System Overview
20 Chapter 2 System Overview
BCM50 features
BCM50 features are summarized in two sections, "New features" and “Existing features” on page
29.
New features
The following list indicates the new features introduced with BCM50 3.0.
• “Software upgrade” on page 20
• “SIP trunk enhancements” on page 21
• “IP phone 1200” on page 22
• “IP phone 1110” on page 22
• “Meet-Me Conferencing” on page 22

• “Intelligent Contact Center” on page 24
• “Activity Reporter” on page 25
• “Operability enhancements” on page 26
• “Security enhancements” on page 26
• “Microsoft Vista operating system” on page 27
Software upgrade
The upgrade impacts all on-box software of a field installed BCM50 1.0 or BCM50 2.0 system to
BCM50 3.0 software while preserving customer programmed data. New software introduced as
part of the BCM50 3.0 program is installed as part of the upgrade. An upgraded BCM50 3.0
system is functionally equivalent to a factory BCM50 3.0 system. The target time for an upgrade is
45 minutes.
The upgrade with BCM50 and Business Element Manager supports remote and scheduled
upgrades. This new capacity is significant for partners and administrators to reduce installation
costs and business impacts. Systems that operate in SRG mode are upgraded to the new software
but remain in SRG mode after the upgrade.
Support exists for the following upgrade paths:
• BCM50 1.0 to BCM50 3.0
• BCM50 2.0 to BCM50 3.0
• BCM50 1.0 to BCM50 2.0 to BCM50 3.0
NN40020-200
System Overview Chapter 2 21
SIP trunk enhancements
SIP REFER
BCM50 3.0 supports SIP REFER, which is the call transfer mechanism for SIP. BCM50 responds
to a REFER request on an existing call by making a second call and transferring the two calls
together. BCM also responds to a REPLACE request on an incoming call by replacing the
identified incoming SIP call with this new call.
SIP refer supports two types of call transfer:
• Blind (or Unattended): The TransferOR puts the primary call on hold, then dials the
Transfer Target and completes the transfer without communicating with the Transfer
Target. The TransferEE hears ringback on the secondary call and connects when the
Transfer Target answers.
• Consult (or Attended): The TransferOR places the primary call on hold and establishes a
Consult call (consultation) to another party. After the consultation, the TransferOR
completes the transfer, causing the TransferEE to connect to the Transfer Target and
replaces the Transfer Target's call with the TransferOR.
SIP proxy failover
A new setting, called Route all calls using proxy, on the SIP Proxy tab in the Business Element
Manager, determines whether to ignore the Routing Table for SIP calls. With SIP proxy failover,
the SIP Proxy configuration is used. The SIP Proxy Domain is mandatory and is used in SIP
message headers.
A dedicated SIP Proxy Agent provides outbound proxy failover. The SIP Proxy Agent runs within
the SIP Component of the FEPS process on the BCM.
To provide an alternative call route to a destination, the SIP Proxy Agent interacts with the
Functional Endpoint Proxy Server (FEPS) during outgoing SIP trunk call setup. When proxy
failover provides no on-demand SIP proxy information, the SIP Proxy Agent interacts with the SIP
facilities within the FEPS to periodically poll each configured SIP proxy server to maintain the up
or down status of each server.
RFC 2833
With RFC 2833 the BCM SIP gateway can send and receive Dual-Tone Multi Frequency (DTMF)
digits on SIP trunks using RFC 2833. This feature does not apply to H.323.
For outgoing digits received, the core software enters the digits as DTMF. The Digital Signal
Processor (DSP) intercepts the digits and encodes and them as described in RFC 2833. This is
required in both short- and long-tone mode whenever the media path goes through the BCM.
When the media path does not go through the BCM, the short tone digits are sent to Functional
Endpoint Proxy Server (FEPS) in VDI messages.
For incoming digits, the core software handles incoming digit indications from FEPS and provides
short-tone functionality. While the digits received can be longer than the short-tone duration, the
long duration is not required.
System Overview
22 Chapter 2 System Overview
SIP trunk authentication
SIP trunk local users are accounts used to authorize remote SIP entities when they attempt to
connect through the SIP trunk interface to place calls through the BCM. SIP trunk accounts are
also used for remote connections to the ISP and incoming call requests. The total number of SIP
trunk accounts is 240.
Configuration of domain and ports for remote SIP trunk endpoints
Configuration and use of domain and port entries for remote endpoints allows more flexible
installations, compared to the BCM 4.0 and BCM50 R2 use of IP addresses only. The BCM50 3.0
introduces RFC3263-based DNS support for locating SIP servers. The addition of DNS support
means that customers do not need to know the IP addresses of those remote servers.Standards
based DNS support using RFC3263 to simplify network deployment.
