ARN Technical Specifications

X.25 PAD Connections

The ARN provides X.25 PAD functions that enable the router to access X.25 services through the 8 ports of an attached breakout box. The PAD establishes and maintains links with the packet switch network, assembles and disassembles packets, communicates with the character terminal, and handles special control processes for the character terminal.

You connect the X.25 ports using an RS-232-D serial connection as shown in Table C-12.
