using other methods, the TE is permitted to be supplied with other connection schemes (e.g. connectors).

Justification: Without a connection method defined, it is impossible for the terminal equipment to connect
to the network, therefore this is required for the terminal equipment to interwork with the network
(article 4f).
Currently no standardized connector is readily available. Consequently, the only method of connection that
can be specified in this TBR is the use of solid conductors of 0,4 to 0,6 mm. This TBR requires the TE to
be cap