Optional G.711 based transport of FAX communication
This solution will allow the choice of whether T.38 or G.711 is used to transmit fax calls over SIP
trunks, to and from the BCM. The choice is decided during configuration, an d applies to all SIP
trunk calls
If T.38 is not configured, then SuperG3 fax and V.34 modem will be supported over G.711.
Previously, they had to use G3/V.17 in case there was a switch to T.38 which cannot encode V.34
successfully.
IP phone 1200
BCM50 3.0 supports new IP Phone 1200 series and associated expansion modules.
IP phone 1110
BCM50 3.0 supports new IP Phone1110 and associated expansio n module.
Meet-Me Conferencing
Meet-Me Conferencing provides feature-rich, high density conferencing capabilities for BCM
users. Designed to provide a more sophisticated feature set for formal conference calls, Meet-Me
Conferencing allows parties to establish a teleconference by calling in to a specified bridge
number at an agreed on time. One party acts as the chairperson and has additional powers to start,
stop, secure and control the conference.
Conferences are initiated by calling in to the system on designated lines or to a specified directory
number. The service responds by prompting the caller for the conference ID and optional
pass-code. The caller then receives music-on-hold until the chairperson starts the conference. At
that point, a multi way voice conference is established with all parties in the conference.
NN40020-200
System Overview Chapter 2 23
Meet-Me Conferencing supports DTMF-based commands and display/softkey based commands,
so all users, regardless of phone, have access to participant and chairperson controls. All parties
can use DTMF-based commands to control their participation (example: mute on or off). When
using DTMF-based commands, the help menu will provide an audible list of existing commands.
Additionally, the system will provide voice prompts to assist the user. For example, when a user
turns on the mute feature, they will receive a voice prompt saying, muted. When they turn off the
mute feature, a voice prompt will say, un-muted.
Display set users receive status information by way of the display. Softkey equivalents are offered
to softkey-set users.
Status display and softkeys for internal participants include the following:
• status shows elapsed time, number of participants
• VIEW softkey cycles through list of participants, showing name (internal) or CallerID
(external)
• command to turn on or off the mute line
Chairperson commands include the following:
• turn conference mute on or off. While the conference is muted, only the chairperson can
speak
• selectively mute or disconnect a participant with VIEW
• lock or unlock a conference. While locked, no new participants can join conference.
• change continuation or announcement settings
• all participant commands (self-mute on or off, participant count, list commands)
The Meet-Me Conferencing feature supports 18 active ports spread over as many conferences
sessions as desired. Note that the pool of conference ports is shared between Meet-Me
Conferencing and the ad-hoc conference feature. Since the total pool of ports is 18, this means that
if 18 ports are in use for Meet-Me Conferencing, there will be no available ports for ad-hoc
conferences. Similarly, if 18 ports are being used for ad-hoc conferences, there will be no ports
available for Meet-Me Conferences.
Silent Record-a-call
Intelligent Contact Center Agent and Supervisor ad hoc silent record a call. This enables an agent
or supervisor to silently record the call they are on. The recorded call is left in the agents/
supervisors mailbox or skillset mailbox.
This feature does not provide the ability for a supervisor to trigger silent call recording while
listening in on an agent's call.
System Overview
24 Chapter 2 System Overview
Intelligent Contact Center
Intelligent Contact Center API's
Enhanced Intelligent Contact Center API's are included providing more flexibility and
functionality enabling 3rd party applications, like CRM adaptors, to more effectively integrate
with the BCM50 Intelligent Contact Center. The API's are:
• Agent log in,
• Agent log out,
• Not ready
For more information on ICC and the existing features, see “Intelligent Contact Center” on page
51.
Not Ready Time Out
Previous to this release, when a call is presented to an agent and is not answered, the call is
returned to the skillset queue and the agents set is placed into the not ready mode. The agent
receives a visual indication that they are placed into the not ready mode and no further calls are
presented to the agent until they manually take themselves out of the not ready mode. This
enhancement provides an administrable timer that when the timer has expired the agent will be
made active and receive calls. The agent does not have to manually make themselves available.
Not Ready Audible Notification
When an agents is placed into the Not Ready Mode the agent receives an audible and visual
reminder that they are in the not ready mode. This is an enhancement to BCM50 2.0 where only a
visual reminder is provided.
Agent Break Time Configurable on Agent Basis
This enhancement allows the Agent Break (wrap time) Time to be configurable on an agent by
agent basis. The Agent Break Time, is the time that the agent is automatically taken out of the
skillset after completion of a call. Typically, this time is required to complete paper or other
activities associated with the call. Currently Agent Break Time is only configurable on a skillset
basis. This provides more flexibility to call centre manager enabling individual agents to have
different break times based on their experience and or other needs.
