NTERFACE ANAGEMENT
This section discusses the following ILMI services provided by IME:


Status Information

UNI Address Registration

Access to Service Registry MIB


ILMI Connectivity Polling
The IME extracts the following status information from the ATM interface
MIB for display:


State of the physical link connecting to adjacent IMEs


ATM layer configuration information, including the size of VPI and VCI
address fields in the ATM cell header, the number of configured VPCs
and VCCs, and the maximum number of VPCs and VCCs allowed


Parameters that are used for auto-discovery. For example, device type
and NNI signaling version.
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/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
