Entity of CS core networkEntity of CS core network
For the ATM and IP transport, there is a strict separation
between the call control level and the bearer control level.
The MSC server shall provide the call control and mobility
management functions
The media gateway shall provide the bearer control and
transmission resource functions. The media gateway shall
contain the stream manipulating functions.

ContextContext
A Context is an association between a collection of
Terminations.
The Context describes the topology (who hears/sees
whom) and the media mixing and/or switching parameters
if more than two Terminations are involved in the
association.
Context ID represents one context

Termination Termination
Termination is a logic entity of MGW, which can receive
and send media or control stream.
Termination can be described into one time slot , IP
address + port number or VPI/VCI

Command: Add/Modify/SubtractCommand: Add/Modify/Subtract
ADD : add one termination into a context
MODIFY : modify the property, event or signaling parameter of the te
rmination ,such as modify codec type, detect offhook /clear signal
SUBTRACT : remove a termination from its context

Command:Move/AuditValue/AuditCapabilitiesCommand:Move/AuditValue/AuditCapabilities
MOVE : move a termination into another context
AUDITVALUE : returns the current values of properties,
events, signals and statistics associated with Terminations.
AUDITCAPABILITIES: return the possible values of
capability of terminations

Command: Notify/ServiceChangeCommand: Notify/ServiceChange
NOTIFY : MGW report the events occurring within the Media
Gateway
SERVICECHANGE
MGW report one or more termination into/out of service.
MGW report the events of restart or logout

Modifying SCTP Checksum Algorithm (Optional)
There are two SCTP checksum algorithms supported in
MSOFTX3000: ADLER32 and CRC32.
Command: SET SCTPPARA
Setting Tone Playing Capability of MGW (Optional)
The command defines the language and cycle times of all tone
clip files played in MGW.
During system initialization, the default setting is loaded that
language is English and cycle number is 2.
