1. Summary
Our ZMUX-1215 is a digital channel protection switching device. It can switch transmissions from main to stand-by channels after receiving manual switching commands when power failure occurs on the main channels.
Our ZMUX-1215 is a digital channel protection switching device. It can switch transmissions from main to stand-by channels after receiving manual switching commands when power failure occurs on the main channels.
2. Function Features
1)Mandatory switching from main to stand-by channels by device switchgear or by software to protect 15 digital channels;
2)One of the communication types (by Ethernet, RS232 or RS485) can be chosen for software-controlled switching;
3)When software-controlled switching is chosen,the number and quantity of switched channels can be set by pc;
4)Supporting cascading of 256 ports of RS485;
5)One device supports 15 E1 channels, and total amount of cascaded devices is up to 256, so the total capacity is 3840 E1 channels.

5. Implication of indicators on the panel
LED name | The implication of indicators | Colors | Notes |
RUN | It is twinking when the device is powered on. | green | The device is powered on |
LINK | It is lighted when supervision is made by Ethernet interface. | green | |
MASTER | It is lighted when switching to main channel in mandatory mode. | green | |
SLAVE | It is lighted when switching to stand-by channel in mandatory mode. | green | |
TX | It is twinkling when supervision is made on transmited data. | green | |
RX | It is twinkling when supervision is made on received data. | green | |
1-30 | The indicators of corresponding channels are OFF when main channels are switched. The indicators of corresponding channels are OFF when stand-by channels are switched. | green | The subscriber indicators will twinkle once when self test is made on the power-on device. Among which, indicators 1 & 2 corresponds to 1st E1 channel,indicators 3 & 4 corresponds to 2st E1 channel, et cetera, totally 15 corresponding E1 channels. |
6. Scope of Application
This device is suitable for protecting important data transmission channels for business tranmissions of graphic imaging co,banks,exchanges, it is also suitable for specific netwwork accesses with important E1 transmissions,such as national defense,government and organzation, customs house, public security department and power companies,etc.
