|   PRODUCTS   |

Description

Comarra's offers 8/16 x E1 over Ethernet multiplexer (TDM over IP) product supports transportation of 8 E1 or 16 E1s and 5 GE electrical ports and 1 GE optical port. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100/1000M auto-sensing Ethernet ports.

The state-of-art design provides the highest availability with the accurate timing signal and data bit stream reconstruction.

8 E1 and 16 E1 over Ethernet multiplexer (TDM over IP) - Product Brochure (PDF)

Telecom and Enterprise users can save a lot of equipment costs and generates new revenue by offering different types of services over their packet-switched infrastructure. It is also suitable for connecting to the wireless equipment to achieve fast deployment of E1 services. One particular application is to build E1 links with low cost Wireless LAN bridges, replacing much more costly microwave radios. Operators can use 8/16 x E1 over Ethernet multiplexer (TDM over IP) to provide legacy TDM services over wired or wireless Ethernet/IP network.

Features

  • Provides 8E1 and 16E1 ports (available in 1E1, 2E1, 8E1 and 16E1 versions)
  • Supports point-to-point and point-to-multi-point applications
  • Provides 5 GE electrical ports and 1 GE optical ports
  • User-friendly web server supported for easy setup and maintenance, Alarm logs provided

(B) Typical Application in Wired Network

This configuration guarantees that the E1 channels get higher priority over computer data for maximum QoS.

The most widely used application of 8E1/16E1 x E1 over Ethernet multiplexer is to set up point to point wireless E1 links using low cost wireless LAN bridges or Ethernet RPR fiber links. 8/16 x E1 over Ethernet multiplexers can work with most LAN bridges available in the market. It may be necessary to adjust different parameters such as packet size and packet jitter absorption buffer size for best operation for different LAN bridges.
