Supplementary Services
There are some common supplementary data services that are applicable to the Hypertec Router, namely:
•Calling Line Identification or Caller ID
•Multiple Subscriber Numbering (MSN)
Calling Line Identification (CLI) or Caller ID
CLI provides the caller’s telephone number when you receive a call. This information is provided by the network and not the caller and so can be used as a security measure to identify calls to be accepted and rejected.
You should order CLI if available.
Multiple Subscriber Numbering (MSN)
MSN allows multiple telephone numbers to be assigned to a single BRI connection. This allows you to assign specific numbers to specific devices.
For the Hypertec Router, there will be one LAN connected and one or two analog devices (e.g. telephone, fax). It is possible to give each device a separate number through multiple subscriber numbering, allowing calls to be routed to the correct analog device. This will also depend on the service you are connected to.
