Interfaces and Connectible Terminals
106
Termination
Each interface card has 16 DIP switches (S1 to S16, two per S
0
interface). The
DIP switches activate the required terminating resistors for the S
0
buses
(100 ohms per S
0
bus). In the default setting, all terminating resistors are
activated (Default: on).
Forum 550 Card 8 S0/T0: Location of DIP switches S1 to S16
Note:
The following configuration information applies to external as
well as internal S
0
interfaces.
Bus configuration: Forum Gateway 560 at the end of an S
0
bus
If the Forum Gateway 560 is connected at the end of an S
0
bus, the
terminating resistors of the relevant S
0
interface cards must be activated.
In a typical configuration, the Forum Gateway 560 will be connected to the
network termination for basic access (NTBA) with an externally switched S
0
port; therefore, all terminating resistors of the interface card are activated in
the default setting.
