Voice-Grade Data Access Endpoints on Definity (ACM)

Here's one for the old timers - or otherwise very experienced - Definity users out there!

There have long been a couple of standard Definity features (since Release 5 or so, if memory serves) called Access Endpoints and Administered Connections. I have an application for these features that I cannot get to work.

Specifically, one type of Access Endpoint - a port on a TN760 analog tie trunk pack - when connected via Administered Connections to a second Access Endpoint of the same flavor, will emulate a four-wire, analog, type 3002 private line data circuit. From the Avaya Administration Manual for Release 11:

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 Administered Connection.

The following are typical AC applications:

A local-access endpoint connecting to a local or remote-access endpoint.

Examples: .... a 4-wire leased-line modem to a 4-wire modem connection via an analog tie trunk.


This is the exact application I am trying to implement.

From the screen reference for Access Endpoints in the Admin. Manual, for the field 'Communication Type' the valid entries include voice-grade-data for an analog tie trunk Access Endpoint (AE).

I have set up two AEs of type 'voice-grade data', have them properly connected together via an Administered Connection, but we cannot get the modems attached to the AEs (TN760 ports) to 'talk' to (or even hear) each other. Since analog modems use audible frequencies, we tried connecting a tone generator to the transmit pair on one port and a butt set on the receive pair of the other and still no audio between the AEs.

Has anyone ever tried this, or does anyone have any ideas for things I can try that I may not have thought of? There's apparently no one left at Avaya who has even heard of the feature, so they're no help.
 
Are you running tx and rcv and then flipping rcv and tx on the other side, as in DCE/DTE

What does status admin give you?
