E.164 — For E.164 AESA addresses, the IDI field contains an eight-byte E.164
address. This E.164 address uses the international format and consists of up to fifteen
decimal digits. E.164 Anycast AESA provides a group address function for this
address type.
Embedded E.164 AESA format — An embedded E.164 is a specific type of AESA
format that requires a specific encoding in the IDI section. As shown in the
example below, a Native E.164 address is converted to BCD format. Leading
zeros are added to obtain the maximum length of 15 octets and a trailing
semi-octet 0xF is added to pad the final semi-octet. The high-order domain
specific part (HO-DSP) and the end system identifier (ESI) must be all zeros. For
specific information, see Section 5.1.3.1.1.3 of the ATM User-Network Interface
(UNI) Specification 3.1.
