Problems Related to External Speakerphones
The following problems may occur with some external speakerphones connected to the 200-type module. These problems may occur with other equipment as well.
PROBLEM: YOU CANNOT MAKE/ANSWER CALLS AT YOUR 2420 TELEPHONE
The analog equipment attached to your 2420 telephone may be off-hook because it does not detect the “disconnect” signal sent from the 200-type module. You must manually turn off (that is, place on-hook) your analog equipment.
PROBLEM: ANALOG EQUIPMENT DOES NOT GO ON-HOOK WHEN YOU LIFT TELEPHONE HANDSET
The analog equipment attached to your 2420 telephone may not go on-hook automatically when you lift the 2420 telephone handset for two reasons. First, make sure that the switch settings on the 200-type module are correct. Remove power and refer to the 20-Type Stand, 200-Type Module Analog (U.S.) Adjunct Interface, and 201-Type Module Recorder Interface Installation and Safety Instructions (555-233-132). If the settings are correct, the analog equipment does not detect the “disconnect” signal sent from the 200-type module. You must manually turn off (that is, place on-hook) your analog equipment.
PROBLEM: ANALOG EQUIPMENT DOES NOT GO ON-HOOK WHEN THE FAR END DISCONNECTS
The analog equipment attached to your 2420 telephone may not go on-hook automatically when the far end of a call disconnects because the equipment does not detect the “disconnect” signal sent from the 200-type module. You must manually turn off (that is, place on-hook) your analog equipment.
