This section describes the new J-series Services Routers features, available with the JUNOS 7.4R4 release. For more information, see the following manuals:
For more information about the JUNOS Internet software that runs on Services Routers, see the manuals listed in Table 4.
J4300 and J6300 Services Routers now support a 2-port symmetric high-speed digital subscriber line (G.SHDSL) Physical Interface Module (PIM) that can be configured in 2-port two-wire G.SHDSL Annex A or Annex B mode.
The PIM allows you to configure an Asynchronous Transfer Mode (ATM) interface over G.SHDSL to send network traffic through a point-to-point connection to a DSL access multiplexer (DSLAM). G.SHDSL interfaces are not supported on J2300 Services Routers.
The G.SHDSL interface supports ITU-T G.991.2 (G.SHDSL specifications), ITU-T 994.1 (G.HS specifications), and ITU-T 997.1 (Physical layer management). To configure an ATM-over-SHDSL interface:
You can also use the CLI to configure the ATM-over-SHDSL interface by identifying the chassis slot and mode at the [edit chassis fpc] hierarchy level and then configuring ATM-over-SHDSL properties at the [edit interfaces at-pim/0/port] hierarchy level. For more information, see the J-series Services Router Configuration Guide.
The J-Web graphical user interface provides new Quick Configuration pages that allow you to configure stateless firewall filters for IPv4 and IPv6, and apply them to configured interfaces. To configure stateless firewall filters using Quick Configuration, navigate to Configuration>Quick Configuration>Firewall Filters.
