This is my TD1232/TVS100 installation ailing again..
TVS has 4 ports, & all calls to CO lines are directed to ext 165 ( i.e. these 4 ports).
TD1232 uses jacks 22 & 23 for the TVS.

I got a call from the department that uses
this system, saying
that they could make only one call into the system- second call got RNA.

Please confirm that I am diagnosing this right..

Here's what I did:

I could establish 2 simultaneous calls - third gets RNA.

From a system phone, if you dial 165 or 166 - it
gets the voicemail system.
167 & 168 - "NOT VALID" in display on system phone.

First thing I thought was bad extension port
in the TD1232..

I changed the "Bad" jack ( 23-1 & 23-2 ) back to
a normal port, and plugged in a system phone.
Worked fine.

I checked the settings in 117 & 118 - they
show 22 & 23 as voicemail ports( correctly).

Checked continuity from 22 & 23 jacks on the block
to the modular line cords that plug into the
TVS-100 port cards. This was OK.

Plugged in my laptop, and rebooted the TVS..
All 4 ports are recognized. DPITS online.

I powered down the TVS, swapped the port cards.
powered up. Again, (laptop showed) all 4 ports
were recognized, but this time ** DPITS not established **

I powered down, swapped them back, powered up.
DPITS established, and again only the first
two ports ( 165 & 166 ) work.

I vote for a bad TVS port card ( #2 )..
Am I missing anything?

Thanks to this great group!
