|
In the past, many misconceptions have been made of the legendary
|
|
REMOBS system. The term has been used and abused. It used to be known as
|
|
REMOB, rather than the proper REMOBS, which stood for Remote Observation. The
|
|
REMOBS is a REMote service OBservation System manufactured by Teltone, a
|
|
company which makes various telephone equipment peripherals.
|
|
|
|
REMOBS has a number of features. The REMOBS permits evaluation of
|
|
equipment or employee performance. It allows observation of subscriber lines,
|
|
CO, toll, and E&M trunks, repair bureaus, and operator positions. It can be
|
|
portable or set up as dedicated remote terminals. The observer console can
|
|
sample entire networks. REMOBS is compatible with all types of switching and
|
|
transmission media.
|
|
|
|
The purpose of the REMOBS system is to measure performance and
|
|
service provided to customers in an impartial and unbiased manner. By
|
|
monitoring the subscriber connections throughout the network switch, this can
|
|
be achieved. The customer experiences are recorded and statistics are derived
|
|
to provide service level indices.
|
|
|
|
REMOBS is compatible with all switching systems including Step by
|
|
Step, Crossbar, and electronic equipment. In each situation, it can observe
|
|
almost any transmission point such as subscriber lines, inter- and
|
|
intra-office trunks, toll trunks, E&M trunks, repair bureaus, commercial
|
|
offices, and operator positions. The console operators can observe by phone
|
|
line, from one location, any switch location/CO with the remote unit
|
|
installed.
|
|
|
|
The M-241 system (which includes the console and remote terminal)
|
|
observes up to 40 circuits, but can scan up to 100 lines with a remote
|
|
terminal. The terminal may observe up to 5 locations simultaneously, with a
|
|
capacity to observe 500 circuits at any one time.
|
|
|
|
The REMOBS system can observe all remote terminals at any switching
|
|
system location through the console controls, making it feasible to observe an
|
|
entire network. Remote terminals are equipped with plug-in connectors so they
|
|
can be moved routinely to observe desired locations.
|
|
|
|
The M-241 Remote Terminal: The remote terminal is located at the point of
|
|
========================== observation. It may be ordered in portable or
|
|
dedicated configuration. The remote terminal remains inactive until accessed
|
|
by the controlling console. The remote unit is 6.5" high, 22.88" wide, and
|
|
11.7" deep, arranged for relay rack mounting.
|
|
|
|
The M-242 Observer's Console: Console operators access the remote terminals
|
|
============================= through telephone lines. Access to the remotes
|
|
is limited to console operators who know the access number, timing, and four
|
|
digit security code. Additional security is available with the optional
|
|
security dialback feature. The System automatically scans observed circuits.
|
|
The first circuit to become busy is selected and held by the system until the
|
|
necessary information is secured, the operator presses the reset button, or
|
|
the calling party goes on-hook. Timing circuits automatically drop the call
|
|
100 seconds after the calling party goes off-hook or, if answer supervision is
|
|
present, 15 seconds after the called party answers. The console itself looks
|
|
very much like a cash register. Where the digits are normally, there are
|
|
places for the trunk identity, called number, stop clock, and memory. The
|
|
pushbutton controls consist of the following: power (key switch), hold
|
|
buttons, select buttons, calling party, called party, display hold, clear,
|
|
O.G. line, auto reset, reset (manual), read (stop clock operate), talk, voice
|
|
exclusion, memory, plus a standard touch-tone keypad with the A, B, C, and D
|
|
keys. There are 2 monitor jacks, a volume control and, for the primitive
|
|
lines and switches, a rotary dial next to the touch-tone keypad. The
|
|
operator's console stands 2.25" in the front and 8.25" in the back; it's
|
|
17,25" wide and 16.5" deep.
|
|
|
|
The observation system network is set up in the following manner.
|
|
The operator observer is in an observing center at the local Central Office
|
|
with the M-242 REMOBS Central Console (which looks like a telephone to the
|
|
Central Office). Through the standard telephone network, communications
|
|
occurs between the console and the remote. From the CO, through the incoming
|
|
circuitry, it goes through the connector to the M-241 REMOBS Remote Terminal
|
|
(which looks like a telephone to the access line). From there the connection
|
|
is made to the circuits to be observed including the subscribers lines,
|
|
line-finders, toll trunks, repair lines, etc.
|
|
|
|
The information provided is both visual and audible. The visual
|
|
display, showed on the panel, includes the identity of the remote terminal,
|
|
the identity of the observed circuit, the signalled digits (up to 52), the
|
|
status of the calling and called parties (on/off-hook), and the timing of the
|
|
call. The audible information (which is provided through headset or handset)
|
|
includes the call progress tones for disposition (dial tone, type of
|
|
signalling, 60 IPM, 120 IPM, ringing, answer, etc.) and voice transmission
|
|
(calling and called parties).
|
|
|
|
The REMOBS system is very much different from often-misconceived
|
|
system known as 4Tel made by Teredyne. REMOBS is very much different from the
|
|
dial-up - enter 1 code - be given instructions simplicity of the 4Tel but it
|
|
still has the legendary capabilities of listening in remotely.
