It's taken nearly a decade, but the high-capacity Synchronous Optical Network standard is gradually replacing the older NADH infrastructure. While industry pundits debate the future of enterprise networking, a few […]

A T-1 is a digital circuit that can carry up to 24 64 kbps voice or data channels (DS0s). T-1 can travel over two pair of UTP, a strand of […]

Your clients' bandwidth needs are growing. You can make the most of the bandwidth your clients have, while providing them a migration path to faster services. Your clients know they […]

In conventional telephone terms, a T-1 circuit carries up to 24 simultaneous 64 kbps voice conversations -- a total of 1.544 Mbps capacity. T-1 can travel over many different kinds […]

Tips and New Technologies to Make Your Data Flow More Smoothly Constructing a WAN (Wide Area Network or 'enterprise-wide network') involves major decisions on the part of any company, but […]

Many T-1 service providers are shifting from traditional point-to-point dedicated lines to VPNs, or Virtual Private Networks. A VPN is a hybrid network that serves both private and public facilities. […]

This was our most explosive shootout yet. Only two vendors, FastCorem and Magnalink, came to set up their data compression units at N.Y. Telephone's Customer Presentation Center. Yet, despite our […]

Education needs of western Nebraska are complicated by broad geographic areas and a population thinly scattered across the region. Some population concentration exists around Chadron, Alliance and communities sprinkled along […]

Have you ever noticed just how far away your remote sites are when you transfer files at 9.6 Kbits/sec? Or worse, express mail floppy disks from coast to coast? We're […]

With all of the excitement surrounding the high end of the T1/T3 multiplexer market, the quieter, traditional T1 market is sometimes overlooked. The whiz-bang glitz that once surrounded these technologies […]

ADC KENTROX/DataSMART T1 and 45 SMDSU The DataSMART T1 and 45 SMDSUs provide subscriber access to the switched multimegabit data service (SMDS) at T-1 and T-3 rates. SMDS offers a […]

Distributed computing and the increases in bursty data traffic resulting from it have led to enhanced services for nearly ubiquitous highspeed connectivity. Over the past five years, T1 and T3 […]

Over the past 10 years, Phillips Communications & Equipment Charlottesville, VA - 804-985-3600), a secondary market company, has provided its clients with practical information that clarifies issues associated with buying […]

As the market for digital wideband products and services has evolved, so has the market for equipment to keep all of these networks running. Even though the carriers provide excellent […]

Multiplexing and switching products are generally considered the 'heart' of widebrand networks. In fact, there are so many of these products that they are broken out into separate tables. In […]

Even though we sometimes ignore this factor, we mus remember that the network exists to meet current computing needs. Computing networks should not be overly affected by what we think […]

The basic building block of a corporate internetwork is the local area network (LAN). The LAN provides the basic connectivity between computer devices in the same local area, such as […]

Hospitals deal as much with information as they do with people. The need to administer their data efficiently and still keep an eye on the bottom line is spurring them […]

T-1, the basic 24-channel 1.54 Mbps pulse code modulation system used in the United States, was developed as a transmission system to carry switched trunks and special service circuits between […]

Traditionally, the largest users of data communications test equipment have been the RBOCs, their Baby Bells and common longdistance carriers (AT&T, MCI, Sprint, etc.). Today, however, another group is making […]

Although the devices listed in Table 6 may be considered to be specialty devices today, they are in no way less important than the devices in the other tables. In […]

Table 7 lists a number of suppliers for wideband digital services, In the post-deregulation era, competition is increasingly intense and the variety of services offered is likewise increasingly complex In […]

While not as complex as the typical T1 multiplexing system, the basic CSU (channel service unit) is just as integral a part of the T1 network. Sometimes referred T1 mode […]

Over the past decade, digital wideband technology has become the preferred method of wide area networking for the majority of corporate America. The reason is simple: it's cheaper! The carriers […]

Multiplexing and switching products are generally considered the 'heart' of wideband networks. Table 1 lists suppliers of most of these types of systems broken into a few general categories. We […]

Low-bit-rate voice has user benefits but what is is future? Low bit rate voice--the technology of transmitting voice conversations over digital facilities with far less than the traditional 64-kbps per […]

Fast packet solves bandwidth-hungry data needs Fast packet--the hot new technology for public and private wideband networks--has sent shockwaves throughout the traditional T1 industry. This excitement stems from fast packet […]

Diagnostic tools target T1, LAN, ISDN needs At the center of today's communications test equipment market are three driving forces: the proliferation of T1 circuits, the growth of ISDN, and […]
