Lines: 10 Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 11, Issue 195, Message 9 of 12 Re use of 50 conductor telephone cable for LAN- Starlan-10 (10base-t) was designed specifically for this type of cabling, in order to use existing telephone wiring for data communication. As its name implies, the connections are in a star configuration, with a repeater at the center of the star. It expects to see approx. 100 ohm impedance on the cable, and does not normally interfere with voice traffic because of the frequency difference (5-10 MHz vs. 3 kHz).
