SSWC - Bell Research Report (Vol II)
All research gathered, tested and mastered by the original
members of SSWC:
Chance - The Technician - Cellular Phantom
SSWC presents our latest text file continuing our discussion
on Bell Operating Departments. Note that information in
this file is subject to change. However, we will try to keep
you updated as much as possible.
We will begin by discussing an important department of Bell,
known as the Maintenance Center (MC) or Special Service Center
(SSC). The MC is responsible for verifying and coordinating the
transfer of special service activities between the Construction
Work Group (CWG) and the Central Office Work Group (COWG). The MC
or SSC will maintain control of all special service transfers.
Note: When using an approved transfer switch, testing of
Plain Old Telephone Service (POTS) services will be
performed by the CWG. The MC need only test services
classified as type "B". (This type of classification
is generally used on the Computer System for Mainframe
Operation (COSMOS) mainframe).
The MC will receive a copy of the cable transfer and associated
work orders from the Loop Assignment Center (LAC) prior to the
scheduled start date of the transfer. They will deal with any
unrecognized problems (such as clearing defective pairs, if
requested by the Distribution Service Design Center (DSDC), and
giving notification of what pairs have been or cannot be cleared)
that would require new pair count assignments.
The MC shall arrange with the CWG, Frame Control Center (FCC),
SSC, and other necessary departments for the transfer of special
and designed services that require release or special handling.
During the transfer of these services, the MC will maintain
communication with all personnel involved in the transfer
activity.
The MC or SSC shall coordinate the release and transfer of
special and designed services designated as "B" services. The time
and date for each service release shall be recorded on the MC copy
of the Special Service Protection List and Defective Pair List.
Note: Time and date of release must be negotiated in advance
of the cable transfer. No work shall be permitted on
service requiring a release until a method of procedure,
including release date and time and personnel required,
has been established by the MC and approved by the
customer and SSC control office responsible for those
services. When the MC receives work of those specific
or out-of-the-ordinary release requirements, the
Construction Management Center (CMC) supervisor, FCC
supervisor, and other necessary work group supervisors
must be notified in advance so they can begin work on
the transfer.
The MC shall test all affected special and designed services
completed by the CWG as the transfer progresses. The CWG need not
wait for verification by the MC, unless problems are encountered.
The CWG will inform the MC of progress. The MC shall have the
authority to stop the transfer procedures at any time if extensive
trouble reports develope. If this occurs, the MC supervisor will
lead an investigating committee to determine the cause of trouble
and to recommend corrective action.
After all work is completed, the MC will issue a final closing
number for the completed transfer. The MC will notify the FCC that
the transfer is complete and will give them the closing number.
The MC will post the Cable Transfer Form as complete and will
forward the transfer, including changes, and Defective Pair List
to the LAC.
We will now discuss the uses of the Cable Transfer Administration
(CTA), and how they operate at a successful level.
The general functions and responsibilities of the CTA work group
is to provide flexibility in the design of the cable network,
existing cable pairs are transferred for one cable count to another
cable count. This is commonly referred to as a cable transfer or
cable throw. The transfer occurs in a splice and involves
disconnecting pairs of wires beyond the splice from one feeder
cable count and reconnecting then to a different feeder count.
The result is that the count of the pairs beyond the splice will
change. The configuration, identification, and possible transferring
of working cable pairs are complex and time-consuming. The work
is further complicated by the many functions required of other
work groups. To ensure that these operations are performed free of
service interruptions and with maximum efficiency, timing and close
coordination among all the work groups involved are mandatory.
The same coordination is required to complete drop wire re-
connections (line transfers). The Cable Transfer Committee (CTC)
is also responsible for organizing this work in a timely manner.
As soon as practical, after the line transfer have been completed,
the old cable should be cut off and removed. (Their is more
hardware work involved in this process, however we regret that
we have not yet been able to fully research and understand what
further hardware applications are used).
