For each Barr remote, your host system programmer must enter the following PU and LU definitions in VTAM. To ensure the correct parameters are used, sample VTAM definitions are provided when you configure the 802.2, HPR/IP, or SDLC communication link. Sample VTAM definitions are not available for MS/LUA connections. See your Microsoft SNA Server or HIS Help for more information.
Before you begin, you must gather the following information from your host programmers. We recommend that you print this topic and record the information in the spaces provided.

Parameter |
Description |
1. LOCADD |
The locally administered address for the network card for the host to which you are trying to reach. |
2. PUNAME |
The PU’s name conforms to the naming convention at your site. The VTAM operator uses the name to vary the unit active or inactive and to query the unit’s status. |
3. IDBLK |
A combination of the IDBLK and IDNUM parameters are used on an 802.2 network to identify the remote’s PU definition. |
4. IDNUM |
A combination of the IDBLK and IDNUM parameters are used on an 802.2 network to identify the remote’s PU definition. |
5. MAXDATA |
The maximum amount of data you can send on the PU in one frame. This count includes nine bytes of header information plus the data length. |
You must add LUs for each printer, punch, and reader, as well as 2 LUs for the RJE Console. Use the LU macro formula to calculate the number of LUs you need.
For each Barr remote, your host system programmer must enter the following PU and LU definitions in VTAM. To ensure the correct parameters are used, sample VTAM definitions are provided when you configure the HPR/IP communication link.

Parameter |
Description |
1. NRZI |
A method to encode binary data using a serial interface. |
2. PUNAME |
The PU’s name conforms to the naming convention at your site. The VTAM operator uses the name to vary the unit active or inactive and to query the unit’s status. |
3. ADDR |
The 8-bit address used by SDLC. This address, the first byte of every frame, separates messages sent to different PUs on the same line. |
4. IDBLK |
A combination of the IDBLK and IDNUM parameters are used to identify the remote’s PU definition. |
5. IDNUM |
A combination of the IDBLK and IDNUM parameters are used to identify the remote’s PU definition. |
6. MAXDATA |
The maximum amount of data you can send on the PU in one frame. This value includes nine bytes of header information plus the data length. |
7. MAXOUT |
Specifies that up to 7 frames of information can be sent before waiting for a response. The maximum MAXOUT value of 7 results in the highest throughput. |
8. DATMODE |
Specifies whether the PU data mode is a full-duplex or half-duplex transmission. |
You must add LUs for each printer, punch, and reader, as well as 2 LUs for the RJE Console. Use the LU macro formula to calculate the number of LUs you need.
If you do not have the ISTATUS=ACTIVE parameter in your VTAM definition, then enter the following commands at your host console.
v net,inact,id=VTAMMEMBER |
Where VTAMMEMBER is the library member that contains the PU definition
