Drop Calls over E1/T1 with Adtran ESU 120e . . . .

[Anonymous]

There's no active alarms but got a question the

Remote Alarm & Frame Slip showed into the history of the ESU  ... what means ?

Remote alarms are an indication that the device on the other side of the T1 was sending an alarm to the ESU.  So a remote alarm on the Drop Port 0.2 would tell us the PBX was sending the ESU an alarm.  The PBX is showing 'Power Failure Kind : AIS error'.  AIS stands for Alarm Indication Signal but I'm not sure how that connects to the Power Failure the PBX mentions.  The frame slip and clear seems to be a reaction to the alarm being received.

BTW ....

The other ESU where we're connecting its a TSU 120, in wich one we have the following.  Could be somekind of wron parameters beetwen both ESU's ?

Is the TSU on the opposite side of a point to point connection from the ESU?  If so it's not likely to be part of the problem, it just means somewhere in the connection they are converting from the T1 to the E1 at your side.  What we've been seeing is an alarm coming to us from the PBX.  The TSU should have nothing to do with that.  The settings provided look normal for a point to point connection.  You have 16 DS0s for data and 8 going to the PBX for voice.
