Compatibility...For Ease of Implementation
CO/SAM 128 supports up to four TERM32 (or UN315)
cards. To make room for the additional TERM32 cards, a
newly designed, more compact power supply has been
incorporated in the CO/SAM 128 design package. All other
parts or subassemblies are interchangeable between the
two SAMs. Thus the migration from CO/SAM 64 to
CO/SAM 128 will allow you to maximize your existing
investment in addition sparing requirements.
The Back Panel of the CO/SAM 128 no longer requires
internal cables to connect from the backplane to the 50
pin Telco connectors. The I/O Cards have been designed
to connect directly to the backplane. The Telco
connectors readily accept mini 50 pin digh-density
locking cables. These locking cables ensure that the
connections to CO/SAM 128s mounted on sliding shelves
will remain secure thus maintaining system integrity.
Expandability...For Future Growth
CO/SAM 128 is designed with system expansion in mind.
An expansion CO/SAM 160 with up to five TERM32 cards
can be daisy-chain connected via an expansion port
incorporated on the CO/SAM 128 Back Panel. You can
add up to 160 additional ports for a total of 288 ports
per nodal trunk interface. This expansion capability
provides the lowest cost per network element
connection available for Central Offices using Lucent
DATAKIT BNS/VCS® data switching technology.
Upgradeability...For Investment Protection
To facilitate your migration from CO/SAM 64 to
CO/SAM 128, we offer a system upgrade program. You can
tell us your requirements for CO/SAM 128s or we will
survey your central office network and develop a migration
schedule, which will absolutely minimize transition downtime
and maximize your system's expansion and growth potential.
Remember, upgrading from CO/SAM 64 to CO/SAM 128
allows you to protect your investment in existing
facilities, DSU/CSUs, and fail switch technology while
accommodating increased demand for inexpensive
network element connections.
