8 Channel Video Receive Unit with up to 9 Bi-directional
Data / Audio Channels plus Ethernet for a Dual Redundant
fibre ring - includes AMG NMS Network Management
The AMG3788BERN-DR is a rackmount eight channel video receive unit designed to receive up to 8
video signals from a dual fibre optical fibre ring with Dual Redundant operation. It also provides 9
bi-directional data/audio channels via a low speed data interface, plus full duplex 100BaseT Ethernet
connectivity around the ring. Eight of the data/audio channel interfaces, whether RS-232, RS-422,
RS-485, 20mA, TTL, Contact Closure, Lonworks or Audio, are defined at manufacture by the addition
of daughter boards fitted onto the Data Expansion Board B.
The AMG3788BERN-DR is designed to plug into an AMG2005 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 AMG3788BERN-DR is designed to operate with up to eight AMG3717BE-DR single channel
video insert units. Each receiver will 'drop off' up to eight video channels which are being transmitted
around the fibre ring. The AMG3788BERN-DR may also be used with other combinations of single,
dual or four channel video and data insert units.

This signal will be repeated around the ring to get back to this AMG3788BERN-DR on the secondary route. As the primary input is not present on this unit, the data signal will now be taken from the secondary optical input. Thus maintaining integrity of the data transmission. - Page 5 The AMG3788BEN-DR or rackmount AMG3788BERN-DR is designed to be connected in a ring or point to point system. In a ring system, single, dual and four channel insert units respectively can be combined to make up an 8 channel video transmission system as illustrated below.

Page 7: 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. -
Page 8: Data And Audio Channel Configuration
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 9: Data Interface Connections Channel A
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. -
