Chapter 3

Installing an analog station media bay module

You can connect a a maximum of eight analog telecommunication devices to the analog station
media bay modules (ASM8, ASM8+, and GASM). These devices are standard analog telephones,
cordless telephones, fax machines, answering machines, or modems. The maximum speed for a
modem connection is 28.8 kbit/s.

The ASM8 is available in North America only; the ASM8+ and GASM8 are available in North
America, the United Kingdom, Australia, and Poland.

In addition to ASM8 features, the ASM8+ and GASM offer the following features:

• Visual Message Waiting Indicator (VMWI)—LED indicates to the end user that a message is
waiting

• disconnect supervision (Open Switch Interval [OSI] according to EIA/TIA 464)—indicates to
the attached device, in an established communication, that the connected device must release
the call

19

Note: When disconnect happens from the central office (CO), the ASM8+

provides an OSI to the off-hook station of 850 ms (TIA/EIA 464 section

5.4.10.2.4; minimum is 600 ms) as a disconnect signal. If the station remains
on-hook after the disconnect signal, the ASM8+ disconnects the station equipment
from the network without returning a tone to it (TIA/EIA 464 section

5.4.10.2.5[1]). After the station equipment goes on-hook, the ASM8+ station
interface is restored to on-hook (idle).

You must ensure that the device, application, or interface card connected to an
ASM8+ station interface conform to these on-hook and off-hook conditions.

• caller ID—provides the name, phone number, and other information about the caller to the end
user at the start of the call

• firmware downloading capability—allows the system to upgrade the ASM8+ and GASM
firmware at customer sites

• enhanced ringing capability—ASM8+ and GASM provide a ringing voltage of two REN/65 V
rms per port.

• GASM8—designated as an on-premise station (OPS) port

The ASM8, ASM8+, and GASM each have one RJ-21 connector on the faceplate. Figure 1 on

page 20 shows the GASM faceplate.

Telephony Device Installation Guide

20 Chapter 3 Installing an analog station media bay module

Figure 1 GASM faceplate LEDs and connectors

The ringer equivalency number (REN) per port for ASM8 is 1; the REN for ASM8+ and GASM
is 2.

Note: The termination of the analog interface can consist of any combination of devices,
subject only to the requirement that the sum of the RENs of all the devices does not exceed
the REN of the interface to which the device is connected.

ISDN overview

The following provides some general information about using ISDN lines on your BCM50 system.
Detailed information about ISDN is widely available through the internet. Your service provider
can also provide you with specific information to help you understand what suits your
requirements.

Refer to the following topics for information:

• "ISDN fundamentals"

• “Services and features for ISDN BRI and PRI” on page 31

• “ISDN hardware” on page 36

• “ISDN standards compatibility” on page 38

• “Planning your ISDN network” on page 39

• “Supported ISDN protocols” on page 40

29

ISDN fundamentals

Integrated Services Digital Network (ISDN) technology provides a fast, accurate and reliable
means of sending and receiving voice, data, images, text, and other information through the
telecom network.

ISDN uses existing analog telephone wires and multiplex it into separate digital channels which
increases bandwidth.

ISDN uses a single transport to carry multiple information types. What once required separate
networks for voice, data, images, or video conferencing is now combined onto one common
high-speed transport.

Refer to the following topics:

• “Types of ISDN service” on page 30

• “ISDN layers” on page 30

• “ISDN bearer capability” on page 31

Analog versus ISDN

ISDN offers significantly higher bandwidth and speed than analog transmission because of its
end-to-end digital connectivity on all transmission circuits. Being digital allows ISDN lines to
provide better quality signaling than analog POTS lines, and ISDN out-of band data channel
signaling offers faster call set up and tear down.

While an analog line carries only a single transmission at a time, an ISDN line can carry one or
more voice, data, fax, and video transmissions simultaneously.

Telephony Device Installation Guide

30 Chapter 5 ISDN overview

An analog modem operating at 14.4K takes about 4.5 minutes to transfer a 1MB data file and a

28.8K modem takes about half that time. Using one channel of an ISDN line, the transfer time is

reduced to only 1 minute and if two ISDN channels are used, transfer time is just 30 seconds.

When transmitting data, the connect time for an average ISDN call is about three seconds per call,
compared to about 21 seconds for the average analog modem call.

Types of ISDN service

Two types of ISDN services (lines) are available: Basic Rate Interface (BRI) and Primary Rate
Interface (PRI). Each line is made up of separate channels known as B and D channels which
transmit information simultaneously.

• BRI is known as 2B+D because it consists of two B-channels and one D-channel.

• PRI is known as 23B+D(in North America) or as 30B+D (in Europe). In North America,
23B+D consists of 23 B-channels and one D-channel (T1 carrier). In Europe, 30B+D consists
of 30 B-channels and one D-channel (E1 carrier).

B-channels: B-channels are the bearer channel and are used to carry voice or data information and
have speeds of 64 kb/s. Since each ISDN link (BRI or PRI) has more than one B-channel, a user
can perform more than one transmission at the same time, using a single ISDN link.

D-channels: The standard signaling protocol is transmitted over a dedicated data channel called
the D-channel. The D-channel carries call setup and feature activation information to the
destination and has speeds of 16 kb/s (BRI) and 64 kb/s PRI. Data information consists of control
and signal information and for BRI only, packet-switched data such as credit card verification.

ISDN layers

ISDN layers refer to the standards established to guide the manufacturers of ISDN equipment and
are based on the OSI (Open Systems Interconnection) model. The layers include both physical
connections, such as wiring, and logical connections, which are programmed in computer
software.

