Connecting Cisco CEoIP Network Modules to the Network
Balanced drivers allow EIA/TIA-449, EIA/TIA-530, EIA/TIA-530A, V.35, and X.21 signals to travel
greater distances than EIA/TIA-232 signals. All balanced interfaces easily support 4 to 8 Mbps.
Using Cisco 12-in-1 Interface Cables with the 4-Port Serial Interface Network
Module (NM-CEM-4SER)
Table 3 lists the Cisco 12-in-1 interface cables supported by the 4-port serial interface network module.
Use the cable part number to order replacement or spare cables for the interface and DTE or DCE mode
appropriate for your network.
Figure 4 illustrates how to connect the Cisco 12-in-1 cable to the network module.
