You can also use the ZyXEL Device to connect two geographically dispersed networks over
the ADSL line. A typical LAN-to-LAN application example is shown as follows.

Figure 2 LAN-to-LAN Application Example

The ZyXEL Device is compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data
rates attainable for each standard are shown in the next table.

Table 1 ADSL Standards

DATA RATE STANDARD
ADSL
ADSL2
ADSL2+
If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+
upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not
support Annex M.
The standard your ISP supports determines the maximum upstream and
downstream speeds attainable. Actual speeds attained also depend on the
distance from your ISP, line quality, etc.
