E1 Emulation

[van]

Yes I have no idea when it comes to E1 lines. All I know is the cable resembles a normal LAN cable.

 

So here's the thing. I am nowhere near a E1 line, yet I have to install and make sure that out telephony card works. It is a Dialogic D/600JCT-1E1.

 

I have installed the card into a machine that was running a Dialogic D/120JCT-LS card (successfuly), so the DCM stuff was already installed. DCM picks up the card (albeit as a 2E1 card...) but I cant test it because as I said: I'm not near a E1 line.

 

Can anyone tell me if there is some software (did I mention the word free or trial version?) that can do a basic simulation of a E1 line using a normal network card?

 

Anothe question: I can't seem to find isdiag. Where is this executable?

No easy answer here. You need to just wait and get the E1 line provisioned, and then plug it into the back of the Dialogic card. Then configure the card to match the ISDN protocol on the E1 line.

 

The only alternative would be to find a PBX with an E1 port on it. That would let you prove the Dialogic card works, but setting up the link to PBX may be harder then setting up the Dialogic to use the E1 line from Telco's switch...

No such thing. Ethernet controllers are for Ethernet connections, they cannot do E1/T1 connections.

sigh... okay then.

 

Thank you for the quick reply.

Van: Bit late for a reply now (as you probably have your E1 lines by now) but, just is case: You can wire 2 E1 ports in a crossed-path/crossover connection, so that one E1 can talk to the other E1. Fairly easy to do if you have 2 cards. You need to obtain/make a special connecting cable which crosses over the recv/transmit pairs and then configure one E1 to operate in 'Network/NT' Mode and the other end in 'Terminal/TE' mode. Then both cards can talk to each other. Of course you will need to use some software on each end to make/recv the calls. VG on the TE end is obvious, if you have access to TAPI on the NT end, use Windows Dialler or similar program to dial VG over the crossover link. If not TAPI then use some other dialogic dialler to make the call.

 

You might (no promises here - just guessing) be able to set one port of the D600 in NT mode and other in TE mode, so only need one computer/dialogic card.

 

Finding some software to make the calls is the tricky bit.

 

I have used 2 Eicon PRI cards back-to-back using this method and it works (using TAPI). I have also used E1/PRI capable PABX to connect the card. When using a PABX thou, usually have a fixed 'mode' at the PABX, ie: its set to TE mode only and you can't change it, so the IVR card has to be NT mode - it should still work thou.
