Chapter 1: Overview
Echo-Cancellation
Users connecting their TE430 Series cards 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 TE430 Series cards, unless otherwise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk maintains a number
of open source echo cancelers. These open source echo cancelers provide
a moderate level of echo cancellation, but are not capable of dealing with
higher levels of, or more advanced, echoes.
Digium recommends that those users concerned about echo cancellation
purchase the VPM128 hardware echo cancellation module. The VPM128
may be combined with the TE435 (as TE435B) or TE436 (as TE436B)
cards.
The VPM128 is designed to handle up to 128ms of echo cancellation
across all channels and provides a G.168 compliant echo cancellation
solution.
If equipped and not explicitly disabled in chan_dahdi.conf, the VPM128
will automatically operate and cancel all network echo within its tail
range (1024 taps). Users may also purchase Digium's commercial HPEC
software:

Chapter 1: Overview
What is Asterisk®?
Asterisk is the world’s leading open source telephony engine and tool kit.
Offering flexibility unheard of in the world of proprietary
communications, Asterisk empowers developers and integrators to create
advanced communication solutions...for free. Asterisk is released as open
source under the GNU General Public License (GPL), and it is available
for download free of charge. Asterisk is the most popular open source
telephony software available, with the Asterisk Community being the top
influencer in VoIP.
Asterisk as a Phone Switch (PBX)
Asterisk can be configured as the core of an IP or hybrid PBX, switching
calls, managing routes, enabling features, and connecting callers with the
outside world over IP, analog (POTS), and digital (T1/E1/J1/BRI)
connections.
Asterisk runs on a wide variety of operating systems including Linux,
Mac OS X, OpenBSD, FreeBSD, and Sun Solaris. It provides all of the
features you would expect from a PBX including many advanced features
that are often associated with high end (and high cost) proprietary PBXs.
Asterisk's architecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-based telephony equipment using relatively inexpensive
hardware.
Asterisk as a Gateway
It can also be built out as the heart of a media gateway, bridging the
legacy PSTN to the expanding world of IP telephony. Asterisk’s modular
Digium, Inc. Page 19
Chapter 1: Overview
architecture allows it to convert between a wide range of communications
protocols and media codecs.
Asterisk as a Feature/Media Server
Need an IVR? Asterisk’s got you covered. How about a conference
bridge? Yep. It’s in there. What about an automated attendant? Asterisk
does that too. How about a replacement for your aging legacy voicemail
system? Can do. Unified messaging? No problem. Need a telephony
interface for your web site? Okay.
Asterisk in the Call Center
Asterisk has been adopted by call centers around the world based on its
flexibility. Call center and contact center developers have built complete
ACD systems based on Asterisk. Asterisk has also added new life to
existing call center solutions by adding remote IP agent capabilities,
advanced skills-based routing, predictive and bulk dialing, and more.
Asterisk in the Network
Internet Telephony Service Providers (ITSPs), Competitive Local
Exchange Carriers (CLECs) and even first-tier incumbents have
discovered the power of open source communications with Asterisk.
Feature servers, hosted services clusters, voicemail systems, and pre-paid
calling solutions, all based on Asterisk have helped reduce costs and
enabled flexibility.

Chapter 2: Card Installation
T1/E1 Selection
The TE430 Series cards can be configured for either T1 or E1 mode. The
T1/E1 mode may be specified in the drivers using either the
default_linemode=t1 or default_linemode=e1 module parameter when
the drivers are loaded. This will set the mode for all spans on the card.
T1 Mode (Recommended Method) - Include the following in
/etc/modprobe.d/dahdi.conf:
options wcte43x default_linemode=t1
T1 Mode (Alternate Method):
# modprobe wcte43x default_linemode=t1
E1 Mode (Recommended Method) - Include the following in
/etc/modprobe.d/dahdi.conf:
options wcte43x default_linemode=e1
E1 Mode (Alternate Method):
# modprobe wcte43x default_linemode=e1
Connecting Timing Cables
The timing port allows up to four TE430 Series cards to share the same
sync (timing) source from the T1 line provider, or provide a consistent
sync source across multiple cards. This is a useful feature for fax modes
and some voice applications to prevent corruption due to timing slips on
the second, third or fourth TE430 Series cards.
Digium, Inc. Page 26
Chapter 2: Card Installation
To utilize this feature, daisy-chain the P3 connector between each TE430
Series card using the Digium 4-position timing cable. See Figure 6 on
page 26 for an example. Enable this feature in the drivers using the
timingcable=1 switch when the drivers are loaded:
# modprobe wcte43x timingcable=1

2: 64-bit 3.3 volt PCI Slot
3: 32-bit 5.0 volt PCI Slot
4: PCI Express 1-lane (x1) Slot
5: PCI Express 4-lane (x4) Slot
6: PCI Express 8-lane (x8) Slot
7: PCI Express 16-lane (x16) Slot
Figure 7: Motherboard Slots
Digium, Inc. Page 29
Chapter 2: Card Installation
The TE435/TE435B card is keyed for a PCI Express 1-lane (x1) slot and
will work in any PCIe revision 1.0 compliant slot, including lane lengths
x4, x8, and x16. This means that in the motherboard shown in Figure 7 on
page 28, the TE435/TE435B card will fit into Slots 4, 5, 6, or 7 (PCI
Express), but cannot fit into any of the other slots.
The TE436/TE436B cards are 32-bit 33 MHz cards keyed for universal
3.3 volt or 5.0 volt operation and work in any PCI 2.2 (or greater)
compliant slot. This means that in the motherboard shown in Figure 7 on
page 28, these cards will fit into Slots 1, 2, or 3 (PCI slots), but cannot fit
into any of the other slots.

