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.
High-speed digital leased line services can be replaced without changing user interfaces.
The CES-TA equipment absorbs delay fluctuations of received clock packets and regenerates synchronous clocks with suppressed jitter, achieving the synchronization of networks.
The CES-TA equipment has a built-in optical interface, facilitating the control and maintenance of networks.
Maintenance: TS-1000 and EtherOAM (IEEE802.1ag/ITU-T Y.1371) compliant
The loop back testing of the CES-TA equipment can be achieved by sending loop test settings from the clock transmission equipment.
