Final answer:
In ATM, for any data packet traversing through cells, the minimum and maximum values of the L field in the CS field are 0 and 1 respectively. This is independent of the number of cells passed.
Step-by-step explanation:
In the context of Asynchronous Transfer Mode (ATM), the L field in the Convergence Sublayer (CS) field is used to indicate the payload type that the ATM cell is carrying. The ATM cell has a fixed-size of 53 bytes, with 5 bytes for the header and 48 bytes for the payload. In a CS field, the L field can either be 0 or 1, where 0 indicates that the cell contains user data and 1 indicates that the cell is the last one in a series. If a data packet is sent through 50 cells in ATM, the L field can change for each cell. The minimum value for any ATM cell's L field is 0, and the maximum value is 1, regardless of the number of cells the data packet traverses.