Configuration
The TE430 Series cards have a variety of configuration options. This
chapter provides configurations for PRI, channel bank, and E&M wink.
These sample configurations are provided to assist you in familiarizing
yourself with the flexibility of editing the configuration files to meet your
specific needs. The list of possible configurations is too expansive to
cover in this user manual.
Digium, Inc. Page 39
Chapter 3: Configuration
Configuring Card Features
You will need to modify the chan_dahdi.conf file which is located in the
/etc/asterisk directory in order to configure the essential features of your
card. This file is the configuration layer between DAHDI and Asterisk.
Switchtype:
national: National ISDN 2 (default)
dms100: Nortel DMS100
4ess: AT&T 4ESS
5ess: Lucent 5ESS
euroisdn: EuroISDN
ni1: Old National ISDN 1
qsig: Q.SIG
Echocancel:
Echo Cancellation is enabled in chan_dahdi.conf by preceding the
channel variable with a variable called echocancel and its length in taps (#
of milliseconds multiplied by 8); for example:
echocancel = yes
channel => 1-23
By default, and when setting to "yes," echo cancellation is enabled and set
to 16 ms (128 taps). Echo cancella sabled by setting:tion is explicitly di
echocancel = no
Digium does not recommend that users set echo cancellation to "no."
Users of open source Asterisk-based echo cancelers also have the
following options:
echocancel = 128 (this sets 128 taps or 16ms)
Digium, Inc. Page 40
Chapter 3: Configuration
or
echocancel = 256 (this sets 256 taps or 32ms)
Users of Digium's HPEC software have the following additional options:
echocancel = 512 (this sets 512 taps or 64ms)
or
echocancel = 1024 (this sets 1024 taps or 128ms)
Please note that HPEC consumes extremely high amounts of CPU MIPS
that increase as the number of taps are increased. Audio quality issues
may result from choosing a taps length greater than the server's ability to
process the echo in real-time. If audio quality is affected, reduce the taps
length or combine your TE430 Series card with Digium's VPM128.
Users of Digium's VPM128 hardware echo cancellation module will have
128ms of echo cancellation performed at all times unless explicitly
disabled by setting the echocancel variable equal to "no."

Signalling:
pri_cpe for CPE side
pri_net for NET side
If you have a T1 PRI, add these lines to the following lines of the sample
file.
signalling = pri_cpe

group = 1
context = incoming
channel => 1-23
E1 PRI
signalling = pri_cpe

2. Specify the two letter country code for your loadzone and defaultzone.
This will preload tone zone data and specify a default tone zone for
your interfaces.
The following is a typical setup for a telco in the US:
loadzone = us
defaultzone = us
3. Configure the SPAN Map.
For each T1/E1 you are using, you will need to define a span. The
SPAN map includes defining the SPAN number, timing, line build out,
framing, and coding. Configuration details for each of these items is
explained in this section.
span => <Number>,<Timing>,<Line Build
Out>,<Framing>,<Coding>[,Yellow]
Number:
This is the port the T1/E1 line is plugged into. Port 1 being the furthest
span from the PCI bus. The port numbers are noted on the PCI bracket.

Timing:
This determines how timing is handled by the card.
0 - This span is not used to determine timing. If all spans on the card
are set to 0, the card will use its internal clock as the timing source.
1, 2, 3,... - A value greater than 0 will cause the span to attempt to
recover a clock source from the line for the entire card to use as
timing. Since only one source of timing is valid per card, this value
defines a priority that determines which span recovers a clock in the
case that multiples are defined. One is the highest priority span,
followed by 2, 3, and so on.
Only one span can be defined to take timing, and it defines timing for
the rest of the card’s spans.
Line Build Out:
For most setups the line build out is 0.
0: 0 db (CSU) / 0-133 feet (DSX-1)
1: 133-266 feet (DSX-1)
2: 266-399 feet (DSX-1)
3: 399-533 feet (DSX-1)
4: 533-655 feet (DSX-1)
5: -7.5db (CSU)
6: -15db (CSU)
7: -22.5db (CSU)

linux package. You can specify the echo canceller to be used for each
channel. The default behavior is for there to be no echo canceller on
any channel. So, it is very important that you specify one in the
system.conf file if you do not have hardware echo cancellers and need
echo cancellation. The format is:
echocanceller = <echocanceller name>,<channel(s)>
A list of valid echo cancellers are specified in the sample system.conf
file.
The following is a typical setup for a T1 PRI in the US using software-
based echo cancellation:
echocanceller = mg2,1-23
