Using Alternate Carriers |
| Alternate carriers may be connected to each trunk route group. The selection of the carrier is defined in the least cost routing outdial-rule section. |
7.2.3.1 |
Carrier Access Methods Supported |
Primary carrier |
| When seizing a trunk using the main carrier, the system can use en-bloc dialing or send single digits to the public network to set up the outgoing call. Note that this access method is used when routing calls over the public switching network. |
MCL Single Stage |
| The system calls the selected carrier using a prefix and then dials the destination number. Digits are sent in the D channel when using ISDN service or as normal dialing when using analog service. This selection may be used in CorNet applications for advancing to public network facilities for overflow applications. |
MCL Two Stage |
| The system calls the selected carrier using a prefix in this method as well. After a short synchronization phase, it sends a programmable authorization code and then the destination number using DTMF digits. |
Corporate Network (CorNet) |
| When a corporate network (CN) method is used, the alternate network is connected directly to the HiPath 3000. This can be seen as a company network. LCR determines the trunk group by analyzing the number the user has dialed and routes the call either over the CO trunk group or over the corporate network. This method allows both an open and closed numbering plan to be implemented by manipulation of digits. |
Dial-In Control Server |
| The system calls the selected carrier using a prefix and calls a dial-in control server (DICS). The authorization code and the destination number are transmitted within the SUB address. Dialing information is sent in the D channel. |
Primary Rate Interface |
| The choice of a carrier or of a calling service is encoded in the following information elements: |
| • | Network specific facility |
| • | Operator system access |
| • | Transit network selection |
LCR Dial Plan |
| The dialed destination number serves as a criterion for the route group to be used. The system can evaluate up to 24 digits in the dialed sequence plus the routing code. The system evaluates and routes the call based on a time of day schedule and the station's least cost routing class of service. |
Destination-Dependent Evaluation |
| The dialed digit sequence may be converted to a new digit sequence after evaluation, or it may be preceded by additional digits such as the carrier information of the destination. |
