DTTA device driver

The device driver for the DTTA is included with Blueworx Voice Response. Before installing the DTTA adapters, you should ensure that Blueworx Voice Response is installed.

After installing Blueworx Voice Response, and the DTTA device drivers, you need to run a machine power cycle, reboot, or run the cfgmgr command to configure the adapters.

To check that the DTTA is installed, type the following command:
lsdev -C | grep rpq
This will display a list of the installed adapters and associated device drivers. Here is an example of what you would see if four adapters were installed:
rpqio0    Available 1H-08     Quad Digital Trunk Telephony PCI Adapter
rpqio1    Available 1V-08     Quad Digital Trunk Telephony PCI Adapter
rpqio2    Available 1Z-08     Quad Digital Trunk Telephony PCI Adapter
rpqio3    Available 1D-08     Quad Digital Trunk Telephony PCI Adapter
ddrpqio0  Available 1H-08-00  Digital Telephony Device Driver
ddrpqio1  Available 1V-08-00  Digital Telephony Device Driver
ddrpqio2  Available 1Z-08-00  Digital Telephony Device Driver
ddrpqio3  Available 1D-08-00  Digital Telephony Device Driver
The first column of the listing shows the name of the item. rpqioadapter_number is a Quad Digital Trunk Telephony PCI Adapter (DTTA) and ddrpqioadapter_number is the associated device driver (where adapter_number is the number of the adapter).

The second column shows whether the adapter and device driver have been correctly configured. Both should be shown as Available (the Defined state means that the adapter has not been detected or configured, or that the device driver has not been configured correctly).

The third column gives the slot position for the adapter. Refer to the manual for your pSeries system for the meanings of this field.

The fourth column describes the item listed in the row.

For Blueworx Voice Response to recognize the DTTA adapters, and to determine whether Blueworx Voice Response is running as T1 or E1, the dt_setowner command has to be issued for each adapter (see Blueworx Voice Response for AIX: Installation for more information).

To check that conditions are correct to start Blueworx Voice Response, type the command:
lsdev -C | grep dtline
AIX will display something like this:
dtline0    Available 1H-08-01        DTTA E1
dtline1    Available 1V-08-01        DTTA E1
dtline2    Available 1Z-08-01        DTTA E1
dtline3    Available 1D-08-01        DTTA E1
where there is one dtlineadapter_number device for each adapter and associated device driver (and where adapter_number is the same as in rpqioadapter_number for the adapter).

To determine the positioning of the physical adapters within a machine, run rpqtest diagnostics (for more information, see Running diagnostics on the DTTA). The orange LED at the bottom of the card will flash at the start of running the diagnostics. This is the easiest way of finding out in which slot an adapter is located in. Diagnostics also need to be run after installing your adapters and before starting Blueworx Voice Response.

If you do not see your DTTA as being available, or if you have been experiencing problems that indicate a possible adapter fault, see Diagnosing unrecognized DTTAs on PCI systems.

Ensure that if you have more than one adapter installed, there is an H.100 cable connecting all adapters together. If you have more than two adapters installed, the H.100 termination jumper should be moved for those adapters which are not at the end of the cable.
