Nortel OM3400 (up to OC 12) or 3500 (if you need more than an OC12) series work great and are widely deployed in just about every CO I've ever been in. We use them and have had no issues. -Keith -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Erik Sundberg Sent: Thursday, October 13, 2005 1:13 PM To: nanog@merit.edu Subject: SONET MUX Hello, We are looking for a OC3 -> 3xDS3 MUX.
