Wide Bank 28
With the Wide Bank
®
28 family of products, standards-based M1-3
multiplexing takes a giant step forward. Wide Bank 28 is a family of
carrier-class solutions that significantly increases the number of DS1
service delivery ports that can be deployed at the same time that it dra-
matically lowers the per-DS1 port deployment cost.
Wide Bank 28 solutions can be deployed in conjunction with DCS,
SONET ADM, LDS, Frame Relay and ATM platforms. The Wide Bank
28’s small footprint solves the space problem that often limits how many
DS1 connections can be supported per rack. By using DS3 or STS-1
service modules to support the equivalent of 28 DS1 ports in a single
rack unit space, Wide Bank 28 solutions can support up to 672 T1 con-
nections in one 23-inch rack. For high-density applications, the Fan
Faceplate Option for the Wide Bank 28 makes it possible to increase
the number of Wide Bank 28 systems operating in a single equipment
rack to 40, providing support for up to 1120 DS1 ports.
Upstream management capabilities, high rack density and low T1
costs, all standard features of the Wide Bank 28 solution, combine to
provide a solution that delivers more control and capacity in less space
than competitive offerings — at a much lower cost.
