3.12 WAN and ATM Virtual Connection

GRT-101/GRT-401/GRT-402 has two types of WAN ports: physical WAN port
(SHDSL) and logical WAN ports (WAN 1~8). The physical WAN port connects
GRT-101/GRT-401/GRT-402 to the WAN. The logical WAN port or ports allow
you to create virtual WAN connections for plural destinations. When
configuring the physical WAN port, you can change the SHDSL physical layer
protocol setting. To configure logical WAN ports, you must provision ATM
virtual connections for each logical connection. The instructions for each are
shown below.

3.12.1 SHDSL operation

There are two SHDSL operation modes: STU-R and STU-C.
GRT-101/GRT-401/GRT-402 supports both operation modes and
automatically trains up to the ideal line speed. This enables the maximum
operative rate as determined by the central office SHDSL equipment, or you
could configure the connection rate directly.
Note: Optimal line rates are dependent upon the central office equipment base and optimal line conditions.
Follow the procedure below to change SHDSL physical layer setting.
To set the SHDSL operation mode to STU-R, enter:
