LOGIC BANTAM JACKS
■Used to perform upstream and downstream testing with a DS0 level tester such as a TPI 108/109 or Fireberd 4000/6000.
Rx (OUT) – transmits signal out to unit being tested Tx (IN) – receives signal in from unit being tested

FACEPLATE SWITCHES
Rotary Switch - used to select circuit elements for loopback testing
■AD1 – selects address of local unit for loopback
■AD2 – selects address of next unit downstream for loopback
■AD3 – selects address of second unit downstream for loopback
■AD4 – selects address of third unit downstream for loopback
■AD5 – selects address of fourth unit downstream for loopback
■AD6 – selects address of fifth unit downstream for loopback
■LPBK – forces this unit to set up bidirectional loopback for selected B1 or B2 channel
■CRTX – sets up loopback toward carrier
■LPTX – sets up loopback toward the loop
■NT1 – selects address of the NT1 for loopback
■TEST – initiates selected loopback test from rotary switch

DIP SWITCHES
■B1/B2 – selects which B channel, B1 or B2, to be tested during local tests
■NORM/PTRN – used to select whether test pattern is sent from a test set or the unit itself NORM – test pattern is sent from test set plugged into faceplate bantam jacks
PTRN – test pattern, 2047, is internally generated and transmitted
