SEND CONTINUOUS DATA UTILITY

The Send Continuous Data utility is used to test the integrity of the link, to send a continuous selectable bit pattern across the link and to optionally check any received data that is wrapped back. Points from which data can be wrapped back are:

• local modem cable wrap switch

• Local modem (if it supports a local wrap)

• remote modem (if it supports a remote wrap and a duplex facility is being used)

• remote Displaywriter (if a duplex facility is being used).

When a wrap is not possible, the receiving station can monitor the pat-tern sent from the Displaywriter for errors.

To choose this utility select Send

from the BSC LINK ANALYSIS menu. The SEND CONTINUOUS DATA SETUP menu will appear.
