Appendix E. ONcore ATM
Address Formats
The ONcore 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 E-1 on page E-2, the 6416SW 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).
