Overview
The IDM OMP3500 Integrated Service Access Equipment is a comprehensive multiplexing platform that can transmit up to 16 groups of transparent E1, 2 groups of physically isolated line-rate Gigabit Ethernet, 4 groups of line-rate physically isolated 100M Ethernet, and 30 channels of narrowband PCM over 2.5G optical fiber. It provides 2 groups of 2.5G optical fiber mutual backup.
PCM narrowband services provide various user interfaces such as voice, data, and image. It also has a non-blocking cross-connect device for timeslots between 2 groups of E1 and all user interfaces. The device supports multiple clock modes to meet clock requirements in various application environments.
It can simultaneously provide ~220V and -48V power supply.
