"The CyberData SIP Paging Adapter’s 600 Ohm Page Port output connects to a TOA 900 series amplifier with a TOA L-41S plug-in module. The TOA L-41S plug-in module is a separate component used for Page Port inputs with mute control. Please contact TOA Technical Services & Product Support for questions about TOA products."
