It includes 48 Vdc power supply, complete alarm functions, one RS232 asynchronous interface, and remote loop back functions.

Transition Networks, Inc.    Minneapolis, MN 55344
Jan 27, 2005 Suited for point-to-point implementations, Transport MUX can transport multiple T1/E1 lines, 10/100 Ethernet, and RS232 Data Channel over single pair of fiber or single fiber strand. It provides copper connections compatible with G.703, AMI/B8ZS/HDB3, 10/100BASE-TX, as well as RS232 channel; while optical channel will run at 155 Mbps. If fault condition occurs, Automatic Link Restoration ensures that no user intervention is required to bring link back up again.

Metrobility Optical Systems    Merrimack, NH 03054
Mar 09, 2004 Combining T1/E1 single-strand, bi-directional wavelength (BWDM) multiplexer with Ethernet BWDM allows TDM voice and high-speed data traffic to co-exist on fiber pair, without intermixing traffic types. Where fiber is installed between buildings, system can eliminate point-to-point T1 or E1 lines for each location by creating single, private, voice/data network. Optical transmission is immune to EMI emissions.
