DS1/UDS1 (TN767/TN464) Circuit Pack LEDs<br />

The DS1 (TN767) and UDS1 (TN464) circuit packs have four status LEDs on the faceplate in<br />

addition to the three standard faceplate LEDs. These four status LEDs are associated with the<br />

120A Channel Service Unit (CSU) Module which can be connected to the TN767 or TN464<br />

circuit pack through the I/O connector panel on the back of the port carrier.<br />

The TN464 circuit pack, combined with the 120A CSU module or the 401A T1 sync splitter,<br />

forms an Integrated CSU (I-CSU).<br />
