4xE1 Module with 120Ω Interface
The 4xE1 network module provides four E1 interfaces (through four RJ-45 connectors) that provide the
following functions:
• AMI or HDB3 coding
• Framed, multi-framed, and unframed framing support
• Network performance monitoring and reporting
• Test loopbacks (both line and link)
Table 12 provides the RJ-45 interface pinout for the 4xE1 network module.
4xE1 Module with 75Ω Interface
The 4xE1 network module provides four E1 interfaces (through a single DB-25 interface) that provide the
following functions:
• AMI or HDB3 coding
• Framed, multi-framed, and unframed framing support
• Network performance monitoring and reporting
• Test loopbacks (both line and link)
Table 13 on page 39 provides the DB-25 interface pinout for the 4xE1 network module. A separate
breakout panel is available to provide 75Ω BNC unbalanced interfaces (see Table 14 on page 39 for the
pinout of the 75Ω cable). Figure 4 displays the E1 breakout panel.
