Final Answer:
In a bonded service setup, although multiple pairs of cables are combined to amplify bandwidth, the dial tone typically operates solely on one pair.Therefore the given statement is "There dial tone on both pairs of a bonded service . is False.
Step-by-step explanation
Bonded service utilizes multiple pairs to increase bandwidth, but the dial tone typically exists on only one pair of the bonded service.
In bonded services, multiple pairs of copper cables are combined to enhance data transmission capabilities. However, the dial tone is generally present on just one of these pairs. When a bonded service is established, the dial tone is assigned to a single pair for communication purposes.
The other pairs are used to augment bandwidth, enabling higher data rates by aggregating the capacity of multiple lines. Therefore, while there might be dial tone functionality on one pair, the others are primarily utilized for data transmission, not for generating dial tones.
