The Business Communications Manager Nortel Networks delivers global, industry-leading enterprise solutions for businesses of all types and sizes. These solutions include communications systems, call center and multimedia messaging applications, in addition to data access products. Our customer-driven solutions increasingly take advantage of Internet and computer integration, helping drive business performance and creating a greater competitive advantage for our customers.
One of the Nortel Networks enterprise communications solutions is the BCM. Originally introduced to the market in early 2000, Nortel Networks BCM solution is one of the most sophisticated and reliable converged voice and data solutions available for branch offices and small to medium-sized businesses.
The BCM is a converged communications system that delivers Nortel Networks reliable and proven voice processing, feature-rich business telephony applications and data networking services over a single platform that is managed via a browserbased tool. As a highly reliable, scalable and integrated voice and data solution, BCM is designed to align with the universal core objectives of the single-site, medium-sized and multisite enterprise to increase revenues, improve customer service, streamline costs and expand market reach. 4 Business Communications Manager 3.0 Business Communications Manager 3.0 builds upon the capabilities delivered in previous releases to raise the bar as the standard for IP telephony solutions for the enterprise small site.
Release 3.0 dramatically increases the value of the BCM as a branch office solution in small or large corporate networks with the addition of interactive voice response (IVR) support, which can drive cost reductions and revenues and multisite management to lower the overall cost of ownership. The increased TDM station capacity, when considered alone or in conjunction with the IP station capacity, allows the needs of sites with between 16-200 users per system to be met while preserving the choice of a TDM, IP or hybrid telephony strategy.
Additionally, Release 3.0 incorporates a number of “Design for Serviceability” aspects that makes the BCM easier to install, support and service. BCM 3.0 release introduces significant improvements to the platforms functionality, including:
• Interactive Voice Response (IVR) is a self-service application designed to allow businesses to be accessible to their customers 24 hours a day, 365 days a year. Businesses can supply callers with access to a broad range of information simply by responding to a series of prompts via their touchtone phones. BCM 3.0 provides an integrated IVR runtime engine (RTE) that sits on top of Voice Applications Layer similar to Voice Mail or Call Center and interprets the IVR applications. IVR applications developed using Portal Solutions PeriProducer, or PeriPro Application Builder environment and PeriStudio Audio Development Tool, can be installed on the BCM in the field and can run on the BCM-IVR.
• Network Configuration Manager (NCM) 2.0 is a multisite management feature that provides centralized configuration and system management capabilities for a number of BCMs in a network. NCM delivers a management capability for multisite BCM customers and channel partners, enabling them to significantly reduce the total cost of ownership of their BCM systems.
• Increased TDM station capacity means that the number of digital station sets has been increased. The number of station sets supported on the BCM is a critical capability for meeting the needs of larger sites. Through a more efficient use of existing resources, the number of digital sets supported has been increased to a theoretical maximum of 192. In practical solutions with a mixture of trunks and stations, BCM 3.0 supports from 128 to 160 digital sets, effectively doubling the previous digital station capacity.
• Hardware platform improvements offer ease of installation, service and use. BCM 3.0 introduces a number of key improvements to the hardware platform. First, the number of Media Bay Modules supported on the base system has been increased to four, allowing more 5 sophisticated solutions at a lower cost to the end user. Second, the number of versions of the base platform has been reduced to two, a standard platform and a redundancy version, reducing stock requirements and order complexity. Third, the platform now incorporates “Design for Serviceability” features that make the BCM easier to install, set up and service. In addition, the capability for field installation of a WAN card has been introduced and the Media Services Card is field replaceable. Finally, BCM 3.0 offers a new, lower-cost hardware platform. This platform has two bays for Media Bay Modules and meets the needs of smaller, more price-sensitive sites.
• BCM 3.0 Upgrade is the upgrade mechanism for BCM; it has been redesigned for BCM 3.0 to reduce the time it takes to upgrade previous releases. The upgrade supports field upgrade from either BCM 2.5 or 2.5 FP1 releases to Release 3.0.
