Services and Transmission Are Different
Network
Service: Something a customer wants
(Capacity, interface, service level)
Transmission: Moving bits inside the network
at the right cost and quality
For example: 10GbE LAN PHY

For example: 10Gb/s NRZ wave
(with various optical specs)
Note: for optical, services and transmission have been conflated in the past.
