BLACK BOX MD1000A Analog Sync/Async V.36 Modem - Dial-up or Leased-Line, AC Power
The BLACK BOX MD1000A is a high performance V.34/V.42bis data and fax modem. It allows users to transmit critical applications at 33.6 kbps in synchronous and asynchronous environments, and is capable of throughput rates up to 230.4 kbps. BLACK BOX's technology leadership continues to offer exceptional speed, features and versatility for all networking needs.
Data Modem Overview
Compliant with ITU-T V.34, the MD1000A incorporates advanced technology that enhances operation on less than-ideal transmission lines. These include: echo canceling, automatic adaptive line equalizing, trellis coding techniques, adaptive baud rate selection, transmit pre-emphasis, automatic transmit power selection, constellation shaping, and non-linear encoding and pre-coding.
The MD1000A LCD front panel gives you interactive fingertip control of option selection and modem configuration. The 32-character display and three pushbutton keys let you scroll through a complete menu of option choices, displaying the currently selected options and prompting you for changes. The MD1000A is also easily configured by AT commands or by the remote configuration feature. Nine preset factory option configuration sets simplify set up for most standard applications.???????