• Other features add value to Release 3.0. Telephony routing enhancements allow routing on 12 digits dialed and multiple level (=2) automatic route selection. Call Detail Recording (CDR) has been enhanced to allow pull transfer of CDR data. Silent Monitor for Call Center, serving more advanced call center needs and Silent Monitor of Hunt Groups for less formal call centers, provide ability for a supervisor to silently monitor calls. An administrative edition of Desktop Assistant Pro is a downloadable client that allows a system administrator to configure any set on the system remotely. A client diagnostic tool for the i2050 Software Phone provides diagnostic information. Improvements to Unified Manager include a redesigned login page, a new network update wizard with network-loaded templates and button programming for the Add User wizard.
The Business Case for Business Communications Manager A Convergence System Convergence is best discussed by looking at three distinct dimensions of the IT environment:
• Applications 6 At the Infrastructure Level Since IT managers are increasingly measured on time-to-market for new applications, in addition to more traditional metrics tied to budget and trouble resolution times, it is critical for businesses to have a multiservice corporate networking infrastructure that is application ready.
With the growing diversity of applications, in terms of both their performance needs and business criticality, the networking infrastructure needs to deliver rock-solid reliability. Convergence is the means to the end. In this case, convergence means achieving the highest levels of price/performance and the highest levels of affordable network reliability. This end should be addressed holistically, at the switch and network level, with proactive network management supporting it. At the Management Level People costs make up a significant portion of a business IT budget as much as 40 percent in many cases.
Converged voice/data IT organizations can better manage the transition to unified applications and infrastructures, which can go a long way towards justifying cross-training of telephony and data resources, with their strengths in understanding the end user and network, respectively. Operational procedures have to reflect the growing business criticality of certain applications. Comprehensive management systems with uniform graphical user interfaces (GUIs) incorporating network, policy and service management not only improve overall network performance but also permit better use of scarce human resources.
At the Applications Level The growing popularity of the Internet and the standardization of Internet Protocol (IP) are inspiring companies to combine all communications, allowing them to simplify voice and data architecture and ultimately save money. At the application level, it is widely accepted that new applications, whatever their form, will be developed on IP and that existing applications should be migrated to IP as best suits a business specific needs.
These applications need to be blended seamlessly with unified messaging supporting voice, email and fax communications; however, the real-time nature of these applications introduces some new infrastructure demands for time-critical performance and reliability. 7 IP telephony means lower costs through network simplification, higher employee productivity, better customer service, more revenue and greater profitability. Nortel Networks BCM and its proven Voice over Internet Protocol (VoIP) technology can boost business performance and accelerate business success today. The bottom line: BCM merges voice and data services in a unified system that meets business demands at the infrastructure, management and the application level delivering business-critical availability, application-optimized performance and lower life-cycle costs, including operations, capital per bit of capacity and bandwidth costs.
An Internet Telephony Solution To forward-thinking CEOs, convergence suggests new ways to accomplish these established goals:
• Set new standards in customer loyalty and satisfaction
• Rapidly deliver new products to existing and emerging markets
• Retain and attract skilled resources
• Enhance employee satisfaction and productivity
• Make efficient use of IT resources. To attain these goals, CEOs have emphasized investments in supplier and customer integration. Such investments lead to integrated business systems, which constitute the kernel of an ebusiness model. While CEOs may define business needs, satisfying these needs falls to another category of executive: the chief information officer (CIO). And, in fulfilling their assigned role, CIOs rely on information technology.
This progression has been pronounced in certain industries, such as finance. Now, however, companies of all types are building their businesses around their networks and networked application environments. CIOs recognize that the emerging ebusiness environment is driving the need for quicker time-to-market for new applications, improved price/performance, increased reliability and scalability and management simplification. With the BCM IP telephony offerings, customers can experience the benefits of IP while retaining the applications, reliability, features and functionality they have come to expect from their traditional voice networks.
