When the E1 interface is configured to unbalanced mode, it is connected to the
core of coaxial cables if marked with "+" and it is grounded if marked with "-".
When the E1 interface is configured to balanced mode, it is the positive polarity of
differentiated signals if marked with "+" and it is the negative polarity of
differentiated signals if marked with "-".
When the peer device uses the RJ45 connector, its PIN definitions should be the same as
listed in Table 7-4.