When equipment is designed to the ISDN standard for one of the layers, it works with equipment
for the layers above and below it. There are three layers at work in ISDN for BCM50. To support
ISDN service, all three layers must be working properly.

• Layer 1: A physical connection that supports fundamental signaling passed between the ISDN
network (your service provider) and the BCM50 system. When the LED on a BRI S/T Media
Bay Module configured as BRI is lit, your layer 1 is functioning.

• Layer 2: A logical connection between the central office or the far end and the BCM50 system.
Without Layer 2, call processing is not possible.

NN40020-309NN40020-309

Chapter 5 ISDN overview 31

• Layer 3: Also a logical connection between the ISDN network (your service provider) and the
BCM50 system. For BRI lines, layer 3 is where call processing and service profile identifier
(SPID) information is exchanged. This controls which central office services are available to
the connection. For example, a network connection can be programmed to carry data calls.

Note: Throughout this chapter, references are made to Service profile
identifiers (SPIDs). SPIDs are a part of the BRI National ISDN standard.
SPIDs are not used in the ETSI BRI standard or on PRI.

These three layers are important when you are installing, maintaining, and troubleshooting an
ISDN system.

ISDN bearer capability

Bearer capability describes the transmission standard used by the BRI or PRI line so that it can
work within a larger ISDN hardware and software network.

The bearer capability for BRI and PRI is voice/speech, 3.1 kHz audio (fax), and data (unrestricted
64 kb/s, restricted 64 kb/s, or 56 kb/s).

Services and features for ISDN BRI and PRI

As part of an ISDN digital network, your system supports enhanced capabilities and features,
including:

• faster call set up and tear down

• high quality voice transmission

• dial-up Internet and local area network (LAN) access

• video transmission

•network name display

• name and number blocking (PRI, BRI and analog)

• access to public protocols

Refer to the following for additional information on features and services:

• “Network name display” on page 33

• “Name and number blocking” on page 33

• “Call by Call Service Selection for PRI” on page 34

• “Emergency 911 dialing” on page 34

• “Two-way DID” on page 35

• “Dialing plan and PRI” on page 35

Telephony Device Installation Guide

32 Chapter 5 ISDN overview

PRI services and features

The services and features provided over PRI lines include:

• Call-by-call service selection (NI protocol)

• Emergency 911 dialing, internal extension number transmission

• access to Meridian 1 private networking (SL-1 protocol)

BRI services and features

The services and features provided over BRI lines include:

• data transmission at speeds up to 128 kb/s per loop (depending on the bandwidth supported by
your service provider)

• shared digital lines for voice and data ISDN terminal equipment

BCM50 Basic Rate Interface (BRI) also support D-channel packet service between a network and
terminal connection. This allows you to add applications such as point-of-sale terminals (POSTA)
without additional network connections. Connecting a POSTA allows transaction terminals
(devices where you swipe credit or debit cards) to transmit information using the D channel of the
BRI line, while the B channels of the BRI line remain available for voice and data calls. A special
adapter links transaction equipment, such as cash registers, credit card verification rigs, and
point-of-sale terminals, to the X.25 network, which is a data communications network designed to
transmit information in the form of small data packets.

To support the D-packet service, your ISDN network and financial institution must be equipped
with a D-packet handler. To convert the protocol used by the transaction equipment to the X.25
protocol, your ISDN network must also be equipped with an integrated X.25 PAD which works
with the following versions of X.25: Datapac 32011, CCITT, T3POS, ITT and API. The ISDN
service package you order must include D-packet service (for example, Package P in the United
States; Microlink™ with D-channel in Canada).

Your service provider supplies a Terminal Endpoint Identifier (TEI) and DN to support D-packet
service. The TEI is a number between 00 and 63 (in Canada, the default range is 21-63). Your
service provider may also supply you with a DN to program your D-packet device. The DN for
D-packet service becomes part of the dialing string used by the D-packet to call the packet handler.

Service provider features

BCM50 supports the following ISDN services and features offered by ISDN service providers:

• D-channel packet service (BRI only) to support devices such as transaction terminals.
Transaction terminals are used to swipe credit or debit cards and transmit the information to a
financial institution in data packets.

• Calling number identification (appears on both BCM50 sets and ISDN terminal equipment
with the capability to show the information).

• Multiline hunt or DN hunting which switches a call to another ISDN line if the line usually
used by the Network DN is busy (for BRI only).

NN40020-309NN40020-309

Chapter 5 ISDN overview 33

• Subaddressing of terminal equipment (TE) on the same BRI loop. However, terminal
equipment which supports sub-addressing is not commonly available in North America (for
BRI only).

Transmission of B-channel packet data using nailed up trunks is not supported by BCM50.

Contact your ISDN service provider for more information about these services and features. For
more information about ordering ISDN service in North America, see “Ordering ISDN PRI” on

page 39 and “Ordering ISDN BRI” on page 39.

The terminal equipment connected to the BCM50 system can use some feature codes supported by
the ISDN service provider.

Network name display

This feature allows ISDN to deliver the Name information of the users to those who are involved
in a call that is on a public or private network.

Your BCM50 system displays the name of an incoming call when it is available from the service
provider. If the Calling Party Name has the status of private, it appears as
is how the service provider has indicated that it mus appear. If the Calling Party Name is
unavailable it can appear as

Unknown name.

Private name, if that

Your system can display the name of the called party on an outgoing call, if it is provided by your
service provider. Your system sends the Business Name concatenated with the set name on an
outgoing call but only after the Business Name has been programmed.

