The Data Connect RM32-UI

The Data Connect RM32UI-AC modem shelf is designed for centralized network that require up to sixteen concentrated DCE V.3600UI-RM2 modem cards in a computer room, telephone closet or an industrial environment. The DCE RM32UI-AC modem shelf is constructed of heavy guage steel, plated for corrosion resistance. The modem shelf is comprised of dual power supplies, two levels of management within the Network Management System (NMS) via RS485 and/or RS232 ports on the backplane, the Network Management Controller (NMC), an area for one to sixteen modem cards, and a backplane for hardwiring the dial or leased lines, and area for connecting one AC power supply and DTE access via DB25F connectors.

The first level of network management only requires a rack. In this application, the NMC unit is responsible for the operation of the NMS. The NMC allows you to set up, control, and test any specific modem card in the same shelf. The NMC will amplify an audible alarm and visible LCD message through the operation of the front panel keys. The second level of network management is designed for multiple racks in a large size network. The network management requires a NMC that is composed of a computer and control units in “Daisy Chain” structure is responsible for the operation of the NMS. In this application, the structure can manage up to 130,000 DCE V.3600UI2 modem cards via 8, 126 RM32UI-AC modem shelves.

The DCE V.3600UI-RM2 modem cards and remote and the dual power supplies are swappable. The front panel controls internal DCE V.3600UI2 modem cards and remote V.3600UI, V.3600UI-DC, V.3600UI-DC24, and V.3600UI-DC12 standalone modems. The dual power supplies are fully redundant. The AC power supply operates at 90-260VAC, 47-63Hz with a power consumption of 180 watts.
