Intelligent 1U4E1PCM30 has 4 E1 ports, 30 signal channels. With 128X128 time slot cross-connections, it distributes 30 channels of speech signal converted into 4 E1 channels. 1U4E1PCM30 is a multi-functional equipment for small volume of information processing. Its front panel can be turned over and the expansion cards is hot-plug. Alarm LED of each unit is visible directly for convenient checking. 1U4E1PCM30 is compatible with other HG PCM products.
1U4E1PCM30 has two V24(RS232) ports and can be extended upto four ports by the customers’ requirements.
With network supervision software, the four E1 ports can be automatically switched. If an error occurs at one E1 port, another port can take part of the mal-functional one automatically.
1U4E1PCM30 has 16 card slots. The right slot is MUX card slot and the other 15 slots are all extension card slots. Each signal processing slot holds two channels of signal
