C150 front and rear
panels The C100 T-1 CSU/DSU can generate and detect five local and remote
loopbacks. (The C150 has seven.) A built-in 2047 pattern generator and
checker is used to self-test the unit as well as test the facility and
remote unit. On the C150, a DSX monitor jack on the Customer
Interface (CI) side provides access for external test equipment.

The C150 has DSX-1 and channel LEDs on the front panel. The
Customer interface signals are different from the C100 front panel.
They are labeled DSX-1 and Channel instead of Data and Control. The
individual LEDs are: LCK, TX, and RX instead if RTS, CTS, and DSR.
The Diagnostics LEDs are also labeled differently from the C100
Loopback and Test LEDs.
