established. If the Link State field is "Up," then the CDR Link may be using
one of the Network Control Data Channels (DATA-CHLs).

subsection on Page 2 of the resulting form. Note the values in the Primary
Output Extension and Secondary Output Extension fields. If the values are
extensions, then the CDR Link is using one of the Network Control Data
Channels (DATA-CHLs).
3. For each of the extensions in the Primary Output Extension and Secondary
Output Extension fields, issue the status data-module <ext> command
using the extension. Note the value in the Connected Ports field of the
resulting form. If there is a port value in the field, then the indicated port is
a Network Control Data Channel (DATA-CHL).
4. Issue the list data-module command, locate each port indicated in the
Connected Ports fields, and determine if that port has a "type" value of
"netcon." If so, then there is an CDR Link over that DATA-CHL.

Output Extension fields, issue the status data-module <ext> command
