Connection of the remote offices to the head office and to Internet with using of ADSL(ADSL 2/2+) concentrators
(DSLAM)
|
For necessity providing of connecting to Internet of the different offices or branches, located in the distance an about 5-7 km from head office, it is possible to use ADSL technologies.
ADSL technology can be created then, when the datastream from offices or branches is asymmetric ( upload speeds is more than download speeds ). The typical example of such offices are, for example, shops, administrative district , banks etc.
The head office can thus, on a concordance with automatic telephone system services, to set on the automatic telephone system own concentrator (DSLAM) and to come forward as independent ADSL service provider for the branches.
The environment of data transmission at ADSL technology is a copper telephone line from offices to the nearest ground of automatic telephone system, where is set the head office concentrator (The Data transmission is passed simultaneously with a telephone traffic).

In this case in the offices can be
created:
|
1. DYNAMIX UM-A4
Plus (4 LAN) ADSL2/2+ modem/router (See on a picture Office 1). This device provides support up to 4 Ethernet ports and Firewall. Full Rate ADSL Router provides the full rate maximum 8Mbps download speed and with maximum 1 Mbps uploads. Dynamix UM-A4
Plus (4 LAN) has 4 Ethernet ports, that sufficiently for providing of Internet services for small office.
2. For individual access in Internet can be used DYNAMIX
UM-A – universal ADSL modem/router (See on a picture
Office 2) with USB and Ethernet ports and Firewall support, with full rate 8 Mbps download speed and 1 Mbps
uploads.
By using of additional network switchboard the number of subscribers of office can be easily
doubled.
3. For individual access in Internet can be used DYNAMIX UM-AU – universal ADSL modem with USB port
(See on a picture Office 3) It is economical and advantageous decision for connecting of notebooks and computers with USB
interface.
4. At a necessity connecting to the provider on speeds more than 8 Mbps downstream and 1 Mbps upstream can be used ADSL2/2+ modems/routers, for
example, DYNAMIX UM-A Plus - universal ADSL2/2+
modem/router with Ethernet and USB ports and Firewall support - with speeds of transmission to 24 Mbps downstream and 1 Mbps
upstream.
The choice of modem type is based both on necessary for this office high speed of transmission and on possibilities of Internet Provider (the type of the equipment that by provider used
can be - ADSL2/2+ or ADSL).

In the side of head office can be created :
|
1. 16-48 ports ADSL concentrator (DSLAM)
16-48 ports ADSL DSLAM with built-in POTS splitters provid broadband data service over existing copper wires without affecting the conventional voice
service.
2. For corporate access in Internet can be used DYNAMIX
UM-A(1 LAN) – universal ADSL modem/router (See on a picture
Office 2) with USB and Ethernet ports and Firewall support, with speed of transmission up to 24 Mbps downstream and 1 Mbps upstream.
The choice of modem type is based both on necessary for this office high speed of transmission and on possibilities of Internet Provider (the type of the equipment that by provider used
can be - ADSL2/2+ or ADSL).
