RS232 DATA PORT 2 Network The DIU 2131 can be in a node controlled by an SCC or NCM Management controller module. These controllers can be managed by the Craft interface, SNMP or Node Manager. Remotely located users can also use Telnet over Ethernet or SLIP to access the Craft interface. -
Page 11: Quick Set-Up
Chapter Quick Set-up The DIU 2131 multiplexes data from a high-speed and low-speed application onto a shared T1 line. The high-speed application could be a file server, router, bridge, video teleconference codec, or any device with a synchronous connection. The low-speed application can be up to 64 kbit/s, or one T1 timeslot. -
