Data Receive Unit with Ethernet plus one Bi-directional
Data Channel and eight Bi-directional Contact Closure
Channels for a Dual Redundant Multimode Fibre Ring -
includes AMG NMS Network Management Interface
The AMG3608BERN-DR-SF is a rackmount data receive unit designed to transmit and receive 1 bi-
directional data channel plus 8 bi-directional contact closure channels and provide full duplex
100BaseT Ethernet connectivity with up to 8 AMG3603B5E-DR-SF or AMG3603B5ER-DR-SF
rackmount equivalent insert units over a dual redundant multimode optical fibre ring. The data channel
is a multi-drop RS-485 link, each contact closure channel is point to point with the corresponding data
insert unit.
The AMG3608BERN-DR-SF is designed to plug into an AMG2009 or AMG2015 subrack, which in turn
fits into a 19" rack system. It also includes an AMG Management Interface to allow Management of the
system using the AMG SNMP enabled Management software.
The AMG3608BERN-DR-SF is designed to operate with up to eight AMG3603B5E-DR-SF data insert
units. Each receiver will 'drop off' one RS-485 multi-drop channel plus up to eight individual contact
closure channels which are being transmitted around the fibre ring.

Page 4: Introduction
1550nm and the secondary channel on 1310nm. The AMG3608BERN-DR-SF receives and drops off data, contact closure & Ethernet signals transmitted from up to eight AMG3603B5E-DR-SF transmit units. It then inserts data, contact closure & Ethernet signals onto the outgoing optical signal As each unit regenerates the optical signal, the optical dynamic range between each optically connected node is 17dB. - Page 5 For the scenario shown below data would now be lost from units 1 and 2 as there is now no physical connection between the transceivers and the receiver. However operation of units 3 and 4 to 8 remain fully functional. AMG Systems Ltd. reserves the right to make changes to this Page 5 of 16 AMG3608BERN-DR-SF Instruction document without notice.

Bank B carries up to 8 channels of data / audio, the physical interface of which is determined by fitment of AMG data or audio daughter boards onto the B Channel data expansion board slots. -
Page 8: Bank B Data
Data and Audio Channel Configuration The data expansion board slots are accessed by removing the AMG unit from its case. A data channel is active when a daughter board is installed in the required data channel slot. Each data interface board enables one bi-directional channel. -

Page 11: Ethernet Operation
Ethernet Operation In order for the AMG system to transmit Ethernet signals, an onboard RJ45 Ethernet interface or X16003 Ethernet interface adaptor should be fitted to all units in the ring. The Ethernet interface can operate at either 10Mbits/s half duplex, or 100Mbit/s full duplex. When all the Ethernet interfaces around the ring are operating at 100Mbit/s full duplex the system behaves as a multi-port repeater. -
