AT-MC601 and AT-MC602 Installation and User’s Guide
The PSTN port allows you to connect the AT-MC601 Subscriber unit to a telephone and the AT-MC602 Provider unit to the outside telco box. This port features an RJ-11 connector.
Table 2 lists the RJ-11 port pinouts and their assignments.

The AT-MC601 and AT-MC602 network extenders each have one twisted pair Ethernet port. The twisted pair ports feature RJ-45 connectors with a maximum operating distance of 100 meters (328 feet). For the port pinout details, refer to ”RJ-45 Port Pinouts” on page 15.
Type of Cabling.The 10/100Base-TX twisted pair port on the AT- MC601 and AT-MC602 network extenders are designed to operate with Category 3 or better unshielded twisted pair cables. For 10 Mbps operation on the twisted pair ports, Category 3 or better 100 ohm unshielded twisted pair cabling is required. For 100 Mbps operation on the twisted pair ports, Category 5 and Enhanced Category 5 (5E) 100 ohm unshielded twisted pair cabling is recommended.
Auto MDI/MDI-X.An RJ-45 twisted pair port on a 10/100 Mbps Ethernet network device can have one of two possible wiring configurations: MDI or MDI-X. The RJ-45 port on a PC, router, or bridge is typically wired as MDI, while the twisted pair port on a switch or hub is usually MDI-X.
The AT-MC601 and AT-MC602 network extenders feature automatic MDI/MDI-X. Each port automatically determines the configuration of the port on the device to which it is connected and then configures itself appropriately. For example, if a port on a network extender is connected to a port on a bridge, which is typically wired as MDI, the port on the network extender automatically configures itself as MDI-X. This feature allows you to use either straight-through or crossover cables when connecting devices to the network extender.
