How does a trunk differ from a telephone line? please explain

Solution

A trunk does not have a telephone number associated with it because it carries hundreds of voice and data channels.

Trunk dialing is a telephone system allowing subscribers to dial trunk calls without operator assistance.

A telephone number is a sequence of digits assigned to a fixed-line telephone subscriber station connected to a telephone line or to a wireless electronic telephony device.
