A data communications device (101, 119) may be controlled from a centrally-located network management system controller (109) located some distance from the device. The data communications device is coupled to the network management system controller by a local channel (155, 157). The device includes a link adapter (133, 143) that communicates with the controller by a protocol that allows the device to exchange messages with the controller. As many as 512 devices may be coupled to the same local channel.

Data communications device with resident link adapter

A modem, or data communications device, that is testable independently of a DTE device permits remote testing of it automatically by a network management computer or controller reducing required operator intervention. A data communications network that has possibly hundreds of these modems requires substantially less operator intervention.
