The MIB module defining objects for the management of a pair of ADSL modems at each end of the ADSL line. Each such line has an entry in an ifTable which may include multiple modem lines. 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.