Primary and Secondary Alerts Configurable on a Skillset Basis
Primary and Secondary Alerts are now configurable on a skillset by skillset basis. Primary and
Secondary Alerts provide visual indication when calls have been waiting beyond specific
thresholds to agents and supervisors. In BCM50 2.0 the Primary and Secondary Alerts are
configurable on a system wide basis, not on a skillset basis. The enhanced capability provides
more flexibility for the Intelligent Contact Center manager as each skillset can have different
Primary and Secondary Alerts based the characteristics of the skillsets. For some skillsets it may
be acceptable to expect and tolerate longer wait times then others. As such the Primary and
Secondary Alerts can be established specifically for each skillset.
NN40020-200
System Overview Chapter 2 25
Reporting for Contact Center
There are many enhancements to the Reporting for Contact Center included in BCM50 3.0. These
include additional information to existing reports, more flexibility in how reports are generated
and a new Call Audit that provides a complete view of everything that occurs on a call from the
moment it arrives in the Contact Center until it leaves. These enhancements include:
Call Audit Report
• This is a new 'cradle to grave' report
Answered Call Report
• New report that reports CLID and DNIS of answered calls
Agent Audit Report
• New ringing and not available fields
Abandon Call Report
• Added DNIS and Skillset fields
Agent Activity Report
• Added available time, not available time and ringing time fields
Agent Average Report
• Added internal transactions, non CC transactions, not ready time, not available time,
ringing time and supervisor monitoring time
Agent Capacity Report
• More granularity
• Breaks down the instances and time based on each time all agents are busy
Agent Profile Report
• Can now report on multiple skillsets,
• Added not available time, ringing time, supervisor monitoring time, internal transactions
and non CC transactions
Real Time reports
• Added new agent states; ringing and not available
New Agent selection method
• Greater flexibility in what agents reports will be reporting on and allows Agent Reports to
be generated by individual agents as well as skillsets.
Activity Reporter
For information about the Activity Reporter and Activity Reporter Basic features, see the Activity
Reporter Administration Guide and the Activity Reporter User Guide.
System Overview
26 Chapter 2 System Overview
Operability enhancements
Power On Self Test logging
Power On Self Test (POST) is a set of hardware tests occurs early in the system boot cycle. The
data from these tests will be captured and published to the standard log system when the boot cycle
is complete. When there is failure from POST, alarms and SNMP traps will be raised through
existing DiaLogger component.
When BCM 50 is powered up, it goes through a number of POST to validate the system. Results
from the POST are currently displayed on the serial port in real time. If there are any failures, the
results are also captured on Flash. It is desired to capture all POST results, whether they are passed
or failed, so that all results can be displayed at a later time for analysis.
The solution provided here is a complete solution for making POST results available on the main
file system.
IP Music enhancements
The volume normalized enhancement resolves issues where the on hold play back volume is too
loud and can not be adjusted.
The multiple files upload feature enhancement allows customers to upload multiple music files in
a compressed format.
The files preservation over upgrade enhancement resolves issues where music files are not
preserved over upgrade, specially important for professional music recordings.
Business Element Manager change tracking logs
Bring back the tracking changes log that was available on BCM 3.x this log was very useful in
validating and checking steps that lead up to a failure and also validated the steps the installer took
to get in to the configuration problem. This log tracked all changes that had been applied to the
system since it was initialized. The log records the entire configuration steps, not just the final
result.
System ID field copy
This feature allows you to copy the System ID field from the Element Manager to your PC clip
board, and can then paste it directly into the KRS web tool interface. By implementing this simple
ease-of-use functionality, you can remove the human error in querying, downloading and applying
the wrong keycode file to a system that will impact the installation time. Also, this can help to
prevent the case of applying the new authorization code to the wrong system ID and generate the
wrong keycode which can only be reset by Nortel support which impacts installation time,
potential miss customer delivery of system, and cost of ownership.
Security enhancements
In addition to the enhancements mentioned in “SIP trunk authentication” on page 22, BCM50 3.0
includes these new security enhancements.
NN40020-200
System Overview Chapter 2 27
Last failed login time
The last failed login time information is added to the current user panel in BEM and displays the
last time the login was attempted and failed.
Web access on Secure Socket Layer Version 3
BCM50 3.0 sets the default Secure Socket Layer (SSL) protocol to SSLv3 for Web access.
Platform accounts
Platform accounts are integrated accounts that allow access to BEM and other functions based on
privileges. The maximum number of accounts is increased to 280 active accounts for each BCM.
User ID length
The maximum character length for the user ID is 128 characters.

VPN exceptions
The Nortel VPN Client for Vista has the following limitations:
• The Nortel VPN Client must be run as an administrator. UAC always prompt for elevation
when it runs.
NN40020-200
System Overview Chapter 2 29
• The VPN Client installs and runs only as an application. This is due to Vista services
hardening and the deprecation of the GINA infrastructure.
• Support exists only UDP encapsulation. This is due to changes in the Microsoft stack, which
prevents ESP packets from reaching the VPN driver as it is currently implemented. Enable
UDP encapsulation in the Contivity switch group profile. For Vista users, the NAT Traversal
setting must have any value other than Not Allowed.
