Section 61102040L4-5, Issue 2 61102040L4-5B 1 1. GENERAL This practice provides installation and maintenance information for the ADTRAN SLC-5 U-BR1TE III w/ PWR and DDS Loopbacks (U-BR1TE III).
Section 61102040L4-5, Issue 2 61102040L4-5B 2 • Loopback release in response to TIPs generated from the network direction per TR62310. • Remap all subsequent DS0 DP loopback codes into respective eoc loopbacks to loopback respective downstream U-Repeaters, TRISDN elements, and U-BR1TES when optioned for 1B+D, or 2B+D.
Section 61102040L4-5, Issue 2 61102040L4-5B 3 C A U T I O N C A U T I O N ! SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY. HANDLING PRECAUTIONS REQUIRED. The U-BR1TE III will function with any ISDN 2B1Q U-interface that is ANSI T1.601 compliant.
Section 61102040L4-5, Issue 2 61102040L4-5B 4 NOTE When the U-BR1TE III is optioned for B1 or B2, the SLC-2000 slot must be provisioned for D only. If the U-BR1TE III is optioned for 2B, then the SLC-2000 slot must be provisioned for B1+D. Physical Requirements The U-BR1TE III occupies one physical slot in the SLC-5 or SLC-2000 channel bank.

Section 61102040L4-5, Issue 2 61102040L4-5B 8 Front Panel Features The RJ-45 jack allows front panel test access for local or downstream loopbacks. The address select knob (SW3) determines which element is being looped back. Table 3 lists the loopback options.
Section 61102040L4-5, Issue 2 61102040L4-5B 9 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.
Section 61102040L4-5, Issue 2 61102040L4-5B 10 When the U-BR1TE III operation is normal, the ADR7 position of SW1 does not have a function. NOTE This test option is only available on power up of the U-BR1TE III.
Section 61102040L4-5, Issue 2 61102040L4-5B 11 DS0 DP Loopback eoc Remapping Upon receipt of subsequent DS0 DP loopback codes when the D channel is disabled, the U-BR1TE III remaps the subsequent DS0 DP loopback sequences into the respective ISDN eoc loopback messages.
Section 61102040L4-5, Issue 2 61102040L4-5B 12 Remote End Initiated LBK Tests The U-BR1TE supports loopbacks generated from the IDSL OCU-R which allow testing to be performed without coordination with the CO or test center.
