By using DAMA technology the number of separate nodes that can use a limited pool of circuits can be greatly increased at the expense of no longer being able to provide simultaneous access for all possible pairs of nodes. A five-channel DAMA network can only have five simultaneous conversations but could have any number of nodes. A five-channel PAMA network permanently supports five simultaneous conversations, with channel ownership remaining with their permanently assigned nodes even when idle.
By employing DAMA technology, the quantity of distinct nodes that can utilize a restricted pool of circuits can be significantly enhanced at the cost of no longer being able to offer simultaneous access for all potential pairs of nodes. A five-channel DAMA network can only support five concurrent conversations but could have any number of nodes. A five-channel PAMA network consistently maintains five simultaneous conversations, with channel ownership remaining with their permanently assigned nodes even when idle.
