ATM4-AMC Controller for ATM to IP Interworking

The ATM4-AMC card is a high performance AdvancedTCA Mezzanine Controller designed for use in all aspects of telecommunications networks. The ATM4 includes support for ATM host termination, switching and L2/L3/L4 or higher interworking between Gigabit Ethernet interfaces and ATM interfaces. With support for AAL2 and AAL5, the ATM4 has the ability for real-time voice and video over AAL2, as well as signaling and IP over AAL5 in 3G/4G networks. The ATM4 is ideal for demanding carrier applications in Wireless 3G, 4G, LTE, IMS, Internet Access, Fixed/Mobile Convergence and Next Generation Mobile Networks such as:

• 4G, LTE-SAE
• WiMAX
• ASN Gateways
• 3G RNC, MSC, SGSN, and NodeB
• Voice over Packet
• Video Streaming
• Broadband Networks (incl GPON)
• ATM to IP Gateways
• Femtocell Access Controller
