Marketing Information
  • The 4-port Serial 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.
