FID RULES/CONSTRAINTS:
  1. For mechanized flow-through, FID may be entered on the FEATURE USOC logical line of CLS or one of the following combinations of FIDs appear on the same logical line:
      -Primary Number (PN) and Call Appearance (CAPP) (with the CA attribute)
      -PN and Key Designation (KEY)
      -Telephone Number (TN) and Service Profile Identifier (SPID)
      -Telephone Line Identifier (TLI), PN and Terminal Number-Multiline Group (TER)
  2. When PS equals DY, the Terminal (TRML) FID must appear on the same logical line.
  3. DMS-100 (NA008) (NI2)
    The Integrated ISDN Terminal (INTT) FID is required when the LTCL FID, Elements 3 and 4, have the value of "NI2" and "D" respectively, i.e., CS = NI2 and PS = D.
  4. T, F, and X order types prohibited for Access Service application.
  5. X action code prohibited on Access Service orders.

NI2Terminal supports NI2 features and functional capabilities as indicated in the element rule (DMS-100 NA008)

Element Rules:
Code set value of NI2 indicates the ability to support more than two B-Channel terminals on a BRI, and the ability to support Directory Number (DN)  sharing over multiple call types on an Integrated ISDN terminal.
When element 3 is NI2 and element 4 is D, the FID INTT is required.
The absence of data entry infers YES.
