Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice Description The T1-OR/NIU enhances existing T1 repeater spans. The T1-OR/NIU provides troubleshooting capabilities through either locally or remotely-programmed options and loopbacks. The T1-OR/NIU receive-transmission-path provides a long-haul regenerator, followed by a provisionable DSX pre-equalizer, and its transmit path provides a short-haul regenerator followed by a provisionable transmit line build-out.
Installation This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by ADTRAN could void the user’s authority to operate this equipment. INSTALLATION After unpacking the T1-OR/NIU, inspect it for damage.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice Instructions for Installing the Module To install the Total Access 3000/3010 T1-OR/NIU, perform the following steps: 1. Set the Span Power option to either T1-OR or NIU. Two board-mounted jumper straps (P4) select this span power option. a. Set Span Power option to T1-OR. Move P4 straps to posts 1-3 and 2-4 (default setting).
Installation Front Panel LEDs The T1-OR/NIU provides front panel LEDs to display status information. Table 2 shows the LEDs and status descriptions. Table 2.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice FRONT PANEL OPERATION The T1-OR/NIU provides the following front panel operational controls: • LBK pushbutton XMT and RCV span power test points • DSX TX and RX monitor (MON) jacks • DSX TX and RX equalizer (EQ) jacks LBK Pushbutton The LBK push button initiates a loopback to the network and sends an AIS signal (all ones) toward the customer end. LBK Operation • To activate a loopback, depress the LBK pushbutton for two seconds.
Front Panel Operation Front Panel Bantam Jacks Monitoring of DSX signal characteristics can be performed through two sets of front panel bantam jacks. Table 4 describes the functions of the jacks and test points. Bantam EQ and MON test jacks provide two monitoring functions depending on the mode of the module: • Office Repeater (OR) • Network Interface Unit (NIU) NOTE EQ Jacks do not function in NIU mode if the customer equipment is connected to the DSX interface. CAUTION EQ testing is intrusive.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice CONNECTIONS The cabling for the T1-OR/NIU is significantly different for each mode of operation: • “Office Repeater Mode” on page 8 • “Network Interface Unit Mode” on page 9 Office Repeater Mode Figure 2 illustrates the Office Repeater mode.

Appendix A Front Panel DSX and MUX Mode Test Access GENERAL Figure A-1 through Figure A-3 are DSX-1 fed modes of operation, and Figure A-4 through Figure A-7 are MUX fed modes of operation. From the Provisioning menu (“Provisioning” on page 17), the Network Source option is used to choose either MUX fed or DSX fed operation. When performing intrusive MUX mode testing, the equipment jack on the front panel can be configured to access the signal going to the network or the customer.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice DSX MON, Tx to Customer The Rx of the BERT receives data from the TX MON jack (Figure A-1). This data has a monitor jack impedance of 432 ohms and comes from the Backplane Network T1 DSX (the data that would go toward the customer). The BERT TX jack is not used. This test is non-intrusive. NOTE Provision the T1-OR/NIU for the Out-of-Service Maintenance service state when performing intrusive bantam jack testing.
Appendix A, Front Panel DSX and MUX Mode Test Access - DSX Mode Test Access DSX MON, Rx from Customer The Rx of the BERT receives data from the RX MON jack (Figure A-2). This data has a monitor jack impedance of 432 ohms and comes from the customer-originated data. The BERT TX jack is not used. This test is non-intrusive.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice MUX MODE TEST ACCESS MUX Mode tests through a MUX on the Total Access 3000 shelf. MUX MON, Tx to Customer The Rx of the BERT receives data from the TX MON EQ jack (Figure A-4). This data is a copy of the data that the T1-OR/NIU will transmit to the customer. The Tx of the BERT is not used. This test is non-intrusive.
Appendix A, Front Panel DSX and MUX Mode Test Access - MUX Mode Test Access MUX EQ, Tx to Network, Rx from the Network The Tx of the BERT is connected to the EQ TX jack, and the Rx of the BERT is connected to the RX EQ jack (Figure A-6). The Tx of the BERT is then substituted for the data that the T1-OR/ NIU sends to the Total Access Shelf MUX (network). The Rx of the BERT receives data directly from the MUX (network). The MON TX and RX jacks are 432 ohm impedance copies of the EQ jack TX and RX.
Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice MUX EQ, Tx to Customer, Rx from Customer The Tx of the BERT is connected to the EQ TX jack, and the Rx of the BERT is connected to the RX EQ jack (Figure A-7). The Tx of the BERT is then substituted for the data that the T1-OR/ NIU sends to the customer. The Rx of the BERT receives data directly from the customer. The MON TX and RX jacks are 432 ohm impedance copies of the EQ jack TX and RX. This test is intrusive.
