Technical Field of Application This disclosure relates to public telecommunication in general and, more particularly, to a mechanism to provide pooled resources remote-located in nodes with decomposed (decentralized) architecture. State of the Art Monolithic nodes provide resources either permanent assigned to the circuits or centralized in a common pool. When introducing nodes with a decomposed (decentralized) architecture, certain resources can no longer be provided in a centralized and common pool; e.g. Echo Canceller with a limited tail path length. The straight forward solution would then be to provide the resources permanent assigned to the circuits. This however is not the most economical way of providing the resources. Another problem is the synchronisation of the status of the remote resources due to the propagation delay of any information exchanged between the remote location and the host; in case of satellite connections or packet based communication the propagation delay can be in the order of several 100ms.
