RAM
However, it is possible to define other ATM cell mappings, e.g. ATM cells in less than 32
64 kbit/s channels. However, RAM slot 1 has always to be defined as Reference Slot.
4.11.2
4.11.2.1 Unstructured CES
For unstructured CES according to ATM-Forums CES Specification [10] there is only
one channel per port. Therefore, the internal configuration RAMs 1 to 3 have only to be
