Overview
Description
The DECserver 90TL Ethernet communications server is a multisession
communications server designed to operate in multivendor environments.
The communications server can be configured as a standalone device or as a
module in the DEChub 90 Ethernet backplane.
The DEChub™ 90 is a multifunction Ethernet backplane that provides mounting,
power, and connections for up to eight Workgroup LAN products.
The communications server downline loads software using MOP or BOOTP
protocols.
The communications server is attached to a ThinWire Ethernet network and up
to eight asynchronous devices. The communications server allows any attached
asynchronous device to establish sessions with services offered either on the
network or on other attached devices. The communications server also enables
network hosts to establish sessions with devices attached to the communications
server. The communications server allows sessions to be established using either
LAT or Telnet protocols.
Communications server management functions are enabled and monitored
through a host system using a remote console facility, Simple Network
Management Protocol (SNMP) or a terminal connected to the communications
server.
Figure 1–2 shows communications server configuration in a ThinWire Ethernet
Local Area Network (LAN).
