Network arrangement having separately selectable signature for each signal entering system from external synchronization source
First Claim
1. A network arrangement, comprising:
- a communication system employing message-based synchronization and comprising a plurality of nodes interchanging signals containing information about the priority of each respective signal in the internal synchronization hierarchy of said communication system;
at least one external network employing a synchronization method different from the message-based synchronization employed in said communication system, said at least one external network being connected to said communication system and providing at least one external synchronization source for said communication system; and
said communication system being arranged to assign each external signal entering said communication system from said at least one external synchronization source with a selectable standard signature indicating an individually selectable priority of each said external signal with respect to internal signals in said communication system.

Abstract
A network arrangement including a system employing message-based synchronization and having a plurality of nodes interchanging signals containing synchronization messages with information about the priority of the respective signal in the internal synchronization hierarchy of the system. In order that the system can, even as far as synchronization is concerned, be connected to an external device or network to which the message-based synchronization employed in the system is unknown, a signal entering the system from an external synchronization source is assigned a selectable standard signature indicating the priority of the signal from the external synchronization source with respect to the internal signals of the system, the priority indicated by the signature being selectable separately for each signal entering the system.

7. The network arrangement, comprising:
-
a communication system employing message-based synchronization and comprising a plurality of nodes interchanging signals containing information about the priority of the respective signal in the internal synchronization hierarchy of said communication system; an external synchronization source connected to more than one of said nodes in said communication system, said external synchronization source being incompatible with said message-based synchronization employed in said communication system; and each one of said more than one nodes being arranged to assign external signals entering said communication system from said external synchronization source a same standard signature indicating the highest selectable priority in the internal synchronization hierarchy in said communication system. - View Dependent Claims (8)

9. The network arrangement, comprising:
-
a communication system employing message-based synchronization and comprising a plurality of nodes interchanging signals containing information about the priority of the respective signal in the internal synchronization hierarchy of said communication system; an external synchronization source connected to at least first and second one of said nodes in said communication system, said external synchronization source being incompatible with said message-based synchronization employed in said communication system; and said first one of said nodes being arranged to assign external signals entering said communication system from said external synchronization source a first selectable standard signature indicating the highest selectable priority in the internal synchronization hierarchy in said communication system; and said second one of said nodes being arranged to assign external signals entering said communication system a second selectable standard signature different from said first standard signature and indicating a selectable priority lower than said highest selectable hierarchy. - View Dependent Claims (10)
