Chapter 2 – Installing and Cabling the MultiVOIP
MultiVOIP® Voice/Fax over IP Gateways 15
For DID channels only
For any channel on which you are using the DID interface type, you must change the jumper on the MultiVOIP
circuit card. DID is not supported on the –SS or –FX models.
1. Disconnect power. Unplug the AC power cord from the wall outlet or from the receptacle on the MultiVOIP
unit.
2. Using a #1 Phillips driver, remove the screw (at bottom of unit, near the back-cover end) that attaches the
main circuit card to the chassis of the MVP210.
3. Pull the main circuit card out about half way.
4. Identify the channels on which the DID interface is used.
5. Position the jumper for each DID channel so that it does not connect the two jumper posts. For DID
operation of a VOIP channel, the MultiVOIP works properly if you simply remove the jumper altogether, but
that is inadvisable because the jumper might be needed later if a different telephony interface is used for
that VOIP channel.
6. Slide the main circuit card back into the MultiVOIP chassis and replace the screw at the bottom of the unit.
