column r/w Enumeration

This variable describes the  variety  of  Zero
Code  Suppression  used  on  the link, which in
turn affects a number of its characteristics.
              
dsx1JBZS(1): refers the Jammed  Bit  Zero suppression
             in  which  the  AT&T specification of at
            least one pulse every 8 bit periods is 
            literally  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.
              
dsx1B8ZS(2): 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.
              
E1 links, with or without CRC, use dsx1HDB3  or
dsx1AMI.
              
dsx1AMI(4): 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.
              
The default value for T1 is 'dsx1JBZS' and for E1 
is 'dsx1HDB3'. 
This field is not applicable for FRSM-VHS cards
and is set to notUsed(5).