Unified Messaging Client exceptions

Hardware inventory
As part of the BCM50 management changes, the Business Element Mana ger hardware inventory
panel and the Entity MIB allow you to remotely view detailed information about the CSC,
integrated router, and integrated BRI CDC hardware. Additionally, visibility of other FRU
components, such as fans, provides a complete hardware inventory view of all BCM50 hardwa re
components to the FRU level.
Proactive Voice Quality Monitoring
With the proactive voice quality monitoring (PVQM) capability, you can set call-quality
thresholds for IP sets and receive an alert and if these thresholds are exceeded. You can
proactively identify voice quality of experience (QoE) issues for every call. In turn, you can
troubleshooting of voice-quality issues within the network.
PVQM supports calls from an IP set to any other set or trunk. The measured call-quality metrics
includes the following.
•packet loss
• inter-arrival jitter
System Overview
34 Chapter 2 System Overview
• listening R-value
• RTCP round trip delay
With PVQM, a system-wide summary view of threshold-violation alert occurrences is maintained.
Threshold violations can be sent as alarms and used by the central AppManager VoIP
performance-monitoring product from NetIQ to generate a system-wide view of the voice quality
of the network and to help diagnose voice-quality issues. The alarms include extensive call-quality
information in accordance with IETF RTCP-XR RFC 3611.
PVQM on BCM50
• provides the ability to monitor the quality and integrity of IP-based voice networking
• is a significant differentiator in VoIP convergence network sales with its market-leading,
proactive focus on every call.
• mitigates customer issues to determine whether the data network or the BCM is at fault
when call-quality issues situations occur
• provides consistency in the QoE solution across Nortel enterprise call servers to facilitate
mixed network deployments
Ad Hoc conferencing
Currently, the BCM supports three-party conferencing. Ad-Hoc Conferencing extends this
capability to support multi party conferencing.
Ad-Hoc conferencing
• provides a user interface model which is similar to the current F3 conference
• ensures no impact on the user’s feature button footprint (that is, no requirement exists for
additional IC keys or for an additional feature key)
• provides the current three-party conferencing capabilities, allowing users the flexibility to
have larger multi-party conferences
• supports up to 18 simultaneous participants on multiple conferences
Meridian Customer Defined Network Trunk Anti-Tromboning with integrated
applications
The BCM currently uses Meridian customer-defined network (MCDN) signaling to optimize
network–resource use to transfer or forward station-to-station calls. With this feature, voice mail
and autoattendant applications can use MCDN capabilities to optimize network use.
MCDN trunk anti-tromboning (TAT) on BCM50
• provides customers with optimal use of trunk facilities
• enables a large number of feasible networking scenarios to serve customers
With MCDN TAT, BCM can determine whether calls routed across a network by the integrated
AutoAttendant or Voicemail should invoke TAT or Trunk Route Optimization (TRO) MCDN to
optimize the trunking network connection.
NN40020-200
System Overview Chapter 2 35
Session Initiated Protocol
BCM supports H.323 and SIP VoIP basic call communication for BCM-to-BCM calls. H.323 also
supports the same features that the MCDN capability supports.
BCM50 3.0 introduces new SIP features including:
• “SIP REFER” on page 21
• “SIP proxy failover” on page 21
• “RFC 2833” on page 21
BCM50 existing SIP features include:
• support for the MCDN features with SIP
• expanded SIP interoperability to the CS1K and MCS5100
The MCDN supported features include:
• Private Name/Number
• Network Call Redirection Info (NCRI)
• Trunk Anti-Tromboning (TAT)
• ISDN Call Connection Limit (ICCL)
• Message Waiting Indication (MWI)
• Trunk Route Optimization (TRO)
In enterprise network systems, the SIP feature supports private numbering plans, optimizes the use
of network traffic (TAT/TRO/ICCL), and supports centralized voice mail applications (NCRI,
MWI) using the SIP messaging protocol. By making these capabilities available using the SIP
protocol, you can begin to transition your network to the latest standard.
Security
BCM50 3.0 security enhancements are an extension of the BCM50 platform. The new “Security
enhancements” on page 26 include the new features. The following section describes the main
security features with BCM50.
• “User account access management” on page 35
• “Secure interface and audit logging” on page 36
User account access management
This feature significantly improves BCM user-account access management by enhancing
password, session, account authentication, and access-management. These improvements align the
BCM with the security enhancements introduced with BCM50 and add incremental capabilities.
Password Management and Policy Enhancements include
• Minimize the vulnerability of passwords
— password characteristics are now more stringent (length, criteria)
— password aging, history and change notification added
System Overview
36 Chapter 2 System Overview
— forced password change on initial login
— password storage hashing with Secure Hashing Algorithm 1 (SHA1)
Session Management Enhancements minimizes the vulnerability of logged-on sessions for idle
session time outs.
Account Management includes
• Minimize the vulnerability of User IDs
— Automatic disabling of unused accounts
— Set-based administration requires user ID and password
Account User ID Access Privilege Management includes the logged-on user ID session and access
display.
These enhancements to user-account access management provide a secure BCM access
environment, which makes it difficult for a malicious user to gain access to a BCM. BCM owners
can enforce secure account-access controls to the BCM to ensure secure BCM management and to
increase protection against potential vulnerabilities.
Secure interface and audit logging
This feature enhances interface security by adding secure access controls, security audit logs
(configchange.systemlog), and system activity by User ID, date, and time. Secure Interface Access
and Communications Controls provide
• support for Secure Copy (SFTP) SSH encrypted file transfers
• support for Simple Network Management Protocol (SNMP) v2 and v3, including
encryption provided with v3
• BCM owner control of Nortel technical support access
• use of digital signatures and enhanced tamper detection to ensure trusted sources for
software upgrades (patches and software release upgrades)
• ability to test the system ability to generate alarms and logs, including system security
alarms and logs
Audit log tracks critical changes to the system and the logon attempts, including
• last successful login identification and interface
• last failed login attempt and total failed logons since last successful logon
• configuration change log to track configuration changes to system by User ID
• RADIUS Support (Centralized Authentication and Radius Client to authenticate and
authorize using a centralized RADIUS server)
In addition to supporting IPsec tunnels for management, the ability to encrypt SNMP and file
transfers provides BCM users an expanded capability set for secure interface communications.
With audit logging of long attempts, the BCM user can track security violation attempts and
determine further action. If you suspect a user ID security breach as a result of system
configuration changes, the audit logging of configuration changes provides traceability to user IDs
and interfaces.
NN40020-200
System Overview Chapter 2 37
An overall increase in security you have with effective logging capabilities for Audit Trail logs,
Alarm logs and Configuration Change logs.
If you require improved interface access and communications security for alarm, log, and file
transfers, you can use these security enhancements. As well, you can audit and identify the critical
system changes that specific users initiate.
Terminal and mobility support
The BCM50 Terminal and mobility support is equivalent to that of BCM 4.0. BCM50 supports the
following phones:
• IP Phone 1110
• IP Phone 1120e
• IP Phone 1140e
• IP Phone 1210/1220/1230
• T7406E Cordless Handset
• IP Audio Conference Phone 2033
• IP Key Expansion Module I24
• IP 11xx Key Expansion Module
• IP 12xx Key Expansion Module
• IP 12xx Key Expansion Module with Display
The IP phones incorporate network management and security enhancements. You can upgrade the
firmware with a patch or call sever release that provides the following:
• enhanced VLAN (configured manually or with DHCP) and PC VLAN (configured
manually) tagging
• enhanced display for local Network Diagnostic Utilities
For additional terminal and mobility supported devices, see the “BCM compatibility matrix” on
page 53.
Global markets
BCM50 voice prompts, which were introduced in BCM 4.0, include Polish, Finnish, Korean,
Turkish, and Czech.
The following additional capabilities are available:
• addition of second dial tone for PRI/BRI
— In some markets, a PBX must provide a local tone to the originating party (as opposed
to the central office).
— This feature adds the ability to provide the local tone.
• increased public received digit length from 7 to 12 digits
— Some markets require more than public received digits to support dial plans.
BCM50 regional bundles for APAC and EMEA are updated to include the GATI or BRI keycodes
to replace expansion chassis and BRI MBM where applicable.
System Overview
38 Chapter 2 System Overview
SRG50 Global Bundles are maintained and updated. SRG50 users geographic localization
enhancements of BCM50.
Localization is a key goal for BCM50. Onboard Analog and BRI trunk profiles are localized to
new markets to offer an integrated solution without dependency on external MBMs for small sites.
This solution offers easy installation, improved margins, and a competitive offer in global regions.

Windows Vista, Citrix Metaframe XP for Element Manager, and Citrix client support equivalent
to BCM 4.0. BCM applications for BCM50 support the following Vista versions: Microsoft Vista
Business, Microsoft Vista Ultimate and Microsoft Vista Enterprise. For more information about
BCM50 Microsoft Vista support, see “Microsoft Vista operating system” on page 27.
Field replaceable units
Field replaceable units (FRU) strategy is consistent with previous BCM50 systems, including a
replacement router and a BRI CDC card. CDCs are not hot-pluggable.
System Overview
40 Chapter 2 System Overview
Field upgrades
The BCM50 upgrade kit is available. Element Manager and NCM support remote and scheduled
upgrades from BCM50 1.0 and 2.0, not including router upgrade support.
