Description

The IMX-2T1/E1 enables E1 equipment to utilize 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 is transparent to the E1 framing pattern. It 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.

Diagnostic features include:
- local/remote DTE loopback
- local/remote T1 loopback
- built-in BERT V.52

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-M/DIM module.

Diagnostics can be initialized via the front panel or by using an ASCII terminal connected to the supervisory port.
