2.4 CENTRAL SWITCHING EXCHANGE
A. The Central Switching Exchange (CSE) shall be microprocessor-controlled and include
pulse amplitude modulators for internal speech transmission. The CSE mainframe shall
be modular, expandable for optimum station configuration, and capable of future
expansion by adding additional station line cards and/or exchanges as required. The CSE
shall be a fully non-blocking system to allow simultaneous telephone handset to telephone
handset communications paths as required. Through the use of expansion modules, the
system capacity shall be easily expanded to accommodate future requirements. The CSE
shall provide direct dialing and private two-way telephone communications between all
locations equipped with ATELs or STELs as shown on the Drawings.
B. The system should have complete interconnect capabilities to the local telephone
company central office lines. To accomplish this, the system must be registered with the
FCC and have a registered ringer equivalence number. (Note: Provide ringer equivalence
number as part of the submittal.) It must also be capable of interconnecting to a PABX. It
shall be possible to transfer any interconnected circuit to any station in the system.
Access to outside lines shall be limited to certain authorized telephones via software
programming.
C. The integrated communications system shall provide for the direct connection of outside
trunks. Systems that require the use of line amplifiers shall not be accepted. The system
shall be capable of connecting to 32 loop start central office trunks or KSU/PBX
extensions.
D. The system shall provide all standard telephone company signaling to interface with other
special services such as off-premises extension, Watts, and Centrex.
E. The Central switching Exchange shall have the following components. Provide quantities
of each component as required for a complete and operable system as specified in the
Contract Documents:
1. Card Cage: Provide capacity for holding all necessary control and line cards, as
well as paging amplifiers. Provide expansion chassis if required.
2. Memory: Non-volatile user-configurable memory, time-based system
reconfiguration, and built-in diagnostics.
