Use the XLOG utility to help diagnose ISDN-related connection problems with Eicon Technology ISDN adapters. The following Eicon adapters maintain a log of connection events in a buffer:
The XLOG utility is located in the SYS:SYSTEM directory. XLOG reads, formats, and writes the buffer contents to an ASCII text file, also stored in SYS:SYSTEM, or displays the buffer contents on the server console window.
To load XLOG, type the following command at the server prompt:
load xlog [adapter] [+|-] [s|d] filename
where
adapter is the name of the ISDN adapter, as specified in NIASCFG.
[+|-] indicates the type of output. The + flag causes XLOG to write continuously to the log file (specified filename ) until interrupted by a keystroke. The - flag causes XLOG to write continuously to the server console window until interrupted by a keystroke.
[s|d] indicates the type of information to record. The s flag causes XLOG to record SIG events only. The d flag causes XLOG to record D-channel events only.
filename is the name of the file where XLOG stores the recorded information. If the file already exists, the new trace overwrites the previous contents of the file.
Use any text editor to view the ASCII-text log file. Each line in the trace contains one event and the time of its occurrence in hours, seconds, and milliseconds (relative to the time XLOG was loaded). The following line shows the format of a recorded event:
HH:SSS:MMM - Event name
Table 13 provides a general sequence of events and a description of the event when a line establishes an outgoing connection.
