The AIUD/AIUQ supports ATM switching and ATM protection.
The AIUD supports two external ports and two internal ports.
The AIUQ supports four external ports and four internal ports.
The AIUD/AIUQ accesses a maximum of 155 Mbit/s ATM services.
The ATM service is accessed by the optical fiber and is in the SDH frame structure. The payload is the ATM service.
The AIUD/AIUQ multiplexes and maps the ATM service, loads the ATM service into SDH VC-4s, and finally sends the SDH VC-4 signals to the SDH network.
Table 1 provides the functions and features of the AIUD/AIUQ.
