WAN-Miniport driver 29

When using the German ISDN protocol 1TR6, the terminal device selection digit (EAZ) is

used to distinguish the ports. The EAZ consists of only one digit. This enables up to 9

ports to be distinguished.

Note: EAZ = 0 is a global call so every call is accepted by any port. Therefore, EAZ = 0

should be used only if no other similar devices are on the same ISDN line.

To specify the called port, the caller needs to attach the EAZ to the normal telephone

number. See the terminal description of your telecommunications system or consult the

telephone company.

If the shorthold mode is used with Multilink PPP, different phone numbers should always

be assigned to the RAS-Ports on the client side (see Shorthold and Multilink PPP

page 74).

Subaddresses

The ports can be further distinguished by subaddressing (up to 23 digits) if the ISDN

terminal is set up for subaddressing. This means that the call will not only be distinguished

by the destination code but also by an additional element, invisibly attached to the call

number.

In this case, both sides will have to work with subaddressing, or the terminals on both

sides will need to support subaddressing.

The calling subscriber will have to enter the SUB in addition to the normal telephone

number as a Destination SubAddress (DSA). When entering the telephone number in the

RAS telephone book, the SUB must be separated from the normal telephone number by

a vertical character [|], (the pipe symbol or [Alt] + [0], [1], [2], [4]).

Configuring phone numbers/extensions and subaddresses

1. Check the ‘Advanced Parameters’ option in the ‘Eicon WAN-Miniport Driver Setup’

dialog box.

2. Select the port to which you want to assign an MSN or EAZ.

3. Click ‘Change’.
