The channel mapping can be dynamically reconfigured without disturbing other active
channels of the same port.
Note: If frame based SDT without CAS is used and filling level ≤ 45, the condition
band_width ≤ part_fill has to be fulfilled for correct operation.
Multiframe based SDT without CAS should not be used.
4.11.2.3 Structured CES with CAS
If a port is used for structured CES with CAS, additional signalling is inserted into the
channel overhead. The associated RAM slots, 0 in T1 mode and RAM slots 0 and 16 in
E1 mode, need to be configured as reference slots with “sdt_mfs” = 1.
Please note, that all settings of the AAL Reference Slot refer to the channel payload.
Therefore, in case of T1 mode in FAM or E1 mode the channel has to be set to inactive
(“channel_mode” = 0) with no bandwidth assigned (“band_width” = 0).