IP telephony is now a key factor in differentiating business 8 operations and customer service strategies, offering companies a key competitive edge in a global economy where the nearest competitor is now only a click away. BCM delivers a business-building suite of advanced applications to enable the delivery of new services and dramatically increase revenue opportunities. For businesses and organizations of all sizes, this includes multimedia contact centers and such high-powered business productivity tools as unified messaging and management, computer telephony integration (CTI) and mobility.
Customers can also save time and money through simplification because the BCM approach to IP telephony literally transforms multiple networks into a single, multiservice network, while driving simplicity to the desktop. Importantly, it protects a customers investment in their current network. No forklift is required! The result is a powerful network that is reliable, rich in features and low in latency that offers economical and efficient solutions.
Target Markets Nortel Networks has identified the following three primary customer profiles as key target markets:
• Large Enterprises with branch locations
• Medium-sized, multisite businesses
• Standalone, single-site customers (up to 200 people). Large Enterprises with Branch Locations Companies deploying a number of similar configurations in their small-site networks improve network efficiencies with the BCM.
These businesses can use the BCM to:
• Standardize all their companys communications needs with a single product
• Network multiple locations that use their existing wide area network technology
• Simplify their business processes by using a single vendor
• Manage their telephony and data computing with remote management software tools.
Examples of large enterprises with branch locations include:
• Financial institutions
• Insurance agencies 9
• Retail chains
• Discount stores. Medium-sized, Multisite Businesses The BCM provides the integrated voice and data solutions that larger retail outlets, such as grocery, general retailing and home improvements, may be considering.
Furthermore, with its high level of reliability and ease of use, the BCM accomplishes this integration while protecting the customers investment for the future. Standalone, Single-site Customers Companies seeking the competitive advantage of advanced customer service, and ecommerce options, appreciate the robust and future-proof performance BCM offers with its sophisticated voice telephony and Internet access. Any company with 16 to 200 users in a single location can use this product to optimize their telecommunications and data computing activities.
Examples of medium-sized and small business customers include:
• Law offices
• Real estate firms
• Travel agencies
• Small manufacturing companies. Vertical Markets BCM offers a best-in-class, complete, converged voice/data solution to enterprise small sites across all industries.
There are, however, key features and applications that make BCM an attractive solution for the following specific industries:
• Education The built-in capability of BCM is very appealing to the K-12 market with the drive to “wire” classrooms for Internet access. And, as they wire for Ethernet, they can use 10 the IP station support of BCM to provide voice connectivity to the classroom as well. The importance of a telephone set in every classroom has increased dramatically.
• Retail In addition to IP telephony, the powerful call center capabilities available with BCM, including the Multimedia Call Center and ipView Softboard, can help retail customers deliver the top-flight customer service that leads to success. The IVR capability, available with Release 3.0, enables users in environments, such as pharmacies, to implement applications that help to offload repetitive tasks.
• Government In this market, BCM reduces costs by creating a converged data/telephony network architecture.
Advanced telephony features such as Call Transfer between branches, conference calling, call centers and wireless telephones streamline internal operations and increase efficiency.
• Finance BCM provides financial institutions with the capabilities to evolve their branch telephony communications to IP telephony, while offering the benefits of lower wide area costs, operational simplification of moves and changes and security.
• Professional services Businesses in this market, particularly those with branch offices, can realize cost savings by using an IP network to support telephony between sites. Further, in an environment where a Meridian* 1 PBX is already installed at the central site, centralized voicemail and four-digit dialing can be extended to all branch locations across the wide area network (WAN).
• Restaurants VoIP and call center solutions offered by BCM allow businesses in this market to save on communications costs.
Linking phone systems and the Internet means that a call to any restaurant in the chain moves as IP packets over a data network to the call center at the main location. Restaurants can achieve more uniform and consistent levels of customer service across all their branches.
Business Communications Manager Key Benefits As businesses look to balance their business goals and objectives with the evolution of telecommunications and computing, they are finding that convergence products must meet the following key requirements:
• Streamlined costs 11
• Increased revenues, expanded customer base and improved customer service
• Simplified administration
• Future-proofed networks.
