HOUSING DIAGRAMS ADTRAN 8-slot AT&T/Keptel/ABACON Above Ground Above Ground Below Ground SPC 6-slot SPC 8-slot AT&T/Keptel Above Ground Above Ground Above Ground POWERING OPTIONS The ICOT will power the entire Total Access 1000 System. When an HRE is used to extend the range of the POTS circuits, a second ICOT is used to provide auxiliary span power to the system through additional copper pairs. (See Figure 1). The Total Access 1000 system continues to receive span power through the HDSL loops. The second ICOT is only needed for its span powering capacity. No circuit information can be accessed from it. No DSX-1 connections are necessary. The loop will not train, and it will always show an alarm condition. Applications using only U-BR1Tes do not require an additional ICOT. WARRANTY ADTRAN will replace or repair this product within the warranty period if it does not meet its published specifications or fails while in service. Warranty information can be found at USA and Canadian customer Faxback: (877) 457-5007, Document 414. COMPLIANCE The 239 HRE complies with the requirements covered under UL 60950 and is intended to be installed in an enclosure with an Installation Code (IC) of “B” or “E.” Ensure chassis ground is properly connected.
