             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.
