Supported Address Formats

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