The available features include:

• Receiving Connected Name

• Receiving Calling Name

• Receiving Redirected Name

• Sending Connected Name

• Sending Calling Party Name

Consult your customer service representative to determine which of these features is compatible
with your service provider.

Name and number blocking

When activated, use FEATURE 819 to block the outgoing name or number (or both) for each call.
Name and number blocking can be used with a BCM50 set.

Note: Name and number blocking is only available in North America.

Consult your customer service representative to determine whether or not this feature is
compatible with your provider.

Telephony Device Installation Guide

34 Chapter 5 ISDN overview

Call by Call Service Selection for PRI

PRI lines can be dynamically allocated to different service types with the Call by Call feature. PRI
lines do not have to be pre-allocated to a given service type. Outgoing calls are routed through a
dedicated PRI Pool and the calls can be routed based on various schedules.

Note: Call by Call Service Selection for PRI is only available in North
America.

The service types that may be available, depending on your service provider are

• Public: Public service calls connect your BCM50 set with a Central Office (CO). DID and
DOD calls are supported.

• Private: Private service calls connect your BCM50 set with a Virtual Private Network. DID and
DOD calls are supported. A private dialing plan may be used.

• TIE: TIE services are private incoming and outgoing services that connect Private Branch
Exchanges (PBX) such as BCM50.

• FX (Foreign Exchange): FX service calls logically connect your BCM50 telephone to a remote
CO. It provides the equivalent of local service at the distant exchange.

• OUTWATS: OUTWATS is for outgoing calls. This allows you to originate calls to telephones
in a specific geographical area called a zone or band. Typically a flat monthly fee is charged
for this service.

• Inwats: Inwats is a type of long distance service which allows you to receive calls originating
within specified areas without a charge to the caller. A toll-free number is assigned to allow for
reversed billing.

Consult your customer service representative to determine whether or not this feature is
compatible with your provider.

Emergency 911 dialing

The ISDN PRI feature is capable of transmitting the telephone number and internal extension
number of a calling station dialing 911 to the Public Switched Telephone Network (PSTN). State
and local requirements for support of Emergency 911 dialing service by Customer Premises
Equipment vary. Consult your local telecommunications service provider regarding compliance
with applicable laws and regulations. For most installations the following configuration rules
should be followed, unless local regulations require a modification.

Note: Emergency 911 dialing is only available in North America.

• All PSTN connections must be over PRI.

• In order for all sets to be reached from a Public Safety Answering Position (PSAP), the system
must be configured for DID access to all sets. In order to reduce confusion, the dial digits for
each set should be configured to correspond to the set extension number.

NN40020-309NN40020-309

Chapter 5 ISDN overview 35

• The OLI digits for each set should be identical to the DID dialed digits for the set.

• The routing table should route 911 to a PRI line pool.

• If attendant notification is required, the routing table must be set up for all 911 calls to use a
dedicated line which has an appearance on the attendant console.

• The actual digit string 911 is not hard-coded into the system. More than one emergency
number can be supported.

If transmission of internal extension numbers is not required or desired, then it is recommended
that the person in charge of the system maintain a site map or location directory that allows
emergency personnel to rapidly locate a BCM50 set given its DID number. This list should be kept
up to date and readily available.

IP telephony note: Ensure that you do not apply a 911 route to an IP telephone that is off the
premises where the PSAP is connected to the system.

Two-way DID

With PRI the same lines can be used for receiving direct inward dialing (DID) and for making
direct outward dialing (DOD) calls.

The dialing plan configured by your customer service representative determines how calls are
routed. Consult your customer service representative to determine whether or not this feature is
compatible with your service provider.

Note: For information on adding integrated lines on an integrated router,
refer to the integrated router documentation.

Dialing plan and PRI

The Dialing Plan supports PRI connectivity to public and private networks. The dialing plan is a
collection of features responsible for processing and routing incoming and outgoing calls. All PRI
calls must go through a dialing plan.

Notes about the dialing plan:

• allows incoming calls to be routed to sets based on service type and digits received

• provides the ability to map user-dialed digits to a service type on a Call by Call basis

• allows long distance carrier selection through user-dialed Carrier Access Codes

Consult your customer service representative to determine how your dialing plan is configured.

Telephony Device Installation Guide

36 Chapter 5 ISDN overview

ISDN hardware

To support connections to an ISDN network and ISDN terminal equipment, your BCM50 must be
equipped with a BRI S/T Media Bay Module (BRIM) or a Digital Trunk Media Bay Module
(DTM) card configured for PRI. The digital BRI ISDN lines are connected to the BCM50b,
BCM50ba, and BCM50be main units through the BRI ports (RJ-45) on the front of the main units.

The following describes the hardware:

• "PRI hardware"

• "BRI hardware"

Note: For information on adding integrated lines on an integrated router,
refer to the integrated router documentation.

PRI hardware

The Digital Trunk Media Bay Module (DTM) is configured for PRI. In most PRI network
configurations, you need one DTM configured as PRI to act as the primary clock reference. The
only time when you cannot have a DTM designated as the PRI primary clock reference is in a
network where your BCM50 system is connected back-to-back with another switch using a PRI
link. If the other switch is loop-timed to your BCM50 system, your DTM (PRI) can be designated
as a timing master.

If your BCM50 has more than one DTM configured as PRI, you must assign the first DTM as the
primary reference, the second DTM as the secondary reference.

If the system has a BRI module, it should be set as the timing master when a DTM in the same
network is defined as the primary reference.

