How Devices Communicate Once They Are Connected With the exception of the system console(and, for certain HP 3000 Series 900 models, the remote support modem and the first UPS on the system), which has its own access port, asynchronous devices are connected to a HP 3000 Series 900 computer through the Datacommunications and Terminal Subsystem (DTS). DTS includes all of the Datacommunications and Terminal Controllers (DTCs) connected to the local area network (LAN), a LAN interface card(LANIC) connecting each host to the LAN, the LAN cable, and the software that controls all of the DTS hardware. This software resides on the HP 3000 and on the DTC. During configuration, a relationship is specified between the system's LANIC and each DTC through which asynchronous device connections will be made. A linkfor the LANIC is defined using the Node Management ConfigurationManager (NMMGR) utility. This link provides the asynchronous devices with an entry point to the DTS.
