What is a T1 DSU CSU?
A CSU/DSU (channel service unit/data service unit) is a digital-interface device used to connect data terminal equipment (DTE), such as a router, to a digital circuit, such as a Digital Signal 1 (DS1) T1 line. A CSU/DSU is the equivalent of the modem for an entire LAN.
What is a T1 card?

What is the purpose of CSU DSU?
Description A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts digital data frames from the communications technology used on a local area network (LAN) into frames appropriate to a wide-area network (WAN) and vice versa.
Are CSU DSU still used?
So, external CSU/DSUs have disappeared even for circuits that require them, and circuits that require them have also been replaced by circuits that are terminated with devices that have ethernet interfaces on the customer side.
What is E1 T1?
E1 Overview E1 links are similar to T1 links except that they carry signals at 2.048 Mbps. Each signal has 32 channels, and each channel transmits at 64 Kbps. E1 links have higher bandwidth than T1 links because it does not reserve one bit for overhead. Whereas, T1 links use 1 bit in each channel for overhead.
What is a T1 controller?
the controller is the physical interface. A T1 has 24 channels. The interface se3/0:0 is the first B-Channel out of 24.
What do you need to know about the Cisco 1841 router?
