NETI-CHMGR-MIB Table View

Descriptions on originating connections. The creation and
deletion of rows in the table is done by the application that
provides the service on the connection. When a row is
deleted, the associated rows in the destination table
chmgrODescrDestinationTable and channel table
chmgrODescrChannelTable are also deleted.
          
The table contains information about the capabilities of the
connections as well as the actual configuration of the
connections. As the capabilities depends on the type of
service, it is the service's application that is responsible
for defining these.
          
Changes made on a row in the table will take immediate
effect. This could result in a re-establishment of the
channel(s) using the new parameters.

The table describes destinations for a connection. A unicast
connection can normally only have one destination, while a
multicast connection may have several destinations.
          
If a unicast connection allows alternative destinations, as
defined by the allowAlternative(10) bit in
chmgrODescrCapabilities, it is allowed to define multiple
destinations. At channel establishment, the destinations will
be tried in succession until a channel is successfully
established.
          
It is possible to add, change and delete destinations while
the connection is active. For a unicast connection, a
changed destination is torn down as soon as it is changed,
and established as soon as the changed information contains
valid data. For a multicast connection, it is possible to
add and delete destinations to an already established
connection without affecting the connection to the other
destinations. An added destination will be established as
soon as it includes valid information, and will be
re-established as soon as the information is changed.
          
Note that a destination address with an empty string can be
used to disable the destination. For a multicast connection 
a single destination can also be enabled and disabled using 
its administrative status. 
          
The bits allowAlternative(10), destination(1) and
allowMulticast(3) in chmgrODescCapabilities describes
if and how it is allowed to add a destination to a
connection.

The table describes relationships between destinations
defined in the chmgrODescrDestinationTable, channels and
source routes. To make a connection to a destination 1+1
protected, create two rows representing the two channels in
the table. Note that this is only allowed if the bit
allowProtection(5) is set in chmgrODescrCapabilities.
          
If no conceptual row exists for a destination, it is assumed
that there shall be only one channel to the destination and
that no source route is shall be used.
          
A channel to a destination may have its route through the DTM
networks defined by one or many source routes. If multiple
source routes are defined, any one of these source routes is
chosen when the channel is established.

Table listing source routes. A source route is a route
through the DTM net that is defined at the source of the
channel. The source routes may be used by many connections,
making the connections using the same route through the DTM
network. A source route may only be updated or deleted when
it is not used by any established connection.
          
Note that a source route set up as loose, with no
intermediate nodes, and set up to use any outgoing interface
is equivalent to a shortest path routing.

Table describing the nodes and interfaces for intermediate nodes
that a source route shall be using.

The table lists all the originating connections. The
connections are configured in the chmgrODescriptionTable.

List of destinations per origination connection.

Table that shows the status for all the originating channels, 
listed per connection and destination.

Table with termination connections. The table is managed by
the applications that provide services transported on the
connections.

The channels that exists on a terminating connection.  The
table is managed by the application that provides the service
on the connection. A row is inserted when a new channel is
established and is removed when a channel is torn down. For a
1+1 protected connection, there are two channels in a
connection.

The table shows statistics for originating DCAP-1
connections.  It uses the same index as the
chmgrOConnectionTable. Note that all connections are not of
the type DCAP-1, and are hence not represented in this
table.

The table shows statistics for terminating DCAP-1
connections.  It uses the same index as the
chmgrTConnectionTable. Note that all connections are not of
the type DCAP-1, and are hence not represented in this
table.

Table with all channels, that is originating, transiting or 
terminating channels.
