The ISDN SET-UP MENU provides for stored ISDN number set-up.
Note: this menu appears only if this router has an ISDN module installed and its Logical ISDN type is set to ISDN (not
Digital Leased).
1 - Dial Prefix
The Dial Prefix option is used when the ISDN P1700 is attached to an ISDN PBX. If a dialing prefix is required before
an outside line is obtained, the dialing prefix must be entered here.
Default: [none]
2 - Phantom Power Detect
Most NT-1s provide a signal to the connected ISDN device to indicate that the NT-1 is powered up and functioning
correctly. This signal is generally called phantom power. Some NT-1s do not support phantom power. This option
should be disabled if the NT-1 connected to the ISDN link module does not support phantom power.
If the P1700 is having difficulty obtaining a connection to the NT-1, this option should be disabled.
Default: [disabled]
Considerations: This option is not available when the WAN module is an ISDN type U interface.
3 - Force 56K
This option forces both B-channels on this router to use V.110 rate adaption for incoming and outgoing calls.
If the path to a destination number passes through a 56 Kbps digital circuit or the destination itself is a 56 K switched
digital service, V.110 rate adaption must be performed to allow the data to be sent at 56 K on the 64 K ISDN lines.
When an ISDN call is placed, the local ISDN service must be informed that V.110 rate adaption is required to fully
complete this connection.
Note: Adding a percent symbol "%" in the ISDN number will cause the P1700 to send a message to the local ISDN
service requesting V.110 rate adaption.
Default: [disabled]
