Planning the Installation of a “POTS” Modem
To install a USB “POTS” modem, you will typically need the following:
1. [__] The modem itself;
2. [__] The modem's documentation and drivers CD, in case you need to install the modem on a PC to verify proper
operation;
3. [__] RJ11 telephone cord of sufficient length;
4. [__] USB extension cable if the modem cannot be plugged directly into the AcquiSuite/AcquiLite DAS's USB port.
Note that all of the USB “POTS” modems have USB “type-A” male plugs, so the necessary extension cable would
be a USB “type-A” male to “type-A” female.
5. [__] A PC (or other device with a full-featured web browser) to be used to configure the modem via the
AcquiSuite/AcquiLite DAS's web user-interface.
6. [__] An Ethernet cross-over cable to connect said PC to the DAS's ethernet port.
7. If the DAS is going to be dialing out, you'll need:
1. [__] The telephone number of the PPP server the DAS will be dialing into;
2. [__] Any special dial-prefixes to get an outside line (e.g., “dial 9”);
3. [__] The PPP username and PPP password the DAS will use to log into the PPP server.
8. If the DAS will be receiving dial-in calls, you'll need:
1. [__] The contact information of the person who can trigger such a dial-in call while you are at the site, to allow
testing of the dial-in configuration;
2. [__] The phone number assigned to the telephone line the DAS will use to receive calls, in case you need the
assistance of Obvius Tech Support.
