TDM-over-IP packet processors comply with ITU recommendation

19 May 2004 Telecoms, Datacoms, Wireless, IoT

Zarlink Semiconductor claims its ZL50111 family of TDM-over-IP packet processors are the industry's first commercially available devices to fully meet the protocols outlined in the industry's newest recommendation for TDM (time division multiplexing) circuit transmission over packet networks. The ITU recently released Recommendation Y.1413 - TDM-MPLS network interworking - User Plane Interworking. The recommendation outlines the TDM timing, signalling, service quality and alarm integrity required when legacy voice, data and multimedia traffic is carried over an MPLS (multiprotocol label switching) network up to DS3 or E3 rates. Zarlink's the three-chip ZL50111 family uses CESoP (Circuit Emulation Services over Packet) technology to 'tunnel' many forms of Layer 2 TDM traffic over any packet network.
