Programming for ISDN Line Identities
Most of the programming for ISDN line identities must be done at node A.
At node B, only the ISDN access code, "9", needs to be programmed. At
node A, a digit conversion table is required to reverse the Incoming Digit
Conversion performed on DDI calls on the DASS2 route. This conversion
will provide the ISDN with consistent line identities. Refer to
"Application of a Line Identity conversion table" (page
Table 11
Application of a Line Identity conversion table
Internal Digits
Note that if a non-DDI extension on either node makes an outgoing call
to the ISDN, no line identity will be supplied by the private network. The
ISDN must provide a default line identity.
