Setting ownership of the DTNAs

This section assumes that you have four DTNAs installed in your system unit. DTTAs can be installed alongside DTNAs (up to a maximum of four adapters). For more information on setting ownership of DTTAs, and for example output for these adapter types, see Blueworx Voice Response for AIX: Installation.

If you are using DTNAs with Blueworx Voice Response VoIP, you need to set Blueworx Voice Response as the owner of these adapters.

Log on to AIX as root, if you are not logged on already.
Ensure that Blueworx Voice Response is not running (for example, by typing ps -ef | grep NODEM)
Type the following command and press ENTER:
```
. /usr/lpp/dirTalk/tools/vae.setenv
```
Make sure that you leave a space between the . (period) and /usr.
You need to create a device for each of the DTNAs you want installed in the system unit and register Blueworx Voice Response as the owner of each of these devices. Up to four DTNAs can be installed in a system unit where each DTNA adapter provides support for four trunks, giving a total of 16 trunks.
The dt_setowner command is used to create and register these devices. When installing a DTNA, you need to supply three options to the dt_setowner command: the adapter type (-n) for DTNA, the adapter number (-s), and the trunk type (-t), which can be either T1 or E1.
For DTNA, the dt_setowner command is in the format:
```
dt_setowner -n -s adapter_number -t T1 | E1
```
where adapter_number is the last digit of the device identifier, starting at 0 for the first adapter and increasing by 1 for each subsequent adapter up to a maximum value of 3.
For example, to create four T1 DTNA adapters and register Blueworx Voice Response as the owner, type the following commands, pressing Enter after each one:
```
dt_setowner -n -s 0 -t T1
dt_setowner -n -s 1 -t T1
dt_setowner -n -s 2 -t T1
dt_setowner -n -s 3 -t T1
```

Note: If you have DTTA PSTN adapters in the same machine, DTNAs must be configured as the same type (T1 or E1).

If you only have DTNA in the machine, the preference is to use T1 in US or Japan and E1 in the rest of the world. The advantage of E1 is that it allows the full 120 channels of DTNA to be used. However there may be complications which must be carefully considered as the internal mode of operation of Blueworx Voice Response will now be A-law rather than the natural mode of μ-law for T1.

If you have DTTA PSTN adapters in the same machine, ensure that the DTTA and DTNA adapters are configured to use different addresses.

For more information on using dt_setowner, see Blueworx Voice Response for AIX: Installation.

Each dt_setowner command creates three AIX devices:

A DTNA ‘adapter’ vnaio<n>
A DTNA device driver ddvnaio<n>
A Blueworx Voice Response line device dtline<n>

(Check using lsdev –C | egrep “vna|dtline”).

The following is an example of a session which sets up two DTNA adapters:

You must now install, or check the installation of, the VoIP/SIP custom server. See Software installation.
