Dual Service allows end users that are moving within the same wire center to have the same telephone number working simultaneously at both the new and old locations for up to thirty (30) days while the move is in progress. Dual service is based on availability described below and must be supported by the Qwest switch for the addresses you have specified.
Dual Service is available where facilities permit throughout Qwest's 14-state local service territory. Dual Service is available with business and residential POTS (e.g. Resale 1FR) and Centrex 21 (e.g. Qwest Local Services Platform® (QLSP® Centrex 21) services.
Note: Centrex 21 customers must have identical service (e.g. POTS to POTS or Centrex 21 to Centrex 21) at both the "to" and "from" (T & F) locations. A customer cannot have a POTS line at the F location and Centrex 21 at the T location, or vice versa. For information on feature changes with Dual Service, refer to the Provisioning and Installation section of this document.
Dual Service must be available at both addresses in order to offer this service to the end user.
Dual service works by "bridging" (running jumpers) between equipment in the wire center. Certain switch configurations, including designed or non-switched services such as Integrated Digital Loop Carrier (IDLC) or Digital Remote Switching System (DRSS) will not allow "bridged" service.
A few wire centers in the Qwest territory consist of multiple Remote Service Units (RSUs) and a host switch, all collocated in the same building. You may determine the type of switches present in a wire center by performing an Address Validation in IMA Pre-Order and reviewing the Switch Info Tab. If you do not use IMA, you may open an escalation ticket with the Interconnect Service Center (ISC) at 888-796-9087 to receive this information. Although the RSUs may share TNs, bridged service is not possible between them, or between an RSU and its host. Refer to the table below for more information:
| IF BOTH ADDRESSES ARE: | IS DUAL SERVICE AVAILABLE? |
| In an RSU (One RSU in wire center) |
Yes |
| In the SAME RSU (Multiple RSUs in wire center) |
Yes |
| In the HOST (Main switch type) |
Yes |
| In DIFFERENT RSUs (Multiple RSUs in wire center) |
No |
| One in HOST and one in RSU | No |
Dual Service is not available with other services, such as:
(Note: If IMA returns an "undetermined" response you should not request Dual Service. It is Qwest's policy for our Retail and Wholesale customers not to offer Dual Service for this type of response.)
(Note: This restriction is the result of limitations due to the bridging in the central office that will not allow the service to work. Qwest HSI/Broadband Services must be removed in order to have Dual Service. See below for partial move alternative where you can deconsolidate the HSI/Broadband line from the existing account.
(Note: This restriction is specific to requesting Dual Service and a Partial Move on the same LSR. However, if the end-user has multiple lines and wants to move only one of the lines with Dual Service, you can achieve this via 2-LSRs.You can submit both LSRs at the same time, if you use a related purchase order number (RPON) on both and drop each for manual handling. The 2-LSR process described above is exclusive to simple deconsolidation and full move with dual service. Any other change activity (such as adding or removing features) associated to these requests should be made only on the Move request and will default to the intervals described in the Service Interval Guide (SIG)).
- Request a deconsolidation LSR (ACT = N, Manual Indicator = Y, remarks describing the TN/s that you want to establish on a separate account) for the old location.
- Submit a second LSR to do a full move of the account to the new address and establish the Dual Service.
(Note: This restriction is the result of switch limitations due to the bridging in the central office that will not allow the service to work. The Custom Ringing must be removed in order to have Dual Service, but the custom number will be lost. If the end user has multiple lines, you may wish to request a partial move and provide Dual Service on all lines except the one that has Custom Ringing and move the number with Custom Ringing separately at a later date.)
A non-recurring charge is billed for Dual Service. Rates and/or applicable discounts are available in Exhibit A or the specific rate sheet in your Interconnection or Resale Agreement.

When Dual Service is established, features that are provisioned at the T address will work at both locations. Features that appear at the F address and are being discontinued at the T address will stop working as soon as the T order is worked and Dual Service is established. Features will continue to work at the F location if they are also present at the T location.
Dual Service is available to customers with Hunting as long as the hunt sequence is identical at both the F and T locations.
General provisioning and installation activities are described in the Provisioning and Installation Overview.
General maintenance and repair activities are described in the Maintenance and Repair Overview.
In some situations, it is possible to receive a bill for both addresses for dual service depending on the bill cycle and the specific billing region.
Customer Records and Information System (CRIS) billing is described in Billing Information - Customer Records and Information System (CRIS).
