4 Cables
4.1 Synchronous Cables – WAN interface
When configured for sync, the DB25F WAN ports have an RS530 DCE pin configuration (compatible
with ISO 2110). RS232 is a subset of RS530, so a WAN port has a standard RS232 pin assignment
when configured for RS232 (V.24).
4.1.1 Connecting to a DCE device
The following cables are used when connecting to DCE device (like a modem) with a female connector
that is supplying clocking on the DCE transmit and receive clock pins.

4.1.2 Connecting to a DTE device
The following cables are used when connecting to DTE device with a male connector that expects to
receive clocking on the DCE transmit and receive clock pins. If replacing a modem, avoid any modem
handshake issues by configuring the device's interface for “leased line” or “permanent modem” type
connection.
