Test Functions, continued
-
analog loop via the C/I command EAL: The analog S interface transmitter is internally
connected to the S interface receiver. When the receiver has synchronized itself to the internal
INFO 3 signal, the message "Test Indication" or "Awake Test Indication" is delivered to the
CIR register. No signal is transmitted over the S interface.
In this mode, the S interface awake detector is enabled. Therefore if a level (INFO 2/ INFO 4)
is detected on the S interface, this will be reported by the "Awake Test Indication (ATI)"
indication.
-
remote loopback via RLP bit in D_MODE register: The digital 2B data received from the S
interface receiver is loopbacked to the S interface transmitter. The D channel is not looped.
When RLP is enabled, layer 1 D channel is connected to HDLC port and DLP cannot be
enabled.
-
transmission of special test signals via layer 1 command:
* Send Single Pulses (SSP): To send isolated single pulses of alternating polarity, with pulse
width of one bit time, 250
μ
S apart, with a repetition frequency of 2 KHz.
* Send Continuous Pulses (SCP): To send continuous pulses of alternating polarity, with pulse
width of bit time. The repetition frequency is 96 KHz.
Figure 7.7 SSP and SCP test signals
7.3 Serial Interface Bus
The 192 kbps S/T interface signal consists of two B channels (64 kbps each), one D channel (16
kbps) and other control signals. The multiplexing/demultiplexing functions are carried out in the Serial
Interface Bus (SIB) block. In addition, the B1 and B2 channels can be individually set to carry 64 kbps
or 56 kbps traffic.
