Morphology
The compound is partly compositional: a B1 learner who knows 'subscriber' (a person who subscribes) and 'line' (a communication channel) can infer it refers to a communication line for a subscriber. However, the specific telecommunications sense (the technical link to the local exchange) is domain-specific and not fully predictable from the constituents alone, so it is only partially transparent to learners.
Etymology
Subscriber line comes from early telephone days: the word subscriber meant the paying 'customer' and line meant the physical wire running from their home to the local phone office, so the phrase now means the actual phone connection that links a customer's home or building to the phone company.
