Enumeration
In T1 mode the primary rate interface is able
to work with different line codes.
e1-hdb3(1) High Density Bipolar 3 Level Coding
This is the only valid linecoding for E1
t1-b8zs(2) Bipolar 8 Zero Substitution
B8ZS refers to the use of a specified
pattern of normal bits and bipolar
violations which are used to replace a
sequence of eight zero bits
t1-ami(3) Alternating Mark Inversion.
AMI refers to a mode wherein no zero code
suppression is present and the line encoding
does not solve the problem directly. In this
application, the higher layer must provide data
which meets or exceeds the pulse density
requirements, such as inverting HDLC data.
t1-linecodes can only be set when pmxIfLayer1Mode is t1
e1-linecodes can only be set when pmxIfLayer1Mode is e1
The default linecode for t1 is t1-b8zs
