DSP Missing from DACS Information

If there is a DSP card (either TDM or Waveform Synthesizer) in a DACS system that isn’t show-

ing up on the “DACS Information” page after you click “Find DSPs”, there are a few things you’ll

need to check.

1. Verify that the DACS options ﬁle supports multiple DSPs. To do this, click on the “DACS

Info” option in the DACS Menu (blue blocks in frame). In the “Software Information”

table, look for the line “Max. # DSPs Supported”. If this line appears to be incorrect, you

will need a new options ﬁle for the DACS system. Contact ASTi with the system’s serial

number for more information.

2. Verify that the DACS conﬁguration ﬁle on the system speciﬁes the correct number of DSP

cards. To do this, click on the “Conﬁg.” menu option in the DACS Menu. In the “Current

Conﬁguration File” table, click the “View” icon next to the “Loaded File” line. There

should be a line in the ﬁle (which appears in a new browser window) like this:

number_dsps=X

...where “X” is 1, 2, or 3. If there is no such line in the conﬁguration ﬁle, or the line is

incorrect, you will have to add/edit the line from the DACS system directly.

3. Verify that all the DSPs that you’re supposed to have are correctly seated and installed in

the DACS chassis, and are functioning properly.

DSP Not Responding

The presence of a DSP icon with a red “X” indicates that RMS cannot get information about a

certain DSP, because it is not responding.

1. Verify that the currently-loaded DACS conﬁguration ﬁle reﬂects the correct number of

DSPs in the system (click on the “Conﬁg.” menu option, then click on the “View” link of

the conﬁguration ﬁle indicated as -> Loaded <-).

For example, if there is a line in the conﬁguration ﬁle “number_dsps=2” when the DACS

system has only one (1) hardware DSP card, RMS will return the red “X” alert message.

2. If the “number_dsps” line in the DACS conﬁg. ﬁle is correct, however, the missing DSP

could be incorrectly conﬁgured, or it could be malfunctioning.

RIU Not Responding

The presence of an RIU icon with a red “X” indicates that the RIU listed in the Telestra RMS con-

ﬁguration ﬁle did not appear to be connected to the speciﬁed DSP card.

1. Verify that the RIU is connected to the TDM ring properly.

2. Verify that the RIU is synchronized with the TDM ring. The green LED on synchronized

RIUs will blink at a slower rate (~1 Hz) than on unsynchronized RIUs (~5Hz). If the RIU

is not synchronized, make sure that the running model includes an RIU Input object corre-

sponding to that RIU’s address.

3. Verify that the RIU is assigned to the proper DSP card in the RMS conﬁguration ﬁle.

4. Verify that the RIU Address in the RMS conﬁguration ﬁle matches the physical hardware

address set on the RIU itself.
