    DTE data rate, etc. Data Mode The DataComm V.34 PL modem is in data mode while it has a telephone line connection to another modem or is in the process of establishing a connection. In Data Mode the modem transmits all the data it receives from the DTE over the phone line.

  • Page 32: Clock Selection

    The synchronous format relies on transmit and receive clocks to maintain character timing. It therefore does not need start and stop bits for each character as does the asynchronous format. The DataComm V.34 PL modem can be configured to use one of the following three clock sources to transmit synchronous data: •...

  • Page 33: Testing The Modem

    When that is the case the connection usually will not be dependable and will be filled with errors. To correct such situations, the transmit level of the DataComm V.34 PL for private line operation can be configured in 1 dBm increments between 0 dBm and -15 dBm. This selection can be done from the front panel by entering tL then 0 to 15.
