column Enumeration 
Point in network where last loopback was performed.
              
Meaning for t1 CSU/DSU:
dtePayload - local DSU loopback.  The configured 'fractions'
       of the DS1 signal is looped back as the receive signal.
       Used to verify operation of DSU portion of local 
       CSU/DSU.
dteFull - local CSU loopback.  DS1 transmit signal is looped
       back as the receive signal.  Runs at full bandwidth
       irrespective of fractions configured.  Used to verify 
       operation of local CSU/DSU.
lineFull - DS1 signal received from the network is transmitted
       back to the network.  Signal is regenerated but not 
       reframed.  Loopback performed at the CSU.  Used to 
       verify operation of T1 network.
linePayload - DS1 signal received from the network is
       transmitted back to the network.  Data is regenerated
       and reframed with any LCV or CRC errors corrected.
       Loopback performed at the DSU.  Used to verify 
       operation of local CSU/DSU and T1 network. 
remoteSmartJack - the remote smart jack (telco installed wall
       socket device used to delineate network between CPE and
       telco equipment) is used to loopback the DS1 signal.  
       Similar to remoteFull loopback except that the signal 
       is looped at the smart jack before reaching remote 
       CSU/DSU.   Used to verify operation of local CSU/DSU 
       and T1 network.  
remoteFull - remote unit placed in lineFull loopback.  
       Used to verify operation of local CSU/DSU and T1 
       network. 
remotePayload - remote unit placed in linePayload loopback
       Used to verify operation of local CSU/DSU, T1 network, 
       and remote CSU/DSU.
              
Meaning for switched 56k CSU/DSU:
dteFull - local CSU loopback.  Transmit signal is looped back
       as the receive signal at a point close to the physical
       network interface.  Used to verify operation of local
       CSU/DSU.
lineFull - CSU/DSU is split into separate DTE and loop 
       interface sections.  Signal received from the network 
       is transmitted back to the network.  Data received 
       from DTE is transmitted back to DTE.  Used to verify 
       operation of local CSU/DSU and network from remote site.
linePayload - Signal received from the network is looped
       back at the DTE interface and transmitted back to the 
       network.  Data received from DTE is ignored.  Used to
       verify operation of local CSU/DSU and network from 
       remote site.  
remotePayload - Similar to linePayload except that the
       remote unit is placed into loopback.  Used to verify
       operation of local CSU/DSU, T1 network, and remote
       CSU/DSU.
