SBX PRI Kit

SBX T1/PRI Module with CSU Unit

The T1/PRI interface board board provides a full T1/PRI digital trunk interface and 8 hybrid stations. The board also supports both full and fractional T1/PRI circuits in clusters of 4.

This interface supports either 24 PCM channels for T1 or 23 PCM channels for PRI. Nine (9) loop start CO lines can be used in addition to the T1/PRI channels. The T1/PRI includes the Ethernet port.

This board can be used as either a T1 or a PRI by changing the onboard DIP switch. By default, switch SW4 is set to the ON position (PRI).
