MTXM which is used for rural areas. |
Combined switching is incorporated into a DMS-100 by some hardware |
additions and cellular software. Combined switching is designed to give a |
easy, cost-effective way to install cellular services to an existing host. |
Remote Switching is done by combining Remote Switching Center (RSC) with a |
Cell Site Controller (CSC). This combination is hosted by either a |
stand-alone or a combined switch. Remote Switching is designed for serving |
suburban centers, remote areas, or a small community and it gives extra |
flexibility for a growing system. |
All of these cellular switches have the ability to balance the workload |
among various cell sites. For example, if one site's workload reaches the |
programmable level of congestion, calls would be routed to nearby sites that |
can handle the extra calls. |
Cell Site Equipment |
Cell site equipment consists of a CSC and radio equipment. The CSC is |
controlled by the cellular switch and it controls radio equipment and |
maintenance tasks. The CSC will work on any MTX cellular switch because of |
the Remote Cluster Controller (RCC). |
The radio equipment consists of self-contained Radio Channel Units (RCU), |
antennas, transmitter multi-couplers and receiver combiners. |
By different program software a RCU can perform voice, control locating, |
and test functions. The self contained nature allows the RCU be remotely |
located to the CSC. A RCU has built-in circuitry for extended testing of the |
radio part of the system. |

Social Security Number Formatting |
================================= |
Shooting Shark 21 June 88 |
Certain types of computer-related fraud, such as creating dummy |
entries in payroll databases, require the creation of a false Social Security |
Number (SS#). Many employers attempt to detect "ghost" SS#s by running a |
verification program on them. In this article I will show how to defeat |
verification by creating a legitimate-looking SS#. |
First, some general rules to follow: |
o The middle two digits of a SS# can be odd or even |
if issued after 1965. All numbers issued before 1965 |
that have middle digits of 10 or above should be even. |
o So far, no SS#s have been issued with a first digit |
of 8 or 9. Very few numbers above 595 have been issued, |
so use caution. 700-729 were issued by the Railroad |
Retirement Agency a long time ago, and thus would belong |
to older people. No numbers in the 596-626 have been |
assigned yet (as far as I know), but 596-599 has been |
reserved for Puerto Rico, 600-601 for Arizona, and |
602-626 has been reserved for California. |
The next step is required only if it is necessary that the place of |
issuance (and thus, probably, state of birth or residence) match the SS#. In |
