atcomsystems.ca/forum Forums TDM Business Telephone Systems NEC Telephones & Systems Need assist with IPKII and ISDN PRI Install

Greetings:

I know its Friday and getting to the end of the day but can anyone assist with a ISDN PRI integration to NEC IPKII 1.5.

At this moment I've been prepping the programming but I'm stuck at the correct pin out for a female DB9 to RJ45 adapter. Once done, I'll plug a patch cord from said adapter to telco's NID. I do have a Digital Link CSU (DL551X) but I would prefer not to use it if possible and the dip switches on the DTI-U40 are set to operate independently of CSU.

Cards:
CPU 1.5 with PKUII-U
(1) ESIB (8) with ESIE (8)
(2) COIB (8)
(3) COIB (4)
(4) ESIB (8)
(5) SLIB (4)
(8) DTI-U40

here it goes:
RJ45 DB9

1.(Blue) DSR(out) 6
2.(Orange) CTS(out) 8
3.(Black) GRD 5
4.(Red) TX(in) 3
5.(Green) RX(out) 2
6.(Yellow) DCD(out) 1
7.(Brown) RTS(in) 7
8.(Gray) DTR(in) 4

Good Luck!

I dunna believe my own idiocy. I completely forgot the serial port on the T1 card is for maintenance and not for the circuit. I need to cross connect the circuit to the MDF depending on the slot which the T1 card is in.

Gah.

Thanks for the assist vad60 but I shot myself in the foot.

OK...
Now that the ISDN is cross connected properly, I seem to be unable to make calls out and I cannot answer incoming calls on all circuits of the ISDN trunk. Sorry if this is one of those RTFM questions but my brain has died some time ago...

INCOMING CALLS:
All phones ring for all incoming calls. The answer button flashes with ringing but I cannot pickup the call or cannot press answer to get the call. I'll look deeper in ext/trunk programming...

OUTGOING CALLS:
All circuits of the ISDN (except b-channel) are in group 1 and I have reversed the priority order so circuit 35 has priority 1 and circuit 13 has priority 23. After pressing 9, attempts to dial outside numbers fail after the second or third digit dialed...

Is the PKUII-U chip upgrade necessary for running a PRI on an IPK II?

No

You have to assign CAP keys otherwise calls cannot be answered.

Only if you have more than 48 ports counting 24 chanels of PRI, stations and Analog trunks.

64 ports on IPK II.


Check these things:

Make sure you are using a DTI-U40.

Make sure that the dip switch 1 on the second bank of switches on the DTI-U40 is set for T1 (DOWN)or PRI(UP).

Make sure your DTI card is at least version 5.01.

Prog 10-03 the settings for D4 or ESF and AMI or B8ZS.

Prog 14-05 make sure trunks are in an outbound route.

Prog 15-07, setup CAP keys or trunk appearances on the phone sets.

Prog 22-02, setup for DID.

Prog 34-01, Wink start.

Prog 22-09, # of inbound digits received

Prog 22-10 and 22-11, routing of DID/DNIS inbound.

I would highly recommend upgrading to 1.60. 1.5 series had issues with voicemail xfer to busy stn not going to user mailbox and PRI dropping calls.
