Connecting 3 remote LIMS

[ladeeh]

I have two major issues at hand:

Issue I
I want to connect 3 of my MD 110 remote LIMs. 2 of the LIMs are of thesame version (BC 7) while the other one is BC 12. I am planning to use AIRMUX 200 Radio with E1 connection.
The issues I want to find out are as follows:

a. Will the group switch GJUL4 on the 2 same LIMs work with the Airmux? There was an old UHF 2Mbps radio (A.R.E) that linked these LIMs at one time but the radio has packed up and no solution for repairs because it is obsolete.
b. The BC 12 LIM has TLU76. Do I need IP MUX to convert the analog 2Mbps (from the E1 on the Airmux) to digital for the convenience of the TLU 76 card?
c. Are there better alternatives of achieving same?


Issue II
At one of my remote location (call it LIM 1)with 3 magazines, I have about 300 extensions. Recently about 54 extension are not ringing out to the subscriber end.
These 54 faulty extensions are not tied to only one magazine but distributed to different magazines.
I have changed the 3 TMU cards but the situation is still thesame.
I also changed the REU cards but no success.

What do you think is the problem?

I count on your professional advice.

Cheers.

RE: issue #1,

Unless you're trying to connect all 3 to each other (same GS), as long as the transmission path is an E-1 -- formatting and timing configured correctly -- it doesn't matter what the actual transmission medium is. You shouldn't have any problems.

Good luck,
