The ML-8E1 and ML-8T1 modules enable direct connection of Megaplex to up to 8 E1 or T1 lines. Up to 12 modules can be installed in a single chassis, providing Megaplex with up to 96 E1/T1 ports.
The E1 interface is compatible with all carrier-provided E1 services, meeting the requirements of ITU-T Rec. G.703, G.704 and G.732. It supports both 2 (G732N) and 16 (G732N) frames per multiframe. CRC-4 and E bit are also supported, complying with G.704 recommendations. Zero suppression over the lines is HDB3.
The E1 interface is equipped with an integral user-enabled LTU, ensuring ranges of up to 2 km (1.2 miles).
The T1 interface is compatible with ANSI requirements. Both D4 and ESF framing formats are supported. Zero suppression is selectable for Transparent, B7ZS, or B8ZS.
The T1 interface is equipped with an integral user-enabled CSU, ensuring ranges of up to 1.6 km (1 mile).
Diagnostic capabilities feature local and remote loopbacks on each port, and local and remote loopbacks per timeslot.
