Channel bank

Do you remember playing with a toy phone that had different buttons for different people you could talk to? Well, a channel bank is kind of like that toy phone, but for real phones. Except instead of buttons for specific people, it has channels that can hold phone calls between different phones. Think of each channel as a separate road that cars (or phone calls) can travel on. A channel bank helps make sure that each phone call stays on their own road and doesn't mix with other calls. This way, people can talk on the phone without hearing other people's conversations. It's like having your own private road just for your car!
