Channel [0—3] ATM Scrambler Framer
State.
Reserved. These bits must be written to their
reset default value (0x000).
ATM Framer Sync State. These bits indicate
the X31 sync state of each channel.
ATM_ST_[0—3][3:2] = 00 Acquisition
ATM_ST_[0—3][3:2] = 01 Verification
ATM_ST_[0—3][3:2] = 10 Synchronized
ATM_ST_[0—3][3:2] = 11 Undefined
ATM Frame State. These bits indicate the
frame state of each channel.
ATM_ST_[0—3][1:0] = 00 Hunt
ATM_ST_[0—3][1:0] = 01 Presync
ATM_ST_[0—3][1:0] = 10 Sync
ATM_ST_[0—3][1:0] = 11 Undefined
ATM X43 Frame Control.
Reserved. These bits must be written to their
reset default value (0x0).
X43-Alpha. This register will define the alpha
value for the X43 alpha-delta framer which is
the number of consecutive incorrect ATM cells
that must be received in order to transition from
the sync state to the hunt state.
X43-Delta. This register will define the delta
value for the X43 alpha-delta framer which is
the number of consecutive correct ATM cells
that must be received in order to transition from
the presync state to the sync state.
