MSC(Mobile Switching Center) ACX-2000(3G 1x RTT)
Overview
| Modular H/W and S/W which allows easy expansion |
|
| Adoption of the open architecture for various network interfaces |
| Multiprocessor structure (function distribution and load distribution) |
| Distributed control structure and system redundancy |
| Evolution from 2G MSC (H/W, S/W upgrade) |
| Simultaneously supports 2G / 3G BSC |

| Key Features |
* Multiprocessor structure: function and
load distribution |
* Distributed control structure: 2-level
control layer structure
(high-level processor: MP, low-level processor:
PP)
- MP: call handling, number translation, switchnig
control, system operation and maintenance
- PP: speech path monitoring, analysis, signal
processing |
| * Parallel processing operating system:
CROS to support CHILL |
| * Redundancy: MP, PP, communication controller,
time switch, space switch, network synchronizer |
| * OMID (Operation & Maintenance Interface
Device) implementation |
| |
|
| |
| Functions |
* Call control and mobility management |
| * Call features and supplementary services |
| * Operation, administration and maintenance |
| * Interface to PSTN / ISDN / PLMN / PSPDN |
| * Interface to OMC / NMS / Billing system |
| |
|
| |
| Benefits |
* Modular H/W and S/W which allows easy
expansition |
| * Adoption of open international standards:
IOS 4.0, ANSI-41E, TCP/IP, TMN Q3 |
| * 2G and 3G technology interoperability
with one system |
