Description

The Data Connect RM16M27-UI modem shelf is designed for centralized
network that require up to sixteen concentrated DCE V.3600UI-RM
modem cards in a computer room, a telephone closet or an industrial
environment. The DCE RM16M27-UI 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, an area for connecting AC or DC
power and DTE access via DB25F connect ors.
The first level of network management only requires a rack. In this application, the NMC unit is responsible for the
Fully Redundant Power Supplies
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 a visible LCD message through the operation of the front panel keys.
The second level of network management is designed for mulitple racks in a large size network. The Network
Management requires a NMC thta 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.3600UI modem cards via 8126 RM16M27-UI modem shelves.
The DCE V.3600UI-RM modem cards and the dual power supplies are hot swappable. The front panel controls
both internal DCE V.3600UI 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.
