The output of the csu is the dsx-1 signal the most common csu is found in a t1 mux however they can stand alone with various added functionality the bipolar output of the csu can be connected to a dsu (digital service unit) which converts the bipolar signals to unipolar and vice versa at the data rate gleaned from the bipolar signals. 16 identify the purpose, features, and functions of the following network components: hubs switches bridges routers gateways csu/dsu network interface cards (nics) isdn adapters wireless access points (waps) modems transceivers (media converters) firewalls a wide range of devices is used in modern networking as a.

The csu/dsu implements two different functions the channel service unit (csu) is responsible for the connection to the telecommunication network, while the data service unit (dsu) is responsible for managing the interface with the dte dsl and cable modems are csu/dsus because they convert from one type of digital signal to. The routers are then connected and configured just as they would be in the actual wan environment the csu/dsu or modem provides the clocking for the link using v35 cables in the networkingcompany prototype lab environment, it is possible to simulate a point-to-point wan connection using two serial v35 cables one cable must be a.
The csu/dsu typically adjusts itself to the line speed of the digital data service (dds) line using an autosensing feature the customer’s csu/dsu then connects directly to the customer’s router, and from there connects to the customer’s network at the other end of the dds line at the central office (co), the telco has a similar csu that interfaces.

Csu/dsu csu/dsu is a commonly used of combination of two telecommunications abbreviations csu stands for channel service unit and dsu data service unit the csu / dsu is a digital-interface device used to connect a router to a digital circuit like a t1 or t3 line the csu/dsu also provides signal timing for communication between.
A csu/dsu (channel service unit/data service unit) is a hardware device about the size of an external modem that converts a digital data frame from the communications technology used on a local area network (lan) into a frame appropriate to a wide-area network (wan) and vice versa for example, if you have a web business from your. The dsu provides a modem-like interface between the computer as data terminal equipment (dte) and the csu the data service unit (dsu) manages line control, and converts input and output between rs-232c, rs-449, or vxx frames from the lan and the time-division multiplexed (tdm) dsx frames on the t. Now, csu’s and dsu’s are often combined into one unit ( csu/dsu ) their basic function is to adapt one kind of digital signal into another kind - ie the customer’s digital signaling format into the co’s digital signaling format the csu always connects directly to the telco line, and the dsu sits between the csu and the customer’s equipment.
