CBM CrossOver Security Switch (COSS)
During the last few years, the telecommunications
industry has been faced with the formidable challenge of
increasing network access security. Now that the
colocation of service providers has become a reality, the
need to protect console terminal access to every
central office switch or network element has become
extremely critical. To meet this challenge the installation
of sophisticated security servers, that continually
authenticate secure ID's for all access, has become
commonplace in every central office.
The implementation of strict access control has created
another problem for the telco industry. It needed an
efficient and cost effective method for bypassing security
access just in case an emergency condition arose
whereby the normal secure ID authentication process
failed. In the event that the security server became
inoperable or the communication link was broken,
emergency "non-authenticated" access to the console
terminal on the central office switch or network
element would still be allowed. They not

only needed a switch that could be used to bypass security, but one
that would also send a major alarm to network operations
if security was bypassed or the console terminal
was disconnected.
The CBM CrossOver Security Switch (COSS) was
developed to specifically address the occasional, yet
critical need to bypass security on the console terminal
of the CO switch.
Security Normal Mode
Normal mode of operation. All console terminal access must be
authenticated via the secure ID server.
Security Bypass Mode
In the event of an emergency condition, the bypass switch
may be used so that the secure ID access is not
required by the console terminal. However, an alarm is
set when security is bypassed. The disconnection of any
cables from the Crossover Security Switch will also set
an alarm.
