Proscend SHDSL ruter /
modem do 2.3 Mb/s |
| |
|
Proscend 5111 SHDSL ruter predstavlja
odlično rešenje za LAN-to-LAN i
LAN-to-Internet vezu preko standardne telefonske parice (pogledajte
gornju sliku). Na sebi ima UTP 10/100 Mb/s port preko
koga se spaja na hab ili svič u lokalnoj (LAN) računarskoj mreži.
SHDSL port se povezuje na bakarnu paricu preko koje može ostvariti brzinu do
2.3 Mb/s. Maksimalan domet je prilično veliki - u praksi se obično 2.3
Mb/s može postići na iznajmljenim linijama dugim 5-7 km a zatim brzina
počinje da pada. Maksimalan domet je do 15km, često i više ali naravno to
zavisi od kvaliteta i prečnika parice. Instalacija je zaista jednostavna jer
uređaj poseduje Web management uz konzolni i Telnet pristup a podržan je
SNMP protokol. Poseduje veliki broj naprednih funkcija koje se po pravilu ne
mogu naći kod sličnih uređaja drugih proizvođača - spomenućemo napredni
Firewall, sigurnosne access liste, VPN (Virtual Private Networks)
PPTP/L2TP/IPSec tunneling (spajanje više LAN mreža
preko Interneta uz kriptovanje saobraćaja radi sigurnosti),
DMZ host/Multi-DMZ/Multi-NAT (DMZ=
demilitarizovana zona), Virtual server mapping, DHCP, DNS... Osim
ruter / modema koji ima Ethernet UTP port Proscend proizvodi i SHDSL modeme
sa G.703, V.35 i X.21 interfejsima. G.703 NTU se obično koristi za
vezu između telefonskih centrala i/ili ISDN PRI remote access servera i/ili
raznih multipleksera - za E1, ISDN PRI i sl. linije. Modemi sa V.35 i
X.21 interfejsima se obično spajaju na rutere i tako koriste za LAN-to-LAN
vezu - ipak savetujemo korišćenje Proscend 5111 ruter / modema kao jednog
uređaja što je i jednostavnije i ekonomičnije. Detaljne
karakteristike uređaja možete videti u
nastavku. Napominjemo da Proscend kao OEM/ODM proizvođač stoji iza mnogih
poznazih etiketa kao i da neki od najvećih svetskih telekoma poseduju
instalacije sa hiljadama, pa i desetinama hiljada Proscend SHDSL i ADSL
uređaja. |

Proscend SHDSL NTU E1 2.048 Mbps
(Nx64K) G.703, LCD |
|
|
|
Proscend 5000-EAL, SHDSL NTU E1 interface AC input with LCD display, offers
two different ways to connect customers to high-speed TDM services with two
G.703 E1 interfaces (balance 120Ω RJ45 jack and unbalance 75Ω dual BNCs).
The G.703 interface will carry 64kbps to 2.048Mbps.
The SHDSL NTU can be configured and managed via EOC, or menu-driven VT100
compatible Asynchronous Terminal Interface, either locally or remotely.
Proscend 5000-EAL is equipped with an auto rate capability that
identifies the maximum line rate supported by the copper loop. This powerful
automatic configuration capability makes installation and service
provisioning simple and painless. Further flexibility is provided in the
ability to manually set the maximum NTU speed at different levels for
different customer-tailored service offerings.
