"T" BOARD

This board is essentially a T-derivator used for "T" remote terminal connection.

As shown in the picture, the board is equipped with 3 telephone con- nectors and terminals.

By using the "T" board for con- nection to a Remote Terminal, it is necessary to set the J14-J15

Cjumpers on 1-2 position. In this way the electrical feeding is avail- able on all connectors (A-B-C-

2M).

SETTAGGIO PONTICELLI J14 - J15 Posizione 1 - 2

I tre connettori telefonici A - B - C ed il connettore a vite M sono posti in parallelo. L'alimentazione è disponibile su

tutti i connettori.

Posizione 2 - 3

L'alimentazione elettrica presente sui connettori B - C è separata da quella presente sui connettori A - M.

La connessione LAN non viene interrotta tra i vari connet- tori.

Nel caso i due ponticelli J14 - J15 siano posizionati in modo differente il derivatore NON funziona.

JUMPERS SETTING J14 - J15 Set 1 - 2

The three telephone connectors A - B - C and the screw connector M are linked in parallel. The power supply is

available on all connectors.

Set 2 - 3

The electrical feeding of B - C connectors is separate from the one of A - M connectors.

The LAN network is not interrupted among the several connectors.

In case the two jumpers J14 - J15 are set in different position, the T-derivator does NOT work.
