G.SHDSL
Item 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 multiple protocols with protocol
identifying information being contained in each packet header. Despite the
extra bandwidth and processing overhead, this method may be
advantageous if it is not practical to have a separate 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
