The least-cost router
The liberalization of the European telecommunications market has led to the
availability of a variety of providers (network operators) that often offer a
wide range of different charges. These providers also provide the option of
the preselection of a given network or the placement of long-distance calls
on a call-by-call basis without a contract with a specific provider. The prefix
of the provider must be dialed to access the desired network on a call-by-call
basis. The normal telephone number is dialed after the network identifica-
tion prefix.
Unfortunately, the most inexpensive rates vary from provider to provider
depending on the time of day and region. In the morning Provider 1, Provider
2 in the afternoon and possibly Provider 3 for international calls. To always
have the most economical connection for telephone calls, surfing the Internet
or transferring data to other networks, it would be necessary to decide which
provider is the least expensive before each connection. A
ELSA LANCOM
Wireless IL-11
does this for you. Least-cost routing (LCR) is the function for
this task. You define once which providers have the most favorable charges
for your purposes, and the device automatically selects the most economical
provider for you, (regardless of whether you are using the router, the
LAN-
CAPI
etc.).
