Product Description
Custom Ringing Service provides end-users with up to three additional telephone numbers on one line, in one location, without installing any additional lines. Each number has a unique ringing pattern, allowing end-users to determine in advance of answering a call which telephone number was dialed.
The ring pattern is identified by the second suffix in the Feature Code (USOC). A, B and C are used for the 1st, 2nd and 3rd numbers respectively. A specific pattern may be given if requested.
Refer to the Ring Pattern Table below for a description of each type of ring.
The main line ring does not change. Anyone calling a Custom Ringing Service number will hear a normal ringing pattern.
If the Custom Ringing Service end-user has Call Waiting on their primary number, a unique Call Waiting tone is also provided on the Custom Ringing Service number.
Custom Ringing telephone numbers may be listed in the telephone directory, Additional Listings rules and charges apply.
Availability
Custom Ringing Service is available in selected 5ESS®, DMS™-10, DMS-100 (including remotes) central office switch types and one party service.
The Custom Ringing Service telephone number must be assigned out of the same central office switch or control group as the main line.
Some central offices have more than one switch or control group. In these instances it is imperative that the Custom Ringing Service number be assigned from the same central office switch or control group as the main line.
Custom Ringing Service is available with the following services in selected 5ESS and DMS-100 switch types only:
- Centrex 21
- Centrex Plus
- Centrex Prime®
- Centron®
Custom Ringing Service is not available with:
- Party Line Service
- Combination Service (one line working at two or more locations)
Custom Ringing Service is not available in ID-North.
Only one Custom Ringing Service number is offered in a DMS-10 central office switch types. The ringing pattern available in each switch is as follows:
- A DMS-10 central office switch type can only provide ringing pattern A.
In the DMS-100 switch type where there is a NPA (area code) overlay, the NPA of the Custom Ringing Service number must match the NPA of the main number it is assigned to. If the NPAs do not match, the Custom Ringing Service cannot be provisioned.
When selling Custom Ringing Service with other products which have a distinctive ring such as IntraCall® and Continuous Redial, the ring patterns may conflict, resulting in fewer options for the end-user.
DMS-10 central office switch type:
- End-users can purchase only one Custom Ringing Service number per line. In addition, only Pattern A is available.
- Custom Ringing Service cannot be suspended separately from the main line.

Compatibility & Restrictions
| Feature/Service | Rules/Restrictions |
Billed Number Screening |
Billed Number Screening may be installed on Custom Ringing Service numbers. For each Custom Ringing Service number screened show the FID /TBE after the appropriate Custom Ringing Service USOC. |
Call Forwarding Busy Line/Don't Answer |
The Custom Ringing service is interactive with Call Forwarding Busy Line/Don't Answer subject to the following conditions:
End-users cannot use Call Forwarding Busy Line/Don't Answer features to forward a busy and/or don't answer condition from their primary telephone number to their Custom Ringing Service number. Although the Custom Ringing Service number is forwarded with the primary telephone number, the ringing pattern does not carry forward. |
Call Forwarding Variable |
Call Forwarding Variable may not be installed on a Custom Ringing Service number. However, when a Call Forwarding Variable is installed on a primary telephone number, incoming calls to both the primary telephone number and the Custom Ringing Service number(s) will be forwarded whenever Call Forwarding Variable has been activated, subject to the following conditions:
If a Call Forwarding Variable end-user only wants incoming calls to the primary telephone number to be forwarded, show the FID/MCFI after the Call Forwarding Variable USOC. |
Call Transfer |
Custom Ringing Service is not compatible with a primary telephone number that is also equipped with Call Transfer except in 5ESS/5RSM (remote of 5ESS switch) or DMS-100 central offices. |
Call Waiting |
Call Waiting may not be installed on a Custom Ringing Service number. However, if Call Waiting is
installed on the primary telephone number, a unique Call Waiting tone will also be heard when the Custom
Ringing Service number is dialed. If Call Waiting Deactivation has been activated on the primary telephone number, the Call Waiting tones are also deactivated on the Custom Ringing numbers. |
| Caller ID with Privacy +™ | Custom Ringing Service and Caller ID with Privacy + are not compatible in a DMS-100 central office. Caller ID with Privacy + is available with Custom Ringing Service in a 5ESS central office. Calls to a Custom Ringing Service number associated with an end-user's main telephone number will receive Caller ID with Privacy + treatment. The normal ring pattern for Custom Ringing Service will apply instead of the Privacy + distinctive ring (short, short) for both the main telephone number and Custom Ringing Service number. The way to tell if the call is Privacy + or Custom Ringing Service, is by looking at the Caller ID display. The display for an audible identification by Privacy + will be "Privacy +". |

| Foreign Central Office (FCO)/Foreign Exchange (FX) | Custom Ringing may work with some Foreign Central Office/Foreign Exchange Lines. However, because of the way FCO/FX lines are provisioned between two different Central Offices, the custom ringing pattern may not carry forward to the terminating location. |
