Procedures:
A. Verify that DID number range has ONE prefix only and not more than 1000 phones per PRI. If you have more than one DID prefix, you must use 6100 software E6.2x or higher. You can then use AANDE instead of ANCD (see below) and you must assign different prefixes to different tennants. Avoid if possible due to the problem of having to remember to add/move phones and keep the tennant number correct. If you use AANDE, you only have to assign the stations to a different tennant number. You can leave other stuff common in ASYD 92-94. Also, set ASYD 246, B5=1
B. Verify with the LEC that the ISDN PRI has outgoing ability
as you order it.
C. ISDN PRI is set for ESF (normal).
D. Program up ISDN PRI per NEC manual - except switch setting for ISDN PRI card is wrong in circuit card book. Switch 1-1 must be off or D Channel will not come up.
E. Verify incoming caller ID works on display phones OK once
ISDN PRI is up.
F. Make arrangements with E-911 specialists at LEC to do
test.
G. Program up ACNP. Outgoing ONLY!; RT=Route of B channels; CNP=1
H. Program up ACND. CNP=1;
Skip=0;
ADD:6 (Local Area Code and your Prefix)
I. Make a test call to a phone with Caller ID to make sure you are sending correct information. Do this from more than one phone to verify.
J. Make arrangements with LEC E-911 coordinator to test your E-911 via ISDN PRI. They will have someone in Translations Dept. delete the BTN (Billing Telephone Number) from that account.
Beware that this might screw up billing for other outgoing calls on this ISDN - PRI! Make a long distance call so they can trace the billing on the account. The 911 center typically gets two
phone numbers on an incoming call - the BTN and any associated account (outside ground start trunk group in our case) for reference. Make sure these other lines are DIT'd to a phone so that if the
911 center gets garbage and they call back on the other number, that hopefully it rings somewhere!
K. In Ameritech region, the customer can sign a PS-ALI contract to purchase software so they can update the distant E-911 file every time a phone is added or moved to a different room!
L. Our experience with an IMG v70 6000 software Version DE 4.10 and a IMGx, with 6000 software Version DE 6.20 was good. The customer saved $100 per month by not having to buy dedicated Camma trunks. With an analog solution, Ameritech wanted loop start Camma trunks; NEC requires tie trunks - you would have had to buy a convertor as well to make that work.
M. Be sure to set up 911 calls to go out the ISDN PRI first, then overflow if they are busy. Make sure that 99% of the time that there will be one or two lines available on the ISDN PRI. Check AMND for number of digits (911 and 9911) and set up 911 and 9911 using separate AOPR routes for each. Have dedicated ground start trunks for most outgoing calls, then overflow to ISDN PRI route for other calls.
N. You can collect incoming caller ID on SMDR on a PRI circuit with the following:
ASYD 1-241 = 12; 1-288=28; 1-296=01
ARTD B Channel Route CDN 98=1
This is great for catching hackers and bomb threats
O. CCIS issues. If you have CCIS with other units in the same town, make sure all phones get DID service through the ISDN PRI at the host site. If in a different town, route 911 calls out that building. Will distant (2000 or 2400) send info to the host 2400? Good luck.
P. If you have DRU's that are out of town, check with the local 911 center.
Q. We did the first installation of this kind in Illinois and the first NEC in the Ameritech region.
R. As long as the system has 6100 Series E6.2x or higher then, SVI:1709
allows Multiple CPN/NXX in the system. It then uses the same AANDE.
As such, one can use the AANDE Command and it can be programmed
exactly the same way you would with the MF trunks. In a multiple
tenant environment, up to 10 digits for each tenant (maximum of 255
tenants) are allowed.
S. Yes, the new NEAX 2400 analog caller ID station card (eight [8] ports
per card) will pass: incoming analog caller ID, Feature Group "D" ANI
from T-1 as well as ISDN Calling Party Number (CPN), ISDN Billing
Number (BN) and ISDN Individual Calling Line Identification (ICLID).
A single line station user may use a "caller ID" display unit or a
caller ID phone or even a caller ID answering machine purchased from a
local store. The NEAX 2400 must be 6200 software to use the feature.
I have not seen an application note on this subject yet so I don't
know how features like call forwarding and call transfer effect the
caller ID information.
T. Warning: Using command ACCD to change change numbers coming in on a PRI, also changes what is sent to the E-911 center. You might be sending a phone number that really isn't yours if you use ACCD. There's a new command in the IMX (AANDE) that can be used (see above) that appears that it might prevent this problem. Test it to be sure..
U. PRI Note: We did a Siemens CO and set up the switch settings and ARTD-65 with a 5.
V. Warning: We used authorization codes on one job and found out that if the code changed the SFC of the phone , the outgoing caller ID information was wrong for calls going out with a code. We didn't require a code for 911 or 9911, so that shouldn't have messed up 911.
