InterNetwork Calling Name - V6.0

History Log

Product Description

InterNetwork Calling Name (ICNAM) Service enables you to offer "Caller Identification (ID) with Calling Name Service" to your end-users. With ICNAM, end-users with ICNAM capable Customer Premise Equipment (CPE) and the Caller ID feature can receive the calling party's name and telephone number to be displayed on their CPE. ICNAM allows you to query the CenturyLink™ Line Identification DataBase (LIDB) and obtain the listed name information for the telephone number being called. LIDB is the database where CenturyLink, and other providers contracting the use of CenturyLink's LIDB Data Storage Service, store their end-user's name and telephone line numbers.

If the calling name is not available and the end-user has not requested privacy, CenturyLink will deliver city and state information.

ICNAM Service is a component of CenturyLink's Common Channel Signaling (CCS)/Signaling System 7 (SS7) network. Access to CenturyLink's LIDB/ICNAM is provided through CenturyLink's Common Channel Signaling Access Capability (CCSAC) via a CCS Link. You may obtain your connection to CenturyLink's CCSAC either directly through your own SS7 network, or you may contract with a third party, or Hub Provider, to interconnect with the CenturyLink SS7 network. More information about CenturyLink's CCSAC/SS7 network can be found in the CCSAC/SS7 web page.

If you also subscribe to LIDB Storage Service, CenturyLink stores your end-user's name information in LIDB and delivers it to any Caller ID subscriber.

Subscribers to CenturyLink's ICNAM Service have access to all end-user's calling name information stored in the CenturyLink LIDB/ICNAM database, with the exception of information for end-users who have instructed CenturyLink or their local service provider to block that information. End-users can instruct their local service provider to place a privacy indicator on the calling name information stored in the LIDB/ICNAM database. Per Federal Communications Commission (FCC) regulations, CenturyLink will deliver this customer's caller name information to you and it is your responsibility to program your End Office switch to not deliver this caller name information to your end-user.

Implementation

Product Prerequisites

If you are a new Competitive Local Exchange Carrier (CLEC) and are ready to enter the Interconnection business with CenturyLink, view the Getting Started for Facility-Based CLECs web page.

ICNAM Service is negotiated and made available through your ICNAM Services Agreement

You must have CCSAC capability prior to, or in conjunction with, ICNAM Services. See the CCSAC/SS7 web page for information on ordering SS7 and Switching/Signal Transfer Points (STP) links and ports.

If you contract with a Hub Provider for CCSAC service, the Hub Provider is required to furnish a Letter of Authorization (LOA) to CenturyLink to ensure CenturyLink has your approval to provide services.

If the records for a telephone number which you have ported are stored in CenturyLink's LIDB/ICNAM database, you are responsible for updating the Number Portability Administration Center (NPAC) subscription record with the LIDB or Caller Name DataBase Destination Point Code. For more information about ported numbers, see the Local Number Portability (LNP) web page.

Pre-Ordering

General pre ordering information is located in the Pre Ordering Overview.

Ordering

  • All information necessary for activating and billing ICNAM Service.
  • Information necessary for an Access Service Request (ASR) to be submitted by your CenturyLink Sales Executive on your behalf. The ASR is strictly for billing purposes.

Provisioning

Provisioning information and design requirements are available in Technical Publication 77342.

CenturyLink will exercise reasonable efforts to provide accurate and complete ICNAM information in CenturyLink's LIDB/ICNAM database. The ICNAM information is provided on an As-Is Basis from the LIDB/ICNAM data record. CenturyLink does not warrant or guarantee the correctness or the completeness of such information. CenturyLink will access the same LIDB/ICNAM database for your queries as CenturyLink accesses for its own queries. CenturyLink will not assume liability for system outages or inaccessibility or for losses arising from your authorized use of the ICNAM data.

As an additional service enhancement, CenturyLink will return city and state information when a calling party's name is not available in CenturyLink's serving area.

You will need to arrange your Calling Party Number based services in such a manner that when a calling party requests privacy, you will not reveal that caller's name or number to the called party (your end-user). You will comply with all FCC guidelines and, if applicable, the appropriate Commission rules, with regard to honoring the privacy indicator.

CenturyLink retains full and complete ownership and control over the LIDB/ICNAM database and all information in its database. You agree not to copy, store, maintain or create any table or database of any kind from any response received after initiating an ICNAM query to CenturyLink's database.

Network Impacts

SS7 network overload due to extraordinary volumes of queries and/or other SS7 network messages can have a detrimental effect on the performance of CenturyLink's SS7 network. CenturyLink, in its sole discretion, will employ certain automatic and/or manual overload controls in the CenturyLink SS7 network to safeguard against any detrimental effects. CenturyLink will report to you any instances where overload controls are invoked due to your SS7 network, and you agree in those cases to take immediate corrective actions as necessary to cure the conditions causing the overload situation.

CenturyLink may need to temporarily discontinue the ICNAM Service if your TCAP errors are so excessive as determined by CenturyLink to jeopardize the viability of the ICNAM Service.

Frequently Asked Questions (FAQs)

1. Why is the city and state sometimes displayed instead of the calling name?
A calling party's name may be unavailable for the following reasons:

  • The record is not yet in the LIDB/ICNAM database because the number is a new connect.
  • There has been trouble on the network.
  • There is no service agreement between CenturyLink and the service provider of the calling party.

When the calling party's name is unavailable, CenturyLink has elected to respond with the city and state instead of a message like "unavailable" or "out of area".

2. Does the LIDB/ICNAM database provide the telephone number information that is displayed?
No, the originating End Office of the calling party provides the calling number. The calling number is then used to query the LIDB/ICNAM database for the calling party's name information.

3. What is the difference between ICNAM and Calling Name (CNAM)?
ICNAM is an acronym for InterNetwork Calling Name Service and CNAM is the acronym for Calling Name. Both refer to the same service. ICNAM is the term used by CenturyLink.
