                 dsx1LineIndices with an unique identifier

                 dsx1JBZS 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 channel, or 1.344 Mbps,
                 is available for data.

                 dsx1B8ZS 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.

                 ANSI Clear Channels may use dsx1ZBTSI, or Zero
                 Byte Time Slot Interchange.

                 E1 links, with or without CRC, use dsx1HDB3 or
                 dsx1AMI.

                 dsx1AMI 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.

                 dsx1B6ZS refers to the user of a specifed pattern
                 of normal bits and bipolar violations which are
                 used to replace a sequence of six zero bits.  Used
