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
|
||
