[Network] Advanced TCA

Advanced TCA(telecom computing architecture)는 통신 사업자를 위한 컴퓨터의 물리적/논리적인 사양 규격이다. 국제표준 하드웨어를 이용하여 통신사업자의 서비스 개발 기간/비용 삭감을 가능하게 한다. 소형 시스템을 구성하는 μTCA규격도 정해져 있다.
ATCA규격의 Blade는 약 28cm×32cm의 사이즈로 규정되어 있다.

MicroTCA builds on the strength of AdvancedTCA to deliver a standardized platform for smaller systems that need to meet lower-cost parameters. MicroTCA is built around the Advanced Mezzanine Card (AdvancedMC) modules originally developed for AdvancedTCA and other systems.
A key feature of MicroTCA is that it allows multiple packaging options. Unlike standard AdvancedTCA, it meets the 300mm equipment practice. It also supports flexible switching architectures like ATCA, and can be configured to support carrier-grade availability with full NEBS compliance.
This means packaging will be one of the biggest variables in MicroTCA, and there are a number of standard packaging options defined. These include Pico for very small systems, mainly with two or four AMC modules; an 8-inch cube for a fixed configuration with 12 AMCs; and a very flexible 19-inch-rack configuration that can be scaled from about 12 AMCs up to 192 AMCs.

There are 12 AMC modules connected by Gigabit Ethernet, PCI Express, or perhaps some other fabric; and there is also a fabric interface consisting of 21 differential pairs that connects everything together. An AC or 48V DC power module provides switched power to each slot, and a MicroTCA Carrier Hub (MCH) provides the shelf management and switching.
