Signal Pinout (SB) MB The ADTRAN TRDDB plugs directly into a WECO or equivalent D4 channel bank or the ADTRAN ACT 1900/2300 channel bank. No special wiring is required. The 2-wire loop is connected using the Tip (pin 24) and the Ring (pin 51) on the D4 backplane. -

Refer to Table 2 for LED indication. Figure 6. Rate Selection and Option Switch Table 2. LED Indicators False Loopback Immunity ADTRAN’s Protected Loopback family of channel i l a units include an algorithm compatible with SARTS, l a t Hekimian, TPI, and other test systems that virtually eliminates false latching loopback occurrences. -
Page 5: Testing
Cable loss data based on wire type and temperature for the Total Reach DDS Nyquist frequency of 13.3 kHz is listed in Table 4. The ADTRAN TRDDB front panel is equipped with logic level bantam test access jacks that permit testing i t c in both directions using a portable test set. -
Page 6: Figure 7. Trddb Bidirectional Loopback Pass-Thru Mode
TRDDB Bidirectional Loopback Support Table 6. Alternating Loopback Activation The TRDDB will execute a bidirectional loopback Sequence when performing a DS0 loopback at the TRDDB (Figure 7). If the TROCU-R detects a bidirectional loopback during power up synchronization, the i t c TROCU-R allows data to pass on the 4-wire interface i f i by entering pass-thru mode (Figure 7). -
Page 7: Remote Provisioning And Diagnostics
Remote access to provisioning and status information loopback at the TRDDB towards the customer. See is accomplished using ADTRAN Digital System 6 Figure 9. This allows data to be sent from the remote Message protocol, defined in Control and Diagnostic end to test the local loop and the TROCU-R. -
Page 8: Deployment Guidelines
5. DEPLOYMENT GUIDELINES Remote access is accomplished using a defined set of in-band DS0 byte sequences similar to the latching The TRDDB and TROCU-R use technology intended loopback sequence. Commands issued through the to eliminate the need for repeaters and concerns over test system are recognized by the individual channel impairments caused by typical noise and bridged taps. -