Servicing
Serviceability enhancements in BCM50 include the following:
• BRI CDC offered as a FRU
• reduced dependency on DIP switches for Media Bay Modules as global profiles are
downloadable
BCM50 management
You can quickly and easily install, configure, and administer BCM50. These topics summarize the
BCM50 management areas:
• "Ease of installation"
• “Remote management accessibility” on page 41
• “On-box and device manageability features” on page 41
• “Set-based administration” on page 42, for no-PC programming of most of the system
• “Business Element Manager” on page 43, interface that supports all aspects of BCM50
element management
• “Network Configuration Manager” on page 45, for multi element support
Ease of installation
BCM50 installation easy with innovative hardware and management tools.
The simple rack-and-stack nature of BCM50 physical installation, with the multipurpose
RJ-45-based connector strategy, provides easy installation. The dedicated RJ-45 port for
management access provides easy access to the unit for on-site PC-based element management
tasks.
For BCM50 installations that require data networking, IP sets, or VoIP trunking, BCM50 can
function as a DHCP client to a network DHCP server for automated IP address assignment.
BCM50 can also function as a DHCP server to provide both IP phones and a directly connected
Element Manager PC with the IP configuration.
You can perform all configuration using the “Business Element Manager” on page 43.
Startup profile
To accelerate the initial installation programming of system-level parameters, you can use the
Startup Profile to quickly place the BCM50 in a basic operational state, ready to prog ram, withou t
having to use Element Manager or set-based administration.
NN40020-200
System Overview Chapter 2 41
The Startup Profile is an easy-to-use template you can datafill using Microsoft Excel.
The Startup Profile provides a quick interface to define, for example, the following parameters:
• system profile including country, telephony template, and key voice mail attributes
• system IP parameters
• system-level telephony attributes to automatically create the system DNs
• keycode information through automated application of keycodes
• users and groups
You fill out the template, save it to a USB storage device, and insert the memory stick into the
USB port of the BCM50 during the initial startup of the system. This information is read into the
BCM50 and applied during a single restart sequence.
The Startup Profile is similar to the Quickstart wizard of the BCM200 and BCM400, but it can be
datafilled and applied without an IP connection to the unit, a PC, or telephone. The Startup Profile
executes quickly, and includes a broad scope of system-level parameters.
Remote management accessibility
BCM50 has an integrated analog modem that can accept an incoming modem call on any BCM50
system line. You can configure the BCM50 system to have the modem automatically answer a
specific line with configuration options. You can manage from BRI. Remote users can also initiate
a voice call to a person or an autoattendant, who transfers the call to the modem.
The analog modem also supports callback for management access to the BCM50, which can be
used to support automatic dial-out on SNMP traps and automated sending of Call Detail Records
(CDR) to a remote CDR collection point. The modem is also enhanced with CLID.
Although Nortel does not recommend that you use the analog modem to transfer large files, the
modem provides a flexible method of remote access to remotely perform all programming tasks.
The BCM50e and BCM50a provides remote management capability with a high-speed
connection. Tasks such as transferring backup files to a remote destination and transferring
software update files, CDR records, and log files can occur more efficiently than over the analog
modem.
On-box and device manageability features
BCM50 has an SNMPv3 interface that includes support for SNMP v1 and v2 for management by
legacy SNMP managers. SNMPv3 delivers improved security features for SNMP device acces s.
The BCM50 main unit supports the following versions of SNMP:
• SNMP v1—the first implementation of SNMP; this version supports protocols such as IP
• SNMP v2C—provides improved efficiency and error handling
• SNMP v3—provides improvements in security and privacy
Using the BCM50 Element Manager, you can select which versions of SNMP you want the
BCM50 agent to support.
System Overview
42 Chapter 2 System Overview
Management Information Bases (MIB) provide access to the managed objects of a system and
specify the format of traps. BCM50 supports these standard MIBs for remote management:
• MIBII RFC 1213—second version of the MIB for use with network management
protocols in a TCP/IP-based internet. This MIB includes System Group and Interfaces
Group and is a baseline RFC implemented by data-networking systems.
• Entity MIB RFC 2737—describes managed objects used to manage multiple logical and
physical entities to manage by a single SNMP agent.
• System Host MIB RFC 2790 MIB for to manage host systems — defines a set of objects
common across many computer system architectures that are useful to manage host
computers, such as memory and CPU.
• SmallSiteEvent MIB for traps.
• RFC 2261—SNMP Framework MIB.
BCM50 adopts the Common Information Model (CIM) standard according to the industry
standards organization Distributed Management Task Force (DMTF), which provides a modeled
method to manage system-programming parameters. BCM50 uses the transport mechanism CIM
operations over HTTP using XML, also referred to as CIM-XML. The BCM50 CIM-XML
interface provides a consistent way to manage data on the device, whether by the BCM50 Element
Manager, NCM, or third-party network or service-management applications.
