I guess it is the right impedance, but I've never seen it used in a telco facility. The bulk cable we use for short DS3 cross connects is much thinner stuff and easier to work with, while what the telco uses to go between floors in the CO is thick and very stiff cable. I think it's 735 and 734, but it's been a while since I've personally terminated any DS3s. According to some docs from ADC, RG59 (used for DS3) has a maximum cable run length roughly half way between those of 735 and 734. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
