The RAD-1 allows remote access to loop start C.O. lines, analog PABX stations or any other 600 ohm audio device. This
can be very useful for many applications including using a local line to access an inexpensive WATS line (line extending),
utilizing your PABX/KSU features (DISA), service observing with Viking’s SO-24A, or remote access to paging systems.

A. Access
The RAD-1 will answer an incoming call on the first ring. The RAD-1 offers either unsecured access, or two levels of
secured access, designated “Priority 1” and “Priority 2.” “Priority 1” access may be used in applications where the RAD-
1’s outbound line is either a CO line or a PABX extension, whereas the “Priority 2” access mode is specific to applica-
tions where the RAD-1’s outbound line is a PABX extension.
1. Unsecured Access
If neither the “Priority 1”, nor the “Priority 2” access codes have been programmed, the unit is “Unsecured.” In this
mode, the RAD-1 answers the inbound call, double beeps, bridges the lines together, and the caller is given full and
immediate access to the outbound line. The caller may then dial un-restricted phone numbers. Anybody that calls
into the RAD-1 is given an extended line.
2. Priority 1 (unlimited) Access
When a “Priority 1” access code has been programmed, the RAD-1 answers the inbound call and prompts the caller
with a single beep. The caller is then required to enter a 6 digit access code. If the proper access code is not entered
within 20 seconds, the RAD-1 will triple beep and hang up. When a valid access code has been entered, the RAD-
1 will double beep and bridge the lines together providing access to the opposite line port. Anybody that calls into
the RAD-1 and successfully dials the “Priority 1” access code has unlimited access to the extended line, and may
dial un-restricted phone numbers.
Important: It is crucial that the installer and system owner understands the functions and capabilities of both the RAD-1
and the lines and/or PABX stations connected to the RAD-1, so that any and all toll fraud and other system abuse possi-
bilities are understood. This enables the installer and owner to make risk managing decisions about the system in which
the RAD-1 is put into. Viking Electronics Inc. is not able to assume responsibility since it is a function of the entire system
assembled by the installer/owner. A Viking TR-1 Toll Restrictor may be added to help prevent toll abuse if the PABX and
RAD-1 toll restriction is not adequate.
Programming the RAD-1 to...
1. ...disable outside line access
2. ...set the “Priority 1” access code to 456789
3. ...disable the “Priority 2” access code
4. ...enable SO-24A mode
Enter Digits
#44
456789 #45
#46

4. Remote Service Observation (Section D)
Note: The “Priority 1” and “Priority 2” access codes can work well together. As an example, one group of users can be
given the “Priority 2” access code, and hence only have the ability to dial within the PABX system. Another group of
trusted users (supervisors, for example) could be given the “Priority 1” access code, and thus have unrestricted remote
access to the PABX system, including outbound dialing.
3. Priority 2 (limited) Access
This mode is specific to PABX applications. When a “Priority 2” access code has been programmed, the RAD-1
answers the inbound call and prompts the caller with a single beep. The caller is then required to enter a 6 digit
access code. If the proper access code is not entered within 20 seconds, the RAD-1 will triple beep and hang up.
When a valid “Priority 2” access code has been entered, the RAD-1 will double beep and bridge the lines together
providing access to the opposite line port. The caller is then given limited access, and may only dial extensions and
features within the PABX. If the caller attempts to dial the PABX outside line number (programmable, but typically
a 9) to place a call outside of the PABX, the caller will hear a triple beep and be immediately disconnected. This
effectively prevents toll fraud and system abuse. Important: If the PABX utilizes any special direct trunk access
codes in addition to the outside line number, the RAD-1 can not prevent toll fraud and system abuse on a “Priority
2” access call.
