For an E&M connection.
(E&M Example: trunk line from telephone switch.)
Connect one end of an RJ-45 phone cord to the Channel 1 E&M
connector on the back of the MultiVOIP.
Connect the other end to the trunk line.
Verify that the E&M Type in the E&M Options group of the Interface
dialog box is the same as the E&M trunk type supported by the
telephone switch. See Appendix B for an E&M cabling pinout.
For a DID connection.
(DID Example: DID fax system or DID voice phone lines.)
Connect one end of an RJ-11 phone cord to the Channel 1 FXS/FXO
connector on the back of the MultiVOIP.
Connect the other end to the DID jack.
NOTE : DID lines are polarity sensitive. If, during testing, the DID line
rings busy consistently, you will need to reverse the polarity of
one end of the connector (swap the connections of the wires to
the two middle pins of one RJ-11 connector).
6. Repeat the above step to connect the remaining telephone equipment
to the second channel on your MultiVOIP.
7. Ensure that the unit is properly connected to earth ground by
verifying that it is reliably grounded when mounted within a rack.
This can be accomplished by connecting a grounding wire between
the chassis and a metallic object that will provide an electrical
ground.
8. Turn on power to the MultiVOIP by placing the ON/OFF switch on
the back panel to the ON position. Wait for the BOOT LED on the
MultiVOIP to go off before proceeding. This may take a few minutes.
Proceed to the Software Installation chapter to load the MultiVOIP
software.
