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.

CR (Carrier)

Amber

Synchronization over the carrier has not been achieved.

 

Green

Solid in response to a 2B+D loopback. Flashes once per second for B1, twice per

 

 

second for B2 in response to an eoc loopback from the carrier side and during DS0

 

 

logic test when the remote unit has successfully looped over the carrier side, or in

 

 

LPTX or CRTX testing.

 

Off

Synchronization over the carrier has been achieved. No loopbacks or tests are in

 

 

progress.

 

 

 

LP and CR

Amber

U-BR1TE II channel unit has violated the physical slot restrictions or is not

provisioned correctly.

 

Green

BCU has been removed from service or the U-BR1TE II is in special test mode

 

(flashing)

(refer to Local Loopback subsection).

 

 

 

CR (only)

Amber

The channel bank has informed the U-BR1TE II that a network or trunk alarm is

 

(flashing)

present.

 

 

 

ACT (Active)

Green

ISDN Application - Indicates that the terminal equipment has exchanged ACT bits

 

 

with the ISDN switch.

 

 

DDS Application - Indicates loop is terminated with an OCU-R

 

Green

ISDN Application - Once per second indicates that the ACT bit is being sent in one

 

(flashing)

direction only.
