Preliminary Data Sheet

ISDN Network Termination Node (NTN) Device
15 Test Mode
When the TEST pin (pin 43) is asserted, pins 34, 85, and 97 change their existing functions so that the customer
can put the device in ILOSS, single pulses on the U-interface, and pulse template/loopback on S/T-interface test
modes, respectively.
When the TEST pin (pin 43) is asserted, pins 29, 30, 32, 35, 40, 41, and 42 also change their existing functions to
enable factory testing of the device as explained in Table 3 and Table 7.
Note: The existing functions on the above pins will not be available when the TEST pin is asserted.
