Introduction The Black Box DSL Discovery device is targeted at the organization of high-rate access to Internet or at the integration of LANs. The 2B1Q line encoding is used to transmit information over a twisted pair. The Black Box DSL Discovery device ensures organization of communication over one or two twisted pairs. The device provides transmission rates in the range from 192 Kbit/s to 4640 Kbit/s.
General information • High-speed symmetrical data transmission over one or two physical copper twisted pairs with the 135 Ohm impedance according to ETSI TS 101 135. • 2B1Q line encoding. • Line rate in the range from 192 Kbit/s to 2320 Kbit/s over every pair, up to 4.6M over two pairs. •...

informs the user about the status of the local device. The following four statuses are LOCAL(L) possible «blinking red» informs the user about malfunctioning of the modem’s hardware and software. In this case, the modem is out of order and should be submitted to the service center for being repaired.
Rules of connection settings It is necessary to stick to the following rules while configuring the modems: • One modem should be set in the “MASTER” mode and the other should have this mode disabled. Usually the “MASTER” mode is enabled on the provider or central office side because in this mode the modem can affect the connection parameters.
• launch the hyper-terminal operation program on the PC. For Rack Mount models • insert modem card to shelf • connect the modem using the “straight” Patch Cord cable to the hub through the HUB connector or to the PC through the PC connector. Only one device can be connected to modem jack at same time.
