Manufacturer:TI Description:The interface should be arranged to allow simple data transmission from the terminating central office, to the CPE (Customer Premises Equipment), only when the CPE is in an on-hook state. The data will be transmitted in the silent period between the first and second power ring before a voice path is established. The transmission level from the terminating C.O. will be -13.5dBm+/-1.0. The worst case attenuation through the loop is expected to be -20dB. The receiver therefore, should have a sen- sitivity of approximately -34.5dBm to handle the worst case installations. The ITU-T V.23 is also using the FSK signaling scheme to transmit data in the general switched telephone network. For mode 2 of the V.23, the modulation rate and characteristic frequencies are listed below: |
