Card Management
This chapter explains how to configure cards and lines for service delivery.
Configuring Cards
Card parameters control the operational characteristics of the card as a whole. The MGX 8260 Media
Gateway supports the following cards:
• SCC (System Controller Card)
The SCC provides overall system control and database management for the shelf. In addition, the
card provides optional broadband interfaces to the WAN backbone network, such as Fast Ethernet
or SONET. SCCs are always in slots 9 or 10. When SCCs are installed in both slots, they operate
as a redundant pair.
• NSC (Narrowband Service Card)
The NSC adapts different media types and switches signals between carrier networks and services.
The NSC supports a range of service and applications for both voice and data calls. NSCs are
always in slots 1-8 and 11-16.
• BSC (Broadband Service Card)
The BSC adapts different media types and switches signals between carrier networks and services.
The BSC supports a range of service and applications for both voice and data calls, including DS3
circuits. BSCs are always in slots 11-16.
• DMC (Distribution Matrix Card)
The MGX 8260 Media Gateway supports full multiplexing/demultiplexing and TDM-based
switching at DS3 rates through the DMC. The DMC receives DS3 signals and distributes the
services across NSC modules for processing. DMCs are always in slots 7 or 8.
