Small and Medium Business Solutions Overview and Configuration Guide
This document provides the steps to configure three reference topologies
and their interconnections for the Small and Medium Business (SMB)
portfolio.
Use these example topologies only as a reference when you configure
your unique solution.
To reduce redundant documentation, reference the specific quick install
guides, configuration guides, and release notes.
Configuring each of the SMB reference topologies consists of individual
device configuration and solution-level configuration. All devices
(Business Secure Router [BSR222], Business Ethernet Switches [BES50,
BES100/200, BES1000], and Business Access Point [BAP120]) include a
Web interface to configure the device. The Element Manager provides a
centralized management application for launching these Web interfaces.
The Element Manager also provides integrated configuration panels for the
Business Communications Manager (BCM) and for the Business Ethernet
Switch (BES) devices.
9
The Business Element Manager (EM) provides a computer-based client
interface that can connect to devices over an IP network and display the
programming interface for that device. You can manage SMB devices using
the Web-based user interface that you launch from the Element Manager.
Through the Element Manager, you can configure necessary device
parameters and all the parameters for each of the reference topologies.
How to use this guide
Use this document to guide you through the steps that are required to
configure your site.
Small and Medium Business Solutions Overview and Configuration Guide
Assemble all tools and documentation required to configure your SMB
network. See "SMB Preconfiguration checklist" (page 12).
Determine which reference topologies and interconnected topologies most
closely resemble your unique solution.
Then read the following sections of this guide for more detail:
•
"New products" (page 13)
•"Existing products" (page 15)
•
"Reference topologies and assumptions" (page 18)
The reference topologies do not represent a definitive solution for your
network but do offer detailed procedures that can provide a guideline for
your implementation.
•
"IP addressing for SMB devices and DHCP" (page 19)
•
"Installing the Business Element Manager" (page 21)
Stand-alone SMB sites
If your requirement is
•solely for data connectivity with no requirement for voice solutions, then
configure your site based on the "Smaller converged site (Greenfield
and infrastructure replacement)—reference topology 2" (page 37).
•
IP or traditional telephony or both, and data connectivity, then configure
your site based on the "Smaller converged site (Greenfield and
IP or traditional telephony or both, and data connectivity, and Guest
Access application service, then configure your site based on the
"Converged small site (mixed-vendor environment)—reference topology
1" (page 23).
Linked SMB sites
Linked SMB sites offer two main types of solutions:
•
IP trunk linked sites
•
main and remote linked sites
In IP trunk linked site scenarios, both sites have a BCM telephony call
server and hence are independent. An H.323 IP trunk links the sites for
harmonized private dialing plans through branch office virtual private
Small and Medium Business Solutions Overview and Configuration Guide
network (VPN) tunnels. The linked SMB sites described in this guide are
verified for small deployment using BCM50 and larger deployment using
BCM200/400 in the following interconnected reference topologies:
•
"Interconnection of peer sites with incumbent routers (topology 1 with
topology 1)" (page 53)
•
"Interconnection of peer sites using BSR222 (topology 2 with topology
2)" (page 54)
•
"Interconnection of main and remote sites using BSR222 and
BCM200/400 (topology 2 with BCM 200/400)" (page 55)
In main and remote linked site scenarios, the main office hosts a BCM
telephony call server and is linked to remote offices where IP telephony
service is provided from the main office through branch office VPN
tunnels. Generally, these remote sites are very small offices where the
cost of deploying a locally hosted BCM telephony call server cannot be
justified. The linked SMB sites described in this guide are verified for small
deployment using BCM50 and larger deployment using BCM200/400 in the
following interconnected reference topologies:
•
•
Third step
After you determine which topology you are configuring, proceed to the
associated section of this guide, as follows:
•
•
•
•
"Interconnection of BSR222 and an incumbent router (topology 1 with
topology 3)" (page 56)
"Interconnection of main and remote sites using BSR222 (topology 2
with topology 3)" (page 58)
If you are configuring a smaller converged site—mixed vendor
environment, proceed to "Converged small site (mixed-vendor
environment)—reference topology 1" (page 23).
If you are configuring a smaller converged site—Greenfield and
infrastructure replacement, proceed to "Smaller converged site
(Greenfield and infrastructure replacement)—reference topology 2"
(page 37).
If you are configuring a smaller remote site—Greenfield and
infrastructure replacement, proceed to "Smaller remote site (Greenfield
and infrastructure replacement)—reference topology 3" (page 43).
If you are interconnecting multiple sites, proceed to "WANinterconnected
LAN reference topologies" (page 49).

Business Element Manager
The Business Element Manager is a Windows application that integrates
a Windows-like navigation panel with a simple network management
protocol (SNMP)-based discovery mechanism and various means of
product configuration depending on what features are supported by the
target product.
