Station modem SM-4X4E-02C
Descriptions
SM-4X4E-02C is designed to transmit 4 E1 streams over coaxial cables with a wave impedance of 75 Ohms.
The device has 4 E1 ports and 4 SHDSL ports. Data received by E1 ports can be transmitted via one, two, three or all four SHDSL ports depending on the settings and equipment configuration.
The station modem supports line operation in the combined transreceiving (CTR) and individual transreceiving (ITR) modes. ITR allows the device to operate on one cable line with outdated analog equipment, without having a significant electromagnetic effect on it.
The device has a number of diagnostic feature, such as the installation of engineering loops, latching errors and alarm conditions.
SM-4X4E-02C is controlled and monitored using dedicated software “Stream-2” v3.0 or higher.
The device is designed for operation within station equipment set “Stream-2”. Design - 19” built-in module, for installation in UES-6141.
Scopes
- Organizing high-speed trunk communication channels;
- Operation in one cable with analog equipment;
- Integrated regenerator monitoring channel;
- PC control and diagnostics;
- Easy maintenance;
- Integrated input circuit protection.