In order for the Cable Transfer Committee to obtain a high
degree of transfer efficiency, all committee members must attend
committee meetings on a selective basis and monitor the published
minutes (in other words review information from past meetings).
Higher management will be able to evaluate the effectiveness of
the transfer committee. The number of jobs completed as scheduled
and the ability of the committee to identify problems should be
monitored as a measure of committee success in scheduling and
completing cable transfers.
The use of these procedures will reduce customer trouble reports
and the overall cost of cable and line transfers and will permit
balancing the work force and work load for all groups involved.
By completing cable transfers promptly, in accordance with the
time schedule, changes to transfer sheets will be minimized, the
need for rerunning cables will be reduced, testing cables can be
properly scheduled, and time spent on field work can be shortened.
The errors, frustrations, and probability of cable troubles
associated with delays in this kind of work can be virtually
eliminated.
A Cable Transfer Committee must be established in each network
distribution service/construction district to ensure close
coordination and proper timing of cable, line, or station transfers.
Districts that cover a large service area (having more that one
Loop Assignment Center or Maintenance Center) may require more
than one committee.
When scheduling transfers, consideration must be given to work
tours and peak load periods (busy times of the week) of all work
groups to optimize the continuity of the cable transfer activity.
Consideration must also be given to time required by the CWG
to complete preliminary work, by the LAC to analyze and lay out
the transfer, by the Circuit Provision Center (CPC) to check the
design of special services, by DSDC, Construction Management
Center (CMC), and installation to make the resulting changes, and
by the MC and/or SSC to negotiate with special service customers.
The Cable Transfer Committee must negotiate all completion dates.
The transfer committee chairperson will monitor and take action
on excessive time intervals for all work groups. Transfers that
involve an extremely large number of working circuits may require
scheduling in smaller segments. Transfers should be scheduled to
maintain continuity until wire work is completed. The committee
is responsible for all special scheduling. Offices with
mechanized assignment records such as COSMOS or TIRKS require
more strict scheduling due to transaction restrictions.
Sequence transfers and the reusing of counts cleared on previous
transfers may also require more strict scheduling. Cable
transfers worked via COSMOS must be closely monitored to avoid
long-term storage of cable transfers in the data base.
Long-term storage causes changes for the FCC and CWG, thereby
causing lost time. The committee will make preliminary arrange-
ments for the transfer of special and designed services. The LAC
will provide a list of all special services, by Common Language
Circuit Identification (CLCI), that are in the affected cable
count to the DSDC prior to scheduling the transfer in the firm
period. The DSDC will forward the list to the CPC along with the
new and old cable makeup for the reissuance of new Work Order
Record Detail (WORD - The work authorization and layout card
for designed special services) documents and redesigns, if
necessary.
After the new WORD documents are received, the FCC will bring
the Work Authorization (WA - The first page of the WORD document)
to the CTA committee meetings. The WA copy will contain the work
description and associated notes for the transfer and, most
important, will give the circuit classification code "A" or "B".
Next we will discuss information concerning the Telephone
Outside Plant. This brief discussion will inform you exactly what
path cables take from the CO to the subscribers residence.
This path is as follows:
1 Main Distributing Frame (MDF)
2 Tip Cables
3 Cable Vault
4 CO Manhole
5 Main Conduit
6 Subsidiary Conduit
7 Insulated Joint
8 Main Distributing Terminal (MDT)
9 Riser Cable
10 Distributing Terminal
11 Anchor Guy
12 Aerial Cable Cross Connecting Box
13 Telephone Company Owned Pole
14 Aerial Cable
15 Strand (one cable)
16 Joint Use Pole Electric or Telephone
17 Terminal
18 Splice
19 Electric Wires
20 Urban Wires
21 Dropwire
22 Main U.G. Cable
23 Stub
24 Rear Wall Cable
25 Buried Cable
26 Cribbing
27 Block Pole
After completing this sequence the cables will then run into
the residence, providing telephone service.
