Hey, i was wondering if anyone can help me.........is the configuration for a T1 line to a linksys wireless-n router extremely different and complicated from that of the configuration to a regular DSL/ethernet line???

i would appreciate it if anyone could give me some insight on this topic......thanks!

The real split is at the carrier handoff, not the Linksys model. As noted, the carrier determines how the circuit is presented; the Linksys WAN port expects an Ethernet‑style interface and its Internet settings are chosen according to what the ISP hands off (DHCP, static IP, or PPPoE). If the carrier presents a pure T‑carrier electrical interface, that interface must be terminated by T‑carrier termination equipment before any Ethernet router can use the circuit.

Practical checklist:

  • Identify the demarc: an RJ‑45 Ethernet handoff behaves like a DSL/cable modem; an RJ‑48C/T1 demarc is a T‑carrier. The carrier’s provisioning paperwork will say whether the link is DHCP, static, PPPoE, or a routed block.
  • For an Ethernet handoff configure the Linksys WAN per the ISP (DHCP, Static IP fields, or PPPoE credentials). Use MTU 1492 for PPPoE. Clone the WAN MAC if the ISP requires MAC registration.
  • If the carrier provides an upstream device that already does NAT, run the Linksys in AP/bridge mode or disable its DHCP/NAT to avoid double NAT; otherwise leave NAT enabled and use port forwarding/DMZ for servers.

Troubleshooting and notes:

  • Confirm physical link and sync at the demarc (carrier equipment LEDs and status). Verify the router’s WAN IP and try pinging the ISP gateway. Check router logs for PPP/Link errors.
  • T1 capacity is 1.544 Mbps symmetric; plan QoS or NAT accordingly if many clients share the link.
  • For advanced needs (multiple public IPs, BGP, or direct T1 termination) use business‑class CPE with the appropriate interface and features.

This expands on ’s remark and clarifies the Linksys settings implied in ’s question.

your T-1 Provider should be able to supply you with a Media converter so you can go from phone line to ethernet.

your T-1 Provider should be able to supply you with a Media converter so you can go from phone line to ethernet. Then you should be able to set up the router normally.

Just follow the directions.
