This shows who is using the node. It does not show other nodes that are using the node as a level 3 relay, nor does it show those users who have connected to the node but otherwise have done nothing.

The display shows the through connections, followed by those users who are connected to the switch and 'idle'. It also shows those users who are connected to the conferencing facility. The latter stations are shown connected to a destination called 'Talk', whilst in the case of connections, the two endpoints are shown. For connections, two symbols are used, '<-->' and '<..>'. The former is used for established connections whilst the latter is used for connections being established.

When a through connection is established, the "<-->" symbol may be modified if one or other circuit is choked. In this version, the '-' characters will be replaced by another character if one or other link is choked. The first '-' character is associated with the left hand connection ( circuit or uplink ). The second with the other circuit or downlink. A link is 'choked' if one end or the other has signalled that it cannot at the moment accept more data and wishes the sender to pause. It is designed to be used by the sysop in locating network congestion problems.

For a level 2 uplink or downlink, the "-" is replaced by 'C' if the connection is choked. For Level 4 connections, the "-" is replaced by one of 3 characters, "R" if it is choked from the other end, "L" if it is choked from this end or "C" if it is choked from both ends !.