BRI hardware

The loops on the BRI module can be programmed to support either network or terminal
connections. This allows you to customize your arrangement of lines, voice terminals, data
terminals and other ISDN equipment. This section describes some basic hardware configurations
for network and terminal connections for each loop type.

A BRI module provides four loops. Each loop can be individually programmed as one of the
following:

• an S reference point connection (S loop) to ISDN terminal equipment (TE)

• a T reference point connection (T loop) to an ISDN network using an external NT1

You can add integrated BRI lines on the BCM50a, BCM50e, and BCM50ae main units.

S Reference Point

The S reference point connection provides either a point-to-point or point-to-multipoint digital
connection between BCM50 and ISDN terminal equipment (TE) that uses an S interface. Refer to

Figure 8.

NN40020-309NN40020-309

S loops support up to seven ISDN DNs, which identify TE to the BCM50 system.

T Reference Points

The T reference point connections provide a point-to-point digital connection between the ISDN
network and BCM50. Refer to Figure 9.

A T loop provides lines that can be shared by all BCM50 telephones, peripherals and applications,
and ISDN TE.

Figure 9 T reference point

A T loop can be used in combination with an S loop to provide D-packet service for a point-of-sale
terminal adapter (POSTA) or other D-packet device. D-packet service is a 16 kb/s data
transmission service that uses the D-channel of an ISDN line. The T and S loops must be on the
same physical module.

Clock source for ISDN

Systems with ISDN interfaces need to synchronize clocking with the ISDN network and any ISDN
terminal equipment connected to the network. Systems synchronize clocking to the first
functionally available network connection. If there are excessive errors on the reference network
connection, the next available network connection is used for clock synchronization. The clock
synchronization process generates alarm codes and event messages. Clock synchronization is
supported by the DTM, BRI module, and FEM.

The BCM50 derives timing from the network using T reference points (loops). Terminal
equipment on S reference points (loops) derive timing from the BCM50 system.

When you configure the network connections to the BCM50, you should take into account the
system preferences for selecting loops for synchronization:

• lower numbered loops have preference over higher numbered loops

• the loop preference order is: 201, 202, 203, 204 etc.

• the system skips S and analog loops, when selecting a network connection for synchronization

Systems with only S loops act as timing masters for the attached terminal equipment (TE), and are
not synchronized to the network. ISDN TE without access to a network connection (BRI lines) has
limited or no functionality.

If your system has both a BRI S/T configured as BRI, and a DTM configured as PRI, it is
recommended that you use PRI as the primary clock source. See “PRI hardware” on page 36.

ISDN BRI NT1 equipment

The NT1 (network termination type 1) connects an S interface (four-wire) to a U interface
(two-wire). In most cases, it connects loops from a BRI module to the network connection, which
uses the U interface.

The NT1 converts and reformats data so it can be transmitted to and from the S or T connection
(only in North America). In addition, it manages the maintenance messages travelling between the
network and the NT1, and between the NT1 and the BCM50 system.

The NT1 from Nortel is packaged two ways:

• a stand alone package which contains one NT1 card (NTBX80XX) and a power supply
(NTBX81XX)

• a modular package which contains up to 12 NT1 cards (NTBX83XX) and a power supply
(NTBX86AA)

ISDN standards compatibility

In North America, BCM50 ISDN equipment supports National ISDN standards for basic call and
calling line identification services. BCM50 BRI is compliant with National ISDN-1 and PRI is
compliant with National ISDN-2.

BCM50 does not support EKTS (Electronic Key Telephone System) on PRI.

In Europe, BCM50 supports ETSI Euro and ETSI QSIG standards, and PRI SL-1 protocol.

NN40020-309NN40020-309

Planning your ISDN network

For ISDN BRI service, your service provider supplies service profile identifiers (SPIDs), network
directory numbers (Network DNs), terminal endpoint identifiers (TEIs), and other information as
required to program your BCM50, TE and other ISDN equipment.

BCM50 does not support any package with EKTS or CACH. EKTS is a package of features
provided by the service provider and may include features such as Call Forwarding, Link,
Three-Way Calling, and Calling Party Identification.

Ordering ISDN PRI

This section provides information about how to order ISDN PRI service for your BCM50.

Ordering ISDN PRI service in Canada

Ordering ISDN PRI service in the Canada/United States from your service provider. Set the
BCM50 equipment to the PRI protocol indicated by your service provider.

Ordering ISDN PRI service outside of Canada and the United States

Chapter 5 ISDN overview 39

Outside of Canada and the United States order Euro ISDN PRI and/or BRI service from your

Ordering ISDN BRI

The following provides information about how to order ISDN BRI service for your BCM50.

Ordering ISDN BRI service in Canada

In Canada, order Microlink service, the trade name for standard BRI service. You can order either
regular Microlink service, which includes the CLID feature, or Centrex Microlink, which includes
access to additional ISDN network features, including Call Forwarding.

When ordering Microlink service, you must order it with EKTS turned off. If you are using a
point-of-sale terminal adapter (POSTA), ask for D-packet service to be enabled.

Ordering ISDN BRI service in the United States

In the United States, regardless of the CO (Central Office) type, order National ISDN BRI-NI-2
with EKTS (Electronic Key Telephone System) turned off. Use the following packages as a
guideline for ordering your National ISDN BRI-NI-2. However, we recommend using packages
M or P with the BCM50 system. Contact your service provider for more information about the

connects the call to another telephone number in the group. BCM50 supports the feature only on
point-to-point, network connections (T loop). Check with your service provider for more
information about Multi-Line Hunt.