Reliability Customers are searching for a voice/data solution that provides the ultimate in reliability. The heartbeat of any business is its ability to send and receive information (through phone calls, data, images) to and from customers and suppliers. Dial tone is not an option and companies need to be able to rely on their network to transmit the required information as quickly and reliably as possible. Our customers are not in the business of managing technology. They require highly reliable solutions that allow them to focus on their core business. The BCM Media Services Card (MSC) provides reliable call processing and media processing of voice channels and contains media services processor expansion cards that provide digital signal processing (DSP) resource control for applications. MSC call processing operates independently of the BCM platforms Microsoft NT Embedded v. 4.0 operating system (OS). If the OS malfunctions, call processing remains unaffected.
Availability With the expanding use of the Internet to connect businesses together with their customers and other businesses, office hours are increasing to 24 hours a day, 7 days a week, 365 days a year for more and more companies. Converged systems not only have to operate reliably they have to be available reliably to match these hours. Business applications and voice/data solutions allow unattended systems to carry on a companys business when all staff members at that location have gone home for the day. Built in with the design of the BCM are features that increase availability. The DSP resources of the Media Services Card mentioned above, along with the systems central processing unit (CPU),provide redundant processing capability.
A number of strategies can be used with the BCM to increase system availability even further. The Redundancy Feature option provides dual, hot swappable power supplies along with dual chassis cooling fans and data protection with RAID hard disk drive mirroring. External uninterruptible power supplies connected to the BCM can be used to handle power interruptions. And, the hardware platforms unique Design for Serviceability features minimize downtime for servicing of the BCM. 12 Streamlined Costs The ultimate goal of any business is to optimize shareholder value. An obvious and necessary first step towards reaching that goal is streamlining costs while boosting productivity. Our customers are looking for solutions that allow them to reduce their overall cost of ownership (upfront equipment costs, network service costs and maintenance and management costs) and increase employee productivity. The BCM integrates voice and data components (CPE and DTE) into a single platform that can reduce costs by replacing individual components such as voicemail systems, automated attendant capabilities, computer telephony and remote access servers, multiplexer or CSU/DSU, router, modem and DHCP server.
This next-generation platform integrates PBX/KSU, IP router, VoIP Gateway and IP services as well as voice applications and management software and servers, to provide a complete, unified, value-added solution. These powerful services and business applications multiply the productivity of employees and help to manage human resources costs for the company. Increased Revenues: Expanded Customer Base and Improved Customer Service The second step in maximizing shareholder value is increasing revenue. Businesses are looking for solutions that will allow them to take advantage of market opportunities, compete more effectively and drive revenues. Expanding market reach and increasing the number of customers works directly toward increasing revenues. In todays highly competitive and rapidly changing marketplace, most businesses understand that customers have choices and demand superior customer service. Businesses are seeking solutions that enable them to deliver outstanding customer service. The BCM has more than 150 powerful software applications preinstalled.
Some applications work immediately after the system is installed, while others can be enabled and downloaded locally or remotely for implementation as business requirements evolve. 13
These applications include:
• Multimedia Call Center permits businesses to tap into the power of the Internet to expand into and reach new customers and to increase company awareness and revenue.
• Voice Messaging offers a choice of Norstar* or CallPilot* Voice Mail interface that allows for at least 200 hours of message storage and up to 1000 voice mailboxes. Voice Messaging is available as a try-and-buy option, which can be activated for 60 days.
• Message networking links CallPilot with other voicemail systems and allows the exchange of voice messages between users at different sites on a network connected by TCP/IP or MCDN networking.
• Unified Messaging allows users to manage voice, fax and email messages directly from their multimedia-equipped PC or laptop.
• Call Center, Professional Call Center and Call Center Reporting offer dynamic call handling and reporting applications that have been steadily enhanced with each new release. For instance, the number of queues, or skillsets, has been increased to 50 in Professional Call Center and improvements in agent display information have been made to include dialed number identification service (DNIS), allowing the person in the queue to see the number of an incoming call.
