Calling Line Indication
The Calling Line Indication , or caller ID, determines whether the other party can see your number when
you call. If set to Enable , the router 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
A PABX (Private Automatic Branch eXchange) generally requires you to dial a number (a single digit in
most cases) when you need an outside line. If your router is connected to a PABX, enter this number in
PABX Outside Line Prefix , otherwise, leave it blank.
Please note that the PABX prefix is for calls initiated by the router only. If you place a call from a device on
either A/B adapter, you must dial the prefix by hand.
PABX Number (with S/T Bus Number) for Loopback
Enter the S/T bus number if the router 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
If these fields are not blank, the router will use these values as the calling party number for "ISDN Data",
"A/B Adapter 1" and "A/B Adapter 2" outgoing calls. Otherwise, the individual entries for "ISDN Data",
"A/B Adapter 1" and "A/B Adapter 2" will be used as the calling party number. You only need to fill in
these fields if your switch or PABX requires a specific calling party number for outgoing calls, otherwise,
leave them blank.
The following diagram illustrates the
PABX Number (with S/T Bus Number) for Loopback and
Outgoing Calling Party Number fields for a router behind an ISDN PABX.
