The AC1 and AC4 are their product families (A – Add drop, C – Cross connect).The AC1 product family consists of STM–1 and STM–4 equipments, where as the AC4 type of equipments has STM–4 and STM–16 equipments. In the AC1 family ADM (Add–drop multiplexer) and TM (Terminal Multiplexer) along with the necessary cross connect functions are implemented in a single module. The same unit also incorporates sufficient dropping capacity, which is upgradable, to make a cost effective solution for small capacity networks. The system has protection facility and utilizes the inherent management capacities of SDH with a ‘Craft Terminal’ (nothing but a PC) or through a fully fledged Network Management System.
