To initiate a point-to-point test, perform the
following:
1. Connect the DS0 digital tester to the RJ-45 jack.
2. Configure the test set for Near Logic and 64kbps.
3. Select the desired test direction and bearer
channel using the address select knob.
4. If the far-end unit is a SLC-5 U-BR1TE III,
perform steps 1-3, choosing the same front panel
selections. Ensure both test sets are configured
for the same test pattern (511, 2047).
5. If the far-end is another device, follow the
appropriate directions to provide a point-to-point
test.
Local Loopback
The U-BR1TE III incorporates a special test mode to
provide a local 2B+D bilateral loopback. Once
invoked, this test allows an upstream and downstream
test set to send a straight-away test pattern. To put the
U-BR1TE III into this test mode, select ADR7 on the
address select knob and insert the channel unit into the
channel bank. The CR and LP LEDs will flash
GREEN once the U-BR1TE III is in this special mode.
To discontinue the special test mode, turn SW3 in
either direction deselecting the ADR7 position. This
will cause the unit to reset and return to normal
operation.
