28.8/56 (28.8K bps/56K bps) This composite link speed indicator displays the baud rate of the internal modem (28.8) or DSU (56K). The type of composite link device is indicated by which of the EXT, MDM, DSU, or TA indicators lights.

DataTalker Owner’s Manual

28.8/56 (28.8K bps/56K bps) This composite link speed indicator displays the baud rate of the internal modem (28.8) or DSU (56K). The type of composite link device is indicated by which of the EXT, MDM, DSU, or TA indicators lights.

This indicator lights steadily when a DSU is installed. It has three states when an internal MMH2834 modem is installed (ON, flashing seven or eight times per second). When the LED is ON solid, it indicates a link speed of 33.6K bps. When the LED flashes eight times with a one second off time, the link speed is 31.2K and when it flashes seven times with a one second off time, the link speed is 28.8K bps.

RTS/DTR (Request to Send/Data Terminal Ready) This dual function indicator functions as a Request To Send (RTS) indicator when a DSU is the internal composite link device or as a Data Terminal Ready (DTR) indicator when an internal modem or an ISDN terminal adapter is the composite link device.

NS/DBUP (No Signal/Dial Backup) This dual function indicator functions as a No Signal (NS) indicator when a DSU is installed. It lights when no signal at all is received from a DDS line or when the signal is too weak for normal operation. When a 33.6K bps modem is selected as the composite link device, it functions as a Dial Backup (DBUP) indicator, lighting when the modem is in dial backup mode.

OOS/OH (Out of Service/Off-Hook)This dual function indicator functions as an Out Of Service (OOS) indicator when an internal DSU is installed. It lights when an out of service signal is detected by the telco. When a 33.6K bps modem is selected as the composite link device, it functions as an off-hook (OH) indicator, lighting when the modem is active (off-hook).

2B (2B Operation) If an ISDN terminal adapter is installed, this indicator lights when the two ISDN B channels are operating as a single, high-speed, 128K bps channel. The indicator is off when one B channel is operating.
