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.

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
