This menu displays the type of DTE interface currently fitted in the BBM. The BBM automatically “reads”
which interface type is fitted on power up and programs certain options accordingly. The first two display
options are read only. These display the following information:
9.1 9.1 Operation Operation
Scroll up and down through the items with the ñ and ò keys. Set the item to the required value using
the SELECT key. Program the entire set of configuration options by using the PROGRAM key.
A star appears by any item that has been changed but not programmed. The yellow program LED should
be lit when there are any items in the menu that have been changed but not programmed.
The BBM will detect one of the following interface types:
The next items are control line options which can be applied to the X21bis, V.35, V.36 interface:
SS
This line allows the circuit 105 line to be clamped on permanently if required. Note : X.21 modules have a
single option to force C Normal or C set On.
SS
This line allows the circuit 106 to follow circuit 105 after a delay of about 10 to 20ms.
S S For X.21 bis
For V.35, V.36
This line allows the circuit 107 line to follow 108 if required.
SS
This line allows the circuit 108 line to be clamped on permanently if required.
There is no control line 108 directly associated with V.35 / V.36, so it is held ON internally. This means that
although it is not displayed, the option 108 set on is active with V.35 or V.36 interfaces fitted.
The Option and Config Menus have a bottom item `Program Items’ which is only visible if any settings have
been changed (PROG LED is on). This item is removed when the user goes to this item and presses SELECT
button or presses the PROG button. Both actions save the new settings into the Flash memory and the
PROG LED will go off. Note: If the user leaves the menu without programming the items or does not press
any buttons then the display reverts back to the Status Menu and any changes made will be discarded.
10. 10. Configuration Menu Configuration Menu
This menu contains the items that are used in the initial configuration of the BBM. Once set up, they are
usually left unchanged for normal BBM operation. All of the configuration parameters are stored in non-
volatile memory and are restored each time the BBM is powered up.
