 The EM316T1 E-1 Fiber modems and the EM316E1 T-1 Fiber modems modules 
            of the Fiber DriverT family are designed to extend the distance and 
            transmission reliability of T1 Fiber modems (1.544Mbps) or E1 fiber 
            modems (2.048Mbps) traffic. These units convert the electrical signals 
            to optical signals and transmit them over distances of up to 10 km 
            on Multimode fiber, or distances of up to 100 km on Singlemode fiber.
 
 The EM316T1 and EM316E1 are transparent to the framing format, and 
            support AMI or B8ZS (T1) and HDB3 (E1) line codes, respectively. They 
            include an internal elastic buffer to remove jitter from the transmitted 
            data.
 
 Six LED indicators aid in monitoring and trouble-shooting this module. 
            A management agent is incorporated on the module to enable management 
            in conjunction with the Fiber Driver EM316NM management card.
 
 As part of the Fiber Driver family, the EM316T1 and EM316E1 modules 
            fit in all Fiber Driver chassis types, support local and remote loopback 
            tests, and can be used to interconnect between any T1 or E1 devices. 
            Among the types of T1/E1 devices that can be connected by these modules 
            are PBXs, multiplexers, video CODECS, routers, network servers, and 
            ATM/frame relay switches.
 
 Benefits include extended distances, improved quality of transmission, 
            better security, remote management capability, and high density.
