Description
Figure 1 shows the architecture of an ATM switch
designed with the ATLANTA chip set. The LUC4AU01
ATM UNI Layer Manager (ALM) chip performs the ATM
layer network interface (UNI or NNI) management func-
tions for an MPHY line card and can be programmed to
work with proprietary ATM switch fabric cores.
The ALM operates in a full-duplex manner, with a max-
imum ATM cell traffic rate of 662 Mbits/s in each direc-
tion. The ingress side processes cells arriving from the
UNI; the egress side processes cells being sent to the
UNI.
