Panasonic KX-TDA0480 Installation Manual page 171

Terminal
An H.323 endpoint which provides for real-time, two-way communications which another
Terminal, Gateway, or MCU. A terminal must provide audio and may also provide video
and/or data.
Terminal mode
Terminal mode is one of the operational modes of the Maintenance Console Software. The
terminal mode includes functions like LAN maintenance, emergency maintenance, and
FTP client startup.
Traffic measurement
One of the functions supported by the KX-TDA0480. The KX-TDA0480 has traffic
counters in internal memory. These counters measure the number of originated calls and the
number of terminated calls. Traffic information can be output to the maintenance console.
Trap
One of the signals included in the Simple Network Management Protocol (SNMP). A trap
is sent to the Network Management System (NMS) in the event of an equipment fault for
diagnostic purposes.
TRS
OKI proprietary feature that allows Gatekeeper units to be configured by a system
administrator for routing groups among the stacked/cascaded KX-TDA0480.
UDP
User Datagram Protocol. An unreliable networking layer that sits at the same level of the
networking stack at TCP.
Unreliable Transmission
Connection-less transmission which provides best-effort delivery of data packets. Messages
transmitted by the sender bay be lost, duplicated, or received out of sequence.
Voice compression
A high-quality voice compression function is incorporated in the KX-TDA0480 to achieve
voice communication through the IP network. At the calling side, voice is compressed to 8
Kbps digital signal and then packaged (IP packetisation) and delivered to a router for
transport across the network. On the receiving side, the KX-TDA0480 reassembles the IP
packets and restores them to the digital signal. The original voice is regenerated by
expanding (decompressing) the restored digital signal.
