CESID Assignment 1

[lmb2]

I am looking for an example of what should be programmed into the CESID field on the CESID Assignment form. My objective is to make sure that if a Teleworker in New Zealand or Maine dials 911 that the CESID indicates that the call is from New Zealand or Maine. Our offices are located in Nebraska.

The help file indicates that up to 10 digits can be programmed...what should this value be? The users home phone number? Zip Code? Country Code?

Thanks in advance for your help.

It is important that the 911 call is presented to a local 911 service. If the caller in New Zealand dials 911 and gets a Nebraska operator, the number presented is useless.

CESID is more applicable to sites that reside within a unique 911 zone but are not located at the same address AND they share outcalling trunk resouces.

A university campus for example might have all of the outgoing lines located on one system with sets distributed amongst many buildings. In this environment, you would plan your 911 dialing with your Telco to have unique numbers assigned for each building for CESID. Each phone within said building would then be configured to present that number when dialing 911.

Hope this helps.

I was under the impression that Enhanced 911 services routed calls to a Public Safety Answering Point (PSAP) and the information provided in the CESID was used to route the call to the appropriate emergency services district. If that is indeed the case the information contained in the CESID should indicate that the caller is in New Zealand even though the outpulsed caller ID phone number is located in Nebraska.

If that is not the case how do I indicate that the caller is in a different location than the home office? I am less concerned about the user in the UK than I am about the users scattered through-out the U.S.

The LIM (Line Interface module) that fits into the back of the 5220 etc. You then attach a local annalogue line to the LIM. This allows emergency calls out via that. Also acts as basic resiliency if the link goes gone to HQ

The LIM defeats the cost saving purpose of having a teleworker phone in the users home office...you retain the LD savings but in some cases the MRC to maintain an analog line out weighs the LD savings.

Surely there has to be another way to indicate the users location to the PSAP.

Don't you have to have an analogue line to get Broadband??

Most of our users have cable modems.

2 considerations:

1 - I find it difficult to accept that these phones are located at a site where there is no local dialing lines.

2 - If this is a cost saving measure, consider the liability issues if 911 service is required and not delivered. Anything you might save in LD charges could not possibly cover the cost of the lawsuit.

I did not say that the phones were located where there are no local dialing lines, I simply stated that the company does not provide an analog line for these home based offices. In most cases the users have their own personal residential line and/or cell phone.

What I am trying to plan for is the possibility of a user or a member of the users family being in an emergency situation where the wrong phone is picked up in a panic and used to dial 911.

You are correct in your assumption that when an emergency call is made, the CESID assigned to the DN is sent out to the PSTN. The CO uses the CESID to route the call to the local PSAP. The PSAP uses the CESID to pull up information such as the address, building, floor, area, and callback number.

CESIDs are public network Listed Directory Numbers that you will need to request from a local carrier.

I would start by contacting your local carrier to see if they can give you the CESID for your remote users based on their home office location. If they cannot you will need to contact the local carrier for each of your remote users.
