Chapter 5 Serial Mobile Interface Card Signals for the SMIC The Cisco Single-sideband (SSB) Serial standard supports the following: • EIA/TIA-232, EIA/TIA-449, EIA-530, EIA-530A, X.21, and V.35 standards in both DTE and DCE modes. • Signals (SSB and LED) are provided through the 60-pin multifunction header(s). The position of the rotary switch determines the port assignments. Although the rotary switch has eight positions, only positions 0, 1, and 2 are supported on the 4-port SMIC, and only positions 0 and 1 are supported on the 2-port SMIC. Table 5-1 provides 4-port SMIC port assignments.

The position of the rotary switch determines the port assignments. Although the rotary switch has 8 positions, only 1 of 4 positions can be selected. The rotary switch position should be unique for each mobile interface card (MIC) card.
