Carrier-Quality T1/E1 Service
Delivery Platform The
Wide Bank® 28/DS3 and /STS-1 multiplexers help carriers balance capital and
operational expenses and space limitations while ensuring reliability and
performance. Compact in size with best-in-breed protection and redundancy,
Wide Bank is the preferred port-maximizing platform for T1 service delivery
from a variety of DS3 or STS-1 equipped devices such as SONET Add/Drop
Multiplexers (ADMs), voice switches, data switches and wireless radios. The
Wide Bank 28 helps carriers meet the high-availability requirements of
today’s critical service needs while also delivering more control and
capacity in less space than competitive offerings – at a fraction of the
cost of traditional solutions. |
Reduced space requirements
The Wide Bank 28 dramatically reduces the amount of space required to deploy
T1/E1 by supporting up to 28 DS1or 21 E1 service connections in only a
single rack unit of space. Older generation equipment requires an entire
rack full of equipment to provide as much capacity. The Wide Bank 28’s
reduced space requirements make it cost effective to deploy DS1/E1 ports to
support growing requirements in a variety of environments. While saving
space is an important consideration for most deployments, Wide Bank 28’s
small footprint is particularly beneficial for sites such as
pops, collocations, central offices, and digital loop carrier cabinets, where
space is at a premium and the size of previously available equipment makes
expansion impractical or prohibitively expensive.
Lower-cost for deploying and delivering services
Wide Bank 28 solutions make it possible to provision more T1/E1 ports in
virtually any platform,
greatly increasing the maximum number of ports that can be deployed and
services that can be
delivered to customers. Adding the Wide Bank 28 to a platform results in a
significant reduction in
cost per DS1/E1.The bottom line? More revenue generating opportunity at a
lower cost than with
competitive solutions — and in much less space.
Robust remote management facilities
The Wide Bank 28 solution offers unsurpassed remote management facilities
that eliminate the need to physically replace cards or set switches to
isolate and differentiate among equipment, line, electronic, and network
errors.
Support of Simple Network Management Protocol (SNMP) enables integration of
control of the unit with popular SNMP management systems through a direct
Ethernet connection. A Command Line Interface (CLI) provides remote
management via an RS-232 Telnet or local management connection. Bit Error
Rate Testing (BERT) capabilities automatically test internal data paths.
Remote terminal management allows electronic protection switching of
individual interfaces, eliminating costly truck rolls and service
interruptions.
Modular design to accommodate evolving needs
Demand for services is growing rapidly, making scalability a must for
cost-effective, fast, and efficient network expansion. Wide Bank 28
solutions accommodate changing needs with a modular design that allows
deployment of from 4 to 28 DS1 ports in 4-port increments, or 3 to 21 E1
ports in 3-port increments to accommodate demand for more capacity as it
occurs. When additional ports are needed, capacity can be increased
quickly and easily simply by adding one or more DS1 or E1 interface
cards (to a maximum of seven cards per Wide Bank 28).
Unique sparing and redundancy implementation for high reliability
The Wide Bank 28 system’s modular approach to sparing and redundancy reduces
downtime and
helps ensure that the system remains available. The typical approach to
low-speed (DS1 or E1)
hardware redundancy is to use an entire spare low-speed card to replace a
single channel that fails,
leaving the remaining channels unprotected in the event of another failure.
With Wide Bank 28, if a single channel fails, only a single channel on
the spare low-speed card is used, ensuring that there will be a spare
available to provide backup if another low-speed channel should fail.
Additional features
such as hitless electronic and circuit protection, dual controllers, dual
power supplies with dual power inputs, and fuse less high-voltage line
protection all contribute to very low downtime and very high system
reliability. |
