Description
SDH
Synchronous digital hierarchy. SDH is a transmission scheme that
follows ITU-T G.707, G.708, and G.709. It defines the transmission
features of digital signals such as frame structure, multiplexing mode,
transmission rate level, and interface code. SDH is an important part of
ISDN and B-ISDN. It interleaves the bytes of low-speed signals to
multiplex the signals to high-speed counterparts, and the line coding of
scrambling is used only for signals. SDH is suitable for the fiber
communications system with high speed and a large capacity since it
uses synchronous multiplexing and flexible mapping structure.
PTN
Packet transport network. PTN provides bidirectional point-to-point
connections for packet switching services and supports point-to-point
networking using various service granularities. It can use lower-layer
transmission channels such as SDH, Ethernet, and OTN to transmit
services.
BSC/RNC
BSC: Base station controller. A BSC controls a group of base stations
and manages the radio network. Specifically, BSCs manage radio
districts and channels, operate and maintain radio devices, manage
connections of MSs, and provide interfaces between base stations and
the mobile switching center (MSC). Radio control functions can be
integrated in BSCs whenever possible to simplify functions of base
stations.
RNC: radio network controller. RNCs are key NEs on 3G networks.
RNCs manage mobility, process calls, manage links, and switch users
on the access network.
