REVIEWING THE REAR PANEL DESIGN

The IQ 310 rear panel contains two expansion slots (one for Dial Backup and one for a Network Interface
Module), a DTE connector which provides primary channel V.35, and an Ethernet 10BaseT port for
management applications (see Figure 2).
V.35 Nx56/64 Connector
The DTE should be connected to the V.35 connector (labeled V.35) with a maximum cable length of 100 feet.
Table 2 on page 24 shows the pinout for the V.35 Winchester-style connector.
