information and cable requirements. If the E1 connection is made via the BNC connectors, connect the TX
BNC of the 3086 to Recive (RX) BNC of the local E1 device, and vice versa.
•
To connect the 3086’s E1 port to a Telco terminated E1 line jack, use a straight through twisted pair patch
cable. Consult with your E1 service provider for exact pinout information and cable requirements.
The 3086 T1/E1 port can be configured via DIP switches, HTTP/SNMP, or command line interface (CLI).
This section discusses DIP switches and HTTP (web server) configuration, for CLI and SNMP information
see Appendix E on page 163.
DIP Switch Configuration
Switch configuration in the 3086 is to be used in situations where the 3086 functions as a DSL modem carry-
ing TDM (E1) data only without resorting to the use of a PC for configuration.
Note
The Model 3086 is shipped with all DIP switches set to the ON posi-
tion. While in this setting, the Model 3086 can be configured only
via software (console, Telnet, HTTP, SNMP). If you want to use the
DIP switches to configure the Model 3086, see section “Switch S2-8”
on page 43 to activate the DIP switch configuration option.
The Model 3086 includes two eight-DIP switch banks labeled S2 and S3. They are externally accessible by
removing the plate on the bottom side of the unit.
