Dual-Port T1 or E1 PIM

The Dual-Port T1 PIM (Figure 25) and Dual-Port E1 PIM (Figure 26) provide a physical connection to T1 or E1 network media types. Each PIM has two physical T1 or E1 ports with an integrated channel service unit (CSU) or data service unit (DSU).

The Dual-Port T1 and E1 PIMs provides the following key features:

• Onboard network processor
• Integrated CSU/DSU—Eliminates the need for a separate external device
• 56-Kbps and 64-Kbps modes
• ANSI T1.102, T1.107, and T1.403 standards compliance
• G.703, G.704, and G.706 E1 standards compliance
• Independent internal and external clocking system
• Loopback, bit error rate test (BERT), T1 facilities data link (FDL), and long buildout diagnostics

For pinouts of cable connectors for T1 and E1 PIMs, see E1 and T1 RJ-48 Cable Pinouts.

Status LEDs indicate port status. Table 29 describes the meaning of the LED states.
