column Enumeration

Current ISDN BRI integrated U interface Loop status and
NT maintenance mode.  The definition of maintenance modes 
are as follows:
none - The U interface is not in either Loopback or
     maintenance mode.
type2Loopback - Type 2 (CO to U interface) Loopback
     mode; this mode is set to perform the loopback between
     CO and the ISDN BRI integrated U interface.
type3Loopback - Type 3 (processor to U interface) Loopback
     mode; this mode is set by router to perform the loopback
     between the router processor and the ISDN BRI integrated
     U interface.
ntQuietMode - NT quiet mode; this mode is set by CO for
     metallic loop tests. In the NT quiet mode, the ISDN U 
     interface will not attempt a start-up or will not 
     initiate transmission during metallic loop tests 
     conducted by the network.
ilmtMode - Insertion loss measurement test (ILMT); this mode 
     is set by CO for the Insertion loss measurement test. 
     The insertion loss measurement test will cause a known 
     test signal to be generated by the NT. This test will 
     be used in network measurements of DSL (Digital 
     Subscriber Line) transmission characteristics.
