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.
