13.1.4 Networking Modes of the Integrated SDH

The built-in SDH technology is employed to make even more flexible networking of
the micro-BTS and to address basically various networking requirements. The built-in
SDH is a standard SDH STM-1 optical interface, which supports independent
networking or networking with cooperation of an SDH device. The built-in SDH also
supports directly fiber networking and has ring network protection capability. The
built-in SDH cooperates with the SDH transmission equipment via standard T1
interfaces to flexibly support different networking modes such as point-to-point, chain,
T-type, cross and ring modes and other hybrid networking modes. The built-in SDH
micro-BTS supports independent networking or networking with cooperation of a
standard SDH device.
