MB multiline set SMZip has been designed for replacement of current multiline subscribers during transition to the remote control. It is designed to connect of up to 32 MB lines and their transfer to VoIP technology (voice transmission by IP protocol in the Ethernet network). In addition it allows coupling of up to five AUT telephones and their transfer into VoIP and connecting the local analogue recording for local communication recording on MB lines. In order to test the system without the presence of functional transmission system, an analogue phone is available for the function test during putting the system into operation. Detection of the current state of control and configuration is possible via Ethernet interface with web browser. Current operating conditions and information from the inner auto-diagnostics can be transferred to superior surveillance system using SNMP and SYSLOG protocol by recording the operating history. The internal real time clock can be synchronized using NTP protocol.
The main advantages of MB multiline set SMZIP
- Technical equipment designed for transfer of MB lines to VoIP environment
- Allows connecting of up to 32 MB lines,or mutual interconnection of 2 lines into the form of the transit pair (line telephone)
- Enables user friendly configuration and remote control over www interface, in addition the remote control and supervision by standard protocols (HTML, SNMP, NTP, SYSLOG)pomocí standardních protokolů (HTML, SNMP, NTP, SYSLOG)
- Allows optionally to connect up to 5 AUT phones
- Allows local analogue recording of the operation
Basic technical description
MB multiline set is built in the cabinet designed for installation into 19“ rack, height of 2U and depth of 35 cm. Weight is 6 kg.
On the front panel are located two Ethernet connectors (one for connecting to the system, the second for the service technician), the LED indicator showing the current state of MB lines, the MB multi line subscriber set and the alphanumeric LCD display showing details of the current state. Furthermore, the front panel includes connectors for analogue recording, service headphone and auxiliary service AUT lines.
On the rear panel is located the EURO plug for 230 V power connection, connector for optional connection of 48 V DC power supply and connectors to connect MB lines. Here the RJ45 connectors – each for 4 MB lines are used. For connecting the multiline set to MB lines (it is assumed to use a short cable fitted on one side with RJ45 connector and on the other side cut into the LSA distribution bars) it is necessary that they are always fitted with isolation transformers and lighting arresters on each MB line. The power supply of the Multiline Set is optional 230 V AC or 48 V DC.
