Description
Transfer Mode
Click on the drop-down list and select Transfer Mode as ATM(Asynchronous
Transfer Mode) or PTM(Packet Transfer Mode).
ATM uses asynchronous time-division multiplexing, and encodes data into
small, fixed-sized packets called cells.
SHDSL interfaces support Packet Transfer Mode (PTM). In PTM, packets (IP,
PPP, Ethernet, MPLS, and so on) are transported over DSL links as an
alternative to using Asynchronous Transfer Mode (ATM). PTM is based on the
Ethernet in the First Mile (EFM) IEEE 802.3ah standard.
*Note: This mode is changed, the system will need to reboot.
Pair Mode
Click on the drop-down list and select Pair Mode as Pair-1, Pair-2 or Pair-4.
Pair-1 for 2-Wire Shdsl.bis Router
Pair-2 for 4-Wire Shdsl.bis Router
Pair-4 for 4-Wire Shdsl.bis Router
STU Mode
Click on the drop-down list and select STU Mode as STU-C or STU-R
STU-C means the terminal of central office and STU-R means customer
premise equipment. For point to point application, STU-C is the
server/master unit while STU-R is the client/slave unit.
Multiplexing
Click on the drop-down list and select Multiplexing used by your ISP as VC or
LLC.
VC-mux (VC-based Multiplexing): Each protocol is assigned to a specific
virtual circuit. VC-based multiplexing may be dominant in environments
where dynamic creation of large numbers of ATM VCs is fast and economical.
LLC (LLC-based Multiplexing): One VC carries multiptle protocols with
protocol identifying information being contained in each packet header.
Deapite the extra bandwidth and processing overhead, this method may be
advantagrous if it is not practical to have a sepatate VC for each carried
protocol.
*This is available only when you select ATM as Transfer Mode.
VPI
Enter the VPI(Virtual Path Identifier) range from 0 to 255.
*This is available only when you select ATM as Transfer Mode.
VCI
Enter the VCI(Virtual Channel Identifier) range from 32 to 65535.
*This is available only when you select ATM as Transfer Mode.
WAN
Item
Description
Mode
Click on the drop-down list and select Mode as Routing or Bridge
Choose Routing if your ISP provides you with only one IP address and you
need several computers to use the same Internet account. Choose Bridge
when your ISP provides you with more than one IP address and you need
several computers to get individual IP address from your ISP’s DHCP server.
When Bridge is selected, NAT, DHCP server and Firewall become unavailable.
*Note: This mode is changed, the system will need to reboot.
Encapsulation
Click on the drop-down list and select Encapsulation used by your ISP as
PPPoE or RFC1483
WAN-IP
Item
Description
IP Address Type
Click on the drop-down list and select IP Address Type as Static or Dynamic
A static IP address is a fixed IP provided by your ISP. A dynamic IP address
is different every time when you connect to the Internet.
IP Address
Enter IP address for WAN when select Static IP address Type.
Submask
Enter a subnet mask in dotted decimal notation when select Static IP address
Type.
