Modem Eliminator
The UDC-ME X.21 modem eliminator allows two DTE devices (such as routers) to communicate within proximity of each other. The UDC-ME transmits data bidirectionally at clock rates of 1.2k up to 3.072Mbps between DTE devices. All clocking and signal crossover are provided within the UDC-ME. The unit is equipped with two interface slots that allow a host of serial interface cards to be utilized. The serial interface cards available are RS-232, RS-422/449, RS-530, X.21, V.35 and HSSI. The Serial Interface cards are interchangeable and may be mixed such as RS-232 to V.35 thus eliminating the need for an interface converter or changing expensive serial cards on a DTE device such as a router.
The UDC-ME X.21 modem eliminator is also an excellent choice for testing router-to-router connections via the serial ports. The unit is an excellent choice for interconnecting your LAN or legacy mainframe equipment.
Installation is fast and simple by setting the internal switches for Clocking, Carrier Operation and RTS to CTS delay. The UDC-ME has status LED’s for each attached DTE device which allows the user to visually confirm the presence of clock and control signals. The UDC-ME utilizes state of the art digital CMOS technology to provide a feature filled product at a very affordable price. Our Field Programmable Gate Array (FPGA) design has allowed us to offer this product with a wide selection of clock rates. This design approach has also reduced the amount of clock jitter for high speed transmissions.
The UDC-ME is housed in a sturdy metal enclosure and operates on 110/220VAC or optional -48V DC power. Typical MTBF figures are in excess of 150,000 hours of operation.
The UDC-ME has a three year warranty and a 24 hour turnaround on warranty repairs.
