Use this tab to configure the Barr link service for use with SNA Server or HIS. You can access this tab by right-clicking the BARRS1 or BARRX1 link service icon on the SNA gateway's Link Services tab and selecting Properties.
Selects the adapter to use with the BARR link service. BARR/SYNC for Microsoft Networks supports up to four adapters.
Selects the line type based on your communications line, either leased or switched. Use a leased line for data communications. A switched line is a standard telephone line. If you use a switched line, specify how you dial the telephone number. You can choose one of these line types:
Leased
An end-to-end communications line exclusively for your data communications. Also called private line or leased circuit. This option is selected by default.
Switched: manual
A standard telephone line with manual dialing. SNA Server and HIS will prompt you to dial the telephone number.
Switched: modem-stored number
A standard telephone line with dialing through your modem. Your modem must be configured to dial the number when it raises Data Terminal Ready (DTR).
Switched: application-stored number
A standard telephone line where SNA Server or HIS stores the telephone number and dials for you.
Selects the link attributes. The link attributes options are described below.
Service name
The name assigned to the Barr service by SNA Server or HIS (for example, BarrS1 or BarrX1).
Constant RTS
Option for modems that provide a constant Request To Send (RTS) signal. In most cases, selecting Constant RTS will provide higher throughput. You must use Constant RTS for some full-duplex modems. Do not select Constant RTS if you use a multidrop connection.
Distributable
You can allow the Barr SDLC link service to be distributed throughout the gateway's domain. A Distributed Link Service (DLS) lets other gateways share high-speed mainframe access.
DATMODE=FULL
Full duplex is simultaneous, two-way transmission. You can send and receive data simultaneously, which results in twice the throughput. You can even improve one-way throughput because you can receive acknowledgments while you send data. This option is not available for X.25 links.
Multi-drop
If your host connection is provided through a multi-drop or line sharing configuration, use this setting to ensure all devices on the line will be able to function. This option is only available when DATMODE=FULL is selected.
