5.0
The ZL50110/11/12/14 family provides the data-plane processing to enable constant bit rate TDM services to be
carried over a packet switched network, such as an Ethernet, IP or MPLS network. The device segments the TDM
data into user-defined packets, and passes it transparently over the packet network to be reconstructed at the far
end. This has a number of applications, including emulation of TDM circuits and packet backplanes for TDM-based
equipment.
Note: The ZL50110/11/12/14 does not support the transmission or reception of jumbo packets, or packet sizes
larger than 1522 bytes.
