The following table describes the fields in this menu.

When you are finished, press [ENTER] at the message: 'Press ENTER to confirm or ESC to 
Cancel', the ZyXEL Device uses the information that you entered to initialize the ISDN line. It 
should be noted that whenever the switch type is changed, the ISDN initialization takes 
slightly longer.

At this point, the ZyXEL Device asks if you wish to test your ISDN. If you select Yes, the 
ZyXEL Device will perform a loop-back test to check the ISDN line. If the loop-back test 
fails, please note the error message that you receive and take the appropriate troubleshooting 
action.

Table 58   Menu 2.1 ISDN Advanced Setup

Phone 1/2 Call 

Waiting

The Call Waiting feature on your ISDN line works in exactly the same way as it 

does on a regular analog line. After hearing a call waiting indicator tone, press and 

immediately release the flash button on your telephone. This puts your current call 

on hold and answers the incoming call.

Calling Line 

Indication

The Calling Line Indication, or Caller ID, governs whether the other party can see 

your number when you call.  If set to Enable, the ZyXEL Device sends the caller 

ID and the party you call can see your number; if it is set to Disable, the caller ID is 

blocked.

PABX Outside Line 

Prefix

Enter the number for outside line access if the ZyXEL Device is connected to a 

PABX; otherwise, leave it blank.  The maximum number of digits is 4.

PABX Number 

(Include S/T Bus 

Number) for 

Loopback

Enter the S/T bus number if the ZyXEL Device is connected to an ISDN PABX. If 

this field is left as blank then the ISDN loopback test will be skipped.

Outgoing Calling 

Party Number

You only need to fill in this field if your switch requires a specific Outgoing Calling 

Party Number; otherwise, leave it blank.

ISDN Data

Enter the telephone number(s) assigned to your ISDN line by your telephone 

company. Some switch types only have one telephone number. Note that the 

ZyXEL Device only accepts digits; please do not include '-' or spaces in this field. 

This field should be no longer than 25 digits.

A/B Adapter 1

Enter the telephone number assigned to A/B Adapter 1 (PHONE1).

A/B Adapter 2

Enter the telephone number assigned to A/B Adapter 2 (PHONE2).

Hangup Silence 

Time(sec)

Most answering machines automatically terminate a call after a predefined length 

of silence. Specify the time in seconds that elapses before the answering machine 

drops the call when the ZyXEL Device receives tones from the switch and send a 

silence tone to the answering machine.

Data Link 

Connection

There are two types of ISDN Data Link Connection namely: point-to-multipoint 

and point-to-point. When you select point-to-multipoint, the TE1 value will be 

assigned by negotiation with the switch. When you select point-to-point, the TE1 

value will be assigned a unique value of 0.

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to 

save your configuration, or press [ESC] at any time to cancel.
