Abstract

Disclosed is a method of display for ISDN (Integrated Services Digital Network) channel status. This method can be applied to a network monitoring device. The B-channel mapping and each layer status can be displayed by using only two or three lines. Each layer status is also expressed by coloring.

Method of ISDN Channel Status Display

      Disclosed is a method of display for ISDN (Integrated
Services Digital Network) channel status.  This method can be applied
to a network monitoring device.  The B-channel mapping and each layer
status can be displayed by using only two or three lines. Each layer
status is also expressed by coloring.

      ISDN Primary interface has much information, so it is important
for user to understand this status information at first sight.

      ISDN Primary interface has twenty-four or twenty-three
B-channels and one D-channel.  This display shows the status of
twenty-three or twenty-four B-channel connections and indications of
each layer alarm status.  The B-channel is mapped by two ISDN
interface ports.  A layer activate indicator displays each layer
alarm status with color.  The colors are Red alarm for 'Inact'
status, Yellow alarm for 'Yellow' alarm and Green alarm for 'Active'
status.

      The figure shows ISDN B-channel connection and each channel
layer indication.  This sample has two line ports of ISDN interface.
The number (1) indicates the channel port number.  #1 is for Port 1
and #2 is for Port 2.  Number (2) indicates each B-channel data of
port 1.  These serial numbers correspond to B-channel numbers.  The
24th number is D-channel data time slot in this case.  And (3)
indicates B-channel mapping data in port 2.  For example, if the 6th
B-channel of port 1 is connected to the 10th B-channel of...
