Carrier Identification Parameter (CIP)
Overview
These Codes Unlock Efficiency
Go ahead -- mix multi-carrier traffic on one trunk group. Verizon will provide the carrier identification codes for you using our Carrier Identification Parameter (CIP) service. What's more, CIP reduces the number of trunk groups you need for transmitting calls. And since your facility requirements decrease, you can resell the extra capacity to smaller carriers.
How It Works
When calls are made, multiple carrier codes are identified on a trunk group that sends calls from one central office to another. CIP is a field in the SS7 Initial Address Message containing the codes that identify the different carriers. It sends the appropriate carrier codes to your switch along with your calls.
Benefits
- Verizon's CIP service saves you money by combining mixed traffic over a trunk group.
- The service allows you to bill specific carriers on a shared trunk group.
- CIP lets you analyze traffic detail to plan future business strategies.
- CIP enhances your current Feature Group D access service. That means you can offer new virtual network products that increase revenue and give customers more choices in services.
Applications
- Take advantage of CIP's custom routing capabilities to maximize functionality for your customers.
- Prioritize traffic and combine your trunk groups for greater efficiency.
- Use CIP to brand your calls so customers recognize you.
- Offer customers new services that add new revenue sources to your portfolio.
CIP
Description
Verizon Carrier Identification Parameter (CIP) service allows carriers to identify traffic generated by multiple Carrier Identification Codes (CIC) on a single trunk group.
CIP is a field in the SS7 Initial Address Message that contains the CIC. The field can be populated by four-digit codes for identification. CIP service uses those Identification Codes on a trunk group, allowing you to consolidate your trunk groups and still track the source because the information is passed along with the call. When CIP is provided, the switch will transmit the 4 digit CIC of the presubscribed line or the CIC selected when the end user places a call using 101XXXX dialing. Verizon CIP service enhances your current Feature Group D switched access service and permits you to offer new virtual network products. The end result is increased revenue and a broader portfolio of services from which your subscribers can choose.
Availability
CIP is available from Verizon selected end office and tandem switches in connection with originating Trunkside BSA 101XXXX Option and FGD when out of band signaling is specified. A complete list of Verizon offices equipped with CIP is maintained in Telecordia's Local Exchange Routing Guide (LERG), section 7.

Features
There are no optional features with CIP.
Applications
Verizon delivers CIP to carriers who order the service on Feature Group D, 700, 800/900 NXX database calls that are placed over SS7 trunk groups that you designate to have CIP capability. Using CIP, you can:
- Combine your trunk groups for improved efficiency and still maintain the ability to identify carrier codes.
- Use a single trunk group to identify traffic coming from multiple carriers and reduce costs.
- Brand calls to build customer recognition in the industry.
- Take advantage of customized routing for greater customer satisfaction.
- Analyze traffic detail to plan future business strategies.
- Prioritize traffic to achieve optimum efficiency.
The specific protocol for CIP is contained in Telcordia Document GR-905-CORE, Issue 1, March 1995.
When a call is made, multiple dialed codes, or CICs (Carrier Identification Codes), are identified over one trunk group. A trunk group is the path a call takes from one Central Office (CO) to another. Without CIP, IXCs cannot mix different carriers' traffic on a single trunk group. However, with CIP, varied traffic is carried over just one trunk. This reduces the number of trunks required by an IXC, decreasing the IXC's facility requirements and freeing additional unused trunks for resale.
