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).
