Description
RX
An optical receiver, which performs optical-to-electrical (O/E)
conversion for CATV and upstream backhaul signals.
TX
An optical transmitter, which performs O/E conversion for received
CATV signals.

channel of signals on an RF port and then sends the signals to the
downstream optical TX.
MAN Network
Concept
Description
Softswitch or IP
multimedia
subsystem (IMS)
Softswitch: core of the NGN network call and control, which supports
call and connection control for the services having high real-time
requirements. For the softswitch, services are separated from call control
and call control is separated from bearing. In addition, the softswitch
uses open service interface (API) and standard protocols, which
facilitates the development for new services and features.
IMS: uses Session Initiation Protocol (SIP) signaling as the call control
signaling. It provides voice, data, and multimedia services.
Broadband TV
(BTV) source
IPTV head end, a contents preparation platform in the IPTV system. It
receives signals, converts media formats, and manages media materials.
