GENERAL The ADTRAN Total Access 3010 HDSL Transceiver Unit for the Central Office (LTU), part number 1182007L1, is the Central Office (CO) unit used to deploy an HDSL E1 circuit using 4-wire metallic facilities. See Figure 1. TX M O N E Q RX TX RX ACT A P SGRN = NORM YEL = MAN LP1 TST G703 PWR LP2 ALM LTU 1182007L1 Figure 1. ADTRAN Total Access 3010 LTU The E1 input signal is supplied from the network via individual G.703 lines or an E3 multiplexer. The HDSL signals are provided to the local loop. The Total Access 3010 LTU works in conjunction with the ADTRAN NTU and REG to provide an E1 service up to 9.4 km on the local loop. The LTU works with multiple list versions of the HDSL unit Remote end (NTU) and HDSL Range Extender (REG) as listed below: • 1245043Lx Low Voltage T400 REG • 1245031Lx, Low Voltage T200 NTU • 1245033Lx, Nx64 NTU • 1245044L3, 4th Gen - T400 NTU • 1245035Lx, 5th Gen - T200 NTU The Total Access 3010 LTU can be deployed in circuits consisting of one LTU and one NTU or in a protection configuration requiring two LTUs and two NTUs. When deployment requires the HDSL Range Extender (REG), this LTU can be deployed with one or two REGs and one NTU.

The HDSL local loop operates as two independent subsystems each operating over a single twisted pair. The LTU communicates over these two twisted pairs to the HDSL Transceiver Unit - Remote end (NTU). Each subsystem carries half of the total bandwidth along with a small amount of overhead used for maintenance and performance monitoring. System power and alarm bus connections are made through the backplane of the Total Access 3010 shelf. E1 and HDSL signals are connected through the 50pin shelf connectors related to each individual slot. The LTU contains onboard fuses. If a fuse opens, it supplies a -48 Vdc voltage to the fuse alarm bus and all front panel indicators will be Off. Thes...
