CAS system

[user25]

hi every body!

in our company we need to interconnect our MD110 bc9 to the PSTN over digital line "E1" using a CAS signaling, we use a TLU20 card but what TL signaling we must choose? TL30 or TL37?? please also tell me the difference between them!

Muchas Gracias!

I want to add a point: the type of signaling system we want to use is CAS "R1"

 

[user25]

i made a mistake, the signaling we want is R2 not R1!

Hello user25, you should use TL30 for PSTN. Also is important to know if you will need MFC registers, in that case you must also install MFU or MSU/MRU boards. What country are you located?

 

[user25]

we have installed the MFU card this card is reponsible of register signalling!
the link works well and also i have the ANI (A-number identification) this route is used only for incoming trafic from pstn, it is a did route to our operator consol..

however i've 2 problems now:
1- the consol is OPI-II, where the field responsible of displaying the A-number can display only 6 digits, but in our contry A-number is composed of 9 or 10 digits!!
what is the solution to display all th number???

2-when our register receive th complete A-number he sends a signal A-6! so the PSTN can't have information about the state og B-number.. so normaly our register may send
A-3 signal then B-6 signal if the operator is free, so why this dosn't occure??????

this is a tracing made by PSTN to see by yourselves what exactly occures now:
