Example: The unit receives an incoming call on Port 3. The switchboard looks for an interface who has
matching accept criteria to the number it received. A match is found on interface “Z” that has PORT
SELECTION set to ALIGNED. This causes interface “Z” to only process the call if it has Port 3 available. If all
matching interfaces have PORT SELECTION set to ALIGNED and none of those interfaces have Port 3
available, then a busy or fast busy will be returned to the calling party.
DIAL PLAN (OCTAL E&M MODULE)DIAL PLAN (E&M) > USER TERM
Write security: 3; Read security: 5
This menu allows the user to define option parameters for ports which emulate an analog E&M connection
from the Network (PSTN).
DIAL PLAN (E&M) > USER TERM > IFCE CONFIG
Write security: 3; Read security: 5
Specifies the configuration parameters for the endpoint.
DIAL PLAN (E&M) > USER TERM > IFCE CONFIG > PORTS AVAILABLE
Write security: 3; Read security: 5
Indicates which ports of the Quad/Octal E&M Option Modules have been defined in this switched
endpoint (indicated by “! “), in another switched endpoint (indicated by “s”), or in a DEDICATED MAP
(indicated by “n”). This field is read-only. The following characters may display in this field:
DIAL PLAN (E&M) > USER TERM > IFCE CONFIG > NUMBER OF PORTS
Write security: 3; Read security: 5
Specifies the number of ports ATLAS 550 uses for this endpoint.
CIRCULAR Contiguous ports from last to first.
ALIGNED Provides the ability to maintain alignment between ports as if they were in
dedicated map mode. This scenario requires PORT SELECTION set to
ALIGNED on both interfaces (usually on User Term and on Net Term). An
interface that has PORT SELECTION set to ALIGNED will only process a call
from the switchboard on the same port that the incoming call was received.
0-9 This port is available.
*This port is requesting this port for this connection, but the port is not yet activated.
!This port is used by this endpoint.
SThis port is used elsewhere in the switched DIAL PLAN.
SThis port is in the switched dial plan and conflicts with this endpoint.
NThis port is used in one or more DEDICATED MAPS.
NThis port is in one or more DEDICATED MAPS, and conflicts with this endpoint.
•This port is the wrong kind of port for this endpoint.
