GENERAL This practice provides installation and maintenance information for the ADTRAN® Intelligent 2-Wire Foreign Exchange Station/Dial Pulse Originate (2FXS/DPO PM) Dataport with Performance Monitoring, part number 1109403L2. It is a D4 compatible channel unit and operates in any standard D4 channel bank. Intelligent features requires the unit to be used in the ADTRAN ACT 2300, ACT 1900 , or standard WECO® D4 channel bank using the ADTRAN LIU-3/PM common unit. The 2FXS/ DPO PM provides an interface between a D4 channel bank Pulse Code Modulation (PCM) backplane interface and a 2-wire voice frequency (VF) transmission and signaling facility. Figure 1 is an illustration of the 2FXS/ DPO PM. The unit is multifunctional and can be provisioned to operate in the following modes: • 2-Wire Foreign Exchange Station (2FXS) • Dial Pulse Originate (DPO) • Tandem FXS Mode • Private Line Auto Ringdown (PLAR) Figure 1. 2FXS/DPO 2FXS/DPO1109403L2PM AP REM PM TEST BUSY SW 4 SW 3 SW 2 SW 1 SW 7 Using the FXS/DPO PM in an intelligent channel bank provides additional features and functions such as: • Local and Remote Provisioning using either the craft interface or ADTRAN Site Manager through a menu driven program called EASYMENU™ • Performance monitoring of the loop • Network and customer side monitoring and analysis • Enhanced Test Capabilities Revision History Revisions to this practice include CLEI code and dip switch settings. Features • Backplane interface to the Pulse Code Modulation (PCM) bus. • On board coder/decoder (CODEC) uses m-law encoding/decoding. • Nominal 600 ohm or 900 ohm 2-Wire VF interface with DC isolation.

INSTALLATION After unpacking the unit, immediately inspect it for possible shipping damage. If damage is discovered, file a claim immediately with the carrier and then contact ADTRAN customer service (seesection 6, Warranty and Customer Service). The 2FXS/DPO PM plugs directly into an ADTRAN ACT 2300/1900 or standard D4 channel bank. No installation wiring is required. To install, grasp the 2FXS/DPO PM by the faceplate and insert it into the backplane connector until firmly seated. Provisioning Options Most options on the 2FXS/DPO are provisionable either manually, using internal slide switches, or electronically using a menu-driven program called EASYMENU. The trunk processing options are found on internal slide Switch 7 (SW7) and can only be provisioned manually. Manual provisioning should be completed before the 2FXS/DPO is inserted into the channel bank. Electronic provisioning should be completed following installation. Manual Provisioning Internal slide switches SW1,2, 3, 4, and SW7 are used to manually provision and set the operational modes and options of the unit. Figure 1 displays switch locations. Slide switches SW1 and SW2 are used to set, receive, and transmit attenuation. Table Adisplays the available options. Slide switches SW3-1, 2, 3, 4, and SW3-5 are used to provision the desired operation mode of the unit. Slide switch SW4 is used to provision the trunk processing (SD), dial pulse correction (DPC), loop or ground start (GS), PLAR mode (PD3), tandem battery mode (TRB), tandem start mode (TWS), dial tone (DTG), and ringback tone (RTG).
