Applications
Telephone cables are primarily used in the local loop, forming the physical backbone that connects individual homes and businesses to the telephone exchange, enabling basic landline voice service.
Call center operations: Support for dozens of agents with a high-capacity digital circuit (such as a PRI link or multiple SIP channels) instead of dozens of physical analog lines.
Modern multi-line business phone: A small business using a single SIP link through its internet connection to provide 5, 10, or 20 external lines to its staff.
Cellular macrobase return link: Connection of a cellular antenna to the backbone network via a high-capacity multiplexed link (e.g., fiber with TDM) that carries thousands of simultaneous calls and data sessions.
