Cisco NM-CEM-4TE1 4-Port T1/E1Circuit Emulation over IP Network Module

The 4-port T1/E1 CEoIP Network Module for the Cisco 2600XM, 2691, 2811, 2821, 2851, 3660, 3700 and 3800 routers provide a new CEoIP service offering. This network modules provide bit-transparent data transport that is completely protocol-independent.

For the first time, this allows network administrators to take advantage of their existing IP network to provide leased-line emulation services, or to carry data streams or protocols that do not meet the format requirements of other multiservice platform interfaces.

Configurable clock source for each port, Optional channel associated signaling (CAS) transport, Emerging standards-based CEoIP based on Vainshtein draft with enhancements, Configurable using Cisco IOS software, Interworking between the T1/E1 and serial network modules, Bit-transparent data transport, Protocol-independent data transport, IP transport using Real-Time Transport Protocol (RTP) and UserDatagram Protocol (UDP) protocol stack, Configurable payload size, Optional payload compression, Optional data protection, Adaptive clock synthesis, Configurable egress de-jitter buffers up to 500 milliseconds Configurable idle pattern Overall network module status LEDs Per-port status LEDs
