G.SHDSL PIM

The G.SHDSL PIM (Figure 40 on page 58) provides symmetric high-speed digital subscriber line (SHDSL) physical interfaces to ATM network media types. The G.SHDSL PIM has two ports for ATM-over-SHDSL connections.

The G.SHDSL PIM supports the following key features:

■Onboard network processor

■2-port two-wire mode and 1-port four-wire mode

■Programmable line rates in both modes:

■2-port two-wire mode supports autodetection of line rate and fixed line rates from 192 Kbps to 2.304 Mbps in 64-Kbps increments.

■1-port four-wire mode supports fixed line rates from 384 Kbps to 4.608 Mbps in 128-Kbps increments.

■32 virtual channels per PIM

■ATM-over-G.SHDSL framing

■“Dying gasp” notification

■Local and remote loopback diagnostics

■ITU-T G.991.2, ITU-T G.994.1, and ITU-T G.997.1 standards compliance

NOTE: Payload loopback functionality is not supported on ATM-over-SHDSL interfaces.

For pinouts of cable connectors for G.SHDSL PIMs, see “ADSL and G.SHDSL RJ-11 Connector Pinout” on page 194.

To install or remove a PIM, see “Replacing a PIM” on page 120.

The G.SHDSL PIM has two LEDs to indicate the status of the PIM and its ports.

Table 33 on page 59 describes the meaning of the LED states.
