Managing Data Calls
Administered Connection

Administrator’s Guide for Avaya Communication Manager

Detailed description
Establish an AC between the following:
•
Two endpoints on the same Avaya DEFINITY server or media server
•
Two endpoints in the same private network, but on different servers
•
One endpoint on the controlling server and another endpoint off the private network
In all configurations, administer the AC on the server having the originating endpoint. For an AC in a
private network, if the two endpoints are on two different servers, normally the connection routes via
Automatic Alternate Routing (
AAR
) through tie trunks (ISDN, DS1, or analog tie trunks) and
intermediate servers. If required, route the connection via Automatic Route Selection (
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 AC screen.
Because the system makes an administered connection automatically, you do not use the following:
•
Data Call Setup
Do not assign a default dialing destination to a data module when it is used in an AC.
•
Data Hotline
Do not assign a hotline destination to a data module that is used in an AC.
•
Terminal Dialing
Turn off terminal dialing for data modules involved in an AC. This prevents display of
call-processing messages (INCOMING CALL,...) on the terminal.
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: an 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.
•
A local-access endpoint connecting to a local or remote-access endpoint. Examples: a DSO
cross-connect and a 4-wire leased-line modem to a 4-wire modem connection via an analog tie
trunk.
•
A local data endpoint connecting to a local or remote data endpoint such as a connection between
two 3270 data modules.
NOTE:
The following guidelines do not include AAR and ARS, or GRS administration
information for routing AC calls over trunk groups. See the respective feature elsewhere
in this book for that information.
