For either unit, the message on the bottom line can be any one of the following:
Displayed Message Expanded Meaning
OK-ReBalance Done
Full re-balance was achieved
OK(P)CnCRatio

Lim
Partial re-balance, limited by CnC ratio approaching its working limit
OK(P)-LocalPwr

Min
Partial re-balance, limited by local power approaching its lower limit
OK(P)-LocalPwrMax
Partial re-balance, limited by local power approaching its upper limit
OK(P)-LocalPwrLim
Partial re-balance, limited by local power approaching TPLI
max
OK(P)-DistPwrMin
Partial re-balance, limited by distant power approaching its lower limit
OK(P)-DistPwrMax
Partial re-balance, limited by distant power approaching its upper limit
OK(P)-DistPwr

Lim
Partial re-balance, limited by local power approaching TPLI
max
OK(P)-Incomplete
Partial re-balance, algorithm did not fully converge
No APC Frame Sync
Communication not possible – no APC frame sync
Locl EbNo too high
The local Eb/No is too high (>16 dB) to determine re-balance params
Dist EbNo too high
The distant Eb/No is too high (>16 dB) to determine re-balance params
DistEnd ReBal fail
The distant end failed to re-balance
DistEnd NoResponse
The distant end failed to respond
Fail-CalcMismatch
No Re-balance - the solution calculated by each end does not match
CnC Ratio too high
The CnC ratio is too high (>9 dB) for re-balancing to be attempted
LoclMargin too low
There is insufficient local Eb/No margin for an APC re-balance
DistMargin too low
There is insufficient local Eb/No margin for an APC re-balance
Rx DataRate<64kbps
The Rx data rate needs to be 64 kbps or higher for APC
Rx DataRate<64kbps
The Tx data rate needs to be 64 kbps or higher for APC
Local RSL too low
The local RSL is below the minimum for the operating symbol rate
Dist RSL too low
The distant RSL is below the minimum for the operating symbol rate