Any of the ISDN packages will allow you to use sub-addressing, but your ISDN TE must be
equipped to use sub-addressing for the feature to work.

Ordering ISDN BRI service outside Canada or the United States

Outside of Canada or the United States order Euro ISDN PRI and/or BRI service from your service
provider. Set the BCM50 equipment to the Euro ISDN protocol.

Supported ISDN protocols

The switch used by your service provider must be running the appropriate protocol software and
the correct version of that software to support ISDN PRI and BRI. Each protocol is different and
supports different services. Contact your service provider to make sure that your ISDN connection
has the protocol you require.

Chapter 6

IP telephone overview

IP telephony provides the flexibility, affordability, and expandability of the Internet to the world of
voice communications.

This section includes an overview of the components that make up the BCM50 2.0 IP telephony
and Voice over IP (VoIP) features:

• “IP telephones and VoIP trunks” on page 42

• “Creating the IP telephony network” on page 42

• “Key IP telephony concepts” on page 46

BCM50 2.0 with VoIP provides several critical advantages:

• Cost Savings. IP networks can be significantly less expensive to operate and maintain than
traditional networks. The simplified network infrastructure of an Internet Telephony solution
cuts costs by connecting IP telephones over your LAN and eliminates the need for dual
cabling. Internet Telephony can also eliminate toll charges on site-to-site calls by using your
existing IP network. By using the extra bandwidth on your IP network for IP Telephony, you
leverage the untapped capabilities of your data infrastructure to maximize the return on your
current network investment.

• Cost flexibility. The three models of IP telephones offer three levels of functionality, that
allow you to choose an IP telephone that fits your budget and/or your service requirements.

• Portability and flexibility. Employees can be more productive because they are no longer
confined by geographic location. IP telephones work anywhere on the network, even over a
remote connection. With Nortel wireless e-mobility solutions, your phone, laptop, or scanner
can work anywhere on the network where a an 802.11b access point is installed. Network
deployments and reconfigurations are simplified, and service can be extended to remote sites
and home offices over cost-effective IP links. As well, IP telephone functionality can be
transferred between IP telephones using the Hot desking feature. All your telephone features
and setup can travel with you between offices.

• Simplicity and consistency. A common approach to service deployment allows further
cost-savings from the use of common management tools, resource directories, flow-through
provisioning, and a consistent approach to network security. As well, customers can centrally
manage a host of multimedia services and business-building applications via a Web-based
browser. The ability to network existing PBXs using IP can bring new benefits to your
business. For example, the ability to consolidate voice mail onto a single system, or to fewer
systems, makes it easier for voice mail users to network.

• Compatibility. Internet telephony is supported over a wide variety of transport technologies.
A user can gain access to just about any business system through an analog line, Digital
Subscriber Line (DSL), a LAN, frame relay, asynchronous transfer mode, SONET, or wireless
connection.

42 Chapter 6 IP telephone overview

• Scalability. A future-proof, flexible, and safe solution, combined with high reliability, allows
your company to focus on customer needs, not network problems. Nortel internet telephony
solutions offer hybrid environments that leverage existing investments in Meridian and Norstar
systems.

• Increased customer satisfaction. Breakthrough e-business applications help deliver the
top-flight customer service that leads to success. By providing your customers with rapid
access to sales and support personnel via telephone, the Web, and e-mail, your business can
provide better customer service than ever before.

IP telephones and VoIP trunks

This section describes two similar applications for IP telephony on the BCM50 2.0 system: IP
telephones and VoIP trunks. These applications can be used separately or together as a network
voice/data solution.

Refer to the information under the following headings:

• "IP telephones"

• "VoIP trunks"

IP telephones

IP telephones offer the functionality of regular telephones, but do not require a hardwire
connection to the BCM50 2.0. Instead, they must be plugged into an IP network which is
connected to the through the integrated interface (LAN card) on the BCM50 2.0.

Calls made from IP telephones through the BCM50 2.0 can pass over VoIP trunks or across Public
Switched Telephone Network (PSTN) lines.

Nortel provides two types of IP telephones. The IP telephones are wired to the IP network using
Ethernet, in the case of the IP Phone series of telephones, or are accessed through your desktop or
laptop computer, as in the case of the IP Software Phone 2050.

VoIP trunks

VoIP trunks allow voice signals to travel across IP networks. A gateway within the BCM50 2.0
converts the voice signal into IP packets, which are then transmitted through the IP network to a
gateway on the remote system. The device at the other end reassembles the packets into a voice
signal. H.323 trunks support private networking between BCM50 2.0s. H.323 trunks can support
connections to a number of different types of equipment, including the Meridian 1 (running IPT),
Succession 1000/M, DMS100 switches, and SL100 switches, and trunk applications.

Creating the IP telephony network

The following explains the components of the BCM50 2.0 system and the devices it interoperates
to create a network.

NN40020-309NN40020-309

Chapter 6 IP telephone overview 43

The information under the following headings describes the various components of the system:

• “M1-IPT” on page 45

• “Telephones” on page 45

• “Gatekeepers on the network” on page 45

• “IP network” on page 46

• “Public Switched Telephone Network” on page 46

Figure 10 shows components of a BCM50 2.0 network configuration.

In this example, two BCM50 2.0 systems are connected both through a PSTN connection and
through an IP network connection. The IP network connection uses VoIP trunks. If the PSTN
connections use dedicated ISDN lines, the two systems have backup private networks to each
other. Both BCM50 2.0 systems use VoIP trunks through a common IP network to connect to the
Meridian (M1-IPT) system.

