Supported Address Formats

The Cisco MGX and SES switch products support the following standard ATM formats:

•Native E.164

•Data Country Code (DCC)

•International Code Designator (ICD)

•AESA-embedded E.164

•Local AESA

The native E.164 address specifies an Integrated Services Digital Network (ISDN) number and is used by Public Switched Telephone Networks (PSTNs). A native E.164 address has a variable length of up to 15 Binary Coded Decimal (BCD) digits. The other address formats are usually used for private networks. The default address format for the Cisco MGX and SES switch products is the ICD format.

In the PNNI network, native E.164 addresses are mapped to an E.164 AESA format. The native AESA is inserted as a left-justified IDI portion of the AESA, with the semi-octet Hex FFFF padded to form an integral byte at the end. This left-justified rule may be changed to right-justified via CLI if needed.

The substructures of the address formats are transparent to PNNI routing. Figure 3-2shows the substructures of the supported ATM address formats. Table 3-1describes the substructures shown in Figure 3-2.
