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 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 A displays 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).
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.