• Custom Call Routing (CCR) ensures that callers reach the right department or person on the first try.
• Attendant Console allows telephone attendants to monitor phone calls from their computer screen and answer and route them with a simple point and click of a mouse. Attendant Console runs on industry-standard Windows® 95/98/2000/NT or XP PCs and operates in a multitasking environment that lets attendants use their PCs for other work when not actively handling calls. Attendant Console is available as a try-and-buy option (one seat), which can be activated for 60 days.
• Fax Messaging allows the user to receive, send and forward faxes in the same fashion as voice messages.
Fax Overflow prevents customers from missing faxes by sending overflow faxes to a Fax Overflow mailbox, which stores the faxes until the fax machine is able to print them. Fax on Demand allows a user to retrieve documents stored in special mailboxes. Fax Suite provides Fax Messaging, Fax Overflow and Fax On Demand as a bundle. Fax Suite is available as a try-and-buy option that can be activated for 60 days. 14
• LAN CTE allows customers to use the system as a TAPI Server. This capability means that any TAPI-compliant application running on a Client PC can control telephones on the BCM system via TAPI. LAN CTE Server is available as a try-and-buy option that can be activated for 60 days.
• Personal Call Manager (PCM) is the award-winning telephony application available on BCM. It is designed for users on the Windows 95/98/2000/NT/XP operating system and brings much of the feature-rich telephony user interface to the desktop computer.
• eMobility provides wireless functionality without losing the benefits of the wireline system. Users can publish one telephone number and receive all calls on both their desk set and their portable. The roaming feature allows a portable user to make and receive calls and access business features anywhere within a coverage area.
• Unified Manager is a software tool that comes standard on every system and is used to manage the BCM at a single site. Unified Manager is a Java-enabled Web browser that provides a series of windows and menus that allow the user to navigate through the different areas of the application and program the system.
Tailored to the business processes of the company using the BCM, these applications can work to increase revenues through allowing receipt of information that might not otherwise get through. For example, in a restaurant using the BCM, a well-executed messaging application can ensure reservations are received and confirmed while staff members are busy with other duties. Simplified Administration There is a fundamental fear faced by some considering IP telephony that convergence will exponentially increase the complexity of their network and that the resulting administration will be unmanageable. With Unified Manager, a Web-based management tool, the BCM can be configured and managed from any PC on the network.
Administration is further eased by the strategic use of Meridian Customer Defined Networking (MCDN) and Q.SIG (Europe) voice networking to support networking between BCM nodes and a Meridian 1 hub system, for centralized PSTN trunking, a coordinated dialing plan and name and number ID delivery between network locations. Also, the use of IP telephones greatly reduces the effort and cost previously associated with user moves, adds and changes. BCM is compatible with Meridian 1 Internet Telephony Gateway and can share the Meridian Mail or CallPilot* Voice Mail of a Meridian 1. A consistent interface is provided for all voicemail users and the system uses the Unified Messaging client from CallPilot, which has been 15 enhanced to support other popular third-party email packages. This adds additional strength to the overall simplification of an extremely powerful product. Multiple BCM systems within a network can be efficiently managed using the BCM Network Configuration Manager (NCM) tool. This powerful server/client software running at a central operations center allows programming changes to be distributed to all BCM systems or to groups of BCM systems within the network. Programming changes can be scheduled for distribution at off-peak hours.
Changes made to the BCM systems within a network include auto attendant and call center greetings, auto attendant schedules, custom call routes, IVR scripts and keycodes. Future-Proofed Networks Potential customers are concerned about investment protection and their ability to strategically place themselves in a solid, viable position for the technologies of tomorrow. The BCM has evolved to support IP telephones and to integrate with leading-edge networking technologies such as virtual private networks (VPN). BCM is aligned with Nortel Networks Succession Strategy, guaranteeing a smooth migration path to pure IP solutions. When this migration strategy and vision towards IP is combined with the BCM architecture and its ability to support numerous PSTN connections points (BRI, PRI, T-1, E-1 or analog), it is not difficult to demonstrate that this product is intended for investment protection and long-term product and service viability. Data Capabilities BCM provides a combination of routing services. IP routing is provided via static routing, RIP, RIP2 and open shortest path first (OSPF). BCM supports both basic and stateful packet filtering to provide security when passing packets. Five proxy firewall systems (HTTP, SOCKS, IPXWINSOCK, NAT, PAT and DNS) are supported.
