            management of ISDN interfaces."
       ::= { transmission 20 }

-- The ISDN hardware interface (BRI or PRI) is represented
-- by a media specific ifEntry.
--
-- For basic rate lines, the media specifics for the physical interface
-- is defined in the physical interface group of the ISDN MIB.
-- The ifType for physical basic rate interfaces is isdns(75)
-- or isdnu(76), whichever is appropriate.
--
-- For primary rate, the media specifics are defined in the Trunk
-- MIB and the ifType has a value of ds1(18).

-- Each signaling channel is represented by an entry
-- in the isdnSignalingTable.
-- The signaling channel has an ifType value of isdn(63).
-- Each B channel is also represented as an entry
-- in the ifTable. The B channels have an ifType value
-- of ds0(81).
-- This model is used while defining objects and tables
-- for management.
-- The ISDN MIB allows sub-layers. For example, the data transfer
-- over a B channel may take place with PPP encapsulation. While the
-- ISDN MIB describes the D and B channels, a media specific MIB
-- for PPP can be used on a layered basis. This is as per
-- the interfaces MIB.
