1-Port Serial Mini-Physical Interface Module (SRX-MP-1SERIAL-R) Overview
Serial WAN links are bidirectional links and require very few control signals. In a basic
serial setup, the data circuit-terminating equipment (DCE) is responsible for establishing,
maintaining, and terminating a connection. A modem is a typical DCE device. A serial
cable connects the DCE to a telephony network where, ultimately, a link is established
with data terminal equipment (DTE). DTE is typically where a link terminates.
Figure 4 on page 15 shows the front panel of the 1-Port Serial Mini-Physical Interface
Module (Mini-PIM).

The 1-Port Serial Mini-Physical Interface Module (Mini-PIM) provides the following key
features:
• Autoselection of operational modes based on DTE or DCE cables
• Local and remote loopback diagnostics
•
Configurable clock rate for the transmit (TX) clock and receive (RX) clock
•
Complete configuration and management by using the CLI and the J-Web interface
