Dear Friends
At one of our customers we have "just out of the clear sky" observed that OCTEL Serenade 200 S/W 2.0.2-2 (12/26/97) hangs up, when calling in to several lines.
LIC-8 is used, and it has been operating fault free since 1996. Normally we see that the whole LIC-8 is getting defective, but this time 3 out of 8 ports are dead.
Also the modem gives "noise characters" on the screen.
Grounding and ferite beads are checked and found OK.
The VM system has been booted and powered OFF/ON, still the problems are at large.
The DEX 1, L H and PS show no problems.
Any hints?
As a workaround we have taken the 3 analogue lines out of the main VM hunt group.
