259.0. "Twisted pair pinouts." by KERNEL::HOGGAND () Thu Jun 03 1993 05:44

    Hi,
    
    A simple query really; what are the pinouts for twisted pair terminals
    and twisted pair drop cables?
    
    If you were to plug a terminal into a twisted pair repeater port, I
    understand that the repeater should segment that from the rest of the
    network - is this actually true of the DECrepeater 90T?
    
    Dave.

    To answer my own question.
    
    	Ethernet			Device
    
    1	Tx +				Rx GND
    2   Tx -                            Rx
    3   Rx +                            Tx GND
    4    -                              CTS or RI
    5    -                              RTS or DSRS
    6   Rx -                            Tx
    7    -                              DTR
    8    -                              DSR or DCD
    
    Where two options exist, the second set can be selected by changing the
    signal select characteristic.
