The MIB for providing information specified
in ITU Q752 Monitoring and Measurements for
signalling System No. 7(SS7) Network. 
This information can be used to manage messages
transported over SS7 Network via Cisco IP 
Transfer Point.  
        
The Cisco IP Transfer Point (ITP) is a hardware 
and software solution that transports SS7 traffic 
using IP. Each ITP node provides function similar
to SS7 signalling point.   
        
The relevant ITU documents describing this technology
is the ITU Q series, including ITU Q.700: Introduction
to CCITT signalling System No. 7 and ITU Q.701 
Functional description of the message transfer part
(MTP) of signalling System No. 7.
        
The ITP Quality of Service (QoS) model allows the
definition of 8 QoS classes, 0 through 7.
QoS classes can be assigned only SCTP links.
Only one QoS class can be assigned to an SCTP link.
Class 0 will be designated as the default class.
Packets that are not classified to a designated QoS
class will get assigned to the default class. Each
provisioned QoS class can be assigned an IP precedence
value or a Differential Services Code Point (DSCP).
The default  class is initialized to IP precedence
zero (0). The default class initial TOS setting can
be changed through the command line interface. The
Type of Service (TOS) byte in the IP header will be
set to the IP precedence or DSCP that is assigned to
class. Every packet forwarded over an SCTP link that
was provisioned for a given QoS class will have the
TOS byte set.