Networking with BCM50 2.0

The BCM50 2.0 is a key building block in creating your communications network. It interoperates
with many devices, including the Meridian 1 system and H.323 devices. The BCM50 2.0 system
can be connected to devices through multiple IP networks, as well as through the PSTN. Multiple
BCM50 2.0 systems also can be linked together on a network of VoIP trunks and/or dedicated
physical lines.

The BCM50 2.0 can be connected to a LAN through a the integrated interface LAN card, and to a
PSTN through trunk media bay modules, as shown for BCM50 2.0 A in Figure 10. Through these
networks, the system accesses other systems and network equipment connected to the network.

H.323 Device B

IP telephone B

NN40020-309NN40020-309

Chapter 6 IP telephone overview 45

M1-IPT

The Meridian 1 Internet Telephony Path (M1-IPT) allows Meridian 1 systems to communicate
with the BCM50 2.0 via H.323 trunks. Telephones on the M1, such as Meridian telephone A, can
initiate and receive calls with the other telephones on the system across IP networks.

To provide fallback at times when IP traffic cannot pass, you can also connect the Meridian to the
BCM50 2.0s through ISDN PRI SL-1 lines, which provide the same MCDN capability that you
can achieve through the H.323 VoIP trunks with MCDN active.

A BCM50 2.0 connected to an M1-IPT using the MCDN protocol can provide access to a central
voice mail and call attendant systems, which can streamline multi-office telephony administration.

Telephones

The BCM50 2.0 can communicate using digital telephones (Model 7000, 7100, 7208, 7316,
7316E/7316E+KIMs, 7406 (cordless telephone), Norstar M-series telephones, ISDN telephones,
analog telephones, and IP telephones and applications. With this much flexibility, the BCM50 2.0
can provide the type of service you require to be most productive in your business.

While analog and digital telephones cannot be connected to the BCM50 2.0 system with an IP
connection, they can make and receive calls to and from other systems through VoIP trunks. Calls
received through the VoIP trunks to system telephones are received through the integrated
interface (LAN card) or the IP network and are translated within the BCM50 2.0 to voice channels.

The IP telephones connect to the BCM50 2.0 across an IP network through either a LAN or a
WAN. From the BCM50 2.0 connection, they can then use standard lines or VoIP trunks to
communicate to other telephones on other public or private networks. The BCM50 2.0 also
supports H.323 (version 4) and H.323 third-party devices through this type of connection.

Gatekeepers on the network

A gatekeeper tracks IP addresses of specified devices, and provides routing and (optionally)
authorization for making and accepting calls for these devices. A gatekeeper is not required as part
of the network to which your BCM50 2.0 system is attached, but gatekeepers can be useful on
networks with a large number of devices. Referring to Figure 10, for example: Digital telephone A
wants to call IP telephone B, which is attached to BCM50 2.0 B, over a network that is under the
control of a gatekeeper. Digital telephone A sends a request to the gatekeeper. The gatekeeper,
depending on how it is programmed, provides Digital telephone A with the information it needs to
contact BCM50 2.0 B over the network. BCM50 2.0 B then passes the call to IP telephone B.

The BCM50 2.0 does not contain a gatekeeper application. If you want to put a gatekeeper on your
network, it must be put on a separate gatekeeper server. The BCM50 2.0 is compatible with
CS1000 (CSE1K) gatekeepers.

Warning: Meridian 1 IPT does not support the RadVision gatekeeper.

Telephony Device Installation Guide

46 Chapter 6 IP telephone overview

IP network

In the network shown in Figure 10, several LANs and a WAN are shown. When planning your
network, be sure to consider all requirements for a data network. Your network administrator
should be able to advise you about the network setup and how the BCM50 2.0 fits into the
network.

WAN

A Wide Area Network (WAN) is a communications network that covers a wide geographic area,
such as state or country. For BCM50 2.0, a WAN is any IP network connected to a WAN card on
the BCM50 2.0 system. This may also be a direct connection to another BCM50 2.0 system.

If you want to deploy IP telephones that will be connected to a LAN outside of the LAN that the
BCM50 2.0 is installed on, you must ensure the BCM50 2.0 is able to communicate across the
WAN interface at that location.

LAN

A Local Area Network (LAN) is a communications network that serves users within a confined
geographical area. For BCM50 2.0, a LAN is any IP network connected to the integrated interface
(a LAN card) on the BCM50 2.0 system. Often, the LAN can include a router that forms a
connection to the Internet. A BCM50 2.0 can have up to two LAN connections.

Public Switched Telephone Network

The Public Switched Telephone Network (PSTN) can play an important role in IP telephony
communications. In many installations, the PSTN forms a fallback route. If a call across a VoIP
trunk does not have adequate voice quality, the call can be routed across PSTN lines instead, either
on public lines or on a dedicated ISDN connection between the two systems (private network).
The BCM50 2.0 also serves as a gateway to the PSTN for all voice traffic on the system.

Key IP telephony concepts

In traditional telephony, the voice path between two telephones is circuit switched. This means
that the analog or digital connection between the two telephones is dedicated to the call. The voice
quality is usually excellent, since there is no other signal to interfere.

In IP telephony, each IP telephone encodes the speech at the handset microphone into small data
packets called frames. The system sends the frames across the IP network to the other telephone,
where the frames are decoded and played at the handset receiver. If some of the frames get lost
while in transit, or are delayed too long, the receiving telephone experiences poor voice quality.
On a properly-configured network, voice quality should be consistent for all IP calls.

