prtT1E1LineCode

This variable describes the  variety  of  Zero
Code  Suppression  used  on  the link, which in
turn affects a number of its characteristics.
              
jbzs=b7zs refers the Jammed  Bit  Zero  Suppres-
sion,  in  which  the  AT&T specification of at
least one pulse every 8 bit periods is literal-
ly  implemented  by forcing a pulse in bit 8 of
each channel.  Thus, only seven bits per  chan-
nel, or 1.344 Mbps, is available for data (used for T1).
              
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 (used for T1).
              
ANSI Clear Channels may use zbtsi, or  Zero
Byte Time Slot Interchange.
              
E1 links, with or without CRC, use hdb3  or
ami (= TRAN).
              
amI (=TRAN) 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  re-
quirements, such as inverting HDLC data.
