Using Specific Switch Parameters
Your service provider may require specific details about the parameters for the switch you are
connected to. The parameters will depend on the service you are selecting. The following information
provides the switch settings that are appropriate for the Hypertec Router connectivity.

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.
