Product Highlights: • Custom VLSI technology yields superior performance and reliability • Attractive DeskTop enclosure saves office space in standalone installations • Advanced design ensures ease of installation and use • Simple option selection without complicated programming Description
Superior Performance
Optimum data throughput is ensured by a sophisticated compromise equalizer, for immunity to impairments normally encountered with unconditioned voice grade facilities. A soft transmit carrier turnoff virtually eliminates the problem of erroneous data bits that can affect polled applications. And the anti-streaming timer protects against the potential disruption caused by faulty, "streaming" terminals. In short, you just can't get more accurate transmission than with the DeskTop 202. Highest Reliability
As the most power efficient modem in its class, the DeskTop 202 can therefore save you even more in operating expenses. Plus, there's even an on/off switch for when the modem is not in use. Easy to Use The DeskTop 202 options are set using a switch bank accessible from the outside of the enclosure. While the switches determine things like RTS/CTS delays and constant or controlled carrier selections, other parameters have built-in default values to satisfy most user needs. We know that bringing up a network can be difficult, so we've made it simpler for you. Powerful Diagnostics
All tests may be initiated by front panel switches and monitored through easy-to-read LED displays. ANALOOP and RDL can also be controlled from the terminal equipment (DTE) interface. Finally, the DeskTop 202 has a selectable 10-minute abort timer to prevent inadvertently locking the modem in test mode for extended periods of time. The Uncluttered Desk
