Question
What is the function of the express channel interface?
A. It enables the high speed route for all channels passing through that interface.
B. It drops high capacity channels in the local node.
C. It passes all the channels not terminated in the local node through the downstream node.
D. It enables the high speed route for all channels terminated in the local node.
Answer
C. It passes all the channels not terminated in the local node through the downstream node.
Explanation
The express channel interface serves an important purpose in Nokia network nodes. Its main function is to provide a high-speed route for any channels that are not being terminated (i.e. dropped off) at the local node. Rather than processing these non-terminated channels locally, the express interface passes them directly through to the next downstream node in the network. This allows channels that don’t need to be handled at the current node to bypass local processing and continue on to their destination nodes efficiently.
In contrast, any channels that are destined for the local node get terminated there and do not pass through the express interface. The express interface also does not automatically enable high-speed routing for all channels, only non-terminated ones. Its purpose is to optimize network routing and throughput by separating express and local channel traffic.
So in summary, the key role of the express channel interface is to pass through non-terminated channels to the next node, enabling efficient end-to-end routing across the network.
