Abstract

The telephone network and the internet use different address spaces. The telephone network uses ATM-addresses, the internet uses IP-addresses. So far it is not possible to reach an ATM-end user system (e.g. telephone) from the internet. Here is proposed to include the IP-address range into the ATM-address range, namely the E.164 AESA (ATM End System Address), in order to enable that ATM-end user systems are reachable from the internet. The E.164 AESA format uses 20 octets (Fig. 1). An octet represents one byte in hexadecimal notation. The IDI (Internal Domain Identifier) uses 8 octets to address the domain, i.e. the country code and numbers. The ESI (End System Identifier) uses 6 octets in the DSP (Domain Specific Part) to address the end user system. An E.164 AESA address, which has the DSP set to all zeros, is called an E.164e (Embedded E.164 AESA) address. The current IP Version 4 (IPv4), as defined in RFC791, includes 32 bits, broken down into four 1-byte segments that uniquely identify a specific host on a specific network in the internet. In the decimal notation these 1-byte segments range from 0 to 255, therefore each of the four segments of an IP-address uses three decimal digits, e.g. www.xxx.yyy.zzz.

The telephone network and the internet use different address spaces. The telephone network uses ATM-addresses, the internet uses IP-addresses. So far it is not possible to reach an ATM-end user system (e.g. telephone) from the internet.

The E.164 AESA format uses 20 octets (Fig. 1). An octet represents one byte in hexadecimal notation.
