-- The Channel Group
--
-- Implementation of every object in this group is mandatory.

-- Channels are independent sources of print data. Here,
-- print data is the term used for the information that is
-- used to construct printed pages and may have both data
-- and control aspects. The output of a channel is in a form
-- suitable for input to one of the interpreters as a
-- stream. A channel may be independently enabled (allowing
-- print data to flow) or disabled (stopping the flow of
-- print data). A printer may have one or more channels.
--
-- Basically, the channel abstraction is intended to cover
-- all the aspects of getting the print data to an
-- interpreter. This might include transporting the data
-- from one place to another, it might include (invisible)
-- compression, it might include encoding or packetizing to
-- provide multiple information sources over a single
-- physical interface and it might include filtering
-- characters that were destined for another kind of
-- channel. All of these aspects are hidden in the channel
-- abstraction.(Note some Page Description Languages have
-- compression built into them so "invisible" compression
-- refers to compression done by the transport medium and
-- removed before the data is presented to the interpreter.)
--
-- There are many kinds of channels;some of which are based
-- on networks and others which are not. For example, a
-- channel can be a serial (or parallel) connection; it can
-- be a service, such as the Unix Line Printer Daemon (LPD),
-- offering itself over a network connection (interface); or
-- it could be a disk drive into which a floppy disks with
-- the print data is inserted. Each channel is typically
-- identified by the electronic path and/or service protocol
-- used to deliver print data to the printer.
--
-- Channel example                   Implementation
--
-- serial port channel            bi-directional data channel
-- parallel port channel          often uni-directional channel
-- IEEE 1284 port channel         bi-directional channel
-- SCSI port channel              bi-directional
-- Apple PAP channel              may be based on Local-, Ether-or
--                                TokenTalk
-- LPD Server channel             typically TCP/IP based, port 515

Top      Up      ToC       Page 69 
-- Novell Remote Printer          typically SPX/IPX based channel
-- Novell Print Server            typically SPX/IPX based channel
-- port 9100 channel              HP and friends
-- Adobe AppSocket(9101) channel  a bi-directional extension of LPD
--
-- It is easy to note that this is a mixed bag.  There are
-- some physical connections over which no (or very meager)
-- protocols are run (e.g. the serial or old parallel ports)
-- and there are services which often have elaborate
-- protocols that run over a number of protocol stacks. In
-- the end what is important is the delivery of print data
-- thru the channel.
--
-- The channel sub-units are represented by the Channel
-- Group in the Model. It has a current Control Language
-- which can be used to specify which interpreter is to be
-- used for the print data and to query and change
-- environment variables used by the interpreters (and
-- Mangement Applications). There is also a default
-- interpreter that is to be used if an interpreter is not
-- explicitly specified using the Control Language. Channel
-- sub-units are based on an underlying interface.

--       The channel table and its underlying structure
--
-- The first seven items in the Channel Table define the
-- "channel" itself.  A channel typically depends on other
-- protocols and interfaces to provide the data that flows
-- thru the channel. It is necessary to provide control of
-- the (perhaps complex) process by which print data arrives
-- at an interpreter. Control is largely limited to enabling
-- or disabling the whole channel. It is likely, however,
-- that more control of the process of accessing print data
-- will be needed over time. Thus, the ChannelType will
-- allow type specific data to be associated with each
-- channel (using ChannelType specific groups in a fashion
-- analogous to the media specific MIBs that are associated
-- with the IANAIfType in the Interfaces Table). As a first
-- step in this direction, each channel will identify the
-- underlying Interface on which it is based. This is the
-- eighth object in each row of the table.

-- Some examples of the kind of control are where
-- compression or encoding is used; and whether the data is
-- filtered to remove file storage anomolies such as those
-- created by using MS-DOS/PC-DOS LPT1:.

Top      Up      ToC       Page 88 
                      and its sub-units. An example of a technical

                      trained by the manufacturer or similar
                      representative.
               Trained - Alerts that require an intermediate or moderate
                      level of knowledge of the printer and its
                      sub-units. A typical examples of alerts that
                      a trained operator can handle is replacing
                      toner cartridges.
               Untrained - Alerts that can be fixed without prior
                      training either because the action to correct
                      the alert is obvious or the printer can help the
                      untrained person fix the problem. A typical
                      example of such an alert is reloading paper
                      trays and emptying output bins on a low end
                      printer.
               Management - Alerts that have to do with overall
                      operation of and configuration of the printer.
                      Examples of management events are configuration

    STATUS     current
    DESCRIPTION
        "An index of the row within the principle table in the
        group identified by prtAlertGroup that represents the
        sub-unit of the printer that caused this alert.  The
        combination of the Group and the GroupIndex defines
        exactly which printer sub-unit caused the alert.; for
        example, Input #3, Output #2, and Marker #1.

        Every object in this MIB is indexed with hrDeviceIndex and
        optionally, another index variable.  If this other index
        variable is present in the table that generated the alert, it
        will be used as the value for this object.  Otherwise, this
        value shall be -1."

        "The sub-unit location that is defined by the printer
        manufacturer to further refine the location of this alert
        within the designated sub-unit.  The location is used in
        conjunction with the Group and GroupIndex values; for
