Wide Bank 28 Wide Bank 28 Space-efficient, cost-effective digital service connection for a variety of platforms and applications ® With the Wide Bank 28 family of products, standards- single equipment rack, providing support for up to 1,120 based M1-3 multiplexing takes a giant step forward.The DS1 or 840 E1 ports. Wide Bank 28 is a family of carrier-class solutions that sig- nificantly increases the number of DS1/E1 service delivery Upstream management capabilities, high rack density, and ports that can be deployed at the same time that it dra- low T1/E1 costs, all standard features of the Wide Bank 28 matically lowers DS1/E1 port deployment costs. solution, combine to provide a solution that delivers more control and capacity in less space than competitive offer- Wide Bank 28 solutions can be deployed in conjunction ings – at a much lower cost. with DCS, SONET ADM, LDS, Frame Relay and ATM plat- forms.The Wide Bank 28’s small footprint solves the space problem that often limits how many DS1 or E1 connec- tions can be supported per rack. By using DS3 or STS-1 service modules to support the equivalent of 28 DS1 or 21 E1 ports in a single rack unit space,Wide Bank 28 solutions can support up to 672 T1 or 504 E1 connections in one 23-inch rack. For high-density applications, the Fan Faceplate Option for the Wide Bank 28 makes it possible to configure up to 40 Wide Bank systems operating in a Sales Representative: Phone/ 303-218-5707 5395 Pearl Parkway E-mail/ sales@carrieraccess.com Fax/ 303-218-5680 Boulder, Colorado 80301 www.carrieraccess.com Features for the Wide Bank 28 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 deploy- ments,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 incre- ments 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 fuseless high-voltage line protection all contribute to very low downtime and very high system reliability.
