Carrier Types |
| Since in many cases individual carriers provide specific connections and conditions at different tariffs (sometimes with different signaling methods), least cost routing can be used to automatically select the most economical connection or most economical carrier for each outgoing phone call. |
| The following carrier types and networks are available for implementing least cost routing (LCR). |
7.1.1.1 |
Mercury Communications Limited Single Stage |
Definition |
| With this type of LCR, a prefix is used to dial the desired network carrier and the station number is subsequently dialed. |

7.1.1.2 |
Mercury Communications Limited Two Stage |
Definition |
| With this type of least cost routing, the system initially selects the carrier using a configurable access code (as with single stage). Afterwards, the system also waits for a connect (synchronization during timeout). |
| After the connect, the system transmits an authorization code and the destination station number as DTMF signals in the B channel. |

Dial-In Control Server (DICS) |
Definition |
| With this type of least cost routing, the system uses the routing table to determine whether the call should be made via the DICS or the public network. If the DICS is used, the system dials the DICS using a configurable access code and an authorization code and transmits the station number dialed by the station in the SUB address (on the D channel). The DICS checks the authorization based on the CLIP information and the transmitted authorization code. |
| If the DICS is not present during the first connection setup, the system reroutes the connection to the public network. This alternative access must be configured. |

Corporate Network (CN) |
Definition |
| A corporate network is an alternative network, such as a company-owned network, that is connected directly to the HiPath 3000/5000. |
| The LCR function determines the corresponding trunk group based on the station number dialed and then routes the call either via the trunk group in the public exchange or via the trunk group in the corporate network. If necessary, the system translates the station number. |

7.1.1.5 |
Primary carrier |
Definition |
| When a trunk is seized by the primary carrier, simplified dialing is performed by en-bloc dialing or by dialing individual digits into the public network. |
| If primary carrier was the method selected in the outdial rule table, forwarding in the trunk group table is not performed for entries after the route configured as a primary carrier. |