NN40020-309NN40020-309

Chapter 6 IP telephone overview 47

The information under the following headings describes some of the components that determine
voice quality for IP telephones and trunks:

• “Codecs” on page 47

• “Jitter buffer” on page 47

• “QoS routing” on page 48

Codecs

The algorithm used to compress and decompress voice is embedded in a software entity called a
codec (COde-DECode).

Two popular Codecs are G.711 and G.729. The G.711 Codec samples voice at 64 kilobits per
second (kb/s) while G.729 samples at a far lower rate of 8 kb/s.

Voice quality is better when using a G.711 Codec, but more network bandwidth is used to
exchange the voice frames between the telephones.

If you experience poor voice quality, and suspect it is due to heavy network traffic, you can get
better voice quality by configuring the IP telephone to use a G.729 Codec.

Note: You can only change the codec on a configured IP telephone if it is online
to the BCM50 2.0, or if Keep DN Alive is enabled for an offline telephone.

The BCM50 2.0 supports these codecs:

•G.729

•G.723

• G.729 with VAD (Voice Activity Detection)

• G.723 with VAD

•G.711-uLaw

•G.711-aLaw

Jitter buffer

Voice frames are transmitted at a fixed rate, because the time interval between frames is constant.
If the frames arrive at the other end at the same rate, voice quality is perceived as good. In many
cases, however, some frames can arrive slightly faster or slower than the other frames. This is
called jitter, and degrades the perceived voice quality. To minimize this problem, configure the IP
telephone with a jitter buffer for arriving frames.

Note: You can only change the jitter buffer on a configured IP telephone if it is
online to the BCM50 2.0, or if Keep DN Alive is enabled for an offline telephone.

Telephony Device Installation Guide

48 Chapter 6 IP telephone overview

This is how the jitter buffer works:

Assume a jitter buffer setting of five frames.

• The IP telephone firmware places the first five arriving frames in the jitter buffer.

• When frame six arrives, the IP telephone firmware places it in the buffer, and sends frame one
to the handset speaker.

• When frame seven arrives, the IP telephone buffers it, and sends frame two to the handset
speaker.

The net effect of using a jitter buffer is that the arriving packets are delayed slightly in order to
ensure a constant rate of arriving frames at the handset speaker.

This delaying of packets can provide somewhat of a communications challenge, as speech is
delayed by the number of frames in the buffer. For one-sided conversations, there are no issues.
However, for two-sided conversations, where one party tries to interrupt the other speaking party,
it can be annoying. In this second situation, by the time the voice of the interrupter reaches the
interruptee, the interruptee has spoken (2*jitter size) frames past the intended point of interruption.
In cases where very large jitter sizes are used, some users revert to saying OVER when they wish
the other party to speak.

Possible jitter buffer settings, and corresponding voice packet latency (delay) for the BCM50 2.0
system IP telephones are:

•None

• Small (G.711/G.729: 0.05 seconds)

• Medium (G.711/G.729: 0.09 seconds)

• Large (G.711/G.729: 0.15 seconds)

QoS routing

To minimize voice jitter over low bandwidth connections, the BCM50 2.0 programming assigns
specific DiffServ Marking in the IPv4 header of the data packets sent from IP telephones and from
IP trunks.

The DiffServ Code point (DSCP) is contained in the second byte of the IPv4 header. DSCP is used
by the router to determine how the packets will be separated for Per Hop Behavior (PHB). The
DSCP is contained within the DiffServ field, which was known as the ToS field in older versions.
The BCM50 2.0 assigns Expedited Forwarding (EF) PHB for voice media packets. On the BCM50

2.0, these assignments cannot be adjusted.

Registering Nortel 20XX and 11XX IP telephones

The Nortel IP telephones must register with the system to be able to use the call features and
system features.

Determining the registration process

Registering IP telephones to the system is a two-stage process.

Note: Ensure that you have loaded the appropriate keycodes to activate
the Nortel IP telephones on your BCM50 system.

1 Set up the system programming to receive registration under Resources > Telephony

Resources > IP Terminal Global Settings tab.

49

On the Global Settings panel:

a Select the Enable registration check box.

b If you want the installers to use a single password to configure and register the telephone,

select the Enable global registration password check box, and then enter a numeric
password in the Global password field.

c If you want the system to automatically assign DN records to the telephones, select the

Auto-assign DNs check box.

Note: To automatically configure IP Phones with DNs assigned:

1) Select the Enable registration check box.

2) Select the Enable global registration password check box.

3) Leave Global password field blank.

4) Select the Auto-assign DNs check box.

Once the IP Phones are operational, clear the Enable
registration check box.

Security Note: Turn Enable registration and Auto-assign DNs off when the
telephones are registered. Nortel cautions that leaving your IP registration open and
unprotected by a password can pose a security risk.

2 Configure each telephone (“Configuring telephone settings” on page 50).

How you configure the telephones depends on whether DHCP is active on the system.

Telephony Device Installation Guide

50 Chapter 7 Registering Nortel 20XX and 11XX IP telephones

— If DHCP (Distributed Host Control Protocol) service on the system is active or the

Customer DHCP server has been configured to hand out the specific system network
details, the IP telephone automatically attempts to find the server.

After you register the telephone to the system, as described in “Registering the telephone

to the system” on page 50, the telephone assumes the parameters it receives from the

system, which are described in “Configuring telephone settings” on page 50).

— If DHCP is not configured to provide system information, or if you are not using DHCP on

your network, you must configure your telephone parameters before the telephone can
register to the system. In this case, follow the directions in “Configuring telephone

settings” on page 50, and then follow any of the prompts that appear, as described in
“Registering the telephone to the system” on page 50.

