Assigning Time Slots/Cross Connections
The Time Slot Assignment/Cross Connect feature provides an easy method of
assigning time slots for frame relay data and creating cross-connections to the
synchronous data interface. The system allows you to assign DS0s on the T1
network interface and between the user data port and network interface in order to
share the T1 network.
You can also clear cross-connection assignments for the system, or for a selected
slot or interface.
NOTE:
Although it is not required, it is suggested that you progress through each
screen in order, from top to bottom.
Caller Identification Method
Possible Settings: Caller ID, Proprietary
Default Setting: Caller ID
Specifies the method used to identify callers.
NOTE: The Caller Identification Method setting must be the same at both ends of the
circuit.
Caller ID – Incoming calls will only be answered and the frame relay link on this Link
Profile will only be activated when the Caller ID received from the switch matches one of
the configured Inbound Calling IDs.
Proprietary – Incoming calls will always be answered, even when no Caller ID is provided
by the switch, provided the following conditions are met:
Link Status is set to Auto (the default).
At least one ISDN Link Profile is enabled.
When using the Proprietary method, the unit queries the originating unit for its Local
Phone Number. If the returned phone number matches one of the configured Inbound
Calling IDs, the call is accepted. If the queried unit does not respond with its phone
number within five seconds, the unit drops the call.
Alternate Outbound Phone Number
Possible Settings: 0 – 9, *, #, space, _ , –, (, or )
Default Setting: none
Specifies an alternate phone number to call (the ISDN Called Party Identifier) when a call
using the primary Outbound Phone Number was unsuccessful. Up to 18 valid characters
can be entered. Each Outbound Phone Number must be unique. If not, the
Alt
Outbound Phone Number is Not Unique
message appears and you must enter
another phone number.
NOTE: For every originating (alternate outbound) phone number entered, an
answering (inbound) phone number must be entered at the far end, and vice versa.
Currently active calls are not effected when this number is changed.
