Connection of the remote offices to the head office on the dedicated lines with using of SHDSL concentrators
(DSLAM)
|
For necessity providing of connecting of the different territorial distributed offices or branches, located in the distance an about 5-7 km from a central office and it is possible to use of SHDSL and ADSL
technologies. SHDSL technology can be created then, when the datastream from offices or branches is symmetric ( upload speeds and download speeds are the same).
The typical example of such offices can be, for example, shops, administrative district , etc.
The environment of data transmission is the dedicated copper line (own or leased).
At the number of branches more than 3-4 the using of SHDSL concentrator (DSLAM) is optimal solution for the central office.

In this case in the offices can be
created:
|
1. DYNAMIX UM-S4 SHDSL
modem/router (See on a picture Office 1). This device provides support up to 4 Ethernet ports and allows connecting to 4 computers of users to Internet, that usually sufficiently for small offices and branches. At the use of this device safety of access must be provided additional programmatic or hardware on the user side . In place of DYNAMIX UM-S4 SHDSL modem/router is possible to use the similar SHDSL modem/router - DYNAMIX UM-S4F, with built in (Firewall) - protection
function.
2. DYNAMIX UM-S SHDSL
modem/router (See on a picture Office 2). This device has one Ethernet port and allows connecting either one user (one computer) to Internet, as shown on a picture or with the using of the additional office Ethernet switchboard - to provide connecting of all computers, included in an office network. At the use of this device access protection must be provided additional programs on the user side.

In the head office can be created :
|
1. SHDSL concentrator (DSLAM), providing directly a concentration and data exchange with remote offices. It is possible the using also of analogy SHDSL concentrators of other
vendors.
2. For corporate Internet access in a central office can be used DYNAMIX UM-A (1 LAN).
It is the universal ADSL modem/router with USB and Ethernet ports and Firewall support, if it is necessary the speed of connection with the provider up to 8 Mbps downstream and 1 Mbps upstream or more speeds.
DYNAMIX UM-A Plus is the universal ADSL2/2+ modems/routers with Ethernet and USB ports and Firewall support - with speed of transmission up to 24 Mbps downstream and 1 Mbps upstream.
The choice of the modem type is based both on necessary for this office high speed of transmission and on possibilities of Internet provider (by the type of the equipment used - ADSL2/2+ or ADSL).
