LLC Armtel;

−digital subscriber IP units with Ethernet-interface and ACM-IP modules pro-

duced by LLC Armtel;

−SIP telephone sets and other equipment of the third party manufacturers,

fed by PoE according to standard IEEE 802.3af-2003 Class 0;

−digital recording units IP with Ethernet-interface;

−data transmission equipment with interface Fast Ethernet (10/100Base-T).

IPN-8U contains firmware and configuration data that enables to connect up to eight

digital subscriber units with Uk0-interface to IP network. Connected to IPN-8U digital sub-

scribers can communicate with each other and with other subscribers of IPN 1.1 decentral-

ized system directly, without using allotted central exchange or server, and also manage

connection priorities, communication and display modes.

−switching of connected digital subscriber units with

Uk0-interface between themselves and other subscribers of IPN communi-

cation system in simplex mode according to configuration;

−iIndication of busy subscriber, incoming and outgoing calls, second incom-

ing call, unanswered call on the keys of the digital units with Uk0-interface;

−activation of built-in relays of DW\DW Ex units and ACM control lines

(except for group calls);

−bandwidth – 6,8 kHz;

−«phantom» power supply of the subscriber unit using PoU (Power-over-U)

function with load amperage of up to 300 mА.

Power consumption of IPN-8U:

−IPN-8U with disconnected Uk0-interfaces and Ethernet ports – 6,4 W;

−IPN-8U with connected DIS via Uk0-interface, without “phantom” power

supply and disconnected 4 Ethernet ports – 7,5 W;

−IPN-8U with connected 4 Ethernet ports and disconnected subscribers

on Uk0-interface – 8,5 W;

−IPN-8U with connected 8 DIS units via Uk0-interface, without “phantom”

power supply and connected 4 Ethernet ports – 9,1 W.

−IPN-8U is a PoE power supply source (injector), which meets the requirements

of standard PoE IEEE 802.3af-2003 Class 0 (see Appendix А). Maximum pow-

er, given by1 Ethernet port when using the PoE technology is 15.4 W.

Maximum power on one port of Uk0-interface when using «phantom» power supply

is 15 W.

The product ensures connection / disconnection of subscriber units without power

off and necessity to reboot.

To connect subscriber devices with Uk0-interface to the IP network, the subscriber

connection cable is used, which is included into the scope of the module supply. The ex-

ternal appearance of the subscriber connection cable is given in Appendix B.

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.
