ACCULINK 316x DSU/CSU
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.
