Telephony Training System (8086)
The Lab-Volt Telephony Training System (TTS), Model 8086, is a powerful learning tool that provides training on modern telephone networks and digital private automatic branch exchanges (PABX).
It is also an essential tool to introduce students to the Integrated Services Digital Network (ISDN). The TTS is built upon state-of-the-art, programmable equipment that operates real world devices, including telephone sets and trunk lines.
The TTS courseware covers the following fields of telephony: analog access to the telephone network, central office operation, digital PABX, PABX analog trunk, and digital trunk.
Furthermore, while performing the courseware material for the digital PABX or the digital trunk, students are introduced to the following two major aspects of ISDN: the physical layer (layer 1) and the network layer (layer 3).
