Today more than half of all small business employees are information workers. Lawyers, writers, consultants, and engineers are all examples of people who work with information as a fundamental part of their job. While having the most up-to-date information is critical for these people, the costs associated with accessing that information must also be managed. As information-based businesses become increasingly diversified and competitive, the demand for cost-effective high-speed access to rich information resources will continue to increase.
Integrated Services Digital Network (ISDN) provides information workers with the power to access the resources they need quickly and inexpensively. ISDN is here today, and it provides the enabling technology for new network applications such as telecommuting, electronic commerce, and high-speed access to on-line services and the Internet. Because ISDN is a digital service, information can be transmitted up to ten times faster than is possible using standard analog modems. And because ISDN uses the same copper wiring as the existing telephone network, most buildings and residences are ISDN-ready today.
ISDN gives information workers the power they need to share resources and exchange data, regardless of their physical location. As businesses strive to improve productivity, control real estate and travel expenses, and facilitate effective communication, high-speed access to information will be essential to remain competitive.
CiscoPro(TM) products from Cisco Systems offer comprehensive ISDN access solutions for growing businesses and individual users. All CiscoPro products combine the benefits of Cisco's industry-leading networking technology with the convenience of tailored solutions. CiscoPro delivers an outstanding value in products that are easy to install, use, and manage. With a 50% share of the LAN-to-LAN access router market, Cisco has the technology and experience necessary to provide your business with world-class solutions to your networking needs.
For example, CiscoPro products can help you control the overall cost of ownership of your ISDN network. Wide-area network (WAN) charges represent the most costly component of most network installations, followed closely by the cost of providing support for mission-critical network services. While CiscoPro products offer the industry's most advanced features for optimizing the use of expensive WAN bandwidth, these products have also been designed to be easy to install and manage. Access That Works means that you can stay focused on your business, not your network.
The CiscoPro 750 family of access routers gives you everything you need to take advantage of the power of ISDN. The CiscoPro 750 family provides an affordable ISDN access solution that is complementary to the CiscoPro 1000 family. While the CiscoPro 1000 family is ideal for connecting small branch offices to a central site, the CiscoPro 750 family is tailored for telecommuters, small professional offices, and home offices. By providing full routing support for IP and IPX protocols, the CiscoPro 750 family allows maximum flexibility for companies with small networks that wish to start with a simple bridged topology of Cisco 750 family products and implement IP and IPX routing over time.
The CiscoPro 750 family also features an optional analog telephone interface that allows devices such as standard telephones, fax machines, and modems to share the ISDN BRI line, eliminating the need for multiple telephone lines or expensive ISDN telephones. A built-in Network Termination 1 (NT1) device is also available for customers who demand an all-in-one solution for ISDN access. To simplify the process of using CiscoPro 750 family routers, each model includes the Cisco ConnectPro software, a Microsoft Windows-based application that makes CiscoPro 750 family routers easy to install, configure, and manage.
Table 1. The Three Models in the Cisco Pro 750 Family
| Model | CPA0751 | CPA0752 | CPA0753 |
|---|---|---|---|
| Description | Multiprotocol ISDN Access Router | Multiprotocol ISDN Access Router | Multiprotocol ISDN Access Router |
| Ethernet | 10BaseT, 10Base2 | 10BaseT, 10Base2 | 10BaseT, 10Base2 |
| NT1 | No | Yes | Yes |
| Analog Telephone Interface | No | No | Yes |
The CiscoPro 751 multiprotocol ISDN access router is a low-cost solution for telecommuters, small offices, or home offices with Ethernet LANs. The CiscoPro 751 is the product of choice for international users or users who prefer to use an external NT1 device for connecting to the ISDN network.
The CiscoPro 752 includes a built-in NT1 device to provide an all-in-one solution for ISDN users in North America. The CiscoPro 752 also provides an external ISDN BRI S/T port to support additional ISDN devices such as digital telephones or video codecs.
The CiscoPro 753 includes both a built-in NT1 and an analog telephone interface. Using Cisco's call priority feature, the CiscoPro 753 can be configured to drop one ISDN B channel to accept an inbound call if both channels are being used for data. Users can enter the initial configuration for the CiscoPro 753 by using a standard touch-tone telephone.
The CiscoPro 750 family offers the following features:
The CiscoPro 750 family offers a comprehensive set of software features tailored specifically for the needs of the telecommuter or small office user. All CiscoPro 750 models feature both IP and IPX routing and transparent bridging, as well as advanced features normally found only in more expensive internetworking products. In addition, the CiscoPro 750 family is interoperable with Cisco Internetwork Operating System (Cisco IOS(TM))-based routers such as the CPA4500 using Multilink PPP in IP or IPX routing environments.
The standard version of the CiscoPro 750 family supports up to four Ethernet devices on the LAN side of the router. The Remote Office (RO) version is available for users who require support for more than four LAN devices.

The CiscoPro 750 family gives employees who work from their homes transparent access to network servers and other resources on their companies' office LANs. IP and IPX routing support the most common LAN protocols found on today's networks, while transparent bridging provides a solution for other network environments. Combinet Connection Manager provides security, call management, device configuration, and accounting functions when used with the Combinet 900 or CiscoPro 750 family products at the central site, and CiscoVision provides a standards-based SNMP network management and monitoring solution.

Figure 1. Telecommuting Solution
The CiscoPro 750 family allows small offices and home offices to connect easily and inexpensively to customers, vendors, service bureaus, and other small offices. For example, a small publishing firm with several large clients can use a CiscoPro 750 family router to connect transparently to customer sites for transferring large image files quickly and efficiently. CiscoVision provides SNMP network management functions, and TACACS+ provides a centralized solution for authentication, authorization, and accounting.
