G.SHDSL PIM
The G.SHDSL PIM (Figure 40 on page 66) 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.
Figure 40: G.SHDSL PIM
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 240.
To install or remove a PIM, see “Replacing a PIM” on page 174.
The G.SHDSL PIM has two LEDs to indicate the status of the PIM and its ports.
Table 33 on page 67 describes the meaning of the LED states.