Log management
BCM50 log management includes, in addition to the component logs that BCM200 and BCM400
systems provide, security logs, configuration change logs, alarm logs, and system logs.
Set-based administration
BCM50 gives you the ability to use a telephone interface to program much of the BCM50 system.
Set-based administration benefits include:
• BCM50 installations that have no TCP/IP connectivity
• BCM50 installations where the installer has no on-site access to a computer
• installers who prefer the speed of programming using set-based administration
• installers who are familiar with the Norstar interface
With set-based administration, you can manage
• core telephony
• voice mail services
• IP network settings
• keycode entry
• admin password change
• modem on or off
Support is available for multiple languages, consistent with Norstar set-based administration.
NN40020-200
System Overview Chapter 2 43
Business Element Manager
Business Element Manager provides access to BCM50 information in a new off-box management
architecture. Element Manager has a task-based interface for ease of use, see Figure 9.
If you use Business Communications Manager Unified Manager, performing common BCM50
programming tasks is easy, fast, and information-rich with Element Manager, which requires
minimal clicking through the interface to perform tasks. You can access any programming screen
in three or fewer mouse-clicks.
Programming data is enhanced in the Element Manager to quickly show all the associations
between data in the form of tables. This eliminates looking in multiple places to obtain a system
view of the programming.
Figure 9 Business Element Manager interface
Element Manager runs on a PC, and the information required to draw the screens is contained
locally within the client application. The only data transferred between Element Manager and the
BCM50 are queries and actual data. Element Manager has familiar Microsoft Office-like
capabilities, such as the ability to sort information.
Element Manager integrates all the traditional BCM administration tools, including managing
backups and software updates.
Element Manager has an element navigation panel to organize a network of elements. You can
simultaneously manage multiple elements. After you connect to an element, you can perform
configuration and administration tasks.
Business Element Manager administration interface
The Element Manager administration management environment includes
• BCM50 diagnostic and maintenance tools, including access to BCM Monitor.
• Fault management for viewing BCM50 alarms. You can set which alarms are displayed in
the Element Manager alarm browser and which alarms trigger an SNMP trap.
System Overview
44 Chapter 2 System Overview
• Log management for off-box transfer of logs, including component logs and administrator
logs such as alarm log, security log, configuration change log, and system log.
• Software management tools for software updates (for example, for corrective software)
and software upgrades.
• Backup and restore. You can schedule full back ups with the option of excluding certain
components which are presented in the user interface. A scheduled backup provides the
ability to routinely perform a backup, which you can save on the BCM50 hard drive or
transfer to an off-box destination such as network folder, FTP server, or locally attached
USB storage device.
For backup and restore, software management, and log management, a flexible set of source and
destinations is supported along with protocols to access them. For example, you can save backups
from the BCM50 to either the USB port, the Element Manager client PC (on-demand only), a
shared drive available on the network, or a remote FTP server.
Software updates
To ensure that BCM50 maintenance costs are low, even in an environment of security and
corrective content updates, the BCM50 handles software updates as follows:
• You can download software updates to the BCM50, either on-demand or according to a
schedule, from a USB port, a shared network drive, a remote FTP server, or a client PC.
• Update software is automatically checked against the BCM50 software history and
validated before you transfer it
• You can schedule the software update separately. For example, you can schedule a
download for Tuesday night, but you can schedule the application for Friday at 2:00.
• You can program multiple software-update packages to be applied at the same time.
• One software-update package can include updates for multiple software components.
While many software updates do not require a system restart, some software components
require a restart for the update to take effect. No more than one s ystem restart is required if
one or more of the software components being updated by the software-update package
requires a reboot.
• Software upgrades are handled in the same way and use the same tool as software updates.
• You can set up the entire software-update process for hands-off operation if the software
content can either be downloaded remotely or sent and installed from the USB port.
Keycodes
The BCM keycode structure now includes the following capabilities:
• One keycode validates all feature entitlements, which simplifies installation.
• You can apply keycodes in a number of ways:
NN40020-200
— through Element Manager
— through set-based administration
— through NCM
— through a USB memory stick
• Enable BRI with a keycode
Network Configuration Manager
Many Business Communications Manager customers already use the optional client/server-based
management application Network Configuration Manager (NCM) to manage their multisite
BCM200/400 network. Designed to provide a system-wide perspective for up to 2000 BCM
devices, NCM is a centralized database that stores information about every Business
Communications Manager device on your network.
NCM for BCM50 includes centralized backup and restore management, common file distribution
(for example, system greeting files), parameter configuration, and automated software-update
distribution. You can manage large BCM50 networks and mixed BCM50/200/400 networks using
the NCM.
BCM50 applications
System Overview Chapter 2 45
BCM50 has a wide range of applications. You enable these applications through keycodes, and
you require no additional hardware.
