Analog line problem

[fcepeda]

Hi,

I need help with this problem:

I have a Definity G3 with a mix of digital and multivendor lines, but some analog lines in a TN429 card does not hang and remain in active status blocking it use. To clear this status I just run busyout and release and instantly are reenable. Other analogs lines never was blocked.

Do it be a Trunk Group configuration problem?

Are they all on the same trunk group?

Hi,

I mistyped this phrase "mix of digital and multivendor lines", the correct one is "mix of digital and analog multivendor trunk lines".

Also, reviewing the symptoms when a line remain hold, always a "stat trunk" command look like this: "in-service/active" but with no "Connected Ports"


TRUNK GROUP STATUS

Member Port Service State Mtce Connected Ports

Hi, Zu56:

No I have see randomly this problem in other trunk group, over diferent TN card 429 or 793, but most often occur in trunk group 5: 3 analog lines group on TN 429 card.

Hi
For loop-star CO trunk in some cases there is a problem of blocking after the call when user's switch hook is activated on stations.
Try to close disconnect supervision In-N, Out-N on first page of trunk-group form. After that you will no able to transfer incoming call from this trunk back again to this trunk, but will no chance to hang it active.
