A unique identifier associated with voice communication services delivered over a fiber optic network by a specific provider. This identifier allows incoming calls to be routed to the appropriate endpoint and outgoing calls to be properly billed. For example, a residential customer might use this identifier to make and receive calls over their fiber internet connection.
This identifier offers several advantages, including enhanced voice clarity due to the digital nature of fiber optic transmission. Additionally, the reliability of communication can be improved as fiber networks are less susceptible to environmental interference compared to traditional copper wire systems. Historically, phone services relied on analog signals transmitted over copper infrastructure. The transition to fiber represents a significant upgrade in terms of bandwidth and overall communication quality.
