COMSPHERE DualFlow Data Service Units

•Diagnostic Control Panel control. The

Model 3615 DSU is controlled from its diagnostic control panel (DCP). The diagnostic control panel for the Model 3616 DSU, called a shared diagnostic control panel (SDCP), is installed in the

3000 Series Carrier. Both control panels display information about the DSU on 2-line, 16-character liquid crystal display (LCD) and through light-emitting diode (LED) status indicators.

NOTE

Except where a distinction is made, the term DCP refers to both types of diagnostic control panels, the DCP or the SDCP.

For more information about the 3000 Series Carrier or the SDCP, refer to the COMSPHERE 3000 Series Carrier, Installation Manual. For more information about the 6700 or 6800 Series NMS, refer to your NMS documentation.

DBM Features

DualFlow DSUs are ordered with one of the following features:

•V.32bis 14.4 kbps dial backup module (DBM)

•2-Wire Switched 56 DBM

•4-Wire Switched 56 DBM

Refer to the appropriate section for specific DBM features.

V.32 DBMs

The V.32bis 14.4 kbps dial backup module (referred to as V.32 DBM throughout this guide) is attached to the DSU. The V.32 DBM provides the following features:

•Multispeed nondisruptive point-to-point connections. The DBM provides point-to-point service over the 2-wire dial network. Backup rates available are 2.4, 4.8, 9.6, 12.0, and 14.4 kbps. DBM and DDS connections can be active at the same time.

•Independent operation. Although the DBM is installed on the DSU, the two are configured separately and most tests can be run on either independent of the other (e.g., you can run a test on the DBM while a test is running on the DSU).

•Security. There are four levels of call setup security: None, Password, Callback, and Alarm. With Alarm, the DBM only answers incoming calls when an alarm is detected on the DDS line.

•Management control. Dial backup can be initiated from a 6700 or 6800 Series NMS, the DSU's DCP, or it can be initiated automatically by the DSU-DBM.

•DTR control setup. When configured for DTR call control (DTRCallCon: Orig) backup, the DSU-DBM initiates dial backup when the DTE raises data terminal ready (DTR) to the DSU-DBM.

•Rate Adaption. With this feature, the DSU-DBM can adapt its data rate to a low-speed application while operating over a higher speed switched circuit.

•Port Async/Sync. The port asynchronous-to- synchronous feature makes it possible to send asynchronous data over the synchronous network.

•Nondisruptive Diagnostics. When set up to use nondisruptive diagnostics, the local DSU-DBM sends diagnostic data over the dial connection without interrupting or disrupting customer data.

•Full tributary diagnostics. The DSU-DBM supports a full complement of diagnostic tests and commands when a call is established on a backup line. Diagnostics can be addressed to and sent to a tributary from a 6700 or 6800 Series NMS workstation, or from the DCP of a control DSU.
