Configuring the G.SHDSL Interface on SRX Series Devices

This topic provides information on the minimum steps required to configure a G.SHDSL interface on SRX Series devices. The configuration example uses an SRX210 Services Gateway, the information is also applicable to the SRX240 device.

Topology Diagrams of the G.SHDSL Mini-PIM

The following topology diagrams show various G.SHDSL Mini-PIM connections:

Figure 19 shows the topology for the G.SHDSL Mini-PIM operating in the 2X4-wire mode.

Example: Configuring the G.SHDSL Interface on the SRX210 Services Gateway

The following assumptions are made in this example:

The G.SHDSL Mini-PIM is installed in the first slot of the SRX210 device chassis; therefore the FPC used here is fpc 1.
The SRX210 device is connected to a DSLAM (IP DSLAM and ATM DSLAM).
The steps to configure the G.SHDSL interface when the device is connected to an IP DSLAM and ATM DSLAM are given separately (see Table 31 and Table 32.

Table 30 provides the basic configuration steps for the G.SHDSL interface on an SRX210 device.

Table 30: Basic Configuration of the G.SHDSL Interface

Tasks	Commands
Select the operating wire mode (2-wire, 4-wire or 8- wire). Note: When the wire mode is set to 8-wire, one physical interface (IFD) is created. Similarly for 2-wire mode and 4-wire modes, four IFDs and two IFDs are created respectively.	From the [chassis] hierarchy level, enter: set chassis fpc 1 pic 0 shdsl pic-mode 1-port-atm (1x8-wire configuration) set chassis fpc 1 pic 0 shdsl pic-mode 2-port-atm (2x4-wire configuration) Note: The 2x4-wire configuration is the default configuration and behavior. set chassis fpc 1 pic 0 shdsl pic-mode 4-port-atm (4x2-wire configuration)
Configure the line rates.	From the [edit] hierarchy level, enter: set interfaces at-1/0/0 shdsl-options line-rate 4096
Set the annex type.	From the [edit] hierarchy level, enter: set interfaces at-1/0/0 shdsl-options annex annex-a
