E&M Jumper Block Positioning Procedure - Multitech MVP200 User Giude

E&M Jumper Block Positioning Procedure
Each voice/fax channel on the MultiVOIP has a separate E&M jumper block, located near the jacks
on the back panel of the MultiVOIP. Each jumper block has 8 pairs of pins with a jumper plug on
three adjacent pairs of pins. The jumper plug must be centered on the E&M type number (see Figure
2-3) that matches the E&M connection for that channel.
MultiVOIP 200's shipped to Europe, Great Britain, and Ireland have the default setting for the E&M
jumper blocks defaulted to a type 5.
Perform the following procedure if you need to move the E&M jumper block from its default (Type 2)
position.
1. Ensure that the external power supply is disconnected from the MultiVOIP.
2. Turn the MultiVOIP upside down and remove the cabinet mounting screw at the center back
of the cabinet.
3. Turn the MultiVOIP right side up, then slide the base out the rear of the cabinet.
Note: To change a jumper position, lift the jumper plug up off the jumper block, then move it
to the new position, ensuring that the middle jumper of the jumper block is centered on the
E&M type number (1, 3, 4, or 5) as shown on Figure 2-3. Numbers are not on the board.

4. Change the jumper block position for any voice/fax channel to be connected to an E&M trunk
that is not a Type 2 (the default position).
5. Slide the base all the way into the cabinet until it stops.
6. Turn the MultiVOIP upside down and replace the cabinet mounting screw that was removed
in step 2.
7. Turn the MultiVOIP right side up, then perform the cabling procedure.
