Administered connections
An Administered Connection (AC) is a connection between 2 access or data endpoints. Communication
Manager automatically establishes the connection based on the attributes you administer. An AC
provides the following capabilities:
•
Support of both permanent and scheduled connections
•
Auto Restoration (preserving the active session) for connections routed over Software Defined
Data Network (SDDN) trunks
•
Administrable retry interval (from 1 to 60 minutes) per AC
•
Administrable alarm strategy per AC
•
Establishment/retry/auto restoration order based on administered priority
Detailed description
The SDDN provides virtual private-line connectivity using the AT&T Switched Network. Access to the
service is provided via an Integrated Services Digital Network (ISDN) trunk group whose
Service Type
field is SDDN. The system uses the Destination field on the Administered Connection screen to route
calls when AC is active, based on associated authorized time-of-day fields.
Establish an AC between the following:
•
Two endpoints on the same switch
•
Two endpoints in the same private network, but on different switches
•
One endpoint on the controlling switch and another endpoint off the private network
In all configurations, administer the AC on the switch that has the originating endpoint. For an AC in a
private network, if the two endpoints are on two different switches, normally the connection routes via
AAR through tie trunks (ISDN, DS1, or analog tie trunks) and intermediate switches. If required, route
the connection via ARS and Generalized Route Selection (GRS) through the public network. The call
routes over associated ISDN trunks. When the far-end answers, a connection occurs between the far-end
and the near-end extension in the
Originator
field on the Administered Connection screen.
Access endpoints
Access endpoints are non-signaling trunk ports. They neither generate signaling to the far-end of the
trunk nor respond to signaling from the far-end. Designate an access endpoint as the originating endpoint
or destination endpoint in an AC.
Typical AC applications
The following are typical AC applications:
•
A local data endpoint connection to a local or remote-access endpoint. Examples: a modular
processor data module (MPDM) ACCUNET digital service connecting to SDDN via an ISDN
trunk-group DS1 port; an MPDM ACCUNET digital service connecting to an ACCUNET
Switched 56 Service via a DS1 port.
