The TelTap is a versatile and inexpensive telephone coupler. Once connected to a standard RJ-11 plug, the user has a choice of seizing the phone line or just tapping the line. The TelTap can be used to either send or receive audio regardless of which mode is selected. Internal jumpers let you choose how the TelTap operates. You can set the second phone port to automatically disconnect whenever the TelTap is in the line seize mode. You can also choose to never tap the line, only seize the line. A ring LED indicates the presence of an incoming call when there is no audible ringer making the TelTap a good choice for both studio and field work. A mute switch disconnects the audio port when silence is required.
