PRA T1

[krzysioD]

Hello There,

as i live in Europe, and recently received T1 PRA card for common hardware, i will gladly:

a) sell it
b) exchange to any of PRA E1 or PCM 2 also for common hardware.

card was used for testing with some opensource softswitches like asterisk and callweaver.

T1, T2 (E1) and DLT2 - the same board.
This boards have different label (on front panel) and real difference - on the board you have strapping (1,2,3,4 - managed by soldering).
If all point opened - you have T2, if you close strap 2 - you will have DLT2.
Take soldering iron, remove solder from all strapping point (1,2,3,4) - you will have T2 board.

for E1 (T2) <> DLT2 i know that we've tested in OXO and it worked. Good to know that in OXE it works too.

I will maybe do some pictures and step-by-step guide.

I have all open and it's a T1.
3EH72007ADAA KKZZA 01

or maybe you could solder it to: PCM R2

after some ironing:

or
6/11/08 13:29:26 000001M|001/01/-/---|=3:2021=Bad coupler type: PRA awaited

works as DASS2

I've soldered DIP: and tested all possibilities,
only the T1-PRA and E1 DPNSS2 could be set.

so pls say what was serial number/product number of your board and what you did to setup it as MG E1 PRA ISDN.

We use DLT2 board (used like DLT2 or E1) 3EH76037ABAA 04
I will try to manage this board like T1.
3EH72007ABBA KMZZA 01 - another present reference number.

[krzysioD]

My got's:
3EH 72007 ADAA KKZZA 01
3EH 72007 ADAA KMZZA 01

on board (soldered numbers)

and sticker: 3EH73007ACAD 06 PRA-T1.

IT does not work as PRA E1 or PCM 2mbps.

I've made dip switch, 2^4 = 16 possibilities and tell my pabx to delete card 1,4 and declaere every possible MG- trunk side card,
while logging output and saving incidents.

Tried:
MG_PRAT1
MG_PRAE1
MG_PRAE1_CAS
MG_PRA_DASS2
MG_PRA_DPNSS
MG_IVR_Z30
MG_IVR_Z24

Really a nice play.

point 1 closed, manage (really PRA-T2) board like MG-PRA T1 - DPT1 board in services.
All point opened, manage board like MG-PRA E1 - PRA board in services.

All open -> normally this card is NO so i whould switch my dipswitch to "ON" so, it would connect ground to the 1 2 3 4 pin ot atmel uCPU.

So it's not PRAE1 compatible.
