Chapter 1 General UNIT OVERVIEW The ADTRAN T1 Channel Service Unit (CSU) Advanced Communications Equipment (ACE) provides the T1 interface between customer premises equipment (CPE) such as channel banks, T1 multiplexers, and the carrier network as shown in Figure 1. The unit complies with Part 68 of FCC Rules and with applicable sections of AT&T 62411, ANSI T1.102 and ANSI T1. 403.

General Figure 2.
Chapter 1. General POWER OPTIONS The T1 CSU ACE may receive power from a local power supply located on the customer’s premises. Local power can be supplied by the customer’s own 12 to 48 volt supply, or by the wallmount power supply shipped with the unit (see Figure 3). The wall mount power supply is an NEC class 2 device. See Powering the Unit on page 30 for details on connecting the power to the unit. Figure 3.
Chapter 1. General ALARMS The T1 CSU ACE provides five LED alarms on the front of the unit to help troubleshoot the communication channel. See Figure 4. The alarm descriptions are as follows: • The POWER LED shows that the unit is receiving power. • The SYNC LED indicates signal is present on both the Network and the Equipment interface. • NET LOS indicates loss of signal (LOS) from the network. • NET MAN LB indicates a network loopback has been activated manually from the rear panel.
Chapter 1. General LOOPBACK The T1 CSU ACE supports four types of loopbacks. With the first two, the unit loops the signal received from the network back to the network and transmits an unframed all 1s pattern to the CPE. The signal received from the CPE is ignored. The first type of loopback, Manual Network Loopback (see Table 1), is initiated by switching on the NET LB switch on the back of the unit. The NET MAN LB LED will turn On and the loopback will continue until it is switched off.
Chapter 1. General Figure 5. T1 CSU ACE Loopback Switch and LED LINE BUILD OUT The first five positions of the switch on the back of T1 CSU ACE selects Line Build Out (LBO). See Figure 6. Separate LBOs set the transmit levels for the network and CPE sides of the T1 CSU ACE. The receivers on both sides of the CSU ACE contain Automatic Line Build Out (ALBO) circuitry to compensate for loss.
Installation Chapter 2 SETTING THE LBO SWITCH POSITIONS Network and customer LBO switch position settings are defined in Table 2 and Table 3. Table 2. Network LBO Switch Position Settings POSITION 1 POSITION 2 ATTENUATION (dB) Up Up 0 Up Down 7.5 Down Up 15 Down Down 22.5 Table 3.
Chapter 2. Installation WALLMOUNTING THE UNIT The T1 CSU ACE may be installed in a wallmount or tabletop configuration. The following section provides step-by-step instructions for wallmounting the unit. Instructions for Wallmounting Step Action 1. Decide on a location for the T1 CSU ACE. Mount the unit at or below eye-level so that the LEDs are viewable. 2. Prepare the mounting surface by attaching a board (typically plywood, 3/ 4" to 1" thick) to a wall stud, using 3” wood screws.
Chapter 2. Installation Figure 7.
Chapter 2. Installation POWERING THE UNIT The unit may be powered by using the supplied NEC Class 2, 12V wall mount power supply. It may also be locally powered by own 12 to 48 V power supply. Once power has been applied to the unit, the POWER LED will be illuminated. The unit can be powered by either of the following methods: Method 1 • Use the included NEC Class 2, 12V at 800 mA wall mount power supply. Note: The wall outlet shall be near the equipment and readily accessible.
Chapter 2. Installation Notify the carrier before connecting the T1 CSU ACE to the carrier network. Connect the T1 CSU ACE to the network demarcation before connecting to the CPE. Connector pin assignments for the Net RJ48C are listed in Table 4. Connector pin assignments for the CPE 8-Pin modular jack are listed in Table 5. Table 4.
Chapter 2. Installation TEST AND MONITOR ACCESS The six Bantam jacks located on the back of the T1 CSU ACE provide test and monitor access for the network and equipment side of the T1 CSU ACE. The diagram on the face of the unit shows each jack’s function, as seen in Figure 8. Figure 8. T1 CSU ACE Bantam Jacks Monitor Jacks The first two jacks are monitor jacks used for monitoring the circuit while in service. NET MON monitors the signal received from the network.
Chapter 2. Installation Break-and-Test Jacks The other four jacks are break-and-test jacks used for out-of-service testing. These jacks bypass the connections of the modular jacks. NET IN and NET OUT are used to simulate the network input and output of the T1 CSU ACE. To test the CPE, a T1 Bit Error Rate Test (BERT) test set can be used to simulate the network.

Chapter 3 Troubleshooting and Maintenance Troubleshooting guidelines and maintenance information are provided in this chapter. TROUBLESHOOTING Power Condition: PWR LED is not illuminated. 1. If locally powered, verify the power cable installation. 2. If the 12 V wall-mount power supply is used, check the supply’s cable and the circuit breaker for the 120 V receptacle the supply is plugged into. Network LOS Condition: NET LOS LED is illuminated. 1.
Chapter 3. Troubleshooting and Maintenance Equipment LOS Condition: EQ LOS LED is illuminated. 1. Verify that the cable from the CPE is in the CPE modular jack on the bottom/end of the CSU ACE. 2. If all connections seem intact, use a BERT test set in the NET IN and NET OUT jacks to test the CPE. Power On - Self Check Failure Condition: NET LOS, EQ LOS, NET LB, and EQ LB all flash in unison, continuously. • The unit has failed its internal self check.
