Digital Access and Cross-Connect System (DACS)

Definition - What does Digital Access and Cross-Connect System (DACS) mean?

A digital access and cross-connect system (DACS) is a telecommunication-specific circuit-switching device that is used to route voice/data among cross-connected T1/E1 carrier lines.

DACS is used in telecommunication networks to connect various carrier channels that exist in voice and data carriers. DACS enables these carriers to connect with each other and their specific channels as well. DACS supports connectivity among DS0 and DS1 channels used for transporting voice and data/voice respectively. DACS also supports higher level carriers such as T3/E3, synchronous optical networking (SONET) and synchronous digital hierarchy (SDH).

Techopedia explains Digital Access and Cross-Connect System (DACS)

Telecommunication companies around the globe use voice and data carrier lines to enable communication within their network and with other networks. These carriers are dedicated telecom connections that support multiple channels. T1/E1 lines are a popular carrier that have the ability to transfer both data and voice at the same time.

DACs enables connectivity among different T1/E1 lines and has built-in abilities to connect channels. DACS can also cross-connect higher level data channels (such as DS1) with lower levels (like DS0).
