In the event the CPE does not have a jack, but instead has a cord, plug the cord into the Model 240s jack and transmit tone! Features: Insulated inductive probe tip prevents shorting conductors Tests include wire trace, continuity test, clear/busy/ringing line test and. This allows the CPE circuit to be viewed in both directions, towards the Central Office and towards the customer premise. Includes Alligator clips, RJ45 and RJ11 modular. The set can be connected to the Network Interface Device (NID) with either the two individual clips or the modular cord. Featuring a wire trace, continuity test, clear/busy/ringing line test, and tip/ring identification. The AINES 240 HAL Tone Generator is a water resistant tone generator equipped with a weathertite 2 conductor modular cord and jack.
