Not to be confused with. A digital cross-connect system (DCS or DXC) is a piece of network equipment, used in telecommunications networks, that allows lower-level, such as bit streams,to be rearranged and interconnected among higher-level TDM signals, such as bit streams. DCS units are available that operate on both older / bit streams, as well as newer bit streams. DCS devices can be used for ' telecommunications traffic, switching traffic from one circuit to another in the event of a network failure, supporting automated provisioning, and other applications.

Having a DCS in a circuit-switched network provides important flexibility that can otherwise only be obtained at higher cost using manual ' cross-connect. It is important to realize that while DCS devices 'switch' traffic, they are not —they switch circuits, not packets, and the circuit arrangements they are used to manage tend to persist over very long time spans, typically months or longer, as compared to packet switches, which can route every packet differently, and operate on micro- or millisecond time spans. DCS units are also sometimes called 'DACS' units, after a proprietary brand name of DCS units created and sold by AT&T's, now. Modern digital access and cross-connect systems are not limited to the, and may accommodate high data rates such as those of. Contents • • • • • • • • • Transmuxing [ ] Transmuxing (transmux: transcode multiplexing) is a telecommunications signaling format change between two signaling methods, typically synchronous optical network signals, SONET, and various time-division multiplexing, TDM, signals.

Transmuxing changes the “container” without changing the “contents.” Transmuxing provides the carrier the capability to embed a telecommunications signal from one logical TDM circuit to another within SONET without physically breaking down the TDM circuit into its components and reconstructing it. There are two types of transmuxing – electrical transmuxing and Optical transmuxing (sometimes called portless transmuxing). In electrical transmuxing, TDM signals (typically DS1/T1 or DS3) are brought in using copper connections, transmuxed to SONET and transported across the network until the reverse occurs. In optical transmuxing, TDM signals (DS1/T1, DS3, OCx) are brought in using fiber optics, transmuxed to SONET and transported across the network until the reverse occurs.

And Japan, DS1/T1 signals are transmuxed into a SONET virtual tributary called a VT1.5. Traffic grooming [ ] Traffic grooming is the process of grouping smaller telecommunications signals into larger. Sulekh Gujarati Typing Software there. This is typically done to minimize the number of connections and circuits needed to optimize the total cost. In TDM, 24 DS0 signals are grouped into a DS1/T1 signal and 28 DS1/T1 signals are groomed into a DS3 signal. A single DS3 signal carries 44.736 Mbit/s of data (672 DS0) and can be sent using a single cable. Circuit switching [ ] Circuit switching is the process of redirecting data signals from one input location to another.

Mixed traffic handling [ ] In a Central Office DCS system, all kinds of signals connect into a DCS. Common signals connecting to a DCS are at the Electrical - DS1, DS3 levels and Optical (OCx) - OC3, OC12, OC48, and OC192.
