Unchannelized DS3 card
Connecting the unchannelized DS3 card to the WAN
Connect the T3 line to the unchannelized DS3 card with two 75-ohm coaxial cables
(RG 59/U). To provide for redundant operation, the unchannelized DS3 card has a second pair
of BNC jacks that can be used to connect to a second unchannelized DS3 card or other Data
Terminal Equipment (DTE).
When the unchannelized DS3 card is not powered or is in the reset state, the Line Rx and Line
Tx signals are electrically connected to the Bypass Rx and Bypass Tx jacks, respectively.
When the UDS3 card passes its POST, a relay switch connects the Line jacks to the card’s T3
transceiver.
Inform your service provider that the equipment is connected, so the provider can activate the
line.
Operating humidity 0-90%, noncondensing.
Operating temperature 32-104° F (0-40° C).
