T1 Interface - T1 Test Pattern QRSS 

(Slide switch - front)

ICX-250 - Front Panel

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.
