FCC Registered DAA Module with DTMF Transmitter/Decoder
Description The XE0068DT is an FCC registered telephone line interface which includes a DTMF transmitter, DTMF decoder and call progress monitor. FCC rules limit the signal level that equipment can place on the telephone line. The XE0068DT incorporates an Automatic Gain Control (AGC) circuit to control the output signal level. The AGC optomizes the output levele over a wide variety of input levels without introducing signal distortion. FCC rules also dictate a 2-second delay at the start of each call. This billing delay prevents information transmission during the billing period. The XE0068DT includes this billing delay. The integrated DTMF transceiver, call progress monitor and FCC registration make the XE0068DT ideal for network signalling applications. Features * * * * * * * * * * Small Size - 2.28" x 1.08" x 0.42" User Transferrable FCC Part 68 Registration Integrated Ring Detection Circuit. Solid-State Hookswitch Control Provides 1500 Volt Isolation between the telephone line and all other circuits Includes supplemental surge protection to survive both FCC Type A and Type B surges. Integral 2-Second Billing Delay (required for FCC Part 68 registration) Automatic Gain Control optimizes transmit level for most any input level. Integral DTMF transmitter and decoder Call Progress Monitoring
