Product SummaryRAD's IMX-2T1/E1 T1 inverse multiplexer enables E1 equipment to utilize T1 transmission facilities by converting any E1 frame received by the E1 port into two T1 frames transmitting them simultaneously over two separate T1 links. The IMX-2T1/E1 T1 inverse multiplexer enables E1 transmission in areas where rates higher than T1 are not available. The IMX-2T1/E1 T1 inverse multiplexer complies with various E1 and T1 protocols. Benefits• E1 access device for simple connectivity to international office • Bonds two T1 circuits for a maximum speed of 2.048 mbps • Full bandwidth utilization of remaining T1 timeslots for additional traffic Further Product InformationThe IMX-2T1/E1 T1 inverse multiplexer enables E1 equipment to be connected using two T1 transmission links by converting any E1 frame (2.048 Mbps) into two T1 frames (1.544 Mbps). The E1 frame (256 bits) is equally divided between both T1 frames. IMX-2T1/E1 operation is transparent to the E1 framing pattern. Optional CSUs, full bandwidth utilizationIt can be ordered with or without CSUs. Optional drop-and-insert G.703 or n x 56/64 kbps ports enable full bandwidth utilization by using the remaining T1 timeslots for additional traffic. The IMX-2T1/E1 compensates for any differential delay of up to 64 msec between the T1 lines, to properly reconstruct the original stream. The end-to-end delay is not more than the maximum differential delay between the links. Advanced diagnostic capabilitiesDiagnostic features include: • Local/remote DTE loopback • Local/remote T1 loopback • Built-in BERT In addition, the IMX-2T1/E1 supports the T1 network loopback per AT&T 62411 (in-band code activated), and statistical diagnostic capability according to AT&T PUB 54016. The IMX-2T1/E1 complies with TR-54019 (E1 Access over T1 Networks). The IMX-2T1/E1 is compatible with the DXC DIM module. Diagnostics can be initialized via the front panel or by using an ASCII terminal connected to the supervisory port.
