Description

Functions

The SG-17R-1RU-CP1-4ETH/DC base platform modular platform is designed to operate as a router, multiplexer, bridge, DSLAM, access server, IP-gateway, IT-PBX, most of the functions being carried out simultaneously by the same device.

BridgeThe bridge mode enables the device to carry out transparent traffic transmission between its interfaces. For example, it is possible to transmit traffic transparently between two Ethernet networks over an SHDSL consisting of several channels.

Multiplexer
The multiplexer mode enables transmission of data streams by means of IP and TDM technologies, over the chosen broad-band interface (SHDSL, Ethernet, E1). Both E1 and RS232 interfaces may be used as narrow-band (low-speed) channels. In this case, additional router or bridge setup completed, the remaining band may be used for Ethernet traffic transmission. To transmit E1 streams over Ethernet by TDMoIP, SG-17R platform with a stronger processor module is used. Both copper medium 10/100/1000 Mbit/s and optical channel linked over plug-in SFP interface may be used as Ethernet.

Router
The router mode enables transmission of traffic among different IP-networks, linked to different interfaces, routing rules observed. Both static and dynamic routing is supported.

DSLAM
The DSLAM mode transforms SG-17R-1RU-CP1-4ETH/DC base platform into commutator that transmits data between SHDSL or Ethernet network interfaces. The SHDSL and Ethernet modules, being parts of the device, are capable of power-feeding the link.

Access server
The access server mode provides control over equipment linked to SG-17R-1RU-CP1-4ETH/DC base platform over RS232.

IP-gateway
The IP-gateway mode allows both separating and uniting telephones using VoIP and data transmission over Ethernet, SHDSL and E1.

IP-PBX

The IP-PBX mode allows setting up miniPBX, which, in its turn enables calls over SIP-server, calls between ports within single device or among different SG-17R-1RU-CP1-4ETH/DC base platform devices. The miniPBX enables automatic call-forwarding between FXS/FXO ports.

Software:

The software of the SG-17R-1RU-CP1-4ETH/DC base platform platform is Linux OS freeware. The platform is controlled through web-interface (Russian and English); troubleshooting is completed over serial port or over SSH protocol. The platform software is updated via TFTP server.

Data transmission

SG-17R-1RU-CP1-4ETH/DC base platform supports “bonding” mechanism or PPP-Multilink protocol both of which enable uniting SHDSL, E1, RS232 interfaces for further increasing the carrying capacity and improving reliability. When using “bonding”, the channel capacity remains unchanged irrespective of integrity of the pairs, over which data is transmitted. Furthermore, transmission rate may be set taking into account the maximum carrying capacity of the channels.
SG-17R-1RU-CP1-4ETH/DC base platform may operate as firewall, rejecting or accessing packets on the basis of the protocol, source and destination addresses and No. of the ports used. By means of NAT address translation applicable to SNAT or DNAT is completed.

QoS enables prioritizing packets. QoS is supported by various class and classless disciplines. There is an option of singling out fixed bands for different types of traffic or for different networks.

VLAN support helps to isolate traffic transmitted through the same physical medium. The port may be set up so as to transmit either entire traffic or single packets with certain LAN numbers.
SG-17R enables crating tunnels for tamper-free data exchange.

Hardware

Built-in Ethernet ports may be set up as commutators, i.e. may transmit data by-passing the processer. These ports operate as a single network interface in the system. Interdependence of the interfaces may be set, in which case, for instance, if the link on SHDSL fails, the link of the corresponding Ethernet or E1 interface turns down as well.

Services

SG-17R features built-in DHCP and DNS servers. DHCP server allows assigning IP addresses to PCs in the networks it runs in. DNS server helps transfer requests to higher-level DNS-servers or locate DNS zones directly on the device.

Monitoring

SG-17R enables receiving multiple parameters of SHDSL channel (signal to noise ratio, number of errors, etc) through separate EOC control channel. This information is available via web-interface or via SNMP (HDSL2-SHDSL-LINE-MIB).

Basic information on the system in accordance with MIB-2 is also available via SNMP: information about network interfaces, routing tables, processor load, etc.

Generation of NetFlow (v.1, 5, 7) may be set up for collection of statistic on the volume of traffic.

Usage examples

Uniting Ethernet networks over several pairs using different interfaces: SHDSL, E1, RS232

Объединение Ethernet сетей по нескольким парам с использованием различных интерфейсов: SHDSL, E1, RS232

Usage example description

Purpose: uniting two Ethernet networks to reach full output in the link by using the bonding mode. In this scheme SG-17R provides either internetwork connection between two Ethernet groups with routing rules or bridge link with shared addressing of the networks united. Transfer rate over each pair reaches 14080 kbit/s. Different transfer rate may be set up in different pairs. It is important that even if on one of the pairs there is a link loss, the performance of the channel does not fail. Up to 6 pairs may be simultaneously linked to a single SG-17R device for SHDSL links based on SG-17R-1RU-CP1-4ETH platform. Up to 8 pairs may be simultaneously linked to a single SG-17R device for SHDSL links based on SG-17R-1RU-CP2-3SFP platform. Besides, in the bonding mode it is possible to unite any kind of channel-forming equipment, through which IP-traffic is transferred: E1, RS-232. Both Ether-HDLC and PPP-multilink may be chosen as protocols.
