ISDN-name-list

Remote station settings

The names entered in the name list are needed by the router to determine the correct remote station and corresponding layer name. The name list is also used for the callback function.

The ISDN name list can contain 64 different device names and might, for example, have the following appearance:

Device-name Subscriber number B1-HZ B2-HZ Layer-name Callback
GLASGOW 875463 180 0 PPPHDLC On
LONDON 040785647 20 20 DEFAULT off

Below is a detailed description of the meaning of each field:

Device-name In the Device-name column, you can enter an original remote station name, which you must then assign to the relevant remote station via the Name option in the Setup menu
Dialup remote Telephone number of remote station
WAN layer In this column, a name is stored that must also be entered in the layer list. This establishes the transfer protocol required for this connection.

O Callback options

Off No callback is made
Looser The router stops attempting to establish a connection when there is a call from this remote station (reciprocal call establishment). This setting must be used when a callback from the remote station is expected.
Auto (neither applicable to Windows 9x nor Windows NT) The connection will be rejected and a direct callback will be initiated if the remote station is specified in the number list. This means that the caller is not charged. If the remote station is not specified in the number list, a callback will be negotiated in a protocol negotiation (ELSA or PPP). A charge of one unit is incurred for this.
Name This setting forces a protocol negotiation. This enables call number protection to be set in the number list and also a callback to be started using the protocol negotiation. A charge of one unit is incurred for this.
O The special dialing characters in the table below can be entered along with the call number in the name list, round robin list, or logical dial prefix. They control the line access, the use of a semipermanent leased-line connection or determine the interface to be used for the connection:

# Trunk seizure (only with some PBXs)
F The remote station can be reached via the leased-line connection only. Syntax: F[channel:][subscriber number] The channel and subscriber number are both optional. In the case of several leased lines, the channel specifies the B-channel to be used. Depending on the setting in the channel list, the subscriber number indicates whether a dynamic channel bundling or backup line is to be realized over the dial-up connection.

  When S or S2 is appended to the call number, the semipermanent connection (SPC) is activated for the D-channel protocol 1TR6.

NOTE: You must subscribe to an SPC through your telephone company; such connections are generally billed with a flat rate.

NOTE: If you forget to append an S or S2, the SPC will behave like a standard dial-up line and your charges will be unnecessarily high. The telecommunications providerthen charges you the fixed charges and the dial-up line charges incurred during the time the line was used.
