REVIEWING THE REAR PANEL DESIGN

The IQ 710 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 man-
agement applications (see Figure 2).

V.35 Nx56/64 Connector

The DTE should be connected to the V.35 connector (labeled V.35). The maximum cable length is 100 feet. Table 2
on page 24 shows the pinout for the V.35 Winchester-style connector.
