Remote Test Set (RTS-1)

RTS-1 Photo

Model RTS-1 is designed to allow security protected remote access to premise equipment and central office (CO) switches. The RTS-1 is an 8-port unit that can be linked with up to 6 expansion units providing access to a total of 56 ports. Each port permits an existing line be split between CO and CPE equipment. The RTS-1 maintains any existing connection between the CO lines and the premise equipment until accessed. The RJ-31X jack provides a pair for the CO side, which is mandatory, and another pair for the normally connected premise equipment, which is optional. Either loop- or ground-start lines may be utilized.

Any of the CO lines connected to the RTS-1 main or expansion units may be used to access the device. Upon the specified number of rings, the RTS-1 answers the call and provides an access prompt. The caller has a programmable amount of time (nominally 15 seconds) to enter a correct Test or Program code in DTMF (up to 10 digits). Once accessed with the Test code, the unit is placed into Test Mode, and test calls can be placed through any of the remaining ports on the main or expansion units.

The outgoing port can be seized, permitting the user to detect dialtone and DTMF dial through; or, the user can pass a number to the RTS-1 to be dialed, and have it automatically seize the line, detect dialtone, and dial the desired number locally, using either DTMF or rotary pulse signaling. During the test call, the RTS-1 can be commanded to generate a hook-flash. The accessor can disconnect from the test call on the outgoing port, and remain in Test Mode, ready to place a new call on the same or a different outgoing port.

A port can be tested for the presence of ringing voltage. The port number may be remotely queried.

The RTS-1 maintains a peg count of: Test Mode accesses, signifying the number of times the device has successfully received the Test code; Program Mode accesses, signifying the number of times the device has successfully received the Program code; access Failures, signifying the number of times the device has answered the line and timed out prior to receiving a correct Test or Program code; and access Answers, signifying the number of times the device has answered an incoming call. Each of these counts are three digits, and roll over from 999 to 000. These four counts can be remotely queried.

If the caller uses the Program code to access the RTS-1, the unit is placed into Program Mode, and permission is granted to change the device operating parameters and to perform self-tests.

Sound Clips

These audio recordings demonstrate how the RTS-1 is accessed manually, line identification is performed, test calls are placed, and the RTS-1 is released.

  1. Access. In this clip, the user dials into the remote location and gains access to the unit. Play Sound Clip
  2. Line Identification. In this clip, the user requests the RTS-1 line number which answered the incoming access call. This is not normally necessary unless the connected lines are in a hunt group with a common access number. The unit has already been accessed. Play Sound Clip
  3. Test Call. In this clip, the user makes an outgoing test call. The unit has already been accessed. Play Sound Clip
  4. Release. In this clip, the user has completed all desired tests, and disconnects from the remote unit. If the access line has positive disconnect supervision, this step can be skipped; the user can simply hang up on the unit. Play Sound Clip

The above example utilized dialing from the access point through the network to the end office. Other RTS-1 commands are available for redial. Additional sound clips demonstrating automatic RTS-1 access are available on the ARONTS Information page.

ARONTS Application

The RTS-1 ports can be located in the CO, and connected to lines with various classes of service. Insofar as test boards with these lines may already exist, connected to test telephones, the RTS-1 can use these existing lines. The RJ-31X configuration directly connects the telephones (CPE equipment) through to the CO lines when the RTS-1 is not accessed. This permits the test lines to be used locally with the telephones, and remotely with the RTS-1, without doubling the number of test lines required.

The RTS-1 may be accessed remotely either manually or with the ARONTS equipment. Test calls can then be placed on the connected CO lines of various classes of service. The dialing plan can be tested with local, long distance, and feature calls. The hook-flash option permits some features to be tested, such as conference calling and call waiting.

Command Summary

After the RTS-1 is placed into Test or Program Mode, DTMF digits are used to issue commands. Distinctive tone sequences acknowledge command acceptance or rejection due to an error. Commands 0 through 6 are available in Test Mode; all commands (0 through 8) are available in Program Mode. However, it is recommended that Test Mode be used unless the device's operating parameters are planned to be changed; this provides protection from accidental device modification.

Commands available from Test or Program Modes:

00:     Hangup
01:     Exit Test or Program Mode; provide Access Prompt
02tt:   Add a timeout to all line seizures (1, 2, 3, and 4 commands), 00-99 seconds
031:    Expect ground start lines; restore line to PBX if in use
030:    Use loop or ground start lines
1l:     Seize line l.  Exit with ###
2ldd...d#: DTMF dial telephone number dd...d at fast rate on line l.  Exit with ###
3ldd...d#: DTMF dial telephone number dd...d at slow rate on line l.  Exit with ###
4ldd...d#: Pulse dial telephone number dd...d on line l.  Exit with ###
##0:    Generate a Hook-Flash from within 1, 2, 3, and 4 commands
5l:     Listen for ringing on line l.  Exit with #
61:     Identify the incoming line
62:     Read the number of Test Mode accesses
63:     Read the number of Program Mode accesses
64:     Read the number of access Failures
65:     Read the number of access Answers

The following commands can be issued from Program Mode:

711rr:  Set the number of rings to answer line #1 to rr rings, 01-32
710rr:  Set the number of rings to answer lines other than line #1, 01-32
72m:    Set the number of Modules to m
73l1:   Inhibit answering of line l
73l0:   Enable answering of line l
741dd...d#dd...d#: Set the Test Code to dd...d (identical entry)
742dd...d#dd...d#: Set the Program Code to dd...d (identical entry)
751tt:  Set the Access Time to tt seconds, 01-99
752tt:  Set the Overall Time per session to tt minutes, 00-99
753tt:  Set the Disconnect Time to 0.tt seconds, tt = 01-99
76179:  Initialize all parameters
81:     Test EPROM
82:     Send 1234567890*#ABCD digits in DTMF
83 1234567890*#: Test DTMF inputs
84:     DTMF loop-around test

*:      Cancel current entry

In all cases:
        l = 1-8 line number
        If Expansion Modules are in use,
            replace l with two-digit ml to reflect line l on module m
        d = 0-9, A-D digit
        Red digits are literal DTMF keypad depressions
