An optional fan module for the ac carriers is available to provide forced air cooling to dissipate heat generated within the carrier. It is recommended that fully configured carriers and cabinets be installed with fan modules to extend the life of the equipment. Guidelines for fan module provisions are listed in Table
An SDCP is required for initial installation and for testing of 3600 Series DSUs, 3151 T1 CSUs, and 3161 T1 DSU/CSUs and their options. Models 3811 and 3911 dial/lease modems can be installed using the SDCP or AT commands from the attached DTE. The SDCP, in conjunction with the SDU, allows up to eight COMSPHERE 3000 Series Carriers to be managed from one control panel. Models 3551, 3611, and 3616 DSUs and Models 3811 and 3911 dial/lease modems are managed by either the COMSPHERE 6700 or 6800 Series Network Management System (NMS).
Within the carrier, the first slot (Slot 0) is reserved for the SDU. The SDU provides the required interface that daisy chains carriers together for NMS and/or SDCP control. In a cabinet configuration, connectivity between the DSUs in the individual carriers allows control of compatible units in the cabinet through a single NMS interface, a single SDCP, or both.
On the rear of the carrier is a pair of
