Data Adaptors operating in stand-alone mode are treated as
PDMODULE Maintenance Objects.
Figure 28. Digital Line Connections
Only 2-wire Italtel Digital Telephone Models 1 and 2 (IDT1/2) or DAs can be
directly connected to a TN2136. DCP (4-wire) digital voice terminals and data
modules can be connected to these circuit packs via Italtel's 2/4-wire adapter.
DAs can operate in either of two modes which are covered by different
maintenance objects:
DA Mode
Stand-alone
Linked
Digital Line maintenance interacts with Digital Line circuit pack (DIG-BD)
maintenance, and results of DIG-LINE testing can be affected by the health of the
Digital Line circuit pack. Keep this in mind when investigating reported Digital Line
problems.
