When an Off-Premises telephone is connected to the LEGEND system via the 008 OPT module certain accessories must be used for grounding and protecting the system from power surges, electromagnetic interferences, and electrostatic discharges. These components are specified in Section 5 of the LEGEND System Reference Manual.
Service technicians should be aware that the 008-OPT module is the same as the 008-DID module except that the battery strap is in the On position for OPS, and in the Off position for DID. The factory presets the strap and labels the module accordingly, based on the DOSS order.
The OPT trunk from the CO provides -48VDC on the tip/ring interface to the OPT station.
The MERLIN Off-premises Telephone lnterface (OPTI) (PEC 2302-OPI) cannot be used with the LEGEND system.
