Table 7-4 shows which options are supported by the ADSL2+ Annex A module
and which options are supported by the Annex B module. As you can see, the
ADSL2+ Annex A module supports all the options listed. The ADSL2+ Annex
B module, on the other hand, supports ADSL2, ADSL2+, and G.DMT. The
ADSL2+ Annex B module also supports the Multi-Mode option, but when this
option is used with this module, only three training modes are possible:
ADSL2, ADSL2+, and G.DMT. (In future versions of the Secure Router OS,
additional training modes will be supported by the ADSL2+ Annex B module.)
Standard Description
ITU G.922.3 ADSL2 Trains the interface for the ADSL2
(G.dmt.bis) transmission rate. This mode
requires a splitter at both the user's
and the public carrier's premises to
divide traffic between voice and
data lines.
ITU G.922.5 ADSL2+ Trains the interface for the ADSL2+
transmission rate. This mode
requires a splitter at both the user's
and the public carrier's premises to
divide traffic between voice and
data lines.
ITU G.992.1 (G.dmt) Trains the interface in the full-rate
ANSI standard. This mode requires
a splitter at both the user's and the
public carrier's premises to divide
traffic between voice and data
lines.
ITU G.922.2 (G.lite) Supports the splitterless ANSI
standard with a smaller bandwidth
than the full-rate ANSI standard.
Automatically detects the
appropriate configuration and
conforms to the standard used by
the DSLAM. This is the default
setting.
ITU G.992.3 Annex L Trains the interface to use
READSL2 READSL2.
ANSI T1.413 Issue 2 Supports lower-speed
connections than the full-rate
ANSI standard.
