Need help understanding digit manipulation

[gmail2]

We currently have two circuits for our out going calls and are also subscribed to a product called call 127 which escentially means that you can insert 127 infront of any phone number and the call will get re-routed over a different network which offers cheaper calls. I've been asked to find out how our digit manipulation is setup, and whether 127 is inserted infront of every phone number when a user dials out. I've printed off the data from ld 86 but I'm haing some trouble understanding it - can somebody help me out? Here's a sample of it:

DMI  1 
DEL  4 
ISPN NO
INST 033320
CTYP NCHG 

DMI  2 
DEL  4 
ISPN NO
INST 033326
CTYP NCHG

From what I understand from GHTROUT's FAQ that DEL means the first 4 digits will be replace and INST means that 033320 will be inserted before the number - but when does this happen? where is the condition set? I have loads of these DMI's setup. also what does INSP and CTYP mean?

There's also a second part to this question ... we have several different numbers setup for dialing out. Ie we can press 9, or 8 or 5 (there may be more, can't remember off hand). I've been told that 9 "load balances" between the two circuts while 8 is specific to one of them. How can I find out what numbers are setup for dialing out and how they are routed? The reason why I ask this is because I suspect that when 9 is dialled for an outside line, 127 is inserted, but when 8 is dialed, I don't think there's any digit manipulation. However, the digit manipulation info above doesn't seem to show anything about what number was dialed for an outside line either.

Would really appreciate some help on this.

you are correct in assuming that the first 4 digits will be deleted and replaced with 033320

This will get applied when you dial a dsc, tsc spn

for outbound we use 9 this takes us up to ac1 translation level and our spn in ld 90, this then gives us the rlb (which tells us in which order to dial out ie r1 first r2 second etc) the RLB can be examined in ld 86 this will give you the dmi

so if you use a cps service (carrier pre select) you can insert the network number.

from what you say if 127 is inserted, this is either the acod for your outbound route or a cps number

do a dnb on the 127 number if it returns as acod then it's the specific route acod if it doesn't return anything then its a cps number

Hope this helps

Nice weekend!


It's not getting any smarter out there. You have to come to terms with stupidity, and make it work for you.

You can print the numbers

LD22

REQ prt
TYPE dnb
CUST 0
DN 9, 8, 5

Then look at the "type" that is reported.

AC1, AC2 are BARS, can have DMI
RDB, is a Route Access Code - not BARS, no DMI
CDP, is BARS related and can have DMI

Thanks for your replies - but as usual I have loads more questions !!

Firstly, mikeyb - you said that the digit manipulation from my original post will be applied when I dial a dsc, tsp spn - what are they !!??

>> for outbound we use 9 this takes us up to ac1 translation level
What's ac1 translation level? I was able to go into LD 86 and print off RLB (was also prompted for rli but I didn't kow what that was so I just pressed enter). But I have no ideas what these are - but each one seems to have a DMI and Route associated with it. So I presume that when I dial a certain digit number (eg 900353xxx) it goes to one of these, then this determines which route it should take?

I printed a dnb on 127 and also on 9127 but neither came up, so I presume it's not a route, but rather some digit manipulation? So how do I find out when this manipulation is done?

Thanks GHTROUT for that tip - never knew that.

I'm sure you've given me loads of information in the above, but I really know very little about any of the more complicated features of meridian. I'd really appreciate some more help on this.

Thanks again

dsc distant steering code, between two sites
tsc trunk steering code, used in tandem, call comes in on a trunk and you send it out on another trunk.
both under cdp in ld 87

spn.. special number, not a nxx (local) or npa (area code)

911, 1010288 those were just spn's at one time, ld 90

anything you send to the rlb has the dgt applied..

if i allow 911 to go to 911 dispatch, i add spn 11, send it to rlb 11, send that to route 11, use dgt 11 to del 2 and insert 911.. i can't use rlb 11 for any other routing..
