What Can the OfficeConnect Gateway do? 1 - 5

What Can the

OfficeConnect

Gateway do?

The 3Com OfficeConnect Gateway family of IADs offers a complete

integrated voice and data solution ideally suited for small businesses. The

product family lets small and midsize businesses maximize the economy

of their DSL broadband Internet connections by transmitting voice and

data across wide area networks (WANs). These products function as

integrated access devices (IADs) that sit at the edge of the business

network.

The OfficeConnect Gateway combines signals from business phone

systems with data from PCs and other computers, and merges them for

transmission to the Internet and to the public switched telephone

network (PSTN). The OfficeConnect Gateway supports voice features

such as call forwarding, caller ID, and three-way calling, plus

data-networking features such as VPN initiation and termination, as well

as encryption and advanced fire wall filtering. In addition, you can add

the 3Com OfficeConnect Gateway Voice Expansion unit to either of the

OfficeConnect Gateway base units so that you can scale to 4,8 or 12

simultaneous voice lines by combining different units.

■ By integrating voice and data over DSL broadband, the OfficeConnect

Gateway family greatly reduces the costs associated with leasing

multiple telephone lines

■ The OfficeConnect Gateway Data-only base unit contains a built-in

voice expansion interface so users can choose to add voice capability

whenever their application needs change.

■ The OfficeConnect Gateway family employs voice-over DSL (VoDSL)

technology, plus ATM QoS (Quality of Service) support with dynamic

bandwidth allocation, to optimize high voice quality.

■ Easy-to-use Web-based interface and HTML/SNMP/Telnet access

simplify local management and facilitate remote configuration and

management.

■ Robust VPN support includes tunnel initiation/termination for up to 16

tunnels, plus hardware-supported IPSec processing to speed VPN data

encryption.

■ Continuous high-speed Internet and remote LAN access are delivered

via the DSL interface and autosensing 10/100 BASE-T-LAN port.

■ The OfficeConnect Gateway supports full-featured TCP/IP routing,

advanced address translation, and multiple transport protocols,

GATEWAY

including PPP over Ethernet (PPPoE), PPP over ATM (PPPoA), and

multi-protocol encapsulation over ATM.

Virtual Private

Networks (VPNs)

The full-featured virtual private networking (VPN) functionality of the

OfficeConnect Gateway gives remote offices and telecommuters secure

access to corporate LANs. VPN support is provided through the initiation

and termination of IPSec, PPTP, and L2TP tunnels. The OfficeConnect

Gateway supports up to 16 simultaneous VPN tunnels. Dedicated

hardware acceleration provides high-performance IPSec tunnels.

VPN technology is based on a tunneling strategy. Tunneling involves

encapsulating packets constructed in a base protocol format within some

other protocol. For VPNs that are run over the Internet, packets in one of

several VPN protocol formats are encapsulated within IP packets.

Voice over DSL VoDSL combines asynchronous transfer mode (ATM) with DSL service to

deliver voice and data services over a single copper line. The different

attributes of DSL technology and ATM functionality work well together.

DSL links are ideally suited for voice and data integration. ATM can

simultaneously carry voice and data traffic.

VoDSL is usually provisioned as an overlay to a DSL broadband access

network. A VoDSL implementation requires several additional

components. A voice gateway resides at the service provider’s central

office near a PSTN (Public Switched Telephone Network) telephone switch

(Class 5 Switch) and serves as the bridge between the circuit-based voice

switch and the packet-based DSL network. An IAD, located at each

customer premises, is connected to the DSL circuit. The device manages

voice services via analog POTS ports and Internet service through an

Ethernet port. Existing telephone and LAN equipment interconnect with

the IAD.

The IAD converts LAN and voice data to ATM cells and transmits the data

over the DSL link to the service provider’s network. The DSLAM

aggregates traffic coming from individual lines; encapsulated voice traffic

is sent to the voice gateway and the data traffic is carried as packet or cell

to its final destination, an ISP or corporate network. The voice gateway

converts the voice traffic to conventional voice signals and sends it to a

Class 5 voice switch.

An example of a typical VoDSL implementation is shown in the following

illustration.

Typical VoDSL Implementation

Small-business VoDSL solution

The 3Com OfficeConnect Gateway delivers multiple toll-quality voice

lines, high-speed Internet, and corporate LAN access cost-effectively to

small businesses. Plus, it’s easy to add other popular OfficeConnect

solutions to the network, including switches, hubs, firewalls, network

storage servers, wireless access points, and Internet servers. The following

illustration shows an example of a small-business VoDSL implementation.

OfficeConnect Gateway Integration with an NBX system or

traditional PBX/Key system

The OfficeConnect Gateway can easily be integrated with a 3Com NBX

25 Communications system or traditional PBX/Key system. The 3Com

NBX 25 communications system’s analog ports are plugged into the four

FXS ports of the OfficeConnect Gateway base unit. By combining these

systems, users have access to toll-quality voice services as well as the

feature-rich call processing function of the NBX system. The

OfficeConnect Gateway works similarly with either a PBX or Key system.

The following illustration shows an implementation to support an NBX

system.
