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.
Table 5-2 provides the 2-port SMIC port assignments.
4-Port SMIC Rotary Switch Positions
Table 5-3 shows the 4-port SMIC serial signal 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.