— If an external DHCP server is not present, the DHCP server on the main unit supplies IP

configuration information for all IP devices (PCs and IP Phones). It also supplies specific
connection information to the IP Phones.

Registering the telephone to the system

When you first connect the telephone to the IP connection, you receive one of the following:

• If the telephone is not yet registered, and when a password is entered in the Terminal
Registration screen, the telephone prompts you for that password.

• If Auto Assign DN is not selected, the telephone prompts you for a DN. Refer to the Device
Configuration Guide (NN40020-300) for more information on configuring telephones.

• If you are prompted for a password, enter the password and press OK.

• If you are prompted for a DN, enter the DN you want assigned to this telephone and press OK.

When the telephone registers, it downloads the information from the system IP Telephony record
to the telephone configuration record. This can include a new firmware download, which occurs
automatically. If new firmware downloads, the telephone display indicates the event.

Note: If the telephone displays a prompt that indicates it cannot find the server, follow
the instructions in “Configuring telephone settings” on page 50 to enter the specific
network path. “Troubleshooting IP telephones” on page 55 describes other possible
prompt messages.

Configuring telephone settings

If you are not automatically registered to the system, you can configure the telephone settings to
enable you to access a system on the network. You also must perform these steps if your
IP telephone is not connected to the same LAN to which the system is connected.

within two minutes after power up, the telephone did not establish
communications with the system. Double-check the IP configuration of the
telephone and the IP connectivity to the system (cables, hubs, and so on).

If the connection between the IP client and the system is slow (ISDN, dialup
modem), change the preferred CODEC for the telephone from G.711 to G.729.
See Ta b le 4 .

Signaling between the IP telephones and the system uses the system port

7000. However, voice packets are exchanged using the default RTP ports
28000 through 28255 at the BCM50, and ports 51000 through 51200 at the IP
telephones. If these ports are blocked by the firewall or NAT, you will
experience one-way or no-way speech paths.

When an IP telephone is connected for the first time, the contrast level is set to
the default setting of 1. Use FEATURE *7 and the

If you want to block one or more IP telephones from calling outside the system,
use Restriction filters, and assign them to the telephones you want to block.

Chapter 8

Relocating telephones

This chapter explains how you can physically move a telephone within the system so that the
telephone programming follows the telephone to the new location.

• “Moving digital telephones” on page 59

• “Moving IP telephones” on page 60

• “User card list” on page 61 provides a list of the user cards for individual types of telephones

Moving digital telephones

To move a digital telephone to a new location within the system so that the programmed settings
are retained, set relocation (automatic telephone relocation) must be enabled in system
programming. Set relocation saves the internal numbers, autodial settings, and personal speed dial
codes within the telephone when the telephone is unplugged.

59

Note: The set relocation feature applies to the digital telephones and analog telephones,

only. IP telephones always retain their programming. Refer to “Moving IP telephones” on

page 60.

Tips (if set relocation is enabled)

Relocate existing telephones before new telephones are installed on the jacks. This allows
the moved telephones to retain their programming.

Plugging a new telephone into a jack from which another telephone was removed, before
the original telephone is reconnected to another jack, results in the programming
transferring to the new telephone. In this case, when the original telephone is plugged into
another jack, it receives default programming, or the programming specifically entered for
the DN record that corresponds to the new jack.

When changing a telephone internal number (DN record), wait one minute for automatic
telephone relocation to complete its cycle. When you relocate a telephone, the telephone
must remain installed and connected in the new location for at least three minutes for the
programming relocation to be complete. Moving the telephone again before the
three-minute period is up can result in loss of programming.

Telephony Device Installation Guide

60 Chapter 8 Relocating telephones

To enable set relocation and to relocate digital telephones

1 In the Element Manager, go to Configuration > Telephony > Global Settings > Feature

Settings.

The Feature Settings panel appears.

2 In the Feature Settings area, select the Set relocation check box.

3 Move the telephone by physically unplugging the telephone and plugging it in again at another

location.

It can take up to 45 seconds for the system to recognize the telephone.

4 Clear the Set relocation check box.

Keeping an IP telephone active

In some circumstances, you may want to have your IP telephone stay active after it is physically
disconnected. For example, when your IP Software Phone 2050 is turned off, you may still want
callers to go to your voicemail. To keep your IP telephone active and retain DN-specific features,
activate the Keep DN alive feature.

To keep an IP telephone active after it is disconnected

1 In the Element Manager, go to Configuration > Telephony > Sets > Active Sets.

2 Click the Capabilities and Preferences tab.

3 Click IP Terminal details.

4 Select the Keep DN alive check box.

Note: Clear the check box to allow the DN record to become inactive if

the IP telephone is disconnected.

Moving IP telephones

IP telephones retain their DN when you move them to a new location on the same subnet. The
following instructions apply to Nortel IP telephones.

To move an IP telephone without changing the DN

1 Disconnect the power from the IP telephone or three-port switch.

2 Disconnect the network connection.

3 At the new location, reconnect the network cable and the power connection.

NN40020-309NN40020-309

4 If the new location is on a different subnet, you must make the appropriate changes to the

telephone IP addressing. However, do not change the S1 IP address or the S2 IP address.
Disconnect the power from the IP telephone or three-port switch.

Note: If your network is using partial DHCP, reconfiguration is not required at
this step.

To move a Nortel IP telephone and change the DN

1 Deregister the DN.

2 Disconnect the network connection and the power connection from the telephone.

3 Reinstall the telephone at the new location, and reconfigure the telephone.
