Media Gateway Features
- Common APIs for different Gateway protocols
- Multiple packaging options - H.248 1.0, NCS compliance
- Suited to both IP and ATM networks through abstraction
of Stream Management
- Easy means of plugging new packages for extensibility
- Abstraction APIs for DSP and Telephony Signaling
functions
- Platform independent - hardware and software
Aricent's Media Gateway Toolkit: Carrier Grade Features
- Loosely coupled architecture enables scalable configurations
- Toolkit and application can be on same or different
processors
- Internal modules of the toolkit can be distributed
- Single stack can service multiple Protocol
Processing Components
- Interfaces can be extended from Message to
Function-based
- Data Structure scalability through advanced search
algorithms
- Multi-threaded termination handling for increased
load and performance
- Optimised schemes for memory access to avoid memory
copies
- Re-dimensioning support
- Built-in N:K Redundancy solution
Application Scenarios
- Trunking Gateways
- Access Gateways
- Residential Gateways
Interoperability
With leading vendors through interoperability events
or testing in Aricent labs
Aricent's Media Gateway Toolkit: Components
- Protocol Stack Module implements the encoding/decoding
and parameter validation functions for the Gateway
Control Protocol. It also provides Transport Management,
Association Management, Transaction Management functions
- Protocol Processing Module implements the protocol
processing functions like handling of contexts/ terminations
or connections/endpoints, events and signals, digit
collection and digit map processing
Aricent's Media Gateway Toolkit: Interface
The Toolkit exposes a generic set of interfaces for
integration with other modules in a Media Gateway solution.
The following interfaces are exposed:
- Resource Management APIs include support
for resource allocation and de-allocation for SCN/
PDN terminations. The resources assumed by the MG
PPU are DSP, DSP Channel, Connection address and Port
numbers. In addition, Resource connection and Topology
implementation requirements are also sufficed through
this set of APIs exposed by MG Toolkit
- Connection Management APIs trigger connections
within the Media Gateway between resources and terminations
- Stream Management APIs expose the stream
creation, deletion and modification of stream-properties/stream-mode
processing triggers from the MG Toolkit
- Package Management APIs define generic interface
between the MG Toolkit and a generic package-processing
module Package Processing modules realize one or more
Protocol specific packages (MEGACO/ MGCP)
- Configuration Management APIs include support
for MG Protocol related configuration, MG Protocol
package specific configuration, MG-MGC Association
configuration, MG termination configuration, MG state
management functions, i.e., modifying the termination
state and the MG-MGC association state from the user
perspective
- Alarm-Trace-Statistics Management APIs are
exposed to the System Management Entity for configuration
of MG PPU Alarms and Traces, for requesting MG PPU
statistics/status and for reporting of MG PPU alarms,
traces, statistics and status
- OS Porting APIs expose memory, timer, semaphore
(mutex) and thread-related operating system dependent
services