BCM50 provides 10 ports to connect to CallPilot and Intelligent Contact Center. Each port
supports one connection to an application. For example, four callers can leave voice messages, and
two callers can be in the autoattendant, while four callers listen to voice messages. The number of
ports can support a fully configured a BCM50 system with a full complement of voice mailboxes.
BCM50 is delivered with Mailbox Manager and CallPilot. Keycoded CallPilot options are also
available, as are other BCM50 applications, such as Meet-Me Conferencing, LAN CTE, Personal

Intelligent Contact Center
Intelligent Contact Center (ICC) is an evolution of the existing Call Center capability on BCM.
ICC has the same functionality as the current Professional Call Center with the ability to choose
exactly the number of agents and skillsets that a customer or customer site requires. BCM50 3.0
introduces two new features, “Intelligent Contact Center API's” on page 24 and “Silent
Record-a-call” on page 23.
The existing Intelligent Contact Center provides the following features:
• Provides maximum flexibility in granularity.
• Any combination of Agents and Skillsets within the boundaries of a platform. This
combination confusing of features between Basic and Professional. Channel partners and
customers need not to worry about which functionality belongs to which product.
— Contact Center with Professional Contact Center level of functionality.
• Simplifies product offering
— Contact Center, x skillsets, x agents, RCC
— Eliminates Basic, Pro, and upgrade between the two
• Increases market potential
— Customers that require more skillsets than agents
Example: Real Estate — 3 receptionists (3 agents) answering telephones for 20 real estate
agents (20 skillsets)
— Big-box retail — 3 receptionists (3 agents) answering telephones for 12 departments
(12 skillsets).
Optional components include
• x agents (keycodes offer granular selection of the number of desired agents)
• x skillsets (keycodes offer granular selection of the number of desired skillsets)
• Reporting for CC
• Multimedia CC
For more information, see the Intelligent Contact Center Set Up and Operation Guide.
Multimedia Contact Center
Agents and callers can use the Multimedia Contact Center to participate in multimedia calls that
include
• speaking over a Public Switched Telephone Network (PSTN) voice connection
• text chatting
• exchanging and viewing Web pages
• viewing screen captures (sent by an agent to the caller)
System Overview
52 Chapter 2 System Overview
Multimedia Contact Center supports two call types:
• Phone-and-browser calls (using PSTN), which integrate a standard voice call with a
Contact Center agent and a Multimedia Contact Center browser call session with
follow-me browsing, text chat, and screen-capture push.
• Browser-only calls, which have the same browser features of phone-and-browser calls but
no voice call component.
Local Area Network Computer Telephony Engine
BCM Computer Telephony Integration (CTI) products provide an interface between your personal
computer and your BCM50 system. With these products, you can use telephony applications
through the Windows operating system to control your telephone.
One BCM CIT software component is Local Area Network Computer Telephony Engine (LAN
CTE). LAN CTE provides an interface between your personal computer, your telephone, and the
BCM50 system. With LAN CTE installed on your computer, you can run LAN CTE or TAPI
applications to communicate with and control your telephone.
For more information, see the LAN CTE Configuration Guide.
Call Detail Recording
Call Detail Recording (CDR) is an application that collects call activity. Each time a telephone call
is made to or from your company, CDR can record information about the call. You can use the
information CDR collects to create reports about call activity. CDR also provides an interface to
third-party applications for call accounting and billing.
For more information, see the Call Detail Recording System Administration Guide.
Personal call manager
Personal Call Manager is a TAPI-based application that provides an easy-to-use interface between
your computer and your telephone. You use the telephone to speak with a caller. You can
customize your Address Book and your calls. Basic functions that Personal Call Manager
performs include making and answering calls, placing calls on hold, transferring calls, and making
conference calls.
For more information, see the Personal Call Manager User Guide.

BCM50 hybrid configuration
A BCM50 system is defined as a hybrid configuration if it is configured with a mix of IP phones,
IP clients, or IP trunks and with non-IP phones, terminals, or trunks (digital phones, analog
phones, FAX machines, digital T1/E1/PRI trunks, BRI interfaces, and analog trunks).
For a BCM50 system deployed in a hybrid configuration, it is recommended that the total number
of stations (digital phones, IP phones, analog terminals, BRI B channels for station side) not
exceed 50. Additional stations can reduce the performance effectiveness of the BCM50.
System Overview
58 Chapter 2 System Overview
If you use Meet Me Conferencing, Nortel recommends you increase the number of voice mail plus
Call Centre (Voice Mail + CC) resources from 10 to 15.
When the number of voice mail plus Call Centre resources exceeds 10, the following engineering
rule applies:
• For a BCM50 system deployed in a hybrid configuration, if the number of voice mail plus Call
Centre resources required exceeds 10 (maximum 15) and the trunks use the G.729 codec, the
number of IP trunks must not exceed 10.
• The number of IP trunks may number 12 if the trunks are configured with the G.711 codec.
