Octet 3.2 Octet 3.2 is used to hold information including Carrier Identification

Codes (CIC). A CIC is three-digit number used to access the switched

services of a particular long-distance carrier from a local exchange line.

All long-distance carriers, and many long-distance resellers, have their

own unique CIC. One or more CIC codes are assigned to each carrier.

Some examples of CIC are:

 MCI VNET: 222

 AT&T Communications: 288

 Sprint: 333

Octet 4 Octet 4 is used to hold information representing coding values for features

and services. Service providers supply the coding values.

The octet contains eight bits numbered from 1 to 8 and from right to left,

so that Bit 1 is rightmost and Bit 8 is leftmost.

The bits contain values representing the following functions:

 Bits 1-5=The binary Facility Coding Value for the specified

feature or service.

 Bit 6 indicates whether the facility is a feature or a service:

 0=The requested facility is a feature.

 1=The requested facility is a service.

 Bit 7 is always set to 1

 Bit 8 indicates whether the requested facility has associated

parameters or is binary:

 0=There are parameters associated with the requested

facility and they are specified in Octet 5.

 1=The requested facility is a binary facility. There are no

parameters.

Octet 5 Octet 5 is used to hold information representing coding values for

parameterized facilities.

The octet contains eight bits numbered from 1 to 8 and from right to left,

so that Bit 1 is rightmost and Bit 8 is leftmost.

The bits contain values representing the following functions:

 Bits 1-7 represents the parameterized field coding value.

 Bit 8 is for future use.
