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.
