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 40 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 40 for the

pinout of the 75Ω cable). Figure 4 displays the E1 breakout panel.
