Detailed Product Description

4 x E1 G.703 TDM over IP | E1 over IP | E1 over Ethernet converter | for building a high capacity legacy E1 leased lines over IP networks, Web Manager & with cascading function for capacity increasing.

AN-TDM-IP-4E1 is the new generationof the TDM over IP equipment with IP circuit emulation that supportstransportation of two E1 and two local Ethernet ports over the IPnetwork. The uplink port and user data ports are IEEE 802.3 compliant,10/100BaseT auto-sensed Ethernet ports.

Thestate-of-the-art design provides the highest availability with theaccurate timing signal and data bit stream reconstruction. Predefinedsystem parameter profiles that according to different applicationrequirements ultimately simplify the installation process and savingthe maintenance cost.

Telecom and Enterpriseusers can save a lot of access and equipment costs and generates newrevenue by offering different types of service over existing Ethernetnetworks. It is also suitable for connecting to the wireless equipmentto achieve fast deployment of E1 services. One particular applicationis to build E1 links with low cost Wireless LAN bridges, replacing muchmore costly microwave radios. Operators can use AN-TDM-IP-4E1 to provide legacy TDM services over wired or wireless packet network.

The heart of AN-TDM-IP-4E1is the TDM/Packet processing unit. It truncates E1/T1 data stream,putting the data into Ethernet packet with or without IP headers. Thepackets are passed to the Ethernet switch unit via MII interface, andare sent out adaptive the uplink ports. Ethernet data from two localdata port are also sent out through the uplink ports, but with lowerpriority than those packets containing E1/T1 data.

FEATURES

• Up to 4 E1 or 4 T1 over IP | Ethernet network | TDM over IP converter
• T1 / E1 switch can be done via Web manager utility
  
• Easy to use and convienent Web Manager as a management feature (not available at special economy cost down versions)
• Point to Multipoint feature supported
• Cascading function to increase the capacity - 2 additional Ethernet data ports for downlink
• Stable E1 clock recovery, low jitter and wander
  
• Low processing delay for E1 channels, high bandwidth usage efficiency
  
• Resist to packet loss, with PCM frame synchronization protection
  
• User definable packet size from 128 bytes up to 1408 bytes
  
• Enough jitter buffer to resist packet delay variation (PDV)
  
• Local Ethernet port throughput limiting, assuring E1 QoS
  
• Local and remote E1 LOS and AIS and packet loss indication for trouble-shooting and maintenance
  
• Adaptive E1 port impendence (75 and 120 ohm) for coax and twisted pair cables
  
• User selectable level 2 (Ethernet) or level 3 (IP) encapsulation options
  
• Quick setup hardware mode switch
