Basic ILMI Functions 325
UNI Address
Registration The ILMI address registration provides the following services:
Initialization-time exchange of addressing information
Restrictions on network-prefix/user-part combinations
Acceptance of unassigned network prefixes
Rejection of unacceptable values, either rejection of a specific network
prefix by the user, or of a specific user part by the network
Dynamic addition and deletion of additional network prefixes and user
parts
De-registration of addresses when ILMI Connectivity is lost
An indication of support or non-support for address registration at an
interface
Registration of organizational scope
Exchange of Addressing Information
To establish an ATM connection at the UNI, both the user and the
network must know the ATM addresses of the ATM devices that
participate in that UNI. These ATM addresses can then be used in
signaling messages for establishing connections with a specific ATM end
system. The address registration procedure allows the dynamic exchange
of addressing information between the user and the network at the UNI,
at initialization and at other times, as required.
Address registration is done in two phases. The network side IME supplies
the network prefix of the address, and the user side IME appends the user
part to it and registers the complete address with the network side. Either
side can dynamically register and de-register its respective parts of the
address. This registration process provides the network with the
information needed to automatically route a call to its destination
address.
The user-side device automatically registers its organizational scope
variable with the network side to assure that the network is aware of the
users who attached to it (see next section).
