SISA/QD2

'SISA' stands for 'Supervisory and Information System for local and remote Area' and refers to a communication network for controlling and monitoring telecommunication facilities such as SDH, PDH multiplexers. SISA/QD2 is a hierarchically organized network dispatching information between network elements (NE) and corresponding operation systems (OS).

SISA/QD2 was standardized by the FTZ (German Telecommunication Engineering Authority, now ZZF) as per the FTZ standard N 13-5.

Its physical interface is called QD2.
