AMG3782RN-DR-SF

Instruction Manual

8 Channel Video Receive Unit for a Dual Redundant Single

Fibre Ring - includes AMG NMS Network Management

Interface

The

AMG3782RN-DR-SF

is a rackmount eight channel video receive unit designed to receive 8 video

signals from a singlemode optical fibre ring with Dual Redundant operation.

The

AMG3782RN-DR-SF

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

AMG3782RN-DR-SF

is designed to operate with

AMG3741-DR-SF

or rackmount equivalent

AMG3741G-DR-SF

four channel video insert units. It may also be used with other combinations of

single, dual and four channel video insert units.

An

AMG3782RN-DR-SF

receive unit will 'drop off' up to eight video channels which are being

transmitted around the fibre ring from up to eight single channel insert units, or from an equivalent
combination of multi-channel insert units.
