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 T1 E1 card?
T1 is a digital carrier signal that transmits the DS – 1 signal. It has a data rate of about 1.544 megabits / second. T1 is the North American term whereas the E1 is the European term for the transmission (digital). The data rate of E1 is about 2 mega bits per second. It has 32 channels at the speed of 64 Kbps.
