In “Inactive” mode, no data is accepted from the framer receive interface.
In “Active” mode, data is accepted from the framer receive interface, segmented and
cells are written into the Segmentation Buffers and the Output Queue.
In “Standby” mode, data is accepted from the framer receive interface but no cells are
written in the Segmentation Buffers.
In “Substitute” mode, data is accepted from the framer receive interface, but substituted
by a programmable byte-pattern selected by “subst_bpslct” in the “AAL Receive
Reference Slot”. Cells are written into the Segmentation Buffers and the Output Queue.
This mode can be used for trunc conditioning to indicate idle (bit pattern = 0x7F) or out-
of-service conditions (bit pattern = 0x1A) according to af-vtoa-0078 [10] and TR-NWT-
000170 [14]
When activating the AAL segmentation channels, it is important to follow the initialization
sequence as shown in
the AAL channel. During this time the device connected to the Framer Receive Interface
has to be in normal operation allowing the IWE8 to synchronize itself on the frame pulse.
