The M16E1 and M16T1 modules enable direct connection of Megaplex-4 to up to 16 E1 or T1 lines. Up to 10 modules can be installed in a single Megaplex-4100 chassis, providing it with up to 160 E1/T1 ports. The compact Megaplex-4104 chassis accommodates up to 4 modules, providing up to 64 E1/T1 ports.
The M16E1, M16T1 modules have 16 independently configurable E1/T1 external 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 operates in both 2 (G732N) and 16 (G732S) frames per multiframe formats, as well as in unframed mode. CRC-4 and Ebit are also supported, complying with G.704 recommendations. Zero suppression over the line is HDB3.
The T1 interface is compatible with ANSI requirements. Both D4 and ESF framing formats are supported. Zero suppression is selectable for Transparent, B7, or B8ZS.
Diagnostic capabilities include local and remote loopbacks and BER test on the E1/T1 ports and inband code-activated loopbacks specified in ANSI T1E1.2/93-003 (T1 interface only). Performance statistics for the E1/T1 ports may be obtained and analyzed via the Megaplex management system.
