column r/w Enumeration

This variable indicates the variety of DS1
Line implementing this circuit.  The type of
circuit affects the number of bits per second
that the circuit can reasonably carry, as well
as the interpretation of the usage and error
statistics.  The values, in sequence, describe:
              
      TITLE:          SPECIFICATION:
      dsx1ESF         Extended SuperFrame DS1
                             (T1.107)
      dsx1D4          AT&T D4 format DS1 (T1.107)

      dsx1E1-CRC      ITU-T G.704, (Table 5B)
      dsxE1-MF        G.704 (Table 5A) with TS16
                             multiframing enabled
      dsx1E1-CRC-MF   G.704 (Table 5B) with TS16
                             multiframing enabled
      dsx1Unframed    DS1 with No Framing
      dsx1E1Unframed  E1 with No Framing (G.703)
      dsx1DS2M12      DS2 frame format (T1.107)
      dsx1E2          E2 frame format (G.704)
      dsx1E1Q50       TS16 bits 5,7,8 set to 101,
                      [in all other cases it is set
                      to 111.] (G.704, table 14)
      dsx1E1Q50CRC    E1Q50 with CRC
      dsx1J1ESF       J1 according to (JT-G704,
                             JT-G706, and JT-I431)
      dsx1J1Unframed  J1 with No Framing
              
For clarification, the capacity for each E1 type
is as listed below:
dsx1E1Unframed - E1, no framing = 32 x 64k = 2048k
dsx1E1 or dsx1E1CRC - E1, with framing,
no signalling = 31 x 64k = 1984k
dsx1E1MF or dsx1E1CRCMF - E1, with framing,
signalling = 30 x 64k = 1920k