BCM also provides a number of services that enhance IP routing and IPX support via the local area network (LAN) segment. Network Address Translation(NAT) (NAT) allows address allocation that provides for routing stability and network scalability. DHCP provides automatic assignment of IP addresses and BCM has a built-in DHCP Relay Agent to allow pass-through of DHCP traffic to and from LAN connected devices. DNS maps easy-to-remember names to IP addresses and Web caching allows multiple users to share information downloaded from the Internet. 16 Platform Services The BCM system can be accessed remotely via a WAN/Internet connection or a dialup connection.
The dialup connection is established via a built-in V.90 modem, which creates an IP connection that allows the IP-based management tools to function. BCM also provides a tool called BRU that allows administrators to back up and restore all customer configuration and user data. 17 BCM Handbook Introduction Telephony Data Capabilities Messaging Voice over IP (VoIP) Voice Networking Call Center Interactive Voice Response (IVR) Mobility Computer Telephony Integration (CTI) Virtual Private Networks (VPN) System Management and Software Options BCM 3.5 Updates Appendix and Glossary Index Hardware 18 Hardware Chapter Highlights.

Figure 2-1 BCM400 BCM200 The chassis comes fully equipped with a Pentium® III 700-megahertz (BCM400) or a Pentium Celeron™ 850-megahertz (BCM200) processor, 256Mb of RAM, a 20 GB hard drive and a 350- watt power supply, all housed in a 19-inch, rack-mountable chassis. The chassis also comes equipped with integrated features like voice, data and management applications working in concert with Microsoft Windows NT Embedded operating system.
20 The main component of the BCM is the base unit. The base unit contains the following powerful parts:
• Intel® Pentium® III 700 MHz (BCM400) or a Pentium Celeron 850MHz (BCM200), CPU
• 256 MB SDRAM
• 20 GB hard drive
• 2 10/100 BaseT Ethernet ports (on-board)
• 1 V.90 embedded modem (North America units only)
• 2 PCI slots (one used by the Media Services Card and one for adding a WAN interface card)
• 4 media bays in BCM400, 2 media bays in BCM200
• 350 watt power supply (PS)
• Windows NTE 4.0. The BCM base unit controls all tasks, including call processing, voice messaging and data routing. The base unit also contains telephony hardware and data networking hardware components. Making and receiving calls is crucial to any business.
The call processing capability of BCM has been designed to process calls even when the Windows NTE operating system is out of service. The BCM has been designed for flexibility and scalability, with support for pluggable and interchangeable Media Bay Modules. Release 3.0 now offers the BCM400 platform with four bays for Media Bay Modules. This addition will simplify configurations and eliminate the need for the Expansion Cabinet. It also reduces the total cost of ownership for this configuration. When coupled with an Expansion Cabinet, the system can grow to support a maximum of 192 digital stations or up to 90 IP telephones; however, this is configuration dependent. 240 stations is the maximum capacity, with a mix of IP and digital stations, when 100% IP trunking is used.
The BCM400 is available in a standard model or a redundant feature option model, which includes dual, hot-swappable power supply, dual chassis cooling fan and RAID mirrored hard disk drive redundancy. 21 Figure 2-2 BCM 3.0 is also available on the BCM200 platform, which provides two bays for Media Bay Modules. The BCM200 has a lower removable tray, similar to that in the BCM400, for improved serviceability of the platform in a lower-cost version. The BCM200 cannot be expanded using an Expansion Cabinet and is designed to meet the needs of customers with 32 or fewer users per system. The BCM200 comes in the standard version and may be upgraded in the field with an RAID upgrade kit.
