What is the fundamental difference between the T-PE and the T-LL?
The difference between the Phone Line Extender (PE) and the Leased Line Emulator (LL) is that the LL provides a continuous radio link and is configured for 2 or 4 wire audio only circuits. The Phone Line Extender (PE) is used to emulate a telephone link and includes loop signaling and ring circuitry. The PELL has one phone line and one leased line circuit.
