Parameter Description
get Returns the current PRI line signal setting.
set Sets the PRI line signal. It requires one of the following
parameters:
esf/b8zs , crc4/hdb3 , hdb3
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.
crc4/hdb3 A method of signal encoding used with an E1 interface.
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.
hdb3 A method of signal encoding used with an E1 interface.
CRC4 error checking is disabled.
