The L2 comprises of Medium Access (MAC) and Radio Link Control (RLC).
The MAC provides unacknowledged transfer of SDUs between peer MAC
entities, and the RLC provides data transfer of SDU and can also support the
retransmission protocol. L3 comprise the Radio Resource Control (RRC),
which interfaces with L2.
7.3 Mub Interface
The Mub is the management interface for the RBS and, in contrast to the Iub, is
not standardized. The user interacts with the system using a web based thin
client. The thin client gets software that is dependent on the managed RBS by
loading Java applets from the RBS at execution time.
The Mub is based on IP, so the RBS has an IP address. Remote management
uses IP over ATM and on-site management uses Ethernet. The necessary
low-level communication layers, including FTP server, HTTP server, ORB and
Telnet server, are provided by the common platform.
The management interfaces are shown in figure 6.

The interfaces are used as follows:
• Telnet
Telnet provides local and remote access to the operating system shell.
The command line interface provides a set of commands handled by a
Unix shell-like command interpreter.
