Circuit Emulation over IP

This document provides comprehensive guidance on configuring Circuit Emulation over IP (CEoIP) for Cisco network modules. CEoIP enables the transport of time-sensitive, bit-transparent data streams over IP networks, mimicking leased-line functionality.

Key aspects covered include:

• Understanding CEoIP concepts like adaptive clocking, payload compression, and data protection.
• Prerequisites and restrictions for implementing CEoIP.
• Detailed step-by-step instructions for configuring Cisco NM-CEM-4TE1 and NM-CEM-4SER network modules.
• Configuration examples for various scenarios.
• References for further information, including related documents, standards, MIBs, and RFCs.

The document details how to set up T1/E1 lines, create CEM channels, and establish connections using commands like xconnect. It also outlines essential parameters such as clock source, framing, payload size, and IP QoS settings.