The Element Manager enables streamlined access to BES devices,
BAP120, and the BSR222 Web management screens. It also enables the
BES series management interface to support and access active content
such as port statistics measurement. These interfaces appear in the
Element Manager client window when you double-click the respective
devices from the Element Manager navigation panel.
A Web management interface also exists for the BCM50 and BCM200/400,
making seamless management of a converged SMB network possible.
Existing products17
Element Manager software can reside on any local area network
(LAN)-connected PC and be launched when required. Alternatively, a
remote PC running the Element Manager client located anywhere on the
Internet can securely manage devices on a target LAN through the BSR222
and VPN soft client.
The Element Manager is not required to manage individual products. You
can manage each product independently through its Web management
interface. The Element Manager simplifies access to multiple products and
enables active content where available.
Business Access Point 120 (BAP120)
The BAP120 is an IEEE 802.11a, 802.11b/g-compatible product that
provides transparent, wireless high-speed data communications between
the wired LAN and fixed or mobile devices equipped with either an 802.11a
or 802.11 b/g wireless adapter, or both. Any number of BAP120 products
can operate together in a network. This product can sit on a desktop or
mount inconspicuously on a wall or ceiling. The BAP120 is equipped with
a serial port, SNMP, and Web management interfaces compatible with the
Element Manager.
Small and Medium Business Solutions Overview and Configuration Guide
The BSR222 is a two-port router with a Cat5 wide area network (WAN)
connection and four 10/100 Mb/s LAN ports. It has roughly one-fourth the
footprint of a BCM50 and is powered by a local power adaptor through a
barrel plug. The router provides WAN connectivity to one or more Ethernet
switches and to the necessary client and branch tunnels to enable secure
remote access. The BSR222 is equipped with a serial port, SNMP, and Web
management interfaces compatible with the Element Manager.
Reference topologies and assumptions
This section outlines the assumptions for the reference topologies described
in this guide.
Small and medium-sized businesses typically use a third-party cable or
asymmetric digital subscriber line (ADSL) modem for high-speed Internet
access. The ISP must be able to provide a single static IP address to each
site. The BSR222 uses network address translation (NAT) to a private
IP address space and provides a firewall between the resultant private
LAN and the Internet. An internal DHCP server faces the private LAN.
All connected network equipment (BCM, BAP120, and BES) obtains the
associated IP address using DHCP from the router DHCP server.
Personal computers (PC), personal digital assistants (PDA), laptops, and
Nortel IP phones obtain private IP addresses from the same DHCP server.
Voice support is provided with Nortel IP phones, Voice Soft-Clients, and the
BCM communications server. IP phones receive IP addresses from the
BSR222. However, in a topology where a third-party router is present, IP
phones receive IP addresses from the BCM.
Nortel IP phones and soft phones run a proprietary stimulus protocol that
is terminated at the BCM. The BCM presents H.323 trunks to other sites
encapsulated inside VPN branch tunnels that are established between
pairs of sites. The BCM also mediates control and voice flows destined
for the local public switched telephone network (PSTN). A Nortel 2050
Voice Soft-Client runs on an IEEE 802.11e EDCA WMM-compatible
notebook computer or PDA connected by a wireless local area network
(WLAN) (BAP120). A second voice soft client (the Nortel MVC 2050)
tailored for a PDA also connects through a standard 802.11b WLAN. The
BAP120 supports IEEE 802.11e Quality of Service (QoS) tagging (for
example, EDCA/WMM interim QoS for multimedia) and traffic segregation
(SSID-to-VLAN mapping) for enhanced voice quality and security. Roaming,
such as handoff of data connections between access points, is supported.
The BSR222 performs secure routing functions and supports a combination
of 10 client and branch tunnels. The BCM50, Business Ethernet Switches,
BAP120, and BSR222 are all manageable using the Element Manager
application.
Small and Medium Business Solutions Overview and Configuration Guide
All reference topologies assume that each device on the subnet has its
SNMP client enabled.
IP addressing for SMB devices and DHCP
Nortel recommends using DHCP to obtain IP addresses for SMB devices
and end nodes (such as PCs and IP phones).
The SMB reference topologies 2 and 3 rely on a DHCP server running on
the BSR222 in the subnet (typically occupying address 192.168.1.1). SMB
referencetopology 1 relies on a DHCP serverrunning on a third-party router.
DHCP serves IP addresses dynamically to all devices and end nodes
connected to the subnet. As devices are connected to the subnet, they
take IP addresses from the DHCP pool from 192.168.1.2 to 192.168.1.127
inclusive.
If DHCP is not running on the subnet, all SMB devices are shipped with
factory-default IP addresses that exist within ranges of the subnet that
minimize IP address conflict.
The following table lists the default IP addresses, valid IP ranges, and
default DHCP status for all SMB devices.
