GRT-501 is product new most belongs to dòng SHDSL mà PLANET vừa đưa ra, GRT-501 is G.SHDSL.bis router tuân according to standard ITU-T G.991.2. GRT-501 provides capability flexible and brand quả the giải pháp connection Internet for environment SOHO (Small Office Home Office- office small and nhà separate) and SMB ( Small Medium Business – công ty vừa and small). GRT-501 supports dải rộng speed transmission data đối xứng from 192kbps tới 5.7Mbps (on 2 dây) and GRT-501 also has thể dùng to connection LAN-to-LAN with khoảng theh up to 6.7km (4.2 miles) mà chỉ need used đường dây electrical thoại sẵn has.
PLANET GRT-501 integrated with capability high-end Bridging / Routing, the function high cấp of DMZ, Virtual Server, and VPN. Với sự phát triển fast chóng of environment network thì Virtual LAN trở should càng ngày càng quan trọng in nền công nghiệp network. GRT-501 supports standard IEEE 802.1Q VLAN chạy on network ATM.
GRT-501 integrated protocol SNMP and management qua Web do that GRT-501 easy dàng used về mặt management also such as configuration. GRT-501 also has thể configuration bằng dòng lệnh Comand-Line Interface and has thể truy cập thông qua Telnet and port console. Người quản trị has thể management according to many theh hợp lý.
Mô hình ứng dụng
Expand LAN network
GRT-501 is giải pháp tuyệt vời for expand network Ethernet chỉ need used đường dây electrical thoại sẵn has. Chỉ need a cặp dây đồng AWG-26 thì chúng ta has thể connection easy dàng 2 network Ethernet theh xa nhau tới 6.7km.
Giải pháp for supplier dịch vụ
G.SHDSL.bis is giải pháp number a to provides network connection speed high, giá thành hợp lý for SMB and SOHO (những nơi need speed connection with speed đối xứng high. Bằng việc tận dụng hạ tầng đường dây điên thoại sẵn has, thiết lập network đơn giản and easy hiểu in when that speed up to 5.7Mbps do that GRT-501 has thể provides the dịch vụ network such as IP Phone, website hosting and the ứng dụng threendwidth rộng.

Characteristics kỹ thuật
- Data transmission speed đồng bộ high: GRT-501 supports technology new most of G.SHDSL.bis and provides transmission data speed high tới 5.7Mbps on 2 cặp dây.
- Supports CO and CPE.
- Supports IEEE 802.1 Q VLAN: GRT-501 supports standard IEEE 802.1 VLAN, provides những lợi ích đáng kể in việc tận dụng threendwidth, thực hiện flexible and bảo mật.
