3.12 WAN and ATM Virtual Connection

GRT series has two types of WAN ports: physical WAN port (SHDSL) and logical WAN ports (WAN 1~8). The physical WAN port connects GRT series 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 series 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:

admin# setup shdsl mode STU-R

To set the SHDSL operation mode to STU-C, enter:

admin# setup shdsl mode STU-C

To set link type to 4 wire, enter:
