Table 1–1 summarizes the features for each model of the DECbrouter 90.
DECbrouter 90T1
The DECbrouter 90T1 is a Digital Wide Area Router/Bridge consisting of
two interfaces and one console port. The interfaces consist of one Ethernet
interface and one synchronous serial port. The Ethernet interface is either a
ThinWire port (10Base2) or a twisted pair port (10BASET) exclusively. The
synchronous serial port supports one of the following seven standards as
determined by the cable attached to the serial port:
• EIA530A
• RS232/V.28
• RS449/RS422/V.11
• RS449/RS423/V.10
• V.35
• V.36
• X.21 Leased Lines
The console port consists of an asynchronous RS232 serial port.
DECbrouter 90T2
The DECbrouter 90T2 is a Digital Wide Area Router/Bridge consisting of
three interfaces and one console port. The interfaces consist of one Ethernet
interface and two synchronous serial ports. The Ethernet interface is either
a ThinWire (10Base2) port or a twisted pair (10BASET) port exclusively. The
synchronous serial ports support any two of the following three standards,
in any combination, as determined by the cable attached to the synchronous
serial port:
• RS232/V.28
• V.35
• X.21 Leased Lines
The console port consists of an asynchronous RS232 serial port.
