The CBM CO/SAM Integral Modem (SAM/IM) provides a much more cost
effective and reliable alternative to the traditional method
of point to point CO/SAM trunking connections. Prior to the
introduction of the SAM/IM technology, the common method for
point to point dual facility trunking (56k or fractional T1) was to
install dual external modems and failsafe switching equipment at
both the data center and central office locations.
The "old" method for dual facility connections required the purchase
of 4 modems and 2 failsafe switches for every CO/SAM trunk
connection. The installation of this equipment in the central office
was time consuming and expensive, but also required precious relay
rack space, separate DC power fusing/wiring and front equipment
drawing updates. The data center side required expensive rack
mount equipment and precious floor space.
CBM has engineered the SAM/IM module so that it integrates the
dual 56kb modems and failsafe switching technology on a single
printed circuit card that is small enough to be installed inside the
CO/SAM located in the central office and inside the Lucent
Technologies Datakit node located in the data center.
The SAM/IM module provides the most efficient and cost effective
method for quickly deploying CO/SAMs that require reliable
redundant trunk connections.
