Figure 33: E3 PIM

The T3 and E3 PIMs provide the following key features:

■Onboard network processor

■Integrated DSU—Eliminates the need for a separate external device

■Subrate and scrambling options with support for major DSU vendors

■Independent internal and external clocking system

■Loopback (payload–supported only on T3 PIM, local, and remote), bit error rate test (BERT), and T3 far-end alarm and control (FEAC) diagnostics

For pinouts of cable connectors for T3 and E3 PIMs, see “E3 and T3 BNC Connector Pinout” on page 240.

To install or remove a PIM, see “Replacing a PIM” on page 174.

Status LEDs indicate port status. Table 28 on page 60 describes the meaning of the LED states.
