2The XML-based

Advanced Command Line Interface

The XML-based Advanced Command Line Interface, XACLI, is a very flexible interface optimized for both machine-machine interaction and man-machine interaction. It is based on the powerful TANDBERG XML engine and offers many of the same features as the TANDBERG XML interface.

The main distinction between XACLI and the TANDBERG XML interface is the input format. As XACLI is a command-line interface, all inputs from the user/control application have to be put on one line, as opposed to the XML interface where a complete XML document can be posted to the system in one operation.

A basic understanding of the information structuring in the TANDBERG XML engine is important in order to get the most out of the XACLI interface. We therefore recommend you read the TANDBERG XML API section of this document prior to reading this section.

2.1XACLI

2.1.1 Accessing XACLI

XACLI can be accessed through Telnet via the LAN interface or through RS-232 by connecting a serial cable to the serial interface connector, referred to as the Dataport.

UP to 48 Telnet sessions can be active at the same time in addition to the RS-232 connection.

2.1.2 Root commands

For each of the XML documents supported by the system, there is a corresponding XACLI root command. The root command has the same name as the corresponding XML document, except that the root command is prefixed by an “x":

XML document	XACLI root command
status.xml	xstatus
history.xml	xhistory
configuration.xml	xconfiguration
command.xml	xcommand

The information in the TANDBERG XML engine is divided into three main types: Status Information, Configuration Information and Command Information, ref. the documentation of the TANDBERG XML API.

As there is a fundamental difference in these three main types of information, there is also three different ways of working with the information using XACLI.

2.1.3 Addressing

XACLI supports XPath for addressing Status Information and Configuration Information.

In addition there is support for the proprietary TANDBERG SimplePath notation. With SimplePath notation an element or a group of elements are addressed by supplying a space-separated list of element names (elemName) and optional element instance numbers (item):

<elemName> [item] <elemName> [item] ...
