• loop at the analog end of the S interface;
• transmission of special test signals on the S/T interface according to the modified AMI
Data Sheet
code are initiated via a C/I command written in CIX0 register.
Test loop 3 is activated with the C/I channel command Activate Request Loop
(ARL). An S interface is not required since INFO3 is looped back internally to the
receiver. When the receiver has synchronized itself to this signal, the message "Test
Indication" (or "Awake Test Indication") is delivered in the C/I channel. No signal is
transmitted over the S interface.
In the test loop mode the S interface awake detector is enabled, i.e. if a level is
detected (e.g. Info 2/Info 4) this will be reported by the Resynchronization Indication
(RSY). The loop function is not effected by this condition and the internally
generated 192-kHz line clock does not depend on the signal received at the S
interface.
Two kinds of test signals may be sent by the ISAC-SX TE:
– single pulses and
– continuous pulses.
The single pulses are of alternating polarity, one S interface bit period wide, 0.25 ms
apart, with a repetition frequency of 2 kHz. Single pulses can be sent in all
applications. The corresponding C/I command in TE applications is TM1.
Continuous pulses are likewise of alternating polarity, one S-interface bit period
wide, but they are sent continuously. The repetition frequency is 96 kHz. Continuous
pulses may be transmitted in all applications. This test mode is entered in TE
applications with the C/I command TM2.
