TC12 Installation, Commissioning & Maintenance Handbook 
If ONLY any of the following faults are recorded when in Outstation or Monitor 
mode, Whilst OTUs respond with out faults to test set in Instation mode: 
 
BIC, CMS If Instation not transmitting sufficient bytes and OTU is last on the 
line 
RCRC If OTU replying with too many of to few control bytes 
 
POSSIBLE FAULT: 
Due to Control data errors e.g. incorrect numbers for 
OTU or incorrect numbers of OTUs on the line.
 
 
If ANY of the following Recorded whilst in Outstation Or Monitor mode. 
 
On test set, CFE, CCRC, BIC, SCM, SL, Not Yet Synchronised. 
 
POSSIBLE FAULT: 
Data corruption due to incorrect baud rate at in station 
or faulty modem board. 
 
 
WHILST CHECKING AT OUTSTATION: 
 
If ONLY any of the following faults are recorded when in Instation or Monitor 
mode, Whilst UTC TCC/Instation operates with out OTU faults when test set is 
used to simulate the OTU, i.e. in Outstation mode: 
 
On test set, Reply Idle and/or CD indicator not showing carrier being 
detected
 
POSSIBLE FAULT: 
Outstation not transmitting, to confirm simulate OTU 
with test set, i.e. switch ITS to Outstation and check that 
UTC TCC/Instation is communicating with it. If the ITS is 
replying and Instation is not recording OTU faults. 
Check OTU fault log to determine reason for OTUs 
failure to reply. 
 
If ONLY any of the following Recorded whilst in Outstation Or Monitor modes, 
Whilst OTU responds with out faults to test set in Instation mode. 
 
On test set CFE, CCRC, Not Yet Synchronised, BIC, SL
CNL1 Inter message gap between last reply message and start of next 
control message being infringed upon, check OTU replies especially 
OTU at last address. 
 
POSSIBLE FAULT:  
Data corruption due to line or Instation. If already tested 
at Instation and no fault indicated by test set when this 
OTU is simulated with test set in Outstation mode, this 
would now indicate Line or Interference from another 
OTU on the line. 
 
If ONLY any of the following Recorded whilst in Outstation Or Monitor modes, 
Whilst OTU responds with out faults to test set in Instation mode.
