Overview
The Digium B410P is a four port BRI line termination card, compatible
with Euro-ISDN. It is capable of serving as Terminal Equipment (TE) or
as a Network Termination (NT) device. When configured as an NT
device, it is the source of BRI lines as shown in Figure 1. The B410P can
also improve voice quality in environments where software echo
cancellation is not sufficient with hardware echo cancellation on board.
Note: The B410P does not support North American BRI.

Chapter 1: Overview
What is Asteri sk®?
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
software available, with the Asterisk Community being the top influencer
in VoIP.
Asterisk as a 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) 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
Vo i c e o v e r I P in m a n y p r o t o c o ls , a n d c a n i n t e r o pe r a t e w i th a l m o s t a l l
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
architecture allows it to convert between a wide range of communications
protocols and media codecs.
Digium, Inc. Page 12

Chapter 1: Overview
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? Ok.
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, pre-paid
calling solutions, all based on Asterisk have helped reduce costs and
enabled flexibility.
Asterisk Everywhere
Asterisk has become the basis for thousands of communications
solutions. If you need to communicate, Asterisk is your answer. For more

Chapter 2: Card Installation
Unpacking the Card
When you unpack your card, carefully inspect it for any damage that may
have occurred in shipment. If damage is suspected, file a claim with the
carrier and contact the reseller from which the card was purchased, or
contact Digium Technical Support (+1.256.428.6161). Keep the original
shipping container to use for future shipment or proof of damage during
shipment.
Note: Only qualified service personnel should install the card. Users
should not attempt to perform this function themselves.
Inspecting the Shipment
The following items are included in shipment of a B410P:

Digium, Inc. Page 15

Chapter 2: Card Installation
Identifying Communication Ports
The B410P card has four RJ45 ports and four status LEDs. The ports are
used for connecting Basic Rate ISDN (BRI) lines. Each port can be
configured as either TE or NT operation. The ports are numbered in
sequence from one to four. The top port is Port 1 and the bottom port is
Port 4. See Figure 2 on page 17 for appropriate identification of these
ports.
Note: It is important to identify the type of BRI line each port is
configured for, either TE or NT. You will need this information during
the Asterisk configuration.
Each RJ45 port is accompanied by a status LED. The status LEDs can
indicate the following:
Green - Card is in-sync with the far end.
Red - Card is not seeing far end, circuit is not up, or cable is bad.

Chapter 2: Card Installation
Selecting NT or TE Mode
There is a 5-position jumper on the board for each port to select between
NT and TE mode. This must be set before installing the card. Each of the
four ports can be set for TE or NT mode independently. This eliminates
the need to use a crossover cable. Place the jumper on the left side of the
connector for NT mode, or place it on the right side for TE mode as
shown in Figure 3. The default setting is TE mode. Notice in Figure 5 on
page 20 there is an additional set of jumpers which is reserved for future
use. These jumpers are not to be used at this time.
There is a risk of electrical shock due to lightning when this
device is utilized in TE mode. Take safety precautions when
using the card in this manner.
Note: Be careful when changing the jumper position.

Ter mi nat i ng t he NT Mode Li ne
There are DIP switches for each port used to add a 100 ohm termination
when the B410P is in NT mode. This switch should only be turned on in
those instances where a BRI is daisy-chained and terminated on the
B410P in NT mode. See Figure 4 for a detailed illustration of this setting.
This switch must not be turned on in TE mode. The default setting is Off.
Caution.
Only qualified service personnel should continue with
hardware installation and configuration of the B410P card.
Users should not attempt to perform these functions themselves.

Installing the Hardware
1. Now that you are acquainted with your card, power down your
computer and unplug it from its power source.
2. Attach a static strap to your wrist and open the case.
3. Check the NT or TE mode jumper setting to ensure it matches your
equipment configuration.
4. Remove the bracket place holder and insert the card into a PCI slot.
See Figure 6.
