3   Applications

3.1   LT Mode Testing

In LT mode, the test set emulates the switch (LT) located in the 
central office. This mode can be used to troubleshoot ISDN basic 
rate and IDSL circuits by looping U-BRITE cards, U-repeaters, or 
the NT1 device. Follow this procedure to emulate an LT.
1.  Enter IDSL/ISDN BERT for IDSL testing.
2.  Enter TEST CONFIGURATION and configure as follows:

INTERFACE: U 
MODE: LT-144K
Tx Clock: EXT-U

  Note:  Timing  synchronization  is  extremely  important  when 

testing  IDSL  circuits.  Many  IDSL  circuits  are  transported 
through digital loop carrier systems before they are fanned 
out to individual customer premises. These IDSL circuits are 
typically slave timed from the network clock running on the 
digital loop carrier. If testing an IDSL circuit that is transported 
through a carrier system, select an external clock source for 
the test set, so it will be synchronous to the network clock. If 
a IDSL 2B1Q output signal from the DSLAM is present, select 
EXT-U. If a T1/E1 signal carrying the proper network clock is 
present, then select EXT-T1 or EXT-E1 as appropriate.
TEST CHANNEL: 2B+D (more, F2)
TEST PATTERN: 2047 (press SELECT to change patterns).

3.  Connect the test set to the IDSL circuit. Connect the 2B1Q U 

interface span to the U-2B1Q jack on the module. If an external 
timing source was selected, plug the timing reference into the 
appropriate port. If using timing from the U interface, connect 
the IDSL output from the DSLAM or switch into the U EXT 
CLK module port.

4.  Note the LEDs on the test set. T1/E1 SIG should now be green 

indicating a signal from the U interface. LP 1 SYNC shows the 
status of synchronization. This should be green, indicating that 
the test set has achieved Layer 1 frame sync. If it is red, the 
test set does not have frame sync.

5.  Press ESC and select IDSL/ISDN BERT > EOC CONTROL to 

loopback an NT1 or repeater (U-Brite card) and run a BER test.
A.  At ADDRESS, press NEXT (F2) until the address at the 

right displays the equipment to be looped. First, loop up 
the NT1 device to test the whole 2B1Q span. If errors are 
present, then try looping each U-repeater/ U-BRITE card 
on the span to sectionize the problem. To loop up the NT1, 
make sure ADDRESS reads 0 (NT1).
