SNMP or Telnet Connection Examples
The DSU/CSU can be connected to an SNMP or Telnet system in a number of
ways. Some examples include:
Directly connecting the COM port to the SNMP or Telnet device (Figure 2-4,
Direct Connection).
Connecting the COM port to a network device (e.g., a router) (Figure 2-5,
Connection through a Router).
Connecting the COM port or the AUX port to an external LAN Adapter for
Ethernet connectivity (Figure 2-6, Connection through a LAN Adapter).
Daisy chaining the COM port of one device to the AUX port of the other
(Figure 2-7, LAN Adapter and Daisy Chaining).
Remotely accessing the DSU/CSU through the Facility Data Link (FDL) or the
synchronous data port’s Embedded Data Link (EDL) (Figure 2-8, Remote
Access through FDL/EDL).
NOTE:
EDL is only available on 2-port and 4-port DSU/CSUs.
