Dial Timer—The amount of time, in seconds, after which dialing is assumed to be
ended if no further digits have been received: 6-60. This parameter applies to the
video dial feature. The RS-366 specification does not require all calls to be ended
with the EON (End of Number) digit. If no EON is available, the CBR software uses
the Dial Timer to determine when dialing is complete. The CBR software resets the
timer each time a digit is received. When the timer expires, the dialing is assumed
to be completed, and the RS-366 driver forwards the call to the call handling task
for further processing.
When used alone, the CBR V.35 interface is used in the lease line environment,
and all of the interface signals are forced to on. When used with RS-366, the CBR
V.35 interface is used in a switched environment. The DSR and CTS&DCD options
allow you to emulate the switched environment by specifying that certain
interface signals should go off in alarm conditions.
DSR Option—Specifies the behavior of the DSR interface signal:
Forced On—Force the DSR signal to on in all conditions.
Follow DTR—Direct the DSR signal to follow the DTR signal.
Toggle—Toggle the DSR signal off for three seconds and then to on after the
DSC goes off.
CTS&DCD Option—Specifies the behavior of the CTS and DCD interface signals:
Forced On—Force the CTS and DCD signals to on in all conditions.
Follow DTR—Direct the CTS and DCD signals to follow the DTR signal.
Follow DTR & DSC—Direct the CTS and DCD signals to follow the DTR and
DSC signals.
Admin. Status—Administrative status: In Service or Out of Service.
Configuring the CBR
Card
The only type of configuration you can perform on the T1/E1 UNI card is to put it
in service or out of service.
To put the T1/E1 UNI card in service or out of service, follow these steps:
1 From the Configuration Management menu, select [1] Manage Card.
2 From the List Card menu, shown earlier in Figure 51, select [7] CBR. The CBR
T1-DSX or CBR E1 Configuration Selection menu appears, as shown earlier in
Figure 93.
3 Select [5] Card Configuration to display the CBR Card Configuration menu.
Figure 98 shows the CBR E1 Card Configuration menu. The CBR t1-DSX Card
Configuration menu is the same.
