Appendix C. ATM Address Formats
The 8265 ATM subsystem supports the addressing scheme defined by the ATM Forum for addressing
end-points in private ATM networks. The scheme is modeled after the format of the OSI Network Service
Access Point (NSAP) as specified in ISO-8348 (CCITT X.213).
As shown in Figure 12, the ATM Control Point supports the three initial domain identifier (IDI) formats
specified by the ATM Forum:
DCC (Data Country Code)
E.164 (Specific Integrated Service Digital Network Number).
ICD (International Code Designator)
Each of the three ATM address formats is 20 bytes long and consists of two main parts:
Network Prefix (13 bytes)
End System Part (7 bytes).
