In the above example, parameter 001 is displayed with a value of 00001. It can be seen
from table C1 that parameter 001 is the master / slave and number of lines setting, and that
value 00001 indicates that the modem is in Slave Mode with two transmission lines active.
Press “Loop Back” to step through the available values.
Press “Local Loop” to step to the next parameter.
Remember to press “Remote Loop” to store the parameter values and reboot the modem
once all parameters have been set to the desired values.
Table C1 provides a full list of the parameters and their values available for programming
using the front panel controls.
Note: You may not configure (via the front panel) an AM2048 MKII NTU's (Far end) User
Port parameters until AFTER the ELU has determined what type of user port the far end has.
The ELU will determine the user port of the far end automatically, as soon as one
transmission line has trained. I.e. Line 1 or Line 2 status LED is not red. All other
configuration parameters may be changed as required to get to this state.
Note: The front panel controls can only be used for configuration of point to point working
modes. Not all parameters that can be set via the VT100 screens can be set via the front
panel controls (e.g. idle pattern on G.703 interface). Anything previously set by the VT100
screens that cannot be accesed from the front panel controls will remain unchanged. Values
that are set via the front panel will override screen settings.
Note: Front Panel configuration should only be done (initially) after the unit has been cold
booted. This is because some configuration options which are settable via VT100 are
incompatible with the more limited range available on the front panel.
Note: The unit which is to be Master, should be set as such (via the front panel), and
rebooted into master mode before any other configuration is undertaken. This is because
certain configurations are not possible when in Slave mode. This matches the existing
enforced functionality of the unit.
