1.4 Design
Each switching module IPN-8U is a compact switch with eight subscriber kits with
Uk0-interface, and four FastEthernet ports for connecting to IP network. All Uk0-interfaces
are equipped with Power-over-U function – “phantom” power supply of subscribers with
automatic overload protection, which allows connecting digital subscriber devices by one
pair of wires for a distance of up to several kilometers, depending on the cable cross sec-
tion. The power supply function on each Uk0-interface is executed by a program, accord-
ing to the configuration data of IPN-8U. Connection of subscriber lines of Uk0-interfaces is
performed by screw terminals with a cross section of up to 2.5 mm2.
Ports of inbuilt FastEthernet switch are equipped with PoE function in compliance
with IEEE 802.3af Class 0, and can be used for direct connection of IP subscriber devices.
IPN-8U module is housed in 19" metal enclosure with the height of 1HU. On the front
panel there are four FastEthernet ports, fuse holders, sockets for power supply and con-
nection of digital subscribers. The two-color indicators located ibid represent user interfac-
es status, operation mode of the central processor, integrity of fuses and power circuits.
The available status modes of IPN-8U indicators depending on the mode of its operation,
are shown in Table 3.
IPN-8U module is fed from the external power supply source 48 VDC. The grounding
terminal for the enclosure is on the power supply connector.
