Ready to begin?
It is easy and with every step, you are closer to experiencing the speed and convenience of Big Bend Broadband.
1) First make sure you received all equipment necessary for installation from Big Bend Telephone. Inventory checklist:
- Big Bend Broadband Set-up CD
- DSL Modem
- DSL Modem AC adapter
- Tripp Lite Travel Cube surge protector
- RJ11-A cable (orange label)
- RJ11-B cable (yellow label)
- Ethernet cable RJ-45 (green label)
- DSL filter (red label)
2) Insert the Big Bend Broadband Set-up CD into the CD-Rom drive of your computer and follow the on-screen instructions. Macintosh users can find detailed instructions in the self-help Macintosh folder on the Big Bend Broadband Set-up CD.
3) Place DSL filters (red label) on all telecommunications devices (telephones, fax machines, alarms, satellite receivers, etc.) that share the same phone number with your DSL line and are not connected directly to the DSL modem (Figure 3).
4) Plug the Tripp Lite Travel Cube surge protector into a grounded, three- conductor, 120VAC outlet (Figure 1). Do not plug into two-wire cords or adapters. The Travel Cube is for protecting the DSL modem only. Do not plug any other type of equipment into this Travel Cube.
5) Connect one end of the RJ11-A cable (orange label) into the “IN” jack of the Travel Cube and the other end of the cable into the DSL wall jack. Make sure there is no DSL filter on this line.
6) Connect one end of the RJ11-B cable (yellow label) into the “OUT” jack of the Travel Cube and the other end of the cable into the DSL modem “LINE” jack. Make sure there is no DSL filter on this line.
7) Attach the DSL modem AC adapter to the DSL modem and the Tripp Lite Travel Cube surge protector.
8) Connect your computer to a LAN port on the DSL modem using the Ethernet cable RJ-45 (green label); you may also connect other computers, hubs, switches, and wireless access points to the LAN ports (Figure 2).
9) You may choose to connect a telephone to the “PHONE” jack of the DSL modem. This will not affect your Big Bend Broadband service. Make sure there is no DSL filter installed on this line.
All equipment noted in red is supplied by Big Bend Telephone. Please ensure you received all items in your Welcome and Installation box.
