milli seconds the phone is ringing.
<breakX>
Time in milli seconds the phone is silent.
-make 1-|
|-make 2-|
|-make 3-|
|- make 1|
|
|
|
|
|
|
|
|-break 1-|
|-break 2- |
|-break 3- |
|-
If the second or third period is not used, specify 0 as the make/break values for the first
unused period.
Note: that it is not possible to specify 0 for make2/break2 and a non zero value for
make3/break3.
A ringing pattern with make2/break2 and make3/break3 equal 0 would look like this:
-make 1-|
|-make 1-|
|-make 1-|
|- make 1|
|
|
|
|
|
|
|
|-break 1-|
|-break 1- |
|-break 1- |
|-

Chapter 5: Configuring the CopperJet
Example: to set the ring cadences enter the following commands:
cadence 0,2000,4000,0,0,0,0 [enter]
cadence 1,800,400,800,4000,0,0 [enter]
cadence 2,400,200,400,200,800,4000 [enter]
cadence 3,300,200,1000,200,300,4000 [enter]
cadence 4,500,5500,0,0,0,0 [enter]
5.17.2.5 Define Cadences
Syntax:
defcadence <id>
Specify the id that is used as default ring cadence from the cadence table.
In case of CAS signalling: The default cadence id is used at all times. In case of ELCP
signalling: If the id, sent by the V5 network, is not found in the cadence table, the default
id is used.
Note: that if the default cadence id does not exist in the table, id 0 is used.
5.17.2.6
Echo Cancellation
The IAD complies with G.168:
The echo cancellers covered by this Recommendation should be equipped with a tone
detector that conforms to this sub clause. This tone detector should disable the echo
canceller only upon detection of a signal which consists of a 2100 Hz tone with periodic
phase reversals inserted in that tone, and not disable with any other in-band signal, e.g.,
speech, or a 2100 Hz tone without phase reversals. The tone disabler should detect and
respond to a disabling signal which may be present in either the send or the receive path.
The IAD is detecting the tone in both directions. The Phone LED indicates the status of the
echo canceller:
Stays ON continuously, echo canceller is ON in both directions.
600ms ON 100ms OFF the echo canceller is OFF in one direction.
1600ms ON 100ms OFF the echo canceller is OFF in both directions.
