ISDN BRI blocking

[djudjuman]

For testing purpose I have programmed 2*2B+D channels as follows (BC12 SP2):

/*-----------------------------------------------------------------*/
/* tlu79_sl.rou slave side */

/* bri slave */
rocai:rou=1,sel=7111100000000010,sig=011100000031,traf=03151515,trm=5,serv=3110000000,dist=30,disl=128,bcap=111111;
EXECUTED
rodai:rou=1,type=sl60,vari=15400000,varo=06610000,varc=00000314;
EXECUTED
roeqi:rou=1,tru=1-1&1-2,equ=1-0-20-0;
EXECUTED
roddi:dest=00,rou=1,srt=3;
EXECUTED
scexi:feml=1-0-20-0;
EXECUTED



/*-----------------------------------------------------------------*/
/* tlu79_ma.rou master side */

/* bri master */
rocai:rou=2,sel=7111100000000010,sig=011100000031,traf=03151515,trm=5,serv=3110000000,dist=30,disl=128,bcap=111111;

I have made a loop back cable for testing on the TLU79 board:

Individual 1 <----> Individual 2

Tx+ (C26) <----> Rx+ (A30)
TX- (C28) <----> Rx- (A32)
Rx+ (C30) <----> Tx+ (A26)
Rx- (C32) <----> Tx- (A28)

After programming the routes, I can't make calls.
The routes are blocked.

I also tested to loop a TLU79 on position 1-0-20 and another TLU79 on position 1-0-42 and connected a
twisted cable inbetween. The result of blocking is the same.

What am I doing wrong ???

You cant have different var values on the same interface(board).
Use two cards .

[lalrl]

Try Varc=0631 instead 0661 (Master-Slave-Problem)

 

[DUFQI]

pls. check your varo:
064 => slave
066 => master on layer 2, slave on layer 1&3 ???
should be 063
try this

This is data i used to make qsig line between two md's with tlu79 that works.

The wiring between the individs must be crossed
tx - rx
rx - tx
for the individs .

[lalrl]

I did mean varo, not varc - sorry

 

[djudjuman]

Thanks SYAR2003, DUFQI and LALRL for your inputs.
It is working fine now.
By the way: It is possible to have different var values on the same interface(board). I just tested it with a quarter connector where tx and tx are crossed. Works fine

Thanks.

 

[SYAR2003]

Varo/vari is okay i guess , but not varc (common) .

 

[DUFQI]

see alex - restrictions:
When services set with D 4 in VARI (General Protocol Updates or DSS1 Network Side supported), the whole interface must have the same configuration, i.e. the interface cannot be divided into several routes.

An interface cannot be divided into one Public and one Tie line route.

 

[djudjuman]

You are correct DUFQI.
When you use the same interface you can loop back on the same board.


Thanks.
