Key Benefits
Compatible. Connect to any ISP supporting the industry-standard Point-to-Point Protocol (PPP). Integrated communications. The LAN Modem intelligently adjusts bandwidth to permit efficient use of the ISDN link, allowing simultaneous voice and data connectivity. High performance. Allows near instant call setup and teardown; provides throughput up to 512 Kbps with Multi-link PPP and data compression. Part of the award-winning OfficeConnect family. As business requirements change, add other functions such as high-speed networking, Internet access, remote access, or print-sharing capabilities. The OfficeConnect ISDN LAN Modem eliminates the cost and inconvenience of multiple phone lines. It lets you consolidate all of your office communications— as many as 25 computers and two telephones or fax machines— onto a single ISDN line. This smart, cost-efficient, and simple 3Com solution lets you have one office and one communications line. The 3Com OfficeConnect ISDN LAN Modem is so smart that it automatically assigns bandwidth around your telephone calls using Multi-link Point-to-Point Protocol (ML-PPP). Now you can talk on the phone while simultaneously sending or receiving data over the computer link. When you make or receive a phone call, the modem’s dynamic bandwidth allocation (DBA) feature reduces the data link to one channel. When your call is finished, the higher speed (two channel) connection automatically reinstates, providing your modem—and every computer on your LAN—with maximum data link capacity. The OfficeConnect ISDN LAN Modem also gives you the flexibility to connect to two different ISPs over the same ISDN line. Any of the computers on your LAN can be set up with a default connection. This gives you the freedom to select different ISPs for different types of access—for example, access from home or access to the office. It gets even better. With IP tunneling, small offices can affordably, easily, and securely share corporate resources, including e-mail, applications, intranet access, and files while using a single, shared Internet account. Top Throughput for Faster File Transfers, Lower Costs Compared to standard analog modem technology, Ethernet LAN and ISDN technologies will revolutionize your office communications—both locally and remotely. Because the OfficeConnect ISDN LAN Modem incorporates a network router, each connected computer can reach Ethernet transmission speeds of 10 Mbps, eliminating the computer COM port’s 115 Kbps bottleneck. What’s more, the OfficeConnect modem’s Internet transmission speeds are more than four times faster than those of standard analog modems. The OfficeConnect ISDN LAN Modem uses the ML-PPP to transfer large data sets over both ISDN B channels, dynamically assigning data channels as required. Moreover, the OfficeConnect ISDN LAN Modem supports standards-based data compression—the IETF Compression Control Protocol with LZS technology from hi/fn, Inc. It allows actual throughput from the LAN onto the 128 Kbps ISDN connection to reach effective speeds up to 512 Kbps. This increased throughput means decreased usage fees and waiting time for every user on your LAN. The OfficeConnect ISDN LAN Modem is the quick, easy, and affordable way to connect your entire office to high-speed ISDN communications.
