MB connector SMZip is designed to replace existing connectors when switching to remote control. It is designed to connect up to 32 MB of lines and convert them to VoIP technology (voice transmission using the IP protocol in Ethernet). It also allows the connection of up to five AUT telephones and their conversion to VoIP and the connection of local analog recording for local communication recording on MB lines. An analog telephone connection is available for the functional test during commissioning, so that the system can be tested without the presence of a functional transmission system. Checking the current status of control and configuration is possible using a web browser. Current operating states and information from the internal self-diagnostics can be transferred to the superior monitoring system using the SNMP protocol and the operating history can be recorded using the SYSLOG protocol. The internal real-time clock can be synchronized using the NTP protocol.

Advantages of use  MB connectors  SMZip

• Technical equipment designed for the conversion of MB lines
  into a VoIP environment
• Allows connection of up to 32 MB of lines, or interconnection of 2 lines in the form of a through pair (line telephone)
• It enables comfortable configuration and remote control via www interface, as well as remote control and supervision using standard protocols (HTML, SNMP, NTP, SYSLOG)
• Allows you to optionally connect up to 5 AUT phones
• Enables local analog traffic recording

Basic technical description

The MB connector is built into a cabinet designed for mounting in a 19 “rack, 2U high and 35 cm deep. Weight is 6 kg.

Front panel

There are two Ethernet connectors on the front panel (one for connecting to the system, the other for connecting a service technician), as well as an indication LED showing the current status of MB lines and the connector itself and an alphanumeric LCD display showing details of the current status. There are also connectors on the front panel for connecting analog recording, service handset and auxiliary AUT lines.

Back panel

On the rear panel there is a EURO plug for connecting the 230 V power supply, a connector for the optional 48 V DC power supply connection and the connectors for the MB connection  lines. RJ45 connectors are used here – each for 4 MB lines. To connect the connector to MB lines (it is assumed to use a short cable, equipped with an RJ45 connector on one side and cut into LSA distribution strips on the other side), it is necessary to always install isolating transformers and lightning arresters on each MB line. The power supply of the connector is optional – 230 V AC or 48 V DC.
