Detailed Product Description

As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, AN-TDM-IP-2E1 adopts the innovative TDM over IP technology, it transports the legacy E1 G.703 data over the existing IP | Ethernet network.

AN-TDM-IP-2E1 is the new generation of the TDM over IPequipment with IP circuit emulation that supports transportation of twoE1 and two local Ethernet ports over the IP network. The uplink portand user data ports are IEEE 802.3 compliant, 10/100BaseT auto-sensedEthernet ports.

The state-of-the-art design provides the highestavailability with the accurate timing signal and data bit streamreconstruction. Predefined system parameter profiles that according todifferent application requirements ultimately simplify the installationprocess and saving the maintenance cost.

Telecom andEnterprise users can save a lot of access and equipment costs andgenerates new revenue by offering different types of service overexisting Ethernet networks. It is also suitable for connecting to thewireless equipment to achieve fast deployment of E1 services. Oneparticular application is to build E1 links with low cost Wireless LANbridges, replacing much more costly microwave radios. Operators can useAN-TDM-IP-2E1 to provide legacy TDM services over wired or wireless packet network.

The AD-TDM-IP-2E1 is a reduced version of AN-TDM-IP-2E1/2D,in that it does not provide local Ethernet ports. Therefore it is morecost-effective, suitable for applications requiring no strict E1channel QoS guarantees over the local Ethernet data, such as to setupE1 links using wireless LAN bridges without the need for providingEthernet services at the same time or in places were the underlyingnetwork bandwidth is abundant.

To emulate a transparent E1 channel over a Ethernet packet networks, the AD-TDM-IP-2E1 notonly conveys data stream content correctly from the source to thedestination, but also passes timing. Packet networks do not providesuch built-in timing transparency mechanism as TDM networks do.AD-TDMOIP uses its proprietary algorithm to reconstruct the E1 clock atthe destination. The recovered clock is of very high quality, with lowjitter and wander. Typical frequency drift is within ?5ppm, and jitteris below 0.1UI. It suits most applications you may need.

Primary applications for the product usage are:

- PABX interconnection via IP & Ethernet networks
- GSM/CDMA backbone development for BS stations, working on E1 interface
- E1 leased line development on existing IP/MPLS or Ethernet networks

FEATURES

• 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
• Fully transparent to all protocols, like PRI, SS7, CAS and other
• Various loopbacks available for testing purposes - local & remote and others
