Introduction
The NTDW20 Media Gateway Extended Peripheral Equipment Controller (MG XPEC) is a dual
card assembly based on Media Gateway Controller (MGC) hardware. It provides control over
line cards in an IPE shelf. The MG XPEC consists of a mother board (MB) and a daughter
board (DB), which operate independently of one another. Each board provides the same
hardware functionality as that of an MGC.
Each card (MB/DB) of the dual-card assembly contains the following features:
• MindSpeed Chagall-2 Processor M82515 to run Nortel proprietary software
• Two on-board M82710 processors, as two High Density DSP DB (on-board), provide 192
DSP Channels with media security
• Ten port Embedded Fast Ethernet Switch
• Two faceplate 100 BaseT E-LAN ports
