PRBS Testing
If the control bit ADSEQ is zero (from master control page 1 - access control word), any channel or combination
of transmit channels may be programmed to contain a generated pseudo random bit sequence (2
15
-1). The
channels are selected by setting bit three (TTST), in the per time slot control word.
If the control bit ADSEQ is zero, any combination of receive channels may be connected to the PRBS decoder
(2
15
-1). Each error in the incoming sequence causes the PRBS error counter to increment. The receive
channels are selected by setting bit 2 (RRST) in the per time slot control word.
If PRBS is performed during a metallic or external looparound, per time slot control words with TTST set should
have RRST set as well.
15.5
Digital Milliwatt
If the control bit ADSEQ is one, a digital milliwatt sequence (Table 18) in T1 mode or (Table 19) in E1 mode
may be transmit on any combination of selected channels. The channels are selected by setting bit three
(TTST), in the Per Time Slot Control Word.
Under the same control condition (ADSEQ equal to one), the same digital milliwatt sequence is available to
replace received data on any combination of DSTo channels. This is accomplished by setting bit two (RRST) in
the Per Time Slot Control Word for the corresponding channel
.
Table 19 - A-Law Digital Milliwatt Pattern (E1)
15.6
Per Channel Inversion
When bit six (PCI) in the Per Time Slot Control Word is set both transmit and receive data for the selected
channel is inverted before going onto the line / DSTo respectively.
