I have a customer that has two buildings with a MISC connecting both buildings. They
wanted the second building to have its own phone system and still be connected with the
other building. So we installed another MISC and E&M cards. I have my target lines built and the E&M lines in pool B. when I call from one switch to the other switch using pool B the call will only ring on the prime set. If I go to control set for lines and have no prime set for the E&M lines the call from the 1st switch will ring from the phone that’s making the call but the 2nd switch wont ring anywhere. When I put the prime set back in to play with the E&M lines the call will only ring on the prime set. This is the way its works if switch 1 calls switch 2 and visa versa. I have the target lines setup as if they were DIDs. Any suggestions? It’s been about 8 years since I’ve worked with E&M lines.

If these are copper 4 wire E/M circuits, do you have your E & M leads reversed between the systems?

Yes sir i do

Have built your routes and destination codes?

And what version of software are the MICS's?

E&M Access code is to grab a dial tone from another switch to be able to dial any extension in that building or use any other features including outgoing calls from that switch. You can't use your internal features by using E&M card. With P2P PRI you can connect 2 switches together by ordering MCDN key codes for Networking advance features such as Centralized VM, Transfer across the network and etc.

I remember them, but only ever dealt with them in SL-1/Meridian 1 situations.

Do you have the E&M lines set to Auto Answer?

Sorry guys I haven’t been back to the site yet. I’ll be back to the site after Thanksgiving and let you know what i find.
Have a good holiday.

Try checking on Signaling, Wink vs Immediate.
What about DTMF senders, and receivers at both ends?
DID translation Tables set up?
When you access the Trunk do you get Dial tone?
