Returns the current PRI line signal setting.
esf/b8zs
A method of signal encoding used with a T1 interface.
This is the only choice for T1. This value actually
chooses both a framing format and an encoding
method. Legacy frame formats, such as D4, are not
supported. In addition, older encoding methods, such
as B7ZS, are not supported.

This is the default value. Data is encoded using HDB3 to
ensure proper one-density, and CRC4 error checking is
enabled on both transmit and receive.
