MINI-LINK BAS 7-2
Technical Description EN/LZB 111 0542 P2B
7.1 Introduction
ATM is the transport technique used in MINI-LINK BAS.
ATM transport guarantees the efficient delivery of services with
totally different QoS requirements, such as data and telephony
services. This is obtained by deploying the flexibility of ATM virtual
connections and service categories.
The system exploits the fine bandwidth granularity and the statistical
multiplexing capability of ATM.
ATM transport along the system involves the following functionality:
•
Cross-connection of VCCs
•
Connection admission control for ensuring proper utilisation of
resources
•
Prioritisation of real-time traffic for low transfer delay and jitter
•
Extensive buffering of non real-time traffic
•
Fault management
