Table 15: Gigabit Ethernet RJ-45 Connector Pinout
Table 16 lists the cables that you can order from Juniper Networks to connect to a
port on the serial PIM. The device to which you are connecting and the serial
interface type determine which cable you need.
Table 16: Juniper Serial Cables
The E1 and T1 PIMs use an RJ-48 cable, which is not supplied with the PIM.
Table 17 describe the RJ-48 connector pinouts.
