2. 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 (see section 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
Manualprovisioningshouldbecompletedbefore 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 transmitattenuation. Table A displaystheavailableoptions.
Slide switches
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).
Slide switch SW7 is used to provision the trunk processing options: make busy lead (1G), make busy closure (L), and busy trunk sleeve (S). Table B summarizes the option settings for SW3, SW4, and SW7.
