8 Operation on an SHDSL Access
The ARGUS supports the following types of access (access modes):
ATM:
Asynchronous Transfer Mode
STU-R
(STU-R: SHDSL Transceiver Unit - Remote)
The ARGUS simulates the customer side (the modem) and the PC
based on the ATM protocol.
STU-C
(STU-C) SHDSL Transceiver Unit - Central Office)
The ARGUS simulates the switching-side (the DSLAM) based on
the ATM protocol.
STU-R bridge
The ARGUS simulates the customer side (the modem) based on the
ATM protocol. In bridge mode, the ARGUS replaces the SHDSL
modem and passively passes on all of the ATM packets sent back
and forth between the Ethernet side and the SHDSL interface.
STU-R router
The ARGUS simulates the customer side (the modem) based on the
ATM protocol. In router mode, the ARGUS replaces both the modem
and the router. In doing so, it will route all of the packets between the
Ethernet and SHDSL interface with or without NAT.
EFM
Ethernet in the First Mile (see IEEE 802.3ah)
STU-R
(STU-R: SHDSL Transceiver Unit - Remote)
The ARGUS simulates the customer side (the modem) and the PC
based on the EFM protocol.
STU-C
(STU-C: SHDSL Transceiver Unit - Central Office)
The ARGUS simulates the switching-side (the DSLAM)
based on the EFM protocol.
STU-R bridge
The ARGUS simulates the customer side (the modem) based on the
EFM protocol. In bridge mode, the ARGUS replaces the SHDSL
modem and passively passes on all of the packets sent back and
forth between the Ethernet side and the SHDSL interface.
STU-R router
The ARGUS simulates the customer side (the modem) based on the
EFM protocol. In router mode, the ARGUS replaces both the modem
and the router. In doing so, it will route all of the packets between the
Ethernet and SHDSL interface with or without NAT.
