IPN-8U Network Switching MODULE

All Uk0-interfaces are equipped with Power-over-U - "phantom" power
subscribers with automatic overload protection. Embedded Switch Ports
FastEthernet supports PoE according to IEEE 802.3af Class 0, and can be used for
connecting and powering IP subscriber devices.
IPN-8U contains firmware and configuration data, and
provides an opportunity for connected digital subscribers to communicate
directly with each other and with other subscribers of the decentralized IPN 1.1 system,
without using a special central or server, and also implements
control of connection priorities, communication and indication modes.
