OM4E1PCM30 can be classified into a b c models by their respective functions. It contains its own optical interface, 4 E1, 30 channels of PCM services, 1 100Mbit/s Bas_T, and multiplexes all of them into one optical signal. Usually OM4E1PCM30 is used in point-to-point mode. OM4E1PCM30 is one equipment with reasonable price in optical network. Its front panel can be turned over and the extension cards is hot-plug. Alarm LED of each unit is visible directly for convenient monitoring.
OM4E1PCM30 contains 16 card slots totally. The right slot is MUX card slot and the other 15 slots are all extension card slots. Each signal processing slot holds 2 channels of signal. From left TS1 to right TS30, multiplexed into 1E1.
