Description: This is a two position slide switch used for T1 Interface testing.
Factory Setting: OFF
On: All connections between either the Data Ports or the FXS Ports and the T1 interface are broken and a QRSS pattern is transmitted onto the T1 interface. At this time the T1 Test pattern LED will light when QRSS is being transmitted. (see section on LED).
Note: The T1 test pattern for QRSS only works with framed T1.
Note: The T1 test LED will come on when the QRSS switch is turned ON. When operating the QRSS switch the T1 Loopback switch will be inoperative.
