ASMi-31 Ver. 3.0 Configuring Line Parameters 4-3
If you selected the clock type to be EXT RCV, the bit rate of both the local
and remote modems will be set to AUTO and this state will be displayed in
the Parameters field of the DTE CONFIG, DATARATE menu.
At the same time the modem measures the frequency of the external clock. If
the rate is one of those supported by the device, it is displayed in the
Parameters field of the DTE STATUS, DATARATE menu. If the clock rate is not
supported by the device, or no clock is provided, the Parameters field of the
DTE STATUS, DATARATE menu displays AUTO and the ILLEGAL EXT CLK alarm is
stored in the alarm buffer.
If the management is active, the external clock report is sent to the remote
unit and also displays the same parameters as the local unit. If the
management is not active, the remote unit displays the available clock rates
and the operator will have to select the rate manually.
