3   NOTES AND COMMENTS



Note 1 Messages not relating to a signaling link are sent
on the first found available link to the destination.
Note 2 It is the User Part's responsibility to limit traffic
in case of congestion.
Note 3 Automatic allocation or reconfiguration of signaling
equipment is not supported.
Note 4 DCL, CSS, CNS and CNP messages are not supported.
Note 5 This module never initiates sending of TFR.

However, an incoming TFR may lead to TFRs being broadcasted.


Note 6 The following timers are not implemented:

T7, T9, T11, T24.


Note 7 This module provides the necessary statistics/alarms
to generate these measures but does not compute them directly.
Note 8 To be measured/monitored by MTP L2.
Note 9 The total number of this event is measured.
Note 10 Both the total number of MSUs and octets are measured.
Note 11 Changes are made by updating the configuration
file and  send a management order to the module to read the file.
Note 12 TFC and MIM messages are never ignored, that is
we do not fully comply with Section 3.1.2.
Note 13 Standard compliant behavior is a configurable
option. It is possible always to send the priority bits transparently to/from
the User Part or to set to 00 if the node belongs to International network.
