These are broadband, cablemodem point-to-point type. I have a couple of them that need to be fixed but the company seems to be disapeared. I would really appreciate if you know a lab or where can I send these for repair. Please contact me off-list, I don't want to increase noise. Thanks in advance. -- Miguel Mata-Cardona Intercom El Salvador mmata@intercom.com.sv voz: ++(503) 278-5068 fax: ++(503) 265-7024
