The SSI is the LMC1000, and runs at +various speeds up to 10Mbps. It requires an external CSU/DSU for +operation on T1/E1 lines. The HSSI card is the LMC5000, and runs at various +speeds up to 52Mbps. It requires an external DSU for operation on DS3 lines. +The DS3 is the LMC5245 and runs at a speed of +45Mbps. It has no internal clock generator, and does not require external DSU for DS3 operation. The T1 card is the LMC1200 and runs at a speed of 1.544Mbps or +2Mbps for E1 operation, without CSU/DSU. +.Pp +The +.Op Fl i Ar iface +argument given to +.Nm +should be the logical interface name associated with the Lan Media +device (lmc0, lmc1, etc...). +.Pp +The +.Nm +command given without any additional flags retrieves the current card +settings from the driver and prints them out. +.Sh OPTIONS +The options are as follows: +.Pp +.Bl -tag -width Fl +.It Fl i Ar interface +The interface name of the Lan Media card (default is lmc0) +.It Fl l Ar speed +To manually specify line speed, in bits per second (for devices without built-in CSU/DSU) +.It Fl c +Sets the interface to use an external clock source. This +is only valid for SSI/HSSI cards. +.It Fl C +Set the interface to use internal clocking. On the SSI card this uses the +internal baud rate generator. On the HSSI card it uses the PCI bus clock. +This is only valid for SSI/HSSI cards. +.It Fl e +sets 16 bit CRC +.It Fl E +sets 32 bit CRC +.It Fl k +enables layer 2 keepalive +.It Fl K +disables layer 2 keepalive +.It Fl s +turn DS3 scrambler off +.It Fl S +turn DS3 scrambler on +.It Fl o +Program the DS3 card for cable lengths of less than 100 feet. In this mode, +the card uses lower power to transmit data for short cable runs, which might +otherwise overdrive a receiver.
