Network devices


Introducing our network devices facilitates smooth migration to IP networks and provides inexpensive L2VPN.

Establishes optimum networks suitable for the broadband era with a wide lineup ranging from legacy to de facto standard equipment.

A method to smoothly migrate current intranets to IP networks and integrate them with current operations without changing existing interfaces has become a challenge for customers.

  1. Existing interfaces can be migrated to IP networks, or operations conducted with synchronous networks can be established by utilizing IP networks.
  2. Customers can build new network environments in which they can easily use IP phones by simply connecting telephones to the new networks.
  3. Ethernet VPNs can be readily built economically with the use of dedicated terminals by utilizing broadband lines.

POINT (1) Clock transmission has been achieved using IP networks!

Our network devices allow data compliant with TTC standard JT-I431-a/G703 or data transmitted through PBX's OD trunks (4-wire) to be transmitted via IP networks.

POINT (2) SIP is used to enable VoIP services, allowing multiple analog type telephones and facsimiles to be accommodated.

POINT (3) Dedicated hardware has achieved high-speed data throughput!

An L2VPN connecting a maximum of 30 sites can be built and very easily configured due to the use of dedicated terminals.

Model Name :

Circuit Emulation Service (CES)-TA Equipment converts data compliant with JT-I430-a or JT-I431-a to 10BASE-T (IEEE802.3)/100BASE-TX (IEEE802.3u)/optical interface data and transmits the converted data.
This CES-TA equipment functions as a slave to the ODN-512 clock transmission equipment based on the TDM over IP technology through private or wide-area Ethernet networks, configuring systems based on a point-to-point connection basis.
