3-5 MINI-LINK BAS
EN/LZB 111 0542 P2B Technical Description
In fact, the C-AAS has here to terminated the CBR (typically E1/T1)
traffic. The ET link capacity and the number of CE boards, in terms of
E1/T1 ports, constitute the bottleneck of such a configuration.
Moreover, it must be noted that the intermediate configurations are
possible. In fact, as the CE boards can be hosted both into the R-AAS
and into the C-AAS, additional PSTN links could be obtained using
available slots in the R-AAS directly.
This configuration is well suited when the physical connection points
with the PSTN are co-located with the C-AAS, while the R-AAS is
remote.
The C-AAS is basically equipped with CE boards and one ET board
connected to the ATM backbone, in slot 1.
