system set clockmode <internalexternalreceiverecover>: Sets the clock mode. Internal clock mode means the 3088 provides the clock to both the DSL and the serial interface. External clock mode means the 3088 uses the serial transmit clock as its DSL transmit clock (V.35 only). Receive recover clock mode means that the 3088 uses the DSL receive clock as its DSL transmit clock and as the serial receive clock.

Note X.21 External Clock Mode—The X.21 interface expects the DCE to provide the clock used for both transmitting data and for sampling receive data. When the 3088/D is set as a DCE, it may be used in internal or receive recover clock modes. The DSL generates a clock that is provided to the X.21 interface.

When the 3088/D is a DTE, it may be used in external clock mode. The X.21 interface needs to provide the clock. This clock is used by the DSL to sample the serial data and also to update the receive data.

The 3088 is set for either DCE or DTE by flipping the daughter- card. The 3088 is a DCE if DCE points away from the serial interface toward the front of the 3088. Note that this is different than the 3086/D.

The following commands allow the user to view the current system configuration:

system show circuitid: Shows the circuit ID.

system show timeslots: Shows the number of timeslots. The data rate can be calculated by 64K x timeslots.

system show clockmode: Shows the clock mode.

Any changes to the system configuration or the DSL configuration will be lost on the next power cycle unless the changes are saved. The com- mand system save config is used to save the changes.

System Status Commands

The following commands show system status:

system show status: Shows the following system status information: LEDs, DSL test mode, front panel switch settings, DSL link state, and configuration mode.

system show configmode : Shows the configuration mode. If the DIP switches are set to all on, then the configuration mode is DIP switch. Otherwise, the configuration mode is software. In DIP switch configu- ration mode, the system configuration cannot be changed through either the console or EOC.
