Description

The %%multiplexer%% is designed in 19” 1U compact case. It includes 4 Ethernet 10/100 ports, 4 E1 ports, 4 RS232 ports.

The multiplexer enables linking up peripheral devices with serial RS232 interfaces to networks built using SDH/PDH through E1 interfaces, each capable of transmitting both full-size and divided streams.

The administration of SG-17R/MR-17G4/2xMR-17S2T (4xE1, 4xRS232, 4xEth10/100) may be competed through serial interface, SNMP, Web, ssh. The device features options of remote program update, configuration saving and restoring.

The SG-17R/MR-17G4/2xMR-17S2T (4xE1, 4xRS232, 4xEth10/100) multiplexer may be used both in business and carrier networks. By means of the multiplexer it is possible to establish console control over the equipment, for example base stations, PBXs, or set up a automatic control system, namely, to link up controllers to the dispatching station over private network.

If needed, the SG-17R/MR-17G4/2xMR-17S2T (4xE1, 4xRS232, 4xEth10/100) equipment may simultaneously be a multiplexer and a router for different interfaces. 

When used as a router, DHCP и DNS settings may be used; traffic management is carried out by means of NAT, Firewall, QoS. The device allows using static paths and itself may be using RIP protocol. If there is no need and the router-mode is off, the device may function as a bridge in the mode of direct-connection between the chosen interfaces.

By means of a built-in 4-port Ethernet 10/100 commutator it is possible to unite a small local group, with the possibility for each of the ports to be configured individually according to the traffic-control rules. Each of the ports may as well function as a LAN or WAN interface. Port-based and port-tagged VLAN is supported.

The SG-17R-1RU-CP2-3SFP/220VAC-W1 variant of the base platform may be used to link to high-speed gigabit trunks.

Each of the channels of the E1 module may be used in the multiplexing mode into SHDSL, RS232 and other E1 channels or for routing the data in HDLC mode.

Setting up additional SHDSL module enables transmitting the data between remote objects over dedicated line. This channel may be used for both IP traffic transmission and E1 streams multiplexing. The maximum rate in the line reaches 14080 kbit/s, which enables transmitting up to 6 E1 channels over single pair. In the multiplexing mode when using multi-pair link the surplus from E1 streams is aggregated in a single logical channel for further Ethernet transport. The “remote power supplier” mode allows using these devices together with SG-17E regenerators for maintaining the required rate on the line or for increasing the distance between SHDSL devices. The SG-17R/MR-17G4/2xMR-17S2T (4xE1, 4xRS232, 4xEth10/100) multiplexer features built-in option of circuit monitoring in accordance with the G.991.2 standard. The multiplexer supports MIB-II and HDSL2-SHDSL-LINE-MIB.

Additional telephone modules FXO/FXS/VF allow linking up subscriber lines form BPXs, telephones, fax machines and voice-frequency channels equipment. The SG-17R base platform allows installing all these modules in different combinations.

Adapter-module for CardBus Card allows using standard devices of this class, for example, to establish a Wi-Fi connection. In this case the device may be either access point or the client.

For multipurpose traffic transmission over the chosen interface there are two modes available:  data-multiplexing mode and packet-mode with isolated fixed pass-band and QoS for the requested service.
