Data Diagnostics
Data diagnostics support varies among data cards. Generally, data card diagnostics supported
include the setting of various levels of loopbacks toward the network or the attached DTE
equipment. Other support includes the ability to generate and respond to industry-standard
loop-up and loop-down codes that are compatible with DDS, V.54 and/or Fractional T1 (FT1)
formats. The DS0-DP data card generates and detects DS0-DP loopback codes. The table
below shows detailed information on the diagnostic capabilities of the Data cards.
