The Soneplex Test Access Unit (TAU) module is an optional maintenance device that provides monitor and intrusive test access to the DS1 channels in the Soneplex Broadband chassis between the high speed network interface modules and the low speed DS1 distribution modules. | SONEPLEX Test Access Unit The Soneplex Test Access Unit TAU module is an optional maintenance device that provides monitor and intrusive test access to the DS1 channels in the Soneplex Broadband chassis between the high speed network interface modules and the low speed DS1 distribution modules. ADC s Soneplex system is the lowest total cost solution for carriers to grow their T1 business services. Focused on providing flexible end-to-end solutions the Soneplex system saves carriers money on T1-based services over fiber or copper using HDSL ADSL traditional T1 repeater or Optical DS2 technology in a single platform. From operations maintenance provisioning and high-speed backbone connections to central office space and cabling the Soneplex system is designed to take costs out of today s T1 delivery approach adding profit to your bottom line. features Provides bipolar access to DS1 signals Allows monitor drop and insert capability on any DS1 link AMI or B8ZS line codes Front panel controls and LED indicators No provisioning or periodic maintenance required The Soneplex System from ADC. The T1 E1 Service Delivery Experts Ill Soneplex Test Access Unit Description Drop and insert access is provided through Bantam jacks on the Soneplex Test Access Unit front panel and is controlled through the Main Processor Unit MPU craft interface. The TAU requires the B1 DS3 MUX and MPU software Version or later or the SONET Processor Unit SPU Version . It mounts in the Soneplex EC1M VTMM and Version 6 software and mounts into the Soneplex Broadband chassis slot labeled TAU in the high speed section. Two bantam jacks labeled transmit TX and receive RX located on the front panel of the TAU provide a bidirectional industry standard interface to any one of the 28 DS1 signals. The interface may be used with 22 gauge plastic insulated cable PIC up to 133 feet in length. The access is configured through the craft interface for drop or insert of DS1 signals either toward the network .
