Configuring The T1/PRI Board
When the factory arranges the T1/PRI board for ISDN–PRI support, it installs the DXPRI card and the
appropriate chip firmware on both boards. For field-up grade of existing T1 boards, you must install the DXPRI
card on your existing DXPT1 board and change the firmware on the DXPT1. For instructions to do this, refer to
the paragraph titled Up-Grading Your DXPT1 Board For ISDN–PRI Support, located at the end of this
publication.
Before you install a T1/PRI board in the digital communications system, determine if you must meet special
system requirements. If you do have special system requirements, use the dual in-line pin (DIP) switches provided
on the board to re-configure the T1/PRI board.
The board contains 28 DIP switches (three 8-position modules and one 4-position module). Rectangular cutouts in
the front-edge panel provide access to these switches.
The eight DIP switches nearest the bottom of the panel are accompanied by eight green LED indicators.
NOTE: These eight switches and their associated indicators are for diagnostic purposes only. The setting of these
switches does not effect the function of the T1/PRI board. The recommended setting for switches 1, 2, and
4–8 is 0 and the recommended setting of switch 3 is 1. These settings cause the green diagnostic lights to
give information about PRi layer 3 and 3 operation.
The remaining 20 DIP switches labeled SW1, SW2. and LIU are for configuring the T1/PRI board to meet
specific operating requirements. The default setting for all of these switches is 0 except for LIU–2, which you
should set to 1. This is the standard configuration for most customer applications. However, special customer
needs may require that you reset one or more of these switches using the procedure given below.
1. Obtain a static discharge wrist strap and attach it to one of your wrists. Make sure to adjust the strap for a
snug fit against your skin; do not apply the strap over any of your clothing.
2. Connect one end of the wrist strap-cord to the wrist strap and the other end to earth ground.
NOTE: With the DXP cabinet in the installed position, the ground lug on the right side of the cabinet is normally
a good grounding point since this lug should have a heavy ground wire connected between it and a good
earth ground.
3. Remove the T1/PRI board from its static protection bag and set it on a static-safe work area.
4. Using a ball-point pen or similar object, move the DIP switches from left (0 position) to right (1 position) as
needed. All DIP switches are facing left for typical applications. The paragraph titled, Setting The T1/PRI
Switches, details the DIP switch descriptions
