Selecting the Shared

Communication Port

Communication between the Model 3161 DSU/CSUs in the 3000 Series Carrier and an external PC (attached either locally or through an external modem) occurs through a shared communication (COM) port (refer to the COMSPHERE 3000 Series Carrier Installation Manual for cabling information). Unlike standalone Models 3160/3164 DSU/CSUs, the Model 3161 DSU/CSUs do not have a dedicated COM port for external access. Therefore, one circuit card in the carrier must be selected as the Master Communication Unit, which provides the COM port for all circuit cards in the carrier. Once configured as such, the Master Communication Unit differs from circuit cards in the carrier because it now has COM port configuration options that can be selected. These options are used to configure Port 2 on the Auxiliary Backplane as the COM port for the carrier.

NOTE

If a Model 3161 DSU/CSU is configured as the Master Communication Unit, Port 2 cannot be used as a data port.

To select the Master Communication Unit for the carrier,

1.Use the Select button on the SDCP to choose the desired unit in the carrier (see Selecting a Model 3161 DSU/CSU in Chapter 2, Installation).

2.Press F3 to select Config from the top-level menu screen.
