The IDM MAP64 Integrated Service Multiplexer adopts a 19-inch 2U standard chassis, implementing non-blocking full cross-connect multiplexing of 64 channels of 64K services over 8 groups of E1. It features a pluggable structure for convenient maintenance and management.

The entire unit can be configured with:
1 E1 Central Management Unit (CMU) card (mandatory), 8 voice cards (FXO/FXS), and a DC power card or AC power card. The CMU card provides 8 groups of E1 interfaces and manages/controls the E1 interfaces and USER cards. Either the DC power card or AC power card can be selected, or dual power supply (DC and AC) can be configured. Each voice card provides 8 user interfaces, and the transmit/receive gain of each voice channel can be adjusted externally on the user card front panel, supporting hot-swap. Unified network management across the entire network is supported, with both serial and Ethernet network management interfaces available.
