Chapter 1 Overview 1.1 Introduction Purpose This manual describes the technical characteristics, application, installation, and operation of the D8E1T1 used in the DXC-100 Multiservice Access Node. D8E1T1 is an 8-port E1/T1 module that supports up to eight E1 or T1 links, in any combination, with D4 (SF), ESF or G.70x framing and AMI, B8ZS or HDB3 line coding. The module has integral BERT and supports loopback diagnostics. 10:1 hardware redundancy is available via the DXC-100PSX unit.
D8E1T1 Installation and Operation Manual Chapter 1 Overview Thumbscrews at the top and bottom of the panels secure the modules in the chassis and make electrical connection to frame ground for regulatory emission compliance. The electrical connection to frame ground also protects the modules from static discharge. Top and bottom card ejectors on the application module facilitate its removal (and insertion).
D8E1T1 Installation and Operation Manual Chapter 1 Overview Other LED Indications When all front panel LEDs are cascade lighting from top to bottom, the module is downloading software to memory. Caution Do not interrupt the software upgrade while it is in progress, otherwise the D8E1T1 module configuration may be damaged. In the event of damage, please contact RAD Technical Support Department. If all front panel LEDs are off except the READY LED, it indicates that all links are Out of Service.

D8E1T1 Installation and Operation Manual Chapter 4 Troubleshooting and Diagnostics 4.4 BERT (Bit Error Rate Test) BERT is used to test the bit error rate of the communication circuit. The device checks for errors by comparing a received data pattern with a known transmitted data pattern to determine transmission line quality. If a pattern match cannot be found, Errored Seconds counts are incremented to record the time during which a pattern lock in the receive path could not be established.

D8E1T1 Installation and Operation Manual Chapter 4 Troubleshooting and Diagnostics User-Defined Loop A User-Defined Loop is similar to a Smart Jack Loop. It allows you to place remote equipment into loopback by sending a specific code to the equipment. The proper code needs to be obtained from the remote equipment’s manufacturer or operator. Several elements of the code can be defined, such as the length and value for both the activate and deactivate code. 1.
