An agent may reside at either end of the ADSL line however the       MIB is designed to require no management communication between       them beyond that inherent in the low-level ADSL line protocol.       The agent may monitor and control this protocol for its needs.       ADSL lines may support optional Fast or Interleaved channels.       If these are supported, additional entries corresponding to the       supported channels must be created in the ifTable. Thus an ADSL       line that supports both channels will have three entries in the       ifTable, one for each physical, fast, and interleaved, whose       ifType values are equal to adsl(94), fast(125), and       interleaved(124), respectively. The ifStackTable is used to       represent the relationship between the entries.